Defense-tech construction faces unique hiring challenges due to strict security requirements, a shrinking pool of cleared professionals, and competition from commercial tech industries. Here's what you need to know:
To address these issues, defense-tech firms are turning to specialized recruiters, scalable hiring models, and skills-based hiring initiatives. Retention strategies focus on continuous training, clear career paths, and emphasizing the mission-driven impact of the work.
Defense-Tech Talent Crisis: Key Statistics and Workforce Challenges
Tackling hiring challenges is essential for meeting the precision and efficiency demands of defense-tech construction. Since 2014, jobs requiring security clearances have grown tenfold, yet the pool of qualified candidates has expanded by less than 10%. This disparity disrupts timelines for secure data centers and classified facilities alike.
The financial toll is immense. A typical aerospace and defense company loses between $300 million and $330 million annually in productivity due to talent shortages. For construction projects, these gaps translate into delays. For example, 10 out of 15 major Department of Defense (DoD) IT projects have faced delays ranging from one month to five years. The problem worsens as experienced professionals leave the industry.
The industry’s shortage of cleared professionals is driven by several factors. About a quarter of the aerospace and defense workforce is at or beyond retirement age, creating a "retirement cliff" that strips the field of decades of expertise.
At the same time, cleared engineers are leaving defense-tech at twice the rate they’re entering, drawn to commercial sectors like AI and data science, which offer faster-paced innovation. The issue isn’t just about pay - it’s also about the work environment. Lars E. Jacobsen, Global VP Specialisations at Randstad, explains:
The assumption that security clearance keeps your engineers tied to the industry is no longer safe. Commercial tech companies see the value in your talent pool and they are not waiting for applications to come to them.
Working in Sensitive Compartmented Information Facilities (SCIFs) adds to the problem, as it makes it harder for professionals to build visible, career-enhancing profiles. If trends continue, the defense-tech industry could face a shortage of up to 1 million engineers by 2030.
Federal compliance introduces complexities that most commercial projects don’t face. Everyone working on defense-tech construction must be a U.S. citizen aged 18 or older, with foreign nationals barred from clearance processing. Joint ventures must also clear Key Management Personnel (KMP) before any project work begins. For Department of Energy projects, workers need "Q" or "L" access authorizations, which involve in-depth federal background checks into factors like conduct and foreign influence.
Prime contractors are further tasked with ensuring that all subcontractors and specialty trades meet stringent cybersecurity and data-handling standards, which complicates the vetting process for additional talent.
By 2026, compliance with Cybersecurity Maturity Model Certification (CMMC) and DFARS will no longer be optional - it will be a key qualifier for bidding on projects. Industry analysis emphasizes that CMMC readiness has shifted from an IT concern to a critical part of bid strategy. Construction teams must now be trained in secure data handling for Controlled Unclassified Information (CUI), including facility drawings and site security plans, before accessing project workflows.
These regulatory hurdles are compounded by intense competition for talent.
Defense-tech construction competes directly with industries like data centers, energy infrastructure, and advanced manufacturing for the same pool of skilled workers. While commercial firms can onboard candidates in weeks, the defense-tech process often takes more than eight months.
Education pipelines also favor commercial tech. Over 60% of technical talent at major firms like Meta, Apple, and Google hold degrees from top-ranked universities, compared to just 20% of DoD technical staff. Between 1998 and 2021, over 75% of the DoD’s technical talent exited the organization.
Additionally, defense organizations often prioritize operational experience over technical expertise for senior leadership roles. This creates a ceiling for technologists who might find greater opportunities in commercial firms. The defense sector’s relative isolation from tech hubs further slows the adoption of emerging technologies and limits the exchange of ideas that is common in more dynamic industries. As a CSIS analysis points out:
The defense enterprise will continue operating largely as a set of industrial-age institutions that leverage technology ineffectively rather than as twenty-first century organizations where technology and technologists are managed like a strategic asset.
Defense-tech construction isn't just about traditional building expertise - it demands a workforce with specialized skills and clearances. While workforce shortages are a challenge across the construction industry, the unique requirements of defense-tech projects make these gaps even more pressing.
Defense-tech projects need a mix of advanced technical expertise and operational know-how. Key roles in demand include digital engineering specialists, lean construction professionals, and experts in modular and off-site construction. Labor shortages have taken a toll, slashing productivity by over 40% and causing material delays, increased labor costs, and project timelines to stretch by 20–25%. These challenges are echoed across the sector, where wage pressures and reduced efficiency are widespread.
Additionally, data and analytics experts play a vital role in streamlining operations. By using intelligent simulation software and real-time data, they help pinpoint efficient critical paths for projects. At the leadership level, strategic decision-making in the C-suite ensures that workforce management is treated as a top priority.
Building secure facilities adds another layer of complexity, requiring professionals with a deep understanding of both physical and digital security systems designed for classified environments. This calls for expertise in integrating these systems while adhering to strict security and compliance standards.
The industry is also shifting toward competency-based hiring, where demonstrated mastery of digital tools outweighs traditional job titles. This approach is crucial for modernizing defense capabilities, as mandated by Congress, and requires a workforce skilled in digital engineering for secure operations. However, with the retirement of an estimated 3.2 million baby boomers in 2020, the pool of experienced talent has significantly shrunk.
To address these challenges, expanding recruitment efforts is critical. Programs targeting non-traditional candidates, such as veteran-transition initiatives and skills-based hiring, can tap into a pool of 106 million workers who gained their expertise outside conventional educational paths. Diversifying recruitment strategies is essential to meet the growing demand for specialized roles in defense-tech construction.
The talent shortages in defense-tech construction make it clear: reactive hiring alone won't cut it. Instead, firms need to embrace strategic talent acquisition, planning 12–24 months (or more) into the future. As James Harwood of Soteria HR puts it:
Recruitment is a task; strategic talent acquisition is a system.
This mindset is critical when competing for a small pool of cleared professionals while adhering to strict deadlines and compliance standards. Such a shift often involves working with specialized recruiters to meet the unique demands of defense-tech hiring.
Specialized recruiters play a key role in helping defense-tech companies connect with candidates who already have the necessary security clearances and technical skills. Instead of investing time and resources to develop talent in-house, these services allow you to quickly "acquire" experienced professionals when fast results are essential. For shorter-term needs, contingent or contract arrangements provide access to "niche expertise" on demand.
For example, in early 2025, a federal contractor partnered with CCS Global Tech to fill 10 cybersecurity analyst positions requiring TS/SCI clearances and full-scope polygraphs. While the internal hiring team estimated it would take 6–8 months to fill these roles, the staffing partner delivered 14 fully cleared candidates in under three weeks. All 10 positions were filled within 30 days, saving the client over $1 million in potential delay-related expenses. This success highlights how specialized recruiters maintain a "cleared talent bench" - a pool of pre-vetted professionals ready to step in when needed.
To make these partnerships effective, it's important to set clear expectations. For instance, establish Service Level Agreements (SLAs) with recruiters, like a 48-hour feedback window for resume reviews, to avoid losing candidates to competitors. With an estimated 500,000 to 700,000 open positions for cleared talent across the U.S., speed is a critical factor. Additionally, firms can reduce financial risks by using pay-on-hire pricing models.
Success-based pricing structures minimize upfront costs by charging only when a candidate is successfully placed. This approach is particularly useful in defense-tech, where clearance processing can take anywhere from 6–12 months - and up to 24 months for TS/SCI roles. Instead of paying fees during these long vetting periods, you only pay when the candidate officially starts their role.
For example, iRecruit.co offers flexible pricing options tailored to different hiring needs. If you're filling a single role, there’s no monthly fee - just a 25% success fee based on the first year’s salary (or 3% monthly over 12 months). For two roles, a monthly fee of $8,000 ($4,000 per role) reduces the success fee to 20%. For three or more roles, the fee is $10,500+ ($3,500 per role) with the same 20% success fee.
The best pricing models also account for potential roadblocks. If a candidate’s clearance is denied or a polygraph fails, specialized recruiters can provide pre-vetted alternates ready to step in immediately. This kind of contingency planning ensures projects stay on track and avoids costly delays.
When managing multiple defense-tech projects, Recruitment Process Outsourcing (RPO) offers a scalable solution. RPO providers handle the entire hiring process, allowing firms to meet the demands of several projects at once. The Department of Defense has seen its best results in decades by focusing on workforce professionalization through strategic talent management.
For urgent, high-priority roles, RPO providers can implement "sprint recruiting" models designed to meet tight deadlines. This approach is especially critical when labor shortages and clearance bottlenecks threaten project timelines. Regular evaluations - such as stakeholder interviews and data analysis - can help identify what’s working and replicate those successes across future projects.
For defense-tech firms juggling workforce planning across multiple construction projects, scalable hiring models provide the agility to meet mission-critical demands while ensuring compliance with federal regulations.
Bringing cleared professionals on board is just the beginning; keeping them engaged and committed is where the real challenge lies. Defense-tech professionals thrive on purpose - the chance to tackle complex problems that directly impact national security. When they lack the tools, training, or career direction to make meaningful contributions, they often seek opportunities elsewhere. Retaining this talent requires deliberate action: offering continuous skill development, highlighting the mission-driven nature of the work, and building trust through transparency.
For STEM professionals, staying relevant means updating their skills every 3–5 years. Without regular upskilling, even the best talent risks falling behind. Employers need to invest in ongoing training programs, offer job rotations, and ensure immediate access to the tools and systems employees need to succeed. Delays in providing essential hardware, software, or permissions can frustrate new hires and lead to early departures. A proactive approach to equipping employees from day one can make a significant difference in retention.
STEM professionals... will leave the defense enterprise when they lack purpose, frequently because they do not have the necessary skills, tools, and opportunities to solve tough problems in support of defense missions.

Retention isn’t just about offering competitive salaries - it’s also about showing employees how their work contributes to the bigger picture. Highlighting your organization's role in national security can help employees see the impact of their efforts. Share success stories that connect individual contributions to mission-critical outcomes, and promote technical talent into leadership roles to demonstrate that expertise is valued. Clear career paths are equally important, especially since technical professionals in the federal workforce often face barriers to advancement. In 2019, only 16% of civilian federal positions were classified as STEM, yet these roles frequently lag behind non-technical ones in terms of promotional opportunities.
Trust is the foundation of long-term retention, and it starts well before day one. Defense-tech hiring processes can stretch over eight months due to lengthy security clearance investigations. Keeping candidates informed with regular updates during this period is crucial to maintaining their confidence. Once onboarded, offering guarantees like iRecruit.co's 90-day replacement credit can provide additional peace of mind. This type of commitment reassures both new hires and hiring managers, reducing risk and strengthening trust from the outset. Clear communication and guarantees like these show employees that their value is recognized from the very beginning.
Building a workforce for defense-tech construction projects comes with unique challenges. The combination of a small pool of cleared professionals, strict federal compliance, and fierce competition from commercial tech sectors makes talent acquisition far from straightforward. To make matters worse, the defense industry is losing talent twice as fast as it’s gaining it. This means traditional recruiting methods alone aren’t enough. Success depends on expertise in navigating security clearance requirements and developing long-term talent pipelines.
Consider this: 37% of experts working on Department of Defense-funded projects with advanced STEM degrees are foreign-born. Yet, many of these skilled professionals are ineligible due to clearance restrictions. Meanwhile, China is on track to produce nearly twice as many STEM PhD graduates as the U.S. by 2025. The global race for talent is heating up, and the stakes couldn’t be higher.

Whether you need one key hire or an entire team, the focus must be on building a workforce that’s both qualified and deeply committed to the mission.
Finding cleared professionals for defense-tech roles is no easy task, and several factors contribute to this challenge. For starters, the number of individuals with active security clearances is naturally small because the vetting process is incredibly thorough. It involves detailed background checks that can take months - or even years - to complete.
On top of that, defense-tech roles often require a rare mix of specialized technical expertise and clearance eligibility. This combination makes the hiring process even more restrictive. As the defense industry expands and adapts to new demands, the gap between the need for qualified candidates and the available talent pool becomes even more pronounced.
Federal regulations significantly influence hiring practices in defense-tech projects, primarily through strict compliance standards. For many positions, security clearances are a must, requiring extensive background checks and adherence to government protocols. This not only lengthens the hiring process but also demands specialized screening procedures.
Regulatory frameworks like the Defense Federal Acquisition Regulation Supplement (DFARS) and cybersecurity requirements further shape recruitment strategies. Companies must focus on finding candidates with the necessary technical skills and clearance levels - or those willing to undergo the clearance process. These rules also highlight the importance of strong training programs and workforce development efforts to keep up with changing standards. The ultimate goal of these federal requirements is to build defense-tech teams that are skilled, secure, and ready to handle critical missions.
Defense-tech companies can hold onto top talent by prioritizing career growth, attractive benefits, and a supportive work environment. Providing employees with clear advancement paths - like access to specialized training programs or certifications - not only keeps them engaged but also shows they’re valued.
Competitive pay and benefits tailored to the unique demands of the defense-tech sector are also essential. Beyond that, fostering a workplace where employees feel included and supported makes a huge difference. Recognizing achievements, encouraging teamwork, and connecting employees to meaningful, mission-driven projects can significantly improve retention.
Lastly, keeping up with industry changes and offering continuous professional development ensures employees stay motivated and ready to handle new challenges.
