Keller Executive Search is a headhunting and talent acquisition firm that helps companies and organizations in the industry source, vet, and attract high-caliber talent to fill open leadership positions. Our team of defense recruiters has extensive experience in conducting searches across primes, mid-tier suppliers, and private equity-backed platforms. This knowledge allows us to surface skilled professionals and senior leaders who understand the realities of the industry.
The Defense Executive Talent Market
The U.S. defense executive talent market includes a $890.6B national defense budget and a 2.1M aerospace and defense workforce. In 2025, the industry generated nearly $1 trillion in total sales and a $73.9 billion trade surplus, exporting $138.6 billion in technology to allies and partners. The sector is supported by MIT Lincoln Laboratory, the Johns Hopkins Applied Physics Laboratory, and the Georgia Tech Research Institute, among the nation’s most respected defense research institutions.
Big names in the industry include Lockheed Martin, RTX, General Dynamics, Boeing, Northrop Grumman, Leidos, and L3Harris. These employers operate in the aeronautics, space, land and sea systems, cyber, and defense services industries. There’s a high demand for engineering and technical leadership, and 76 percent of Aerospace Industries Association member organizations are reporting ongoing difficulties in hiring engineering talent.
The constraint is competition for this talent, not the supply of open roles. Industry-wide attrition has been hovering around 15 percent, which AIA and McKinsey say is more than twice the average across other U.S. industries. Now, a maturing defense technology sector hires cleared engineering and program leadership directly against established primes. The same dynamic drives retention pressure at the executive level.
Our defense recruiters connect companies in the defense and aerospace community to talented and effective leaders across the globe. Our mission is to help clients usher in transformational change by filling leadership and C-suite positions with the most qualified candidates. We achieve this through:

Our assessment and evaluation process is extensive and involves screening each leadership talent based on their education, skills, and track record, as well as general and criminal background checks. Our specialists also take into consideration other factors in the initial evaluation, including a candidate’s personality, work ethic, management style, and cultural alignment.

Keller Executive Search provides defense companies with a diverse pool of candidates, thanks in part to our extensive industry connections. We leverage our network for referrals and recommendations on exceptional talent who may fit our client’s recruiting needs.
Additionally, we also post queries across social platforms and make hundreds of cold calls and emails to reach qualified candidates who are either actively or passively looking for new job opportunities.

Beyond defense executive search, our team also offers guidance to clients on optimizing HR processes, employee engagement, and retention. We are able to achieve this due to our team’s experience and in-depth knowledge about the sector, having previously worked in companies across a number of aerospace and defense industries.

Our approach to every engagement is unique. We tailor our search based on the recruiting needs of our clients, the organization’s culture, and what constitutes success in the defense industry. Our method ensures clients are only supplied with talents with the skillsets needed to thrive in the position.
To achieve that goal, each engagement begins with an introductory meeting. Our defense recruiters work with the clients to define what the role covers, which programs it supports, who it reports to, and what it needs to achieve. This is especially important since defense roles come with requirements that other searches do not have, such as clearance status, export control experience, and the ability to work under public scrutiny.
We then use this information to build a profile that serves as our guide when we begin mapping the market. We use a combination of traditional methods and our network of defense talents to surface candidates who match the brief. We look across the industry, including defense, aerospace, and private equity portfolio companies, for high-impact executives. Our vast network also allows us to reach even passive candidates who are not looking for a new role and would otherwise be impossible to find.
Each candidate goes through an extensive assessment that covers and confirms their technical background, program experience, proven track record, and clearance status. We also verify credentials and check references with people who have worked with the candidate directly. All findings are documented and presented to the client before the final interviews are conducted for shortlisted talents.
When we first started as a defense executive search firm, we filled senior-level roles using a generic process that ignored important factors such as cultural fit, management style, work ethic, and team chemistry. This resulted in a situation where some of the placements we made failed to meet client expectations, or the candidates could not thrive in the work culture.
Due to these shortcomings, we stepped back and developed a more targeted approach. The process now considers intricate factors that affect the outcome and takes into account industry-specific challenges. This has led us to continually locate and place high-caliber leaders in critical posts.

Our defense executive search team has vast experience in recruiting high-impact executives. We have filled roles across a full range of defense programs, including but not limited to:

At Keller Executive Search, we routinely deliver candidates from C-suite roles such as chief operating officer or chief executive officer, to senior general managers, to management talents, as well as heads of engineering, R&D, business development, government relations, supply-chain logistics, quality, training and simulation, and every role in the aerospace & defense industry.
Because we have former aerospace engineers, program managers, and human resources chiefs on the search team, we understand the nuanced demands of businesses in the sector. That expertise lets us engage passive, top talent for roles ranging from R&D and advanced manufacturing leadership to finance, supply chain, and government relations executives who navigate ITAR, FAR, and offset agreements with equal fluency. We fill senior program and P&L owners who can integrate AI-driven production lines, cybersecurity stewards who harden C5ISR platforms, and business-development visionaries who open new markets in space, land, sea, air, and cyber domains.
Each search begins with us mapping the strategic outcomes you need to achieve. We also tailor our process to fit the goals and needs of our partner organizations, allowing us to provide clients with access to the precise executive, technical, or program leadership their business demands.

Beyond our recruitment process, we advocate for fair and respectful hiring practices. We also value continual education, investing resources to stay current on industry trends and technological advancements.

Keller upholds the highest standards of professionalism and confidentiality throughout the search process. All information given to us by our clients is handled with discretion. We will never compromise the safety of our business partners at any stage of the search.

Selection followed the refined brief, and the top candidate accepted soon after receiving the final terms. The onboarding process proceeded as scheduled, with no further pre-employment verification being requested. Keller Executive Search identified a manufacturing accountant whose experience matched the current operating needs of the team. Stronger day-to-day oversight can now coexist with a longer-term plan for continuity in finance leadership. Succession is still possible, but credibility will first have to be built through detailed accounting, ownership, and consistent support for factory operations.

An offer was made and, after the candidate had some time to review it, the letter was returned signed. Pre-employment background and drug screening were conducted before the appointment was confirmed, as well as credit and education verification. Keller Executive Search placed the company’s first General Manager, who now provides the plant with unified leadership over its five reporting managers for the first time.

An offer was made and accepted, background checks were done, and placement confirmed. The organization hired a full-time administrative professional with the financial, HR, and operational experience the new position required.
