Most defense tech companies start with contingency recruiting because it feels safe.
No upfront cost. No commitment. You pay only when someone gets hired.
That logic collapses the moment you understand how contingency actually works from the recruiter's side.
What Contingency Recruiting Actually Is
In a contingency arrangement, the recruiting agency is not paid until they place a candidate. No placement, no fee.
This sounds like a low-risk setup for the company. It is not.
It is a high-risk setup that transfers the financial pressure entirely onto the recruiter and then lets that pressure shape every decision they make on your search.
A contingency recruiter is typically working 10 to 20 searches at the same time. They cannot afford to invest deeply in any one of them. Their math requires volume. They prioritize the searches most likely to close quickly, submit candidates across multiple clients simultaneously, and move on when a search gets complicated.
Defense tech searches get complicated. That is not a flaw in the talent market. It is the nature of the roles.
Why Defense Tech Searches Break the Contingency Model
The contingency model was designed for high-volume, low-complexity hiring. It works for roles where the candidate pool is large, the requirements are standard, and the timeline is predictable.
Defense tech hiring is the opposite of all three.
Candidate pools are narrow. Clearance requirements filter out the majority of technically qualified engineers before the first conversation. Finding a cleared software engineer with radar systems experience and startup tolerance is not a Google search. It is a months-long sourcing effort.
Requirements are non-standard. A hiring manager who can specify exactly what "cleared, dual-use embedded systems engineer with CCA program familiarity" means is describing a person who does not appear on job boards. They have to be found. That takes time a contingency recruiter is not being paid to spend.
Timelines are not predictable. DCSA's current 90th-percentile processing time for a Top Secret clearance is 227 days, and that is the optimistic number. A contingency recruiter factoring real clearance timelines into their math will deprioritize your search in favor of clients who can close in 30 days.
The result is predictable. You get a burst of resumes in week one. Most do not fit. The recruiter goes quiet. Three months later you have no hire and no progress.
The Incentive Problem That Nobody Talks About
The deeper issue with contingency is not the timeline. It is the misalignment built into the model.
A contingency recruiter earns money by placing a candidate. Not by finding the right candidate. Not by protecting you from a bad hire. By closing the search.
Those incentives produce specific behaviors. The recruiter manages your expectations down on compensation if they think a lower offer will close faster. They push you toward an offer before diligence is complete. They present candidates they believe you will hire, not candidates who are the best fit.
None of this is dishonest. It is rational. The financial structure of the relationship produces it.
Retained and embedded recruiting fix the incentive at the source. When the fee is not contingent on a single placement closing, the recruiter can tell you the candidate pool is thinner than you expected, advise you to pass on a good-but-not-right candidate, and take the time the search actually requires.
The Three Models, Explained Honestly
Contingency Recruiting
You pay only when you hire. Typically 20 to 25 percent of first-year salary.
The recruiter is not exclusively working your search. They are running your search alongside many others, submitting candidates to multiple clients, and competing with other firms who may also be working your roles.
Good for: high-volume hiring, entry-level or mid-level roles, markets with abundant candidates, companies that need to test the water before committing to a recruiting partner.
Not built for: defense tech, cleared technical roles, senior IC or leadership hiring, searches where a mis-hire would cost more than the fee.
The risk you do not see: your confidential job requirements circulate through a recruiter who is also working your competitors. You are not their only client, and neither are you.
Retained Search
You pay an upfront retainer, typically split across three milestones: kickoff, candidate slate delivery, and placement. The fee covers the recruiter's full attention to your search on an exclusive basis.
Good for: executive searches, highly confidential placements, roles where the cost of a mis-hire is significant, companies that need one specific person found.
The advantage is alignment. A retained firm has been paid to work your search. They are not choosing between your search and a faster one. They have committed resources to your role.
The limitation is scope. Retained search is built for episodic, high-stakes placements. It is not a scalable model for companies hiring eight engineers across 18 months. For a detailed breakdown of what embedded recruiting costs vs retained search, the numbers tell the story clearly.
Embedded Recruiting
A senior recruiter integrates directly into your company for a defined engagement period. They learn your business, your technical requirements, your compensation philosophy, your team structure. They source, screen, coordinate, and close as a member of your team.
You pay a monthly engagement fee. There is no per-placement commission. There is no conflict between your search and another client.
Good for: defense tech companies in a sustained hiring phase, Series A through Series C companies building recruiting infrastructure without the overhead of a full in-house team, founders who need a partner who understands what they are building.
The advantage is what happens after month one. An embedded recruiter who has learned your company stops asking basic questions and starts anticipating them. They know which candidate profiles will get through your technical screen. They know your offer ceiling. They know the compensation objections they will hear. By the time they close your first hire, they are already sourcing for the next one.
What a Mis-Hire Actually Costs
The upfront cost of retained or embedded recruiting is the number that feels real. The cost of contingency recruiting is harder to see until after it lands.
A mis-hire at the senior IC or engineering manager level costs between 50 and 200 percent of that person's annual salary in lost productivity, re-onboarding, and recruiting again. A three-month search that produces no hire costs three months of headcount gap on a team that is already stretched. A candidate submitted to your competitors before your diligence closes is a risk you never knew you took.
Contingency recruiting externalizes those risks onto your company. The recruiter absorbs none of them. They move on to the next search.
What to Look for in a Recruiting Partner
Whether you choose retained or embedded, the criteria for evaluating a defense tech recruiting partner are the same.
They should understand the market specifically. Not just recruiting in general. Defense tech, cleared talent, dual-use deep tech. Ask them what TS/SCI processing looks like in 2026. Ask how they source cleared software engineers who are not actively looking. If they cannot answer both without hesitating, they are not built for this.
They should tell you the truth before the search starts. A real recruiting partner will tell you if your compensation is below market, if your location creates a candidate headwind, or if your clearance requirement adds six months to the timeline. That conversation is uncomfortable. It is also the one that saves you from a four-month search that ends with no hire.
They should have a defined process. Sourcing strategy, screening criteria, interview coordination, offer stage guidance. If they cannot walk you through it in ten minutes, they are improvising.
ALAC's Model
ALAC runs embedded and retained search for defense tech and deep tech companies at Series A through Series C.
Our average fill time is 45 days. That number exists because of the model. We are not splitting attention across a portfolio of contingency searches. We are inside your hiring process, learning it, running it alongside you.
The 45-day average is a structural outcome of working this way. Not a marketing claim.
If you are in an active hiring phase or projecting headcount growth in the next 90 days, the right time to talk to a recruiting partner is before you post the first job description.
Frequently Asked Questions
What is the difference between contingency and retained recruiting?
Contingency recruiters are paid only when a placement closes. Retained recruiters receive an upfront fee and are exclusively committed to your search. The difference is not just financial. It changes who has leverage in the relationship and how the recruiter prioritizes your search.
Is contingency recruiting ever the right choice for defense tech?
It can work for entry-level or mid-level roles with standard requirements and large candidate pools. It is rarely the right choice for senior technical hires, cleared roles, or searches that require deep sourcing.
What does embedded recruiting cost?
Embedded recruiting is priced as a monthly engagement fee rather than a per-placement commission. The total cost for a six-month engagement covering multiple hires is typically lower than the equivalent contingency fees, and it comes without the hidden costs of a prolonged search.
How is embedded recruiting different from retained search?
Retained search is built for a single executive or leadership placement. Embedded recruiting is built for companies in a sustained hiring phase who need recruiting infrastructure over time, not a one-time search.
What should I ask a defense tech recruiting agency before engaging them?
Ask about their average fill time, their sourcing process for cleared engineers, how they handle candidate confidentiality, and whether they have placed roles with similar requirements before. The answers will tell you more than their website does.
