How to Hire a VP of Engineering for a Defense Tech Startup

A defense tech founder just closed their Series A. Money in the bank, product-market fit validated, first contracts with defense customers signed. The next step is obvious: hire a VP of Engineering to build out the engineering team and turn a prototype into a production-ready product. This is where the most expensive mistake in the life of a young MilTech company begins. In the experience of IT recruitment agency EvoTalents, which specialises in defense tech, cybersecurity and AI/ML verticals, most founders approach this hire with a fundamentally flawed frame: they search for a "cleared defense engineer who can manage" instead of "an engineering leader who can build a team in a defense context." The difference between these two framings costs 6-12 months of lost time and hundreds of thousands of dollars.

1. THE SECURITY CLEARANCE TRAP: WHY FOUNDERS OVERVALUE CLEARANCES

The first and most common mistake is turning security clearance into a hard filter for the VP of Engineering position. The founder's logic looks rational: "we work with classified data, we need someone with clearance." In practice, this filter creates a catastrophic narrowing of the candidate pool and shifts it towards people whose main advantage is time served in the cleared world, not leadership qualities.

Clearance can be sponsored, leadership cannot

In both the US (Secret/TS/SCI) and the UK (SC/DV), an employer can sponsor a candidate's clearance. Yes, it takes time: UK DV vetting can take a significant period, and American checks have their own timelines. But the key insight is that clearance is a gate, not a competency. Clearance can be obtained after joining. The ability to build teams from scratch, establish delivery cadence and recruit senior engineers in a competitive market cannot be developed in 6-12 months.

The right approach: clearance should be "nice to have, sponsor if missing" for leadership roles. A hard clearance requirement on day one is justified only for a narrow set of IC positions where the specialist must touch classified materials immediately. For a VP of Engineering, this is almost never the case.

2. THE BIG PRIME SYNDROME: WHY LOCKHEED/BAE/RAYTHEON EXPERIENCE OFTEN HURTS

The second most common mistake is reflexively hiring "the VP of Engineering from Lockheed Martin / BAE Systems / RTX / Leonardo / Northrop Grumman." The founder's intuition is understandable: these people know defense. The problem is they know the wrong kind of defense.

Engineering leadership at major prime contractors is optimised for the reality of multi-year cost-plus contracts, waterfall programme management and compliance-first culture. These instincts actively work against the iterative, product-led model that modern defense tech startups are trying to build, and that their government customers increasingly demand.

The typical failure mode

A leader from a prime arrives and starts building process before the product exists. They cannot recruit startup-calibre engineers because they are used to a different type of candidate. They are uncomfortable with the "demo, iterate, redeploy" cadence that increasingly wins modern defense contracts. The result: the company slows down precisely when it needs to accelerate.

This does not mean prime experience has no value. Navigating procurement, accreditation, understanding customer requirements: all of this is critically important domain input. But it should be exactly that: input (through an advisory role or a separate VP of Programs/Compliance position), not the core of the first engineering leadership hire.

3. THE IC-VP CONFUSION: BEST ENGINEER ≠ BEST LEADER

Founders regularly promote or hire a brilliant individual contributor into a VP role, confusing deep technical talent with leadership capability. This is one of the most destructive mistakes in the early stages of a company.

A VP of Engineering is a force multiplier. Their output is the team's output. The key deliverables of the position: hiring people, designing the organisation, establishing delivery cadence, managing stakeholders. Not personally writing the hardest code.

How to spot the problem in an interview

Ask the candidate about people they have hired, developed and let go. About organisational structures they have designed. About how they established delivery cadence. If the candidate's strongest stories sound like "here is the complex system I built," that signals the wrong level. A VP candidate should talk about teams they created and the results those teams achieved.

The worst-case scenario: the company loses an excellent IC and gets a VP who cannot cope. If your strongest engineer is a brilliant builder, keep them as a builder and search for the VP separately.

4. DUAL-USE AS A DISTINCT LEADERSHIP COMPETENCY

Most modern defense tech startups build dual-use technologies sold to both commercial and government customers. This creates a unique requirement for the VP of Engineering: the ability to hold two operating modes simultaneously.

The first mode is commercial speed: rapid iteration, CI/CD, weekly releases, product-led development. The second mode is defense-grade security: accreditation, supply chain security, access control, government procurement cycles that stretch over months.

Why this is a rare profile

A VP Eng who has spent their career shipping SaaS products will underestimate the complexity of accreditation and government procurement cycles. A VP Eng who has spent their career in classified environments will over-engineer process and kill velocity. The rare and valuable profile is someone who has lived on both sides. These are the candidates to target first, and dual-use experience is precisely what most founders forget to screen for in interviews.

5. RECRUITING AS THE VP OF ENGINEERING'S NUMBER ONE SKILL

In a market where every defense tech company is fishing in the same small pond, the VP Eng's ability to attract and close senior engineers is arguably their most valuable skill. And it is a criterion that founders consistently undervalue.

At EvoTalents we see this constantly: a technically impeccable VP takes the role and cannot build the team. They do not know how to "sell" the mission to candidates. They have no network to pull people from. They do not understand how to close senior engineers who have 5-7 offers at the same time.

How to test this skill

Make recruiting ability the first item on your interview scorecard. Ask: "Tell me about the three strongest engineers you have hired. How did you find them? Why did they choose you over a competitor?" Verify through reference checks: speak to people the candidate has hired and to those who worked with them. If a candidate cannot convincingly describe their recruiting track record, they are not ready to be VP Eng at a defense tech startup.

6. COMPENSATION AND MISSION: BETWEEN TWO WORLDS

Defense tech comp sits awkwardly between two worlds. Leaders from traditional primes are used to lower cash but stable, pension-backed packages. Commercial tech leaders expect high cash plus meaningful equity. A startup that tries to hire a commercial-calibre leader on prime-style cash loses them. A startup offering an equity-heavy package to a prime leader finds the equity story does not resonate.

What works

The winning compensation structure leads with mission and meaningful equity while being honest that cash may trail pure commercial tech. The mission-driven narrative, sovereign capability, deterrence, supporting allies, is the defense tech recruiter's strongest tool, closing candidates where cash alone cannot.

Practical benchmarks: VP Engineering packages at well-funded US defense tech startups include substantial cash plus equity and exceed prime contractor levels. In the UK, engineering leadership cash sits noticeably below US levels, reinforcing the need to compete on equity and mission rather than cash parity.

7. UK SPECIFICS: SC/DV, AUKUS AND A THIN CANDIDATE POOL

The UK MilTech ecosystem has matured rapidly, anchored by Helsing (UK presence), Improbable Defence, Hadean and Faculty AI. Government infrastructure, the Defence and Security Accelerator (DASA), the National Security Strategic Investment Fund (NSSIF), the 2025 Strategic Defence Review and rising defense budgets, is pulling increasing capital and talent into the sector.

Three UK-specific constraints

First: SC/DV vetting timelines and a thin pool of cleared leaders. UK Security Check (SC) and especially Developed Vetting (DV) require significant time. The pool of engineering leaders who are both commercially excellent and already DV-cleared is extremely small. This makes the "already cleared" hard filter even more damaging in the UK than in the US.

Second: AUKUS and talent mobility. AUKUS Pillar 2 (advanced capabilities) and the 2024 reforms easing defense trade between the US, UK and Australia (including ITAR-exemption arrangements) are increasing both collaboration and competition for cleared dual-use engineering talent across the three countries.

Third: the UK vs US gap. The US market has deeper defense tech capital, larger equity packages and a broader pool of "commercial leader who has also done defense" candidates. The UK has a stronger mission/sovereignty narrative in the wake of the war in Ukraine and a tighter-knit ecosystem, but shallower compensation packages and a narrower cleared-leader pool. This is precisely why UK founders must compete on mission and equity and plan clearance sponsorship from day one.

8. TIMING: WHEN TO HIRE THE VP OF ENGINEERING

Another classic mistake is getting the timing wrong. There are two failure modes, and both are expensive.

Too early: the founder hires a VP Eng before there is a team to manage or a clear product-market signal. A senior hire spends their time on IC work, cash burns, the VP is frustrated by the lack of scale.

Too late: the team has grown to 10-15+ engineers without formal leadership. Organisational debt accumulates and is painful to unwind. Processes are absent, technical debt has piled up, culture has formed organically.

The optimal window

The typically right moment is the Series A / early Series B inflection point, when the team is scaling beyond what founders can manage directly. The VP Eng should arrive with a clear mandate: build the team and the delivery machine. If clearance is needed, sponsorship begins on day one, in parallel with core responsibilities.

9. THE HYBRID PROFILE: WHAT THE RIGHT CANDIDATE LOOKS LIKE

The empirical signal from the market is clear: companies that "got it right," Anduril, Palantir, SpaceX, Shield AI, Helsing, almost universally filled senior engineering leadership from commercial high-performance backgrounds and layered defense domain knowledge on top. Not the other way around.

The target profile

This is a commercial tech engineering leader with real experience in mission software or government exposure. The archetype: ex-Palantir, ex-Anduril, ex-SpaceX, ex-Shield AI, ex-Helsing. Or a commercial leader who has shipped in regulated/critical infrastructure environments (heavily regulated fintech, healthcare with compliance, energy with safety requirements). They bring modern engineering practice and credibility with defense buyers at the same time.

If finding a single hybrid candidate proves impossible, an alternative model works: a strong commercial VP Eng plus a cleared/domain deputy. This is better than compromising on leadership quality for the sake of clearance or domain pedigree.

EVOTALENTS CASE STUDY: WHAT BUILDING AN ENGINEERING TEAM IN DEFENSE TECH ACTUALLY LOOKS LIKE

The primary reason a defense tech startup needs a strong VP of Engineering is to scale the engineering team. Here is an example from EvoTalents' practice that shows the kind of challenge a VP Eng will face in their first months on the job.

Client: a company developing autonomous drone and UAV systems for defense and aerospace applications.

The challenge

The company needed to fill three engineering roles simultaneously: a Matlab Engineer (simulation and modelling), a System Engineer Lead (drone systems architecture) and an Aerospace Systems Engineer (flight systems). Each role required a rare combination: deep aerospace knowledge, defense domain experience and hands-on proficiency with specific tools, Matlab/Simulink, systems engineering methodologies, flight control systems.

This is exactly the type of challenge that falls on the shoulders of a VP of Engineering: filling multiple highly specialised roles in parallel in a market where candidates with the required intersection of skills are few and far between.

EvoTalents' approach

• Deep mapping of the aerospace and defense engineering talent pool
• Targeting candidates simultaneously from three sources: defense contractors, aerospace R&D institutes and drone startups
• Sourcing passive candidates from academic research labs and military-adjacent engineering communities
• Running all three searches in parallel to match the aggressive team-building timeline

Result

All three positions filled: Matlab Engineer, System Engineer Lead, Aerospace Systems Engineer. Searches ran in parallel, with candidates coming from different market segments.

Why this matters for the VP Eng hire

This case illustrates the reality any VP of Engineering in defense tech will face: narrow candidate pools, the need for non-standard sourcing channels (academia, R&D, military-adjacent communities) and the necessity of running multiple complex searches simultaneously. A VP Eng who came from a big prime or pure SaaS and is used to a different kind of market will not be able to build such a team effectively. A hybrid leader who understands both defense domain and modern sourcing approaches will do it significantly faster.

THE MOST COMMON MISTAKES: A FOUNDER'S CHECKLIST

Let us summarise the mistakes we see most often, in order of the damage they cause:

• Clearance as a hard filter: narrows the pool and shifts it towards people whose main asset is time in the cleared world, not leadership. Sponsor the clearance, search for leadership.
• Hiring from a prime by default: prime contractor pedigree is optimised for cost-plus and compliance-first culture, the opposite of what a startup needs.
• IC instead of VP: the best engineer is rarely the best VP. A force multiplier and a hands-on builder are different roles.
• Ignoring dual-use: the ability to hold two operating modes simultaneously is a separate competency that must be screened for.
• Recruiting ability not a priority: in a tight market the VP Eng's ability to attract and close engineers matters more than their technical depth.
• Compensation mismatch: neither prime-style cash for a commercial leader nor equity-heavy packages for a prime leader work. Lead with mission.
• Wrong timing: too early means the VP does IC work and cash burns; too late means organisational debt.
• Culture clash: startup speed and the defense compliance mindset are in genuine tension. This is a leadership temperament question, not a resume question.

FAQ

Does a VP of Engineering at a defense tech startup need security clearance?

In most cases, no, not from day one. Clearance can be sponsored after joining. A hard clearance filter critically narrows the candidate pool and shifts it towards people with prime contractor backgrounds who often lack startup leadership skills. Clearance as a hard requirement is justified only for roles where the specialist must touch classified materials immediately.

Where should you hire a VP of Engineering for a defense tech startup?

The strongest signal from the market: look for commercial tech engineering leaders with mission software or government exposure. Candidates with backgrounds at ex-Palantir, ex-Anduril, ex-SpaceX, ex-Helsing or from regulated/critical infrastructure environments (fintech, healthcare) bring both modern engineering practice and credibility with defense buyers.

When is the right time to hire a VP of Engineering at a MilTech company?

The optimal window is the Series A / early Series B inflection point, when the engineering team is scaling beyond 8-12 people and founders can no longer manage it directly. Too early means the VP does IC work and cash burns. Too late means organisational debt that is painful to unwind.

How long does it take to find a VP of Engineering in defense tech?

Senior leadership roles in defense tech are among the slowest to fill. A narrow candidate pool, intense competition and the need for clearance vetting mean the realistic timeline for a VP of Engineering search is 3 to 6+ months. Adding SC/DV vetting in the UK can extend the total time from search start to full onboarding significantly. If the search exceeds 4-6 months without a result, it is worth engaging a specialist recruiter.

How can you compete for a VP of Engineering against better-funded US defense tech startups?

For UK MilTech companies: lead with mission narrative and meaningful equity rather than trying to match US cash. The UK has a stronger sovereignty narrative in the wake of the war in Ukraine and a tighter-knit ecosystem. Plan clearance sponsorship from day one and be transparent about the compensation gap.
