Hiring a business developer in defence: portfolio is the wrong criterion
The 27 EU member states spent €115 billion on defence equipment in 2025, up 26% on 2024, according to the European Defence Agency's Defence Data 2025-2026 report. The money is there, the orders are there.
What's missing are the teams to win them.
Since the start of 2026, we've never had so many requests for sales roles in defence: Business Developer, Head of Sales, Sales Director, Key Account Manager. Companies that weren't in this market 18 months ago now want to open a vertical.
And when a company calls us to hire a business developer in defence, the brief almost always comes in the same shape.
It fits in one sentence: a salesperson with an existing defence portfolio.
We start from there too. Except that pool is tiny, and everyone is fighting over the same people.
Key takeaways
- An existing defence portfolio is the most requested criterion and the least available one. Insist on it and you're competing with every one of your rivals for a handful of profiles, at the same time.
- What you're actually looking for behind the portfolio is understanding of a long sales cycle, the ability to read a procurement ecosystem, and command of the vocabulary. All three are acquired elsewhere.
- 3 alternative profiles work: ex-military personnel moving into civilian sales, reservists with a civilian sales career, and engineers who moved into technical sales.
- The pool exists: Défense Mobilité supports more than 14,000 service members back into civilian life every year, and the operational reserve numbered around 48,600 volunteers as of 31 October 2025, with a target of 105,000 by 2035.
- Across our own defence sales placements, not one hire arrived with an existing defence portfolio.
- A sales role exposed to classified information requires security clearance, which needs to be planned for from the brief stage and shapes the hiring timeline.
Why is everyone chasing the same salesperson?
The logic behind the brief is always the same. You're selling into a closed market, structured around a handful of prime contractors, France's Direction générale de l'armement (the defence procurement agency), and a small group of main contractors. A salesperson already known to them saves months.
The problem is that every company applies the same logic at the same time.
Europe's defence sector is made up overwhelmingly of SMEs and mid-sized firms, and the wave of new entrants seen since 2024 has multiplied job openings without adding a single experienced salesperson to this market. You're not hunting in a narrow pool. You're hunting in the same narrow pool as your direct competitor, with the same pitch.
The result: roles that stay open for 6 months, counter-offers that spiral, and hires that fail on a profile that had, in any case, never built a vertical from scratch.
What does a "defence portfolio" actually cover?
When we dig into the brief with hiring teams, the portfolio almost always breaks down into 4 distinct skills.
- Reading the ecosystem. Knowing who decides, who recommends, who influences, and where your company sits in the chain between a prime contractor and a tier-3 subcontractor.
- The long cycle. A defence sales cycle runs in quarters, sometimes years, shaped by public tenders, budget milestones and political arbitration. A salesperson used to short cycles burns out on it.
- The vocabulary. Not jargon for its own sake: the ability to hold a technical conversation with a programme officer without needing things repeated three times.
- The address book itself, the only one of the four that doesn't transfer cleanly from one company to another. A relationship built at one integrator doesn't automatically reactivate from a new role.
In other words, the least transferable skill is the one briefs place as the top criterion. The other three are acquired on paths nobody looks at.
Which profiles actually work for hiring a business developer in defence?
Working with the companies we support right now, we've converged on 3 families of profiles. All of them have been tested on roles that were actually filled.
Ex-military personnel moving into civilian sales
They know the inside codes: the decision chain, operational constraints, how a capability requirement gets expressed and then funded. What they need to learn is sales itself. Which can be taught.
The flow exists and it's documented. Défense Mobilité, the French Ministry of the Armed Forces' career-transition service, supports more than 14,000 service members back into civilian life every year. A share of them explicitly target sales and business-development roles.
The question to ask in interview isn't "do you know the sector", it's: have you already owned a numerical target and been measured against it.
Reservists with a parallel civilian sales career
This is the most underrated profile on the market. An operational reservist holds a full civilian job, often outside defence, while keeping an active military footing.
You get both halves: a salesperson trained in the civilian world, used to long cycles and end-to-end project management, and someone who doesn't need the organisation of the armed forces explained to them.
The pool is growing fast. The operational reserve numbered around 48,600 volunteers as of 31 October 2025, according to the deputy chief of staff for human resources' hearing before the National Assembly's defence committee on 3 December 2025. France's 2024-2030 Military Programming Law sets a target of 80,000 by 2030, then 105,000 by 2035.
Engineers who moved into technical sales
They don't have the address book. They have something else: they speak the client's language.
In a sector where the person across the table is a systems engineer, a programme officer or a design-office manager, that's often what tips a deal. A salesperson who understands why a certification constraint shifts a milestone by 8 months doesn't lose credibility at the first technical question.
It's also the easiest profile to identify, because it's often already inside your own walls or at your suppliers.
"The defence business has become technical. You no longer sell a system with a nice presentation. The salespeople in this sector have a level of technical expertise I don't find anywhere else."

What our own placements show
We're not asking you to take our word for it. Here's what our defence sales hires actually look like.
For Cegelec Défense (VINCI Energies Group), we filled 2 successive sales roles: a Sales Director, then a Defence & Security Key Account Manager. Both are security-cleared roles, covering a scope from industrial manufacturers to ministries and the armed forces.
Neither hire arrived with a defence portfolio. The first had run sales for an industrial SME in the same region. The second came from a generalist digital services company. What they had in common: a mastered long sales cycle, an industrial culture, and the ability to build a pipeline from zero.
We also filled a Head of Sales role for Arkane Cloud, on the sovereignty scope, and a business developer and strategic partnerships role for a European start-up reindustrialising parts production for aerospace and defence.
Across all of these hires, an existing portfolio was never the deciding criterion. It wasn't available with any of the candidates we selected, either.
What to put in the brief instead of the portfolio
4 criteria, to be weighed in this order.
- The cycle length already handled. Ask for the real average duration of closed deals, not the sector.
- The ability to build a pipeline from nothing. A salesperson who has always inherited a portfolio hasn't proven this skill.
- Technical comfort level. Bring an engineer into the interview process, not just sales leadership.
- Clearability. This is an administrative criterion, not a sales one, and it's handled separately.
This last point deserves close attention. A sales role exposed to classified information requires national defence secret clearance, requested by the employer and granted after an administrative investigation. It needs to be planned for from the brief stage and shapes the start-date timeline. We detailed the full mechanics in our article on hiring a defence engineer and security clearance, whose rules apply the same way to sales roles.
In summary
The defence market is growing faster than its sales talent pool. Insisting on an existing portfolio means competing for a few dozen people, against every one of your rivals, on a criterion that transfers poorly.
Military career paths, the operational reserve and technical sales open up 3 much broader pools, provided you rewrite the brief around what you're actually looking for.

FAQ
Should you require an existing defence client portfolio to hire a salesperson?
No, and it's often counter-productive. The address book is the only skill in a "defence portfolio" that doesn't transfer cleanly from one company to another, whereas reading the ecosystem, mastering the long cycle and technical vocabulary are acquired on other paths. Requiring this criterion puts you in direct competition with every other recruiter in the sector for a pool of a few dozen people.
Can a former service member become a business developer in defence?
Yes, and it's one of the 3 alternative profiles that work best. They know the decision chain, operational constraints and the vocabulary from the inside. What they need to learn is sales itself. In interview, check that they've already owned a numerical target and been measured against it. Défense Mobilité, the French Ministry of the Armed Forces' career-transition service, supports more than 14,000 service members into civilian life every year.
Do you need security clearance for a sales role in defence?
It depends on the role's actual exposure. Clearance is required as soon as the person accesses classified information, which happens frequently in business-development roles tied to programmes. It is requested by the employer, via their security officer, and granted after an administrative investigation. Qualify the requirement before launching the search, not after identifying a candidate.
How much does a business developer in defence earn?
Across the 69 permanent placements in our 2026 tech and engineering salary barometer, the Sales and Business family comes out at a median gross annual salary of €56,000, and roles with clients in aerospace, defence and industry at €64,000. These figures are based on a small sample and are not a market benchmark. Sales leadership roles sit well above that.
Is an operational reservist a good sales profile for defence?
It's the most underrated profile on the market. A reservist holds a full-time civilian job, often outside defence, while keeping an active military footing. You get a salesperson trained in the civilian world and someone who understands how the armed forces are organised. The pool is growing fast: around 48,600 volunteers as of 31 October 2025, against a target of 105,000 by 2035 set by France's 2024-2030 Military Programming Law.
Where do you find salespeople for a defence vertical that's just starting out?
Not on job boards. The profiles capable of launching a vertical from scratch are already employed and aren't applying. Direct approach is the only realistic route, and it means mapping 3 pools in parallel: ex-military personnel in transition, reservists with a sales career, and engineers who moved into technical sales at your suppliers or partners.
How long does it take to hire a salesperson in defence?
At Bluecoders, the median time-to-deal is 22 days between a role opening and an accepted offer, according to our 2026 data across all hires. Leadership and security-cleared roles take longer. On a cleared role, the actual start date then depends on the administrative investigation, whose timeline isn't within the employer's control.
Should you hire an engineer or a salesperson to sell in defence?
Both work, but not for the same role. An engineer who moved into technical sales is formidable in pre-sales and on cycles where technical credibility decides, less comfortable building a pipeline. An established salesperson does the reverse. On a vertical that's just starting, building the pipeline comes first, provided a technical lead is paired into the sales process.
