The Hiring Problem Nobody Warns Space and Deep Tech Startup Founders About

You raised the round. You have the roadmap. You know exactly what needs to be built. But the engineers who can build it are not answering your LinkedIn messages.

This is the reality for most founders running space and deep tech startups between Seed and Series C. Satellite communications, Earth observation, propulsion, space hardware. The technology is cutting-edge, the mission is compelling, and the talent pool is painfully small. The people you need are either locked inside SpaceX, absorbed by Amazon's Project Kuiper, or sitting behind a security clearance at a defence prime that pays 30% more than you can afford.

I have spent over two decades helping companies in this exact position. From pre-revenue startups with just a handful of engineers to organisations scaling beyond 2,000 employees, I’ve worked across every stage of growth. I’ve also partnered with leading space agencies and institutions including European Space Agency, EUMETSAT, and EUSPA helping them navigate complex hiring challenges in highly specialised and competitive talent markets.  And I can tell you that the hiring problem in space and deep tech is not what most founders think it is. It is not a sourcing problem. It is a systems problem.

Why Space Startup Recruitment Is Harder Than Any Other Tech Sector

Every startup struggles to hire. But space and deep tech companies face a set of challenges that SaaS founders never have to think about. The first is the experience cliff. There are plenty of fresh aerospace engineering graduates entering the market every year. There is also a generation of senior engineers who cut their teeth on legacy government programmes spanning a decade or more. What is missing is the middle. Mid-career professionals who have seen a full spacecraft programme from requirements through integration and operations. That group is small, and every company in the sector is chasing them.

The second challenge is timeline compression. Commercial space companies now routinely develop and launch satellites in two to four years. Traditional government programmes took ten. That means there is less runway to train junior engineers on the job, which makes experienced hires even more critical. And even more expensive.

The third is competition from organisations with bottomless budgets. SpaceX alone has pulled thousands of engineers out of the broader aerospace talent pool. Amazon, defence contractors, and national space agencies are all fishing in the same pond. A 50-person Space startup simply cannot match those compensation packages dollar for dollar. None of this is news to you if you are building in this space. What matters is how you respond to it.

What Happens When Founders Try to Handle Hiring Themselves

Most technical founders I work with are brilliant at building product. They are not brilliant at running a recruitment process. And there is no reason they should be.

Here is what typically happens. A round closes, and suddenly three or four critical roles need filling. The founder writes some job descriptions, posts them on LinkedIn, maybe reaches out to a few people in their network. Nowadays, AI-driven application tools have created a new problem. Companies are receiving hundreds, sometimes thousands of applications, many of them generated by bots or heavily automated profiles. Founders and hiring managers simply do not have the time to sift through the noise to identify who is genuinely qualified and who is not. Meanwhile, the strongest candidates are rarely actively applying for jobs at all. They are typically being headhunted through trusted networks or recruited by former managers and colleagues. Weeks turn into months. The roadmap slips.

Meanwhile, the founder is spending 30% or more of their time on hiring instead of product, strategy, or investor relations. That is not an exaggeration. I hear this number consistently from founders at the 10 to 60 employee stage. They know it is unsustainable, but they also do not have the budget or the need for a full-time Head of Talent.

This is the trap. Too big to handle hiring alone, too small to justify a dedicated hire. And traditional recruitment agencies, charging 20% to 25% of first-year salary per placement, burn through cash that post-funding startups cannot spare on repeat engagements.

How to Attract Engineering Talent When You Cannot Compete on Salary

The good news is that salary is not the only thing engineers care about. Especially not the kind of engineers who are drawn to deep tech.

Mission matters. A lot. The people who want to work on debris removal, Earth observation, or next-generation propulsion are not motivated purely by compensation. They want to work on problems that matter, with teams that move fast, in environments where their contribution is visible. That is something a 40-person startup can offer that a 10,000-person defence contractor cannot.

But mission alone does not close candidates. You need a hiring process that reflects the quality of the company you are building. That means clear role definitions so candidates know what they are walking into. It means structured interviews with scorecards so every interviewer is evaluating against the same criteria. It means moving fast. The best candidates in this market have multiple options, and a two-week silence between interview rounds is a guaranteed way to lose them.

Equity is another lever that founders often undersell. Early employees at space startups that go on to raise significant rounds or reach IPO can see life-changing returns. But if you do not articulate the value of that equity clearly during the offer process, candidates will default to comparing base salaries. And you will lose that comparison every time.

Building a Repeatable Hiring Process for a Scaling Deep Tech Company

Hiring in bursts is normal for space and deep tech startups. You might bring on five people in a quarter and then pause for six months while the next milestone is underway. The mistake most founders make is treating each burst as a fresh start rather than building a repeatable system.

A Talent Playbook changes that. It is a set of frameworks that codify how your company hires, interviews, evaluates, and onboards. It includes role templates, interview guides, competency maps, and decision-making criteria. You build it once, refine it as you grow, and use it every time a new role opens.

The companies I have worked with that scale successfully from 10 to 100 employees almost always have some version of this in place. Not because they are bureaucratic. Because they are disciplined. Consistent hiring standards are what stop a fast-growing company from making expensive mistakes when the pressure is on.

This also matters for governance. If you are PE-backed or heading toward a Series B or C, investors want to see that your people strategy is not just the founder winging it. Structured hiring processes, documented frameworks, and retention data are all signals that the company is ready to scale responsibly.

When to Bring in External Talent Advisory Support

If roles have been open for 90 days or more with no strong shortlist, that is a signal. If the founder is spending more time on recruitment than on building the business, that is a signal. If you have made a hire in the past year that did not work out within six months, that is a signal. And if your interview process changes depending on who is running it, that is a very clear signal.

A talent advisory retainer is not the same as hiring a recruitment agency. An agency fills a role. An advisor builds the system. They help you scope roles properly, map the market, structure your interview process, coach founders on closing candidates, and plan your workforce strategy quarter by quarter. They function as an on-demand Head of Talent without the full-time cost.

For companies between Seed and Series C, this model fits the reality of how hiring actually works. Flexible, senior-level support that scales up during hiring sprints and steps back when you are heads-down on delivery.

Let's Talk About Your Talent Strategy Before the Next Hiring Sprint

If any of this sounds familiar, I would welcome a conversation. I have spent 25 years working with space and deep tech organisations around the world, from partnerships with ESA and EUSPA through to scaling startups across six continents. I understand the market, the talent pool, and the unique pressures founders face when building teams in mission-critical sectors.

Whether you need help scoping your next three hires, building a Talent Playbook that grows with your company, or simply want a sounding board on your people strategy, I am here.
