You didn’t start a space company to become an expert in recruitment metrics. But there’s one number worth understanding: time-to-fill, the number of days between opening a role and getting someone signed.
If you’re building a propulsion system or racing toward a launch date, you need guidance, navigation, and controls engineers, plus satellite RF specialists. So does every other well-funded company doing the same thing. The list of people who have built a flight-proven guidance system or shipped a satellite RF payload is short. Everyone’s calling the same names.
That’s why time-to-fill matters more in space than almost anywhere else. The engineers you need aren’t waiting around for you to make up your mind. Nail your sign-off process, and your time-to-fill goes down while your signed offers go up. Get it wrong, and you’re watching a competitor build the team you wanted.
Why Time-to-Fill Matters in Space Recruitment
A slow process costs more in some markets than others. In a client-driven market, it’s a nuisance. In a candidate-driven one, it means losing a great candidate to a competitor who has their sign-off process sorted. And space is about as candidate-driven as it gets.
A 2025 Aerospace Industries Association report, conducted with McKinsey & Co., found industry attrition running near 16% between 2021 and 2024, more than 10 percentage points higher than any other industry. Candidates are calling the shots at the offer stage. That’s why it’s worth checking a recruiter’s track record in the sector before choosing to work with them.
Time-to-Fill and Retention: Why Speed Alone Isn’t the Goal
In space recruitment, speed isn’t a nice-to-have, it’s what keeps the candidate on the table. A cleared, flight-experienced GNC engineer might be one of a handful available in the entire country. And they might be interviewing at two competitors who closed funding the same quarter. But speed alone isn’t enough. You could lose the candidate to a competitor who moved faster on the offer if you don’t have your internal processes sorted. A fast hire who doesn’t stick isn’t actually fast. You may be back to square one if you don’t balance speed with quality.
One of our recruiters has seen this play out firsthand. He helped build an engineering team that went from a couple of people to around forty-five over about three years. In that stretch, they lost exactly one person, and that was to a move abroad, not a competing offer. It’s also the kind of result worth asking any recruiter to show you.
It comes down to a deliberate process based on a winning recruiter-client partnership. The thing that will help you get your time-to-fill down without wasting time later is process.
What you don’t want is a rushed process where a job gets filled based on whoever is available fastest. A deliberate one makes sure you find someone who actually fits. And once you understand why cultural fit matters in hiring, it’s clear that fit is what keeps people around.
Bringing Your Time-to-Fill Down is a Team Sport
A good recruitment partner knows how to run a process that will get your time-to-fill down. But bringing down your time-to-fill isn’t only the recruiter’s job. A good way to think about it is a partnership where both parties agree on a process that will get their time-to-fill down. At EVONA, we call that the golden process. It’s built around SLAs we agree with a client upfront, tailored to whichever of our recruitment models fits the search. Stick to your half, and we commit to a timeline for filling the role.
In our experience, there are 5 things that help to get your time-to-fill down, without sacrificing fit. Some of it relies on the client, and some of it relies on your recruitment partner. Knowing what a good process looks like will help you to recognise a recruitment partner that will help you get your time-to-fill down, sustainably.
The 5 elements of a winning recruitment process
Where Client Input Makes the Difference
The intake call
You can’t fill a role if you don’t know what you’re looking for. That’s why an intake call is non-negotiable before sourcing starts. A recruitment team that knows their stuff will always insist on this. Your job is to know what you want and to be available to talk through the job description.
The best recruitment partners want to know these things before sourcing:
- The non-negotiable skills versus what you can live without
- The salary band
- Who signs off on a CV
- What “good” looks like beyond the job title
It sounds basic, but it’s the single biggest predictor of whether a search will go smoothly or go south halfway. When expectations aren’t clear from the get-go, everything downstream gets much harder and slower.
A real-time channel:
If speed matters, email is where searches go to stall. A recruitment team that takes speed seriously will insist on setting up a real-time channel before the first candidate is even sourced. All you need to do is stay reachable, whether you decide on Slack, Teams, or even a text thread. Agree on a default channel for anything time-sensitive. If email is your only channel, a strong candidate found on Tuesday is often gone by Friday, or already interviewing somewhere else.
A weekly check-in:
No news is not good news when it comes to recruitment. Founders don’t usually lose confidence in a recruiter because a search is hard. They lose confidence because they don’t know what’s going on. A recruitment team worth keeping will get in touch every week without fail. All you need to do is show up for fifteen minutes a week. A check-in is not optional, because a client who feels informed is a client who trusts the process. And as we said before, a deliberate process is what will get your time-to-fill down.
What the Recruitment Partner Owns
The last two are on your recruiter. The first is a sourcing checklist: a structured list covering intake notes, direct database search, targeted outreach, live postings, and site traffic.
It exists because a search built from memory leans on whoever a recruiter already knows, and in a specialist space like this, that shortlist runs dry fast.
A recruitment team that knows this market won’t let memory decide where a search starts. A good partner runs that checklist in full on every search, so the whole field gets covered instead of whatever channel is easiest.
Running a solid process is what makes a recruitment partner reliably fast. So before you choose a recruitment partner, ask how they handle these five things. If they can answer without hesitating, you’re in good hands. Your half is simple: show up, stay reachable, and give them fifteen minutes a week.
