Founding Product Engineer

Aerospace represents the best of human engineering. Yet the systems that build and maintain aircraft are slow, manual, and barely changed in decades - and with a mounting shortage of personnel and parts capacity, the industry has to change to grow.

We're reshaping how aircraft are maintained and manufactured, to make innovation faster, cheaper, and more accessible across the entire industry. We're already working with MROs on three continents.

Our seed was led by Susa Ventures (a 1-in-10 unicorn hit rate), who doubled down a year later at 2× the valuation, alongside Liquid 2 VC, early backers of Anduril and Stoke Space.

You'll work with a team that has helped launch airlines and put satellites into orbit - and with our aviation advisory board, whose members have run some of the largest aircraft OEMs, led airworthiness at Gulfstream, and overseen training facilities that educate a quarter of all aircraft mechanics in the US.

The Role

Join as the third founding engineer at Fleetcraft to build the core product - software that defines how aircraft are inspected, maintained, and trusted worldwide. We're already working with some of the largest aviation companies in the world and growing fast. If you want high ownership, real architectural decisions, and code that ships into one of the most complex industries on earth, this is for you.

What you'll do

• Build and ship full‑stack product end‑to‑end - data pipelines, API integrations, and frontend
• Design and deploy AI/LLM‑powered features integrated into real user workflows
• Design, build, and refine product flows that users can rely on without friction
• Own full features from day one, making real architectural decisions

What we're looking for

• 2+ years building and shipping production software across the full stack
• Hands‑on experience with AI/LLMs in real user‑facing systems
• Strong UX instincts – you care about how software feels, not just how it works
• Experience with ETL, data pipelines, or system integrations
• Bonus: prior startup experience
• Core: Python, FastAPI, TypeScript, React

Process

• Initial Screen (30 min video call with one of the founders)
• Interview (45 min video call with both of the founders)
• Take‑Home Test (1h45 on HackerRank)
• In‑Person Interview

Working at Fleetcraft

Our office is in central London, in Fitzrovia. Being in the same room helps us move fast, make better decisions, and build with urgency.

We're comfortable with chaos and energised by the pace. We also get that life isn't always predictable. When something personal comes up, we trust each other to handle it with flexibility and maturity.

We’ll back you to do your best work. Need to relocate? Working late? Want a tool that helps you move faster? We’ve got you. Just tell us what you need we’ll make it happen.

Fleetcraft is an equal opportunities employer.
