Founding AI Engineer

About Fleetcraft
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.

Why Join Us?

We’re building at the intersection of aerospace and AI - modernising one of the world’s most complex and critical industries.

• Solve real-world problems: Your code won’t just ship; it will define how aircraft are inspected, maintained, and trusted worldwide.

• Join from the start: We’re growing fast and already working with some of the largest aviation companies in the world. You’ll be here from day one, helping shape the future.

• High trust, high ownership: Make decisions that move the whole company forward. We value autonomy, speed, and impact.

• Stack: Build with modern tools — Python, FastAPI, TypeScript, LLMs, MLOps

What We’re Looking For

• 2+ years of software development experience

• Hands-on experience building production AI systems with Python, PyTorch, and LLMs (OpenAI, Anthropic, etc.), integrated into real user workflows

• Familiarity with MLOps tools and CI/CD for both traditional and ML-driven systems

• Strong backend and API development skills - comfortable owning systems end-to-end, from data pipelines to user-facing interfaces

• Passion for building clean, usable products that solve real problems, fast

• Comfortable wearing multiple hats, challenging assumptions, and shaping product direction in ambiguous environments
  

Bonus Points

• Prior startup or 0→1 product experience

• Contributions to open-source AI/ML projects

• Experience with aviation, aerospace, or other safety-critical domains
  

Tech Stack

• Core: Python, FastAPI, TypeScript, React

• AI/ML: OpenAI, Anthropic, computer use, evals, voice agents

• Infrastructure: Azure, Docker
  

Process:

1. Initial Screen (30 min video call with one of the founders)

2. Interview (45 min video call with both founders)

3. Take-Home Test (HackerRank assessment)
