Job Title

Founding Product Engineer

Salary

£80k-£120k + Equity

Company Description

Fleetcraft – Susa Ventures backed aerospace startup

Job Description

Join as the third founding engineer at a $3.2M seed-stage startup backed by Susa Ventures and Liquid 2 VC. You will build AI-powered software infrastructure that digitizes aircraft maintenance, replacing decades-old manual processes. This is a high-ownership role shipping full-stack products for global MROs, making aerospace innovation faster, cheaper, and more accessible.

Location

London, UK

Why this role is remarkable

  • Rare opportunity to join as the third founding engineer, working alongside a world‑class team from Oxford, Otta, and ESA‑funded satellite projects.
  • Exceptional financial backing from Susa Ventures (1-in-10 unicorn hit rate) and Liquid 2 VC, early investors in Anduril and Stoke Space.
  • Direct impact on the aerospace industry, building AI/LLM‑powered systems already saving global maintenance providers over 32 hours per month in documentation.

What you will do

  • Build and ship full-stack product end-to-end, including data pipelines, API integrations, and React-based frontends.
  • Design and deploy production-ready AI/LLM features, such as voice‑to‑record agents, integrated into critical aviation workflows.
  • Own major architectural decisions and feature development from day one, ensuring software meets the rigorous demands of aircraft certification.

The ideal candidate

  • 2-3 years of professional experience building and shipping production‑grade software across the full stack (Python/FastAPI/TypeScript).
  • Strong UX instincts and hands‑on experience integrating AI/LLMs into user-facing systems that feel intuitive and reliable.
  • Proven ability to navigate startup chaos and manage complex data integrations or ETL pipelines within a fast-moving engineering environment.
