Job Description

Join as the third founding engineer at a $3.2M seed-stage startup backed by Susa Ventures and Liquid 2 VC.

This is a high-ownership role shipping full-stack products for global MROs, making aerospace innovation faster, cheaper, and more accessible.

Location

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.
