Founding Engineer | Agentic AI Startup

We’re partnering with an exceptional startup founded by two very well-educated, second-time founders who are tackling a huge legacy industry with an AI-first approach.

  • Build and ship core product features end-to-end
  • Design scalable backend systems, APIs, and integrations
  • Develop AI agents, LLM workflows, and retrieval systems
  • Own technical decisions and shape engineering culture
  • Work directly with customers and founders to solve complex real‑world problems

What we’re looking for

  • Strong backend engineering experience, ideally with Python
  • Experience building AI products, agents, RAG systems, or LLM‑powered applications
  • High agency with a founder mentality
  • Proven track record of shipping quickly and taking ownership
  • Strong product instincts and excellent communication skills

Work alongside exceptional second‑time founders

Backed by one of Europe’s standout pre‑seed rounds

If you want the chance to join at day zero and help build something genuinely category-defining, let’s talk.
