The role

Engineers own product decisions at Spiko. We call this role the Product Engineer: an engineer who owns a feature end to end.

You are given a problem to solve and full ownership of how to solve it. You own the scoping, the architecture decisions, the implementation and the production release.

As a Senior Product Engineer, you also own one of Spiko's business areas: you are its main architect and the default reviewer of every PR inside it. You mentor more junior team members and help them grow their skills.

  • 5+ years of experience as a full-stack engineer
  • Excellent architecture and domain-modelling skills, and the habit of writing decisions down
  • Fluent with AI coding tools, with your energy going into product and architecture decisions
  • Product judgment: you enjoy talking to users, you know what to build and what to cut, and you can explain why
  • Comfortable working in an English-speaking environment
  • Curious, pragmatic, and eager to learn

Nice to have:

  • Experience in fintech, capital markets, Web3, or other highly regulated environments
  • Prior product ownership as a founder, a PM or the de facto product owner of your team
  • Hands-on experience with Effect or functional programming in TypeScript
