Description

Senior Product Engineer

Location: Zurich

Department: Engineering

Location Type: IN_OFFICE

Employment Type: FULL_TIME

About the Role

As a Senior Product Engineer on our Product Engineering team, you'll own features from idea to production — and stay accountable for whether they actually work for users. Depending on where the biggest challenges are, you could be working across our Core ai, Apps, Marketplace, or Integrations.

This isn't a role where someone hands you a ticket. On Monday you might prototype a new conversation-to-application flow with a designer. By Wednesday you're debugging a tricky inference issue. By Friday it's live and you're watching how users respond. The cycle is short because the team is small and the surface area per person is large.

What You'll Actually Do

  • Take product problems end-to-end — from data model to deployed interface — without waiting for someone to scope a lane for you
  • Prototype fast, ship often, and instrument everything so you know what's working before anyone asks
  • Push back when something doesn't feel right — UX, architecture, scope — and bring an alternative, not just the objection
  • Use AI aggressively to move through unfamiliar territory — we build AI tools, and we expect you to use them to build faster than any one person should be able to
  • Work directly with product and design to shape what gets built, not just how


You Might Be a Great Fit If…

  • You've shipped products where you owned the product decisions, not just the technical ones — and you can point to something real that users loved
  • You instinctively reach for AI when facing an unfamiliar part of the stack — not because you can't learn it, but because you know the faster path to a working solution
  • You care as much about how software feels as how it's built — a clunky interaction bothers you the same way a bad abstraction does
  • Ambiguity doesn't stall you — you create enough structure to move, then stop structuring and ship
  • You close loops without being prompted — options, not problems
  • You're energised by small teams where your work reaches real users within days, not quarters


Practicalities

  • Location: Zürich, Switzerland — full-time on-site. We don't offer remote or hybrid arrangements.
  • Stack: TypeScript across the stack — React, Node.js, SQL/NoSQL. Familiarity matters more than years.
