Kraków or Gdańsk, Poland

We are looking for a product-minded Full-stack Software Engineer to join our Claiming Experience team, responsible for the journey that helps travellers start, complete, and submit their claims with confidence.

What you'll achieve:

• Build and evolve the core claiming flows, across frontend and backend, all the way to production.
• Work with Product, Design, and Data to spot friction, frame the problem, and ship measurable improvements.
• Design and run experiments that lift submission rates and reduce confusion and make it easier and safer for the whole team to do the same.
• Integrate the claiming flow with the systems around it: documents, comms, claim processing, partner APIs, internal tooling.
• Modernise the legacy parts of the journey so the team can move faster with less risk.
• Raise the bar on reliability and observability for these flows, so we catch and fix issues before they cost a traveller their claim.
• Hold the line on engineering quality through reviews, testing, and pragmatic technical decisions.
• Use AI-assisted workflows where they genuinely speed you up or improve the work.

Requirements:

What sets you apart:

• 4+ years building and owning client-facing production apps where reliability, performance, and conversion actually matter.
• Strong in at least one of our core technologies: TypeScript/React, Ruby/Rails, Node.js and willing to work across the stack.
• A product instinct: you care whether the code solved the right problem, not just whether it shipped.
• Comfortable across the full lifecycle: framing, building, testing, deploying, monitoring, iterating with the testing discipline to back it.
• Solid with relational databases, ideally PostgreSQL.
• An ownership mindset: you go looking for the important problems instead of waiting for a perfect ticket.
• Clear communicator in English, written and spoken.
