Full-Stack Software Engineer

AirHelp is a global travel tech company on a mission to make every journey smoother. We built our name helping millions of travellers claim the flight compensation they're owed - and that's now the foundation of a broader platform of travel protection and convenience products spanning the entire journey. 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. It's one of the highest-leverage surfaces in the company. What happens here moves submission rates, traveller trust, and the cost and speed of everything that happens downstream - legal, documents, operations, comms. Small wins compound. The claiming journey is a real product problem that happens to span frontend, backend, experimentation, document and signature flows, legal requirements, partner integrations, and production reliability. You'll own meaningful parts of it end to end, working day to day with engineers, PMs, designers, data analysts, and QA. This is a hybrid role based in Kraków or Gdańsk.
