Full-stack Software Engineer

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.

Salary:

• If you join us as a full-time employee: 14.000 - 20.000 PLN gross/month

• If you join us as a contractor (for specific projects): 15.000 - 25.000 PLN net + VAT on a B2B contract

What you can expect from us

• Opportunity to build high-leverage features and tooling for the core business domains that directly impact the travel experience for millions of users.

• Culture that promotes good engineering practices, high-quality code, and continuous improvement.

• Daily deployments to production, ensuring fast impact and iterative development.

• Access to a modern tech stack and a variety of functional areas, including:

  • Backend: : Node.js and Ruby on Rails

  • Frontend: TypeScript-first React ecosystem (Vite, Turborepo, TanStack Query/Table, Zod)

  • Databases: PostgreSQL

  • Infrastructure:  AWS, Docker, Kubernetes, Terraform.

  • Monitoring: ELK/Grafana, Sentry, GitHub Actions CI/CD

  • Testing: Bruno (API), Playwright (E2E), k6 (performance)

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.
  

A year in, you'll have measurably improved how many eligible travellers complete their claims, made experimentation faster and safer, and simplified enough of the codebase that the team ships with more confidence than it does today.

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.
