This is hands-on feature development on a mature product with real users. The team works AI-first, with tools like Claude Code as a natural part of daily development. You will not deal with end clients directly - your focus is the code and the product.

  • Be accountable for the quality, architectural decisions and maintability
  • Use AI tools such as Claude Code as a natural part of your workflow
  • Collaborate closely with product, design, backend and QA
  • Research and bring in new technologies that improve the product

Requirements:

We know that sometimes, you can't tick every box. We would still love to hear from you if you think you're a good fit!

  • 4+ years of experience as a frontend developer
  • Strong TypeScript, HTML, CSS and JavaScript
  • Strong and recent experience with React and it’s ecosystem building large-scale, customer-facing applications
  • Experience building complex UIs with tables, forms, graphs and dashboards
  • Experience with unit testing (Vitest or Jest)
  • Experience connecting the frontend to backend services (GraphQL or REST)
  • Daily use of AI coding tools (e.g. Claude Code, Cursor, Copilot)
  • Proficient in verbal and written English communication

Desirable:

  • Experience with GraphQL and Apollo Client
  • Material UI (MUI)
  • Charting libraries (e.g. Victory, Recharts)
  • Real-time UIs (WebSockets, subscriptions, live dashboards)
  • Basic understanding of CI/CD (GitHub Actions, Kubernetes, Helm)
  • Background in cybersecurity, monitoring or automotive / IoT products

What’s in it for you?

  • Flexible working hours
  • Home office option
  • 5 weeks of holiday
  • 5 sick days
  • Multisport Card
  • Meal allowance
  • Internal trainings including workshops and seminars
  • Paid certifications and technical as well as soft-skills training
  • Possibility to participate in international conferences

Why it works

3×

more interviews than doing it yourself with ChatGPT.

ChatGPT writes a CV and never learns what happened to it. We see every reply. For each CV we know:

  • How it was written, and how the review scored it
  • When we applied, and how long after the posting went up
  • Which posting, which company, which city
  • Who got the interview, and who heard nothing

That is how we know which CVs get called.
