Senior Front-End Engineer
Own the frontend experience across platforms used by millions
At Gomibo, we build a lot of what we use ourselves – especially where custom development adds real value. We rely on open-source libraries where it makes sense, and build our own solutions when off-the-shelf tools fall short. Together, this powers the webshops and tools we use in 30+ European countries. As a Senior Frontend Engineer, you'll lead the technical direction of major frontend initiatives: refactoring legacy code, evolving our design system, and shaping how we scale React apps across our platform.
This is a hands-on engineering role. You'll write code, make architectural calls, mentor teammates, and work closely with product, design, and backend to ship great features.
What you'll do
You'll join a cross-functional team with frontend and backend developers, product designers, and product managers. You'll take ownership of frontend decisions and raise the bar for how we build modern UIs at scale.
Some things you might tackle:
● Replace a legacy module with clean, composable React components
● Improve frontend performance and developer experience using NodeJS, React, React Router v7, and TypeScript
● Guide our design system strategy and improve component reusability
● Pair with teammates on gnarly bugs or refactors
● Hunt down weird edge cases (like the one device in the office where the modal still misbehaves)
● Giving input on roadmap priorities and team planning
● Mentoring other engineers and leading by example in how we collaborate and grow
We believe the best idea should win – regardless of who it comes from. Everyone contributes to how we build and improve things, from design reviews to deployment decisions.
