Fullstack Engineer (Frontend-focused)

We are looking for a Cloud Fullstack Engineer (Frontend-focused) who will own the frontend but is also comfortable contributing to backend APIs, serverless functions and data workflows.

Our aim is to deliver seamless, data-driven experiences and dashboards for our customers — if you enjoy building complex UIs and visualizations while shaping the architecture behind them, this role is for you.

What’s cool about this job?

You’ll take ownership of a modern frontend stack in a cloud environment, work with real-time data visualizations at scale, and collaborate with a small, senior team.

About the role

This is a B2B/freelance role. We’ll give you clear objectives and a lot of autonomy — perfect for someone self-driven who enjoys crafting polished interfaces and also isn’t afraid to jump into backend/serverless code when needed.

You’ll work closely with other engineers, designers and product owners. We’re looking for someone who not only delivers features but also looks for smarter, faster ways of building things.

Core hours of the team - 10:00 and 18:00 CET, with some client meetings scheduled up to 20:00 CET (approx. 2 per week).

What you’ll do:

• Own our frontend architecture and implementation.

• Design and build new user-facing features using React.js and TypeScript.

• Contribute to backend app APIs, serverless functions and data integrations.

• Develop and integrate dashboards, visualizations and real-time data features.

• Ensure usability, accessibility and performance best practices (WCAG, ARIA).

• Help shape our logging and monitoring dashboards beyond Grafana (Datadog, New Relic, etc.).
