Berlin, Krakow or Lisbon

As a Fullstack Engineer on this team, you’ll be instrumental in building the systems and tools that power synthetic testing, evaluation, and quality validation for our AI agents. While this is a fullstack role, it leans more on backend development, we’re looking for someone who is passionate about APIs, event-driven systems, testing infrastructure, and data workflows, while also being comfortable crafting user-facing tools and owning delivery end-to-end.

You’ll work closely with product managers, designers, data engineers, data analysts, and fellow developers to create seamless, intuitive experiences — combining rich data, intelligent systems, and responsive UIs.

Your work will directly shape how our customers make informed and impactful decisions based on real-time, AI-powered insights.

What You Bring to the Role

• 3+ years of experience building modern web applications using TypeScript, React, and Node.js.
• Familiarity with REST APIs, data fetching strategies, and integrating with external services.
• You write clean, modular, and tested code — and you value maintainability as much as speed.
• Experience working with design systems and component libraries, with a strong focus on performance, accessibility, and usability.
• You are a product-minded engineer — you care deeply about the end-user experience and proactively contribute ideas to improve product outcomes.
• Excellent communication skills and a proactive mindset — you collaborate well in cross-functional teams, aren’t afraid to ask for help, and enjoy enabling others.
• A drive for continuous learning, reflection, and improvement — in both your own growth and your team’s success.

A big plus if you

• Are familiar with AWS, and comfortable with CI/CD pipelines.
• Have a good understanding of microservice architecture and event-driven systems and basic database design (relational and NoSQL).
• Have experience using AI agentic tools such as Cursor, Claude Code, and similar developer assistants
• Have working knowledge of Python and experience using it in backend, automation, or data-related tasks.
