About Tracer

Many scientists struggle to debug broken bioinformatics pipelines they use for research, which slows down the velocity of new scientific breakthroughs like drug development , that could help millions of people. To fix this, we're building an advanced observability platform for high-performance computing. Backed by $3M in funding from top investors and located in the heart of London, we're assembling a founding team to accelerate. Ready to make an impact?

Your Mission

As a Junior Engineer, you'll focus on developing our core observability platform along with our founding engineering team. You'll contribute to key architectural decisions and write production code; you'll also tackle some of the most complex engineering challenges we encounter. This role is ideal for engineers who want to shape the technical foundations of the platform and have a direct impact on the product.

Our Core Values

Passion → We lead with passion. When we care deeply about our work, great things follow.

Intelligence → We face the hard truths, ask the right questions, and solve problems as a team

Fun & Fearlessness → The best work happens when you’re having fun and taking on big challenges.

Hard Work →We work really hard, but live a life worth living - and take epic holidays.

Experiment → We experiment relentlessly in pursuit of truth, learn fast, and iterate faster

Meritocracy → Like a professional sports team, we focus on contribution and reward excellence.
