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.
