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 Founding Senior 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 senior engineers who want to shape the technical foundations of the platform and have a direct impact on the product.

What We Do
AI is reshaping science. Tracer ensures it delivers.
Scientific breakthroughs depend on AI but today’s computational infrastructure isn’t built for the scale, speed, and complexity of modern research. Tracer provides real-time visibility, optimization, and debugging across every workload, ensuring AI-driven discovery happens faster, more efficiently, and at lower cost.
From drug development to semiconductor design, we eliminate bottlenecks, speed up supercomputing, and make AI a reliable, scalable engine for scientific progress.
Our seamless integration requires just one line of code. Your data never leaves your system.
The next era of science demands the right foundation. Tracer builds it.
