About Tracer

Many scientists struggle to debug broken bioinformatics pipelines they use for research, slowing 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?

About The Role

As our Founding Product Engineer, you'll have the rare opportunity to design, build, and launch every user-facing experience for web and mobile from scratch . You will be solely responsible for developing and maintaining the entire front‑end and full‑stack systems, integrating with backend services and infrastructure.

Full‑stack experience is required, you'll manage everything from infrastructure through backend connections to UI. This role offers large autonomy and responsibility, ideal for someone ready to lead technically and shape the product foundation.

Key Responsibilities

• Architect, build, and deploy full‑stack applications using Next.js, TypeScript, and related technologies
• Fully own web and mobile features end to end:
• Real-time observability dashboards
• Advanced data visualisations
• Backend integrations and data flow
• Deploy, maintain, and scale applications independently with Vercel and AWS
• Connect front‑end systems to backend databases (Clickhouse) and internal APIs
• Establish engineering standards, build foundational tooling, and support future hiring
• Partner closely with design, product, and backend teams to ensure cohesive development

• Comfortable working autonomously in a fast‑moving, early‑stage environment

Bonus Qualifications

• Experience with Clickhouse or other high‑performance data platforms
• Prior experience as the sole or lead engineer on major product launches
• Early‑stage startup or entrepreneurial experience
• Core: Next.js, TypeScript, Vercel, AWS, Clickhouse
• Additional (not required): Rust (backend), Nextflow, AlphaFold, Terraform, eBPF

Note: Full‑stack experience is required. Additional tech experience is beneficial but not essential—adaptability, fundamentals, and curiosity are our priorities.

• A link to your portfolio, GitHub, or live products built from scratch
• A short write‑up outlining your most impactful technical achievement, your role, and key learnings

Interview Process (subject to change)
