About Us
Tracer is an early-stage, venture-backed startup building autonomous AI agents for production data pipelines. We are backed by experienced operators and investors who believe AI for production systems will be one of the defining enterprise software categories of the next decade. Our team is small, senior, and highly execution-focused.
About the Role
Tracer is building agentic alert investigation for production data pipelines. We're hiring a Founding Senior Backend Engineer in London to own and build the core systems that turn production alerts into grounded RCAs and fix suggestions for a small set of high-value alerts. This role combines backend systems with product engineering and customer problems, with the goal of turning real production pain into reliable, production-grade systems engineers trust and use.
You’ll Love Our Tech Stack
- Python + LangGraph (for multi-agentic alert investigation)
- Rust (because we like systems that are fast and correct)
- ClickHouse (high-volume event + investigation history at scale)
- AWS + Terraform (infrastructure that builds itself)
- TypeScript (because front-end should be sexy too)
What You’ll Do
You’ll own the core systems that turn an alert into a defensible investigation and RCA. In practice, you will:
- Architect and build the core alert, investigation, root cause analysis (RCA) pipeline in Python
- Design and implement key systems including:
- Alert ingestion + normalization
- Context enrichment + correlation
- Problem framing outputs
- Hypothesis orchestration engine
- Investigation execution runtime
- Investigation artifacts + reporting
What We’re Looking For
- 5+ years (ideally 10+) professional software engineering experience.
- Proven track record of shipping real products at high velocity.
- Strong backend and distributed-systems foundations, ideally with experience in data platforms and production pipeline stacks and incident/observability tooling.
- Experience working at an early-stage startup and bonus points for having joined earlier.
- High ownership and sharp product instincts: you build what matters and cut what doesn’t.
Compensation & Benefits
Total Compensation Range: £150,000 – £220,000+ (salary and equity value). We structure compensation as follows:
- Competitive base salary
- Meaningful equity ownership with real upside
Final package depends on experience, impact, and seniority. What’s included:
- Salary + equity (equity typically ~0.3% – 2%+)
- 30 days annual leave
- Employee health insurance
- Visa sponsorship
- Weekly team dinners and socials
- Regular team offsites and trips (our most recent was Kenya)
- The satisfaction of building a world-class AI-powered product with an exceptional team
