About the Role

We're now looking for a Founding Principal Engineer, who together with the other founders will work as a full-stack on building out our core observability platform in London. Your work is a crucial role in influencing not only the product, but also transforming high-performance computing.

You'll love our tech stack

  • Rust (because we like our code like we like supercomputers - insanely fast)

  • ClickHouse (regular databases just can't keep up with our data)

  • AWS + Terraform (infrastructure that builds itself)

  • + TypeScript (because front-end should be sexy too)

Key Responsibilities:

  • Architect and develop our Rust-based client for robust data ingestion

  • Design and implement advanced features including:

  • Data ingestion connectors

  • Logs management systems

  • Intuitive observability interfaces

  • Sophisticated error resolution tools

  • Drive core architecture decisions and lead platform deployment on customer cloud environments

  • Collaborate closely with cross-functional teams to align technical solutions with business objectives

  • Educate and guide other engineers, fostering a culture of engineering excellence

What We Are Looking For:

  • 5+ or ideally 10+ years veteran in Software Engineering

  • Strong background in high-performance data infrastructure, cloud computing, data science, or observability space

  • Proven track record of shipping products at high velocity

  • Experience working at an early-stage observability/cybersecurity startup and bonus points for having joined earlier.

  • Ability to work in a fast-paced environment and wear multiple hats

Our Recruitment Process

Introductory Call mins): Call with our hiring manager to discuss your background, motivations, and learn more about Tracer

Role Fit Interview (45 mins): Meet with your manager or a similar-level team member to review your working style, skills, and fit for the role

Take-home & Competency Deep Dive (1 hour): Complete a practical exercise (e.g., case study, presentation, or technical problem-solving) to explore the role's responsibilities and expectations

On-site meetup (Half Day): On-site interviews and team lunch at our headquarters to ask any questions and experience our office and culture firsthand
