Lead Staff Software Engineer - SCORE

Requirements:

  • You operate at a Staff engineer level, a recognized technical authority that other engineers turn to for guidance on hard problems.
  • You have hands-on experience building and operating backend systems for a web or data platform of meaningful scale.
  • Experience with C#/.NET and SQL is a strong plus, though not required. What matters most is depth with backend systems generally.
  • Experience designing or building GraphQL and/or REST APIs is a plus.
  • Experience with reporting or scheduled-reporting systems is a plus.
  • Experience building AI or agentic systems is a plus.
  • You're actively seeking a path into people management, not just willing to tolerate it. You can point to some experience mentoring, leading, or informally guiding other engineers already.
  • You operate independently in ambiguity, scoping, sequencing, and driving execution on complex backend problems without much hand-holding.
  • You communicate clearly with engineers and non-technical stakeholders alike, including around trade-offs and risk.
  • You take ownership of what you build in production, not just what you ship.

What You'll Be Doing:

  • Design, build, and operate backend systems supporting a high-traffic web and data platform, as a Staff-level technical authority on the team.
  • Act as a technical reviewer and mentor in design and code reviews, raising the engineering bar for the team.
  • Drive technical direction on ambiguous, cross-cutting problems, balancing reliability, performance, and delivery speed.
  • Partner with adjacent teams and platform governance groups to align on shared standards and systems.
  • Ramp up on our systems and technical domain first. From there, you'll take on direct management of a senior engineer, with a short runway to grow into leading a larger engineering team as we scale headcount in London.
  • This role is a deliberate growth track toward people management. We're looking for someone who actively wants to build and lead a team over time, not someone content to stay purely IC indefinitely.
  • Once you're managing, you'll run regular 1:1s, own performance and growth conversations, and take part in hiring as the team scales.
  • Represent your team's technical direction and staffing needs in cross-functional planning.

Nice to Haves:

  • Experience with C#/.NET and SQL is a strong plus, though not required. What matters most is depth with backend systems generally.
  • Experience designing or building GraphQL and/or REST APIs is a plus.
  • Experience with reporting or scheduled-reporting systems is a plus.
  • Experience building AI or agentic systems is a plus.

Perks and Benefits:

  • Opportunity to work on large-scale distributed systems
  • Chance to tackle petabyte-scale data challenges and machine learning
  • High-stakes and high-visibility projects in the infrastructure behind AI agents
  • Growth and learning opportunities in a global team
