Staff Backend Engineer

What You'll Work On

• System architecture: Designing how our agent infrastructure should evolve as we scale, making tradeoffs between speed, reliability, and complexity
• Hard technical problems: Owning the most ambiguous, highest-stakes projects where getting it wrong would hurt the business
• Technical strategy: Identifying gaps in our systems before they become problems and building the case for addressing them
• Engineering quality: Setting standards for code review, system design, and operational excellence through your own work

You Might Be a Fit If You

• Have 7+ years of backend engineering experience, with a track record of leading complex projects
• Have opinions about how systems should be built, and can articulate the tradeoffs behind those opinions
• Can take a vague problem and turn it into a clear technical approach without much guidance
• Write excellent code and hold others to a high standard without being a bottleneck
• Are energized by hard problems and comfortable with uncertainty
• Want to be hands-on at a company where staff engineers ship code, not just review it
• Have built systems that scaled and understand what breaks at each order of magnitude
