About the role

We use geographic cost of labor as an input to develop ranges for our roles and as such, each location where we hire may have a different range. If this role is remote, we have listed the top to the bottom of the possible range, but we will specify the target range for an exact location when you are selected for a recruiting discussion. For more information on our compensation philosophy, see our website .

What they're looking for

  • A Bachelor’s or Master’s degree in Computer Science, Mathematics, or a related technical field, or equivalent depth from experience
  • 6+ years building software professionally, with at least 2 of those building ML systems that run in production
  • You’ve built and maintained APIs, worked with CI/CD pipelines, and shipped code that other engineers depend on
  • Comfort with and enthusiasm for AI-assisted workflows, experience using LLMs, code-generation tools, or agentic systems in production or operational contexts is a strong signal
  • You use AI tools (Copilot, Claude, etc.) to move faster, but you understand every line they produce. You can spot AI slop and you don’t ship it
  • An A-player mindset with a strong bias for action: you raise the bar, move with urgency, stay resilient through ambiguity, and take ownership to deliver meaningful outcomes
