Data Scientist, Performance and Reliability

Cursor Cursor · Coding AI · San Francisco, CA · Engineering

Data Scientist focused on measuring and improving the performance and reliability of Cursor's AI-powered coding tools, including the agent harness, by designing metrics, building measurement frameworks, and partnering with engineers on data tooling.

What you'd actually do

  1. Design and operationalize metrics that measure the stability of product surfaces and the agent harness
  2. Build a measurement and rollout framework to prevent, detect, and root cause performance regressions
  3. Partner with engineers on data tooling that enables self-serve analysis
  4. Identify performance and reliability experiences that disproportionately cause user frustration
