Product Engineer

Centaur Labs has developed a novel approach to labeling medical data at scale, unlike any other product. Users of our mobile app DiagnosUs compete for prizes that we award based on how well they label our customers' images, videos, audio, and text data. Our investors include Accel, GFC, and Y Combinator.

We're looking for an ambitious Product Engineer who can help us tackle a number of exciting challenges:

  • How do we convert laborious work that currently takes expensive experts a long time to do -- like segmenting all the slices of a 3D brain scan -- into small, high-throughput tasks that can be done quickly on a phone?
  • How do we use cash prizes to incentivize labelers to try their best while anticipating and plugging loopholes that would allow users to game the system?
  • How do we let anyone in the world use our app while preventing any individual from downloading or scraping the proprietary medical data they're labeling?


  • You're a generalist software engineer with backend experience and native mobile experience.
  • You've been responsible for merging and deploying production code for a product where security and reliability can't be sacrificed.
  • You're well-organized and capable of making processes more efficient for yourself and your colleagues -- even amid the unpredictability and occasional chaos inherent in a small startup.
  • You have at least five years of engineering experience.

Preferred Skills

  • Bachelor's degree in computer science or equivalent
  • Experience using Swift
  • Experience with game design
