At Weave, our mission is to evolve how therapeutic knowledge is captured, transformed, and communicated throughout drug development. We do this by equipping human experts with AI instruments to enable drugs to be brought to patients as rapidly, safely, and inexpensively as possible.

The Weave Platform streamlines regulatory workflows from start to finish by intelligently, creatively, and effectively infusing every step with AI. Together with our customers, Weave is designing and building the AI workbench for the entire therapeutic lifecycle.

We’re looking for a Staff Backend Engineer, reporting directly to the Backend Engineering Manager, that can navigate between data, AI, and backend systems. Stability, performance, and reliability of the AI system are the core responsibilities. You will be asked to develop novel solutions to customer problems, characterize the results, and deliver the solutions into production. You’ll be successful in this role if you can go from idea, to experiment, to testing, to production without getting lost or stuck at one of the steps. We care more about solving problems than using the latest buzz. We prefer simple, well-tested, stable solutions that are dependable, yet impressive.

  • Working with Product and Design to quickly find solutions
  • Writing performant, simple code. We run Django + Python + Postgres + Redis.

  • 8 years of experience or more of Django in a production environment
  • Used of LLMs in production
  • Directly interacting with LLMs without abstraction libraries
  • Humble, hungry, and smart
  • Able to move quickly on tasks while producing high-quality results
