About the job
- Design systems, deploy them into production, observe operators using them, and iterate until they become essential to operations.

- Build evaluations, feedback loops, and training pipelines to help AI reliably complete specific jobs.
- Ship solutions into daily production use rather than pilots or proofs of concept.
