• Strong full-stack or backend engineering skills and demonstrated production shipping experience.

• Experience with Python, PyTorch, RL, ML evaluation frameworks and LLMs.

• Knowledge of distributed systems and data pipelines; relevant scraping, indexing, embedding or agent-harness work is valuable.

• A computer science degree and fluent English communication.

• Ability to work in the San Francisco office five days per week.

Bonus points

• Experience at creative technology, generative AI, crawling, indexing or data companies.

• Building agentic frameworks or evaluations for non-verifiable domains.

Why it works

3×

more interviews than doing it yourself with ChatGPT.

ChatGPT writes a CV and never learns what happened to it. We see every reply. For each CV we know:

  • How it was written, and how the review scored it
  • When we applied, and how long after the posting went up
  • Which posting, which company, which city
  • Who got the interview, and who heard nothing

That is how we know which CVs get called.
