Preferred Experience

10+ years in software engineering, including 3+ years managing engineers (teams of 4-5 people or more, including senior profiles).
Strong back-end depth on data-intensive systems: Python or Rust in production, SQL, distributed pipelines, cloud infrastructure (GCP or equivalent).
AI-native way of building: you have been building with coding agents every day for months, and you know how to make a team ship faster and safer with them. At Ooak, every engineer runs several Claude Code sessions in parallel.

High bar on quality and security: we handle our partners' most sensitive data.
Team first, low ego: you lead by clarity and trust, and you make the people around you better.
Fluent English, mandatory (working language with our clients and the labs).

Experience with data anonymization, privacy, or security-sensitive systems.
Strong interest in AI, RL environments, and how frontier models are trained.
TypeScript on the side, for the platform.
