✅ Your missions

As Head of Engineering, you'll build and lead the engineering team that delivers Ooak Data's core product to frontier labs. You'll report directly to Thomas (CTO & co-founder).

The role has three layers:

Own the ingestion and anonymization platform. You lead the squad that plugs into our partners' tools, ingests full company data ecosystems, and anonymizes them into structurally identical digital twins. This is the heart of what we ship to the labs: the volumes, the quality, and the trust of our partners depend on it. Manage your squad. Hire, onboard, and grow the engineers in your perimeter. Set the pace, the priorities, and the delivery rhythm. Lead engineering across the company. Transverse management of all software and data engineers: engineering practices, technical standards, architecture decisions, code quality, hiring bar, and career growth.

Concretely, over your first 12 months:

Scale the team with the founders: interviewing, closing, onboarding. Structure the engineering org: squads, rituals, delivery process, documentation, on-call, and the way we work with product and ops. Ship at scale: the ingestion and anonymization pipeline has to absorb hundreds of company data ecosystems over the next year, reliably and with auditable quality. Set the technical direction with Thomas: tech choices, design patterns, scalability, security, and infrastructure. Stay hands-on at the start: you code and review in the first months, then step back as the team grows.
