They cannot train them to work: navigating a real company's Slack threads, half-finished Notion docs, contradictory Jira tickets, and permission boundaries. That requires real enterprise data, and you cannot synthesize it. You have to source it.\nWe plug into enterprise tools, anonymize everything into a structurally identical digital twin, and generate reinforcement-learning environments with expert-level tasks calibrated against frontier models.\nWe are a Y Combinator company with 8 figures contracts signed with frontier AI labs, and we are scaling delivery aggressively over the next months.\nOur values\nTrust, the foundation of every relationship, internal and external. We extend it by default and value the ownership that comes with it.\n\nAmbition, we commit, we move fast, with tenacity and efficiency.\n\nCollective, team first, low ego.\n\nKindness, at the heart of every interaction.\n\nThe offer\nLocation: Paris (city center), on-site with 1 to 2 days WFH\nStart: as soon as you are available\nContract: full-time (CDI)\nCompensation: €100k to €130k + equity (BSPCE)\nYour missions\nAs 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).\nThe role has three layers:\nOwn 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.\n\nManage your squad. Hire, onboard, and grow the engineers in your perimeter. Set the pace, the priorities, and the delivery rhythm.\n\nLead 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.\n\nConcretely, over your first 12 months:\nScale the team with the founders: interviewing, closing, onboarding.\n\nStructure the engineering org: squads, rituals, delivery process, documentation, on-call, and the way we work with product and ops.\n\nShip at scale: the ingestion and anonymization pipeline has to absorb hundreds of company data ecosystems over the next year, reliably and with auditable quality.\n\nSet the technical direction with Thomas: tech choices, design patterns, scalability, security, and infrastructure.\n\nStay hands-on at the start: you code and review in the first months, then step back as the team grows.\n\nWho we're looking for\n10+ years in software engineering, including 3+ years leading engineers as an Engineering Manager, Head of Engineering, VP Eng or CTO.\n\nYou have grown a team from a few people to 15-30 engineers, and you know what breaks along the way: hiring, onboarding, process, architecture.\nStrong technical depth on data-intensive back-end systems: Python, SQL, distributed pipelines, cloud infrastructure (GCP or equivalent). You are still credible in a code review.\n\nA track record of shipping in a demanding, fast-moving environment: start-up or scale-up, ideally from early stage.\nHigh bar on quality and security: we handle our partners' most sensitive data. You care about access control, auditability, and doing things properly.\n\nTeam first, low ego: you lead by clarity and trust, you give hard feedback with kindness, and you make the people around you better.\n\nComfortable working closely with founders, product, and ops in a company where priorities move fast.\nFluent English, mandatory (working language with our clients and the labs).\n\nThe extras that make the difference\nExperience with data engineering at scale: ETL/ELT, orchestration (Airflow, Dagster, etc), warehouses and lakes.\nExperience with data anonymization, privacy, or security-sensitive systems.\nStrong interest in AI, RL environments, and how frontier models are trained.\nTypeScript on the side, for the platform.\nWhy join us\nEntrepreneurial adventure: founding impact, live the early days of an ambitious company at the front line of the AI revolution.\n\nBacked by Y Combinator, join just as we accelerate.\n\nOffices in central Paris.\nPerks: Alan health insurance (mutuelle), 50% Navigo covered.\n\nCompetitive package including bspce.\n\nRecruitment process\nWe move fast.\nA 30 min intro call with Grégoire (co-founder)\nA 60 min deep dive with Thomas (CTO & co-founder): your track record, technical judgment, how you lead\nA leadership case: presented to Thomas and a tech member\nA final fit interview with 2 founders\nReference calls","description_format":"text","description_chars":4716,"description_truncated":false,"requirements":{"experience_years_min":11,"management_years_min":null,"team_size_min":null,"manages_managers":false,"education":null,"security_clearance":false,"languages":[{"language":"English","level":"Advanced (C1)","optional":false}]},"benefits":["Equity","Health insurance"],"hiring_locations":[{"name":"France","iso":"FR","kind":"country"}],"hiring_excludes":[],"relocation_offered":false,"industries":["AI Training Data & Annotation","AI Evaluation & Observability"],"lifecycle":[{"event":"open","at":"2026-09-25T14:05:26Z"}],"visa":[],"liveness":{"score":73,"band":"hot","label":"Hiring now","p_open":1,"p_active":0.81,"p_room":0.9,"age_days":17,"expected_fill_days":30,"reasons":["conf:1","win:mid"],"computed_at":"2026-10-13T05:45:00Z"},"pay":{"stated_usd_annual":145688,"is_top_pay":false},"html_url":"https://alion.io/job/ooak-data-head-of-engineering","json_url":"https://alion.io/job/ooak-data-head-of-engineering.json","meta":{"generated_at":"2026-10-14T02:56:55Z","cache_seconds":300,"methodology":"https://alion.io/methodology","terms":"https://alion.io/terms","contact":"https://alion.io/contact","api":"https://alion.io/developers","about":"Alion is a live layer of people, companies and AI agents: who they are, whether they are real and active right now, what they do and how to work with them, readable by people and by agents and paid per call.","catalog":"https://alion.io/catalog.json","usage":{"tier":"crawler_verified","counted_by":"address","units_charged":1,"used_today":4540,"day_limit":null,"remaining_today":null,"minute_limit":300,"resets_at":"2026-10-15T00:00:00Z"}},"offers":[{"id":"company.slices","title":"One company in depth, by slice","status":"live","price":{"credits":0.02,"usd":0.002,"plus_per_slice":{"credits":0.05,"usd":0.005}},"unit":"per company, plus each slice with data","note":"the employer in depth","call":{"mcp_tool":"get_company","arguments":{"id":2066},"rest":"https://alion.io/mcp/rest/get_company?id=2066"},"human":"https://alion.io/catalog?offer=company.slices&for=job%2Fooak-data-head-of-engineering"},{"id":"market.stats","title":"A market slice: pay, demand and time to fill","status":"live","price":{"credits":1,"usd":0.1},"unit":"per slice","note":"pay, demand and time to fill for this role and place","call":{"mcp_tool":"market_stats"},"human":"https://alion.io/catalog?offer=market.stats&for=job%2Fooak-data-head-of-engineering"},{"id":"job.search","title":"Open jobs by role, technology, place, pay and visa","status":"live","price":{"credits":0.02,"usd":0.002},"unit":"per posting in a list","note":"similar open postings","call":{"mcp_tool":"search_jobs"},"human":"https://alion.io/catalog?offer=job.search&for=job%2Fooak-data-head-of-engineering"},{"id":"company.verify","title":"Is this company real and active right now","status":"pilot","price":null,"unit":"per company","request":{"url":"https://alion.io/catalog/request","method":"POST","body":"{\"offer\": \"company.verify\", \"for\": \"job/ooak-data-head-of-engineering\", \"note\": \"what you need it for\"}"},"human":"https://alion.io/catalog?offer=company.verify&for=job%2Fooak-data-head-of-engineering"}]}
