AI/Data Engineering Manager (F/H)

Context: Lighthouse is becoming a full product team. You join Bertrand’s team (VP Engineering), working directly with our CEO and hand in hand with a dedicated Product Manager. You manage 2 Senior AI Software Engineer, with a third hire on the way, target of 3 to 4 engineers. The team is shielded from run work and focuses on the AI product.

The Goal: Ship the 3 AI features on the roadmap to production within 12 months, one per persona, on data foundations ready for our 700 sites.

Key Challenges:

• Player-coach leadership: You split your time between leading and building. You build pipelines and features yourself and pair with the team, while coaching, setting standards and hiring.

• Knock down the first dominoes: You take the Problem Solving Coach from POC to production, then launch data synthesis for managers and AI analytics for leadership. The agentic stack is built from scratch in TypeScript on Deno, with frontier models through AWS Bedrock.

• Data foundations: You design and build resilient, well-governed ETL/ELT pipelines on shop-floor data, so that each building block makes the next feature easier to build.

• Co-build and roadmap: You deliver our first co-build, which tailors our features and lays the groundwork for a multi-site steering tool for leadership. With your PM, you fully shape the roadmap: the foundations are solid and much is still to be decided.Must-haves:

• Experience: 5 to 8 years in data engineering or data analytics, including at least 1 to 2 years managing a team (feedback, growth, hiring).

• Pipelines in production: You have designed and run data pipelines (ETL/ELT) in production, with real stakes around quality, resilience and governance.

• Data for AI: You have contributed to AI features in production, on data preparation, evaluation or integration into an existing product.

• Hands-on every day: You still build regularly (SQL, Python, pipelines), use AI every day in your work, and are comfortable with pair programming and TDD.

Nice to have: These skills remain optional.

• Experience fine-tuning or deploying open-weight models in production.
• Some software development experience, ideally in TypeScript, the language of our stack.
