Job Summary:

The HyLighter collect high-value datasets (LiDAR, imagery, methane) to help utilities and infrastructure operators maintain their assets with lower cost and carbon impact. We are now building the data platform that transforms this raw sensor data into actionable insights for our clients.

As Head of Data Platform / Tech Lead, you will be the technical leader responsible for designing, building, and securing this platform end-to-end: from ingestion pipelines to geospatial storage, processing, visualization, and client delivery. You will work hands-on with cloud services, open-source geospatial libraries, and lead the small team that will grow around you.

The Mission:

Under the guidance of our CTO and in collaboration with the technical and regulatory teams, your responsibilities will include:

Architecture & Foundations

• Define the technical architecture of our data platform (storage, processing, databases, APIs, client portal).
• Ensure scalability, cost efficiency, and robustness from MVP to production.

Data Engineering

• Design and implement workflows for LiDAR (PDAL), imagery (photogrammetry), and methane analytics.
• Structure storage and metadata catalogs (STAC, PostGIS/Timescale, or equivalent).
• Enable fast visualization formats (COG, EPT, 3D Tiles or equivalent) for client portal use.

Security & Compliance

• Implement best practices: access control (RBAC/SSO), encryption, audit logging.
• Prepare the company toward SOC 2 / ISO 27001 readiness.

Profile Sought:

Education: MSc (PhD) in Computer Science, Geoinformatics, Data Engineering, or equivalent practical experience. 5+ years in software/data engineering, with at least 2 years leading teams or projects. Track record of delivering geospatial or data platforms used by external clients at scale

We are looking for an ambitious and highly motivated person to join our team, participate in building HyLight, and grow with the project!

Technical Skills:

This is an exhaustive list of sought after skills, if you have

• Cloud architecture: designing scalable storage, compute, and API layers across major cloud providers.
• Geospatial: PostGIS, PDAL, raster/vector tiling (COG, EPT, Cesium, titiler).
• Backend & APIs: Python (FastAPI), Node.js (NestJS), containerization (Docker, Kubernetes/containers).
• Security: RBAC/SSO (Auth0, Cognito, Okta, etc.), encryption, audit logging, SOC 2/GDPR familiarity.
• CI/CD & IaC: Terraform, Pulumi, or equivalent; GitHub Actions or similar.

Soft Skills:

• Strong sense of ownership, ability to go from architecture to hands-on coding.
• Excellent communication: can explain complex systems simply to business stakeholders.
• Leadership mindset: mentoring and structuring a growing engineering team.
• Startup DNA: pragmatic, resourceful, not afraid of building v1 quickly and iterating.

Languages:

French (professional working proficiency), English (fluent – internal communication and documentation)

What We Offer:

• Annual compensation: €50,000 - €70,000 (based on experience)
• Real responsibility and direct impact on cutting-edge autonomous flight technology
• Mentorship with the Tech and Regulatory teams
• Potential to become a shareholder in HyLight
• 100% reimbursement of public transport pass (Navigo) or €800/year for sustainable commuting
• Bike provided for commuting
• Free lunch
• Bi-annual offsite trips with the whole team
• Excellent work environment: international team, team events, beautiful offices on a former airbase

Why You Should Join:

• Founder Mentality: We value extreme ownership and want people who think like founders—fast decision makers, natural problem solvers, and executers.
• Ground Floor Opportunity: You’ll be helping to shape and grow a revolutionary company with the resources to back it.
• Impact & Speed: Work in a fast-paced environment where your contributions will have immediate, tangible effects on the company’s success.

Location:

• Office : Base 217, Brétigny-sur-Orge, accessible via RER C.
• Lab and Warehouse access
• You’ll work side-by-side with experts in embedded, aerospace, and hydrogen propulsion systems—where your impact matters from day one.
