Head of Data Platform / DevOps - Full-time Position

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)
