About Airocollect

Airocollect is a fast-growing Construction Tech startup making aerial data accessible to roofing and construction professionals. Our SaaS platform transforms drone imagery, LiDAR, and geospatial data into clear, actionable insights—without requiring a pilot license or complex workflows. Already trusted by leading construction companies across Europe, we are preparing for our next growth phase: scaling product, infrastructure, and technical depth toward Series A.
To support this journey, we are looking for a hands‑on Lead Developer with deep technical expertise in 3D data, photogrammetry, and geospatial systems, combined with strong product and leadership instincts. You will own the entire technical function at Airocollect: architecture, engineering execution, data pipelines, and technical strategy.

This is a builder‑first role.

You will actively contribute to core algorithms and systems while shaping the team, roadmap, and long‑term technical vision. You will work closely with the founders, product, and commercial teams to turn complex spatial data into a simple, scalable SaaS product.
