Location: Belgium / Europe (Hybrid or On-site in Sint-Truiden)Stage: Seed → Series AIndustry: Construction Tech / Aerial Data / SaaSAbout AirocollectAirocollect 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.Key ResponsibilitiesPhotogrammetry, 3D & Geospatial SystemsDevelop and improve photogrammetry and point‑cloud processing pipelinesProcess and analyze LiDAR data and governmental geoservice point cloudsResearch, integrate, and optimize open‑source photogrammetry and geometry toolsWork on 3D visualization pipelines using Three.jsEnsure accurate handling of geospatial data, projections, and coordinate systems (EPSG)AI / ML & Algorithm DevelopmentDesign and improve AI/ML models for automatic roof detection and measurement (roof planes, hips, gutters, valleys, etc.)Implement and optimize: Feature extraction from spatial and point‑cloud data, Geometry fitting algorithms (e.g. polyfit) and Random Forest–based classifiers and similar models.Technical Leadership & ArchitectureScale and own the long‑term technical architecture for a scalable SaaS platformDesign systems that balance performance, accuracy, scalability, and speed of executionContribute hands‑on to core codebases where technical depth is criticalTranslate customer and business needs into technical solutionsMaintain high standards for code quality, testing, and performanceTeam Building & CultureHire, mentor, and lead a high‑performing engineering teamBuild a pragmatic, ownership‑driven engineering cultureRequired Technical SkillsPythonNode.jsC++Angular / TypeScriptMongoDBPoint clouds & 3D data processingThree.jsGeospatial data, maps & coordinate systems (EPSG, projections)AI / ML modelsExperience or Familiarity WithPhotogrammetry toolsLiDAR data processingImage processing & computer visionResearch‑oriented problem solving and algorithm evaluationNice to HaveExperience in roof modelling or construction‑related dataKnowledge of cloud‑based processing pipelinesContributions to open‑source projectsWho We’re Looking ForSenior technical leader with hands‑on experience in complex data‑heavy systemsComfortable operating in a Seed → Series A startup environmentStrong balance between deep technical expertise and product thinkingAble to lead by example while still writing and reviewing critical codeClear communicator who can explain complex systems to non‑technical stakeholdersAanbodWhat We OfferFounding‑level impact on product and technical directionOwnership of core algorithms and platform architectureA real‑world product solving complex problems in a traditional industryA fast‑moving, ambitious team building for scale
