Senior Machine Learning/Software Architect (PropTech)

Freelance Senior ML / Software Architect – PropTech

Remote-First within DACH / Europe | Start mid-May

🚀 About the Role

Architect a novel computer vision pipeline — from blank canvas to production — for a stealth-mode real estate tech startup.

Architect a novel computer vision pipeline — from blank canvas to production — for a stealth-mode real estate tech startup building something that hasn't been built before.

A PropTech startup operating in the DACH region is tackling a genuinely unsolved problem at the intersection of computer vision, architectural data, and 3D reconstruction.

The technical challenge: automatically processing high-quality technical drawings — architectural schematics, engineering blueprints — using computer vision. This is a greenfield build

🛠️ What You’ll Do

• Architect the CV Pipeline End-to-End: Design and build a novel computer vision system capable of processing architectural and engineering drawings — classification, segmentation, multi-class recognition, and cross-drawing relationship modelling.
• Lead 3D Reconstruction Integration: Define how CV outputs feed into a downstream 3D model reconstruction pipeline, owning the interface design and data flow between stages.

• Act as Technical Co-Lead: Work directly with the founder as a close architectural partner and sounding board. High trust, high autonomy — you shape the decisions, not just implement them.
• Own Stack and Tooling Decisions: Drive Python-based pipeline architecture with an eye toward future Rust deployment. Make defensible technology choices with long-term scalability in mind.

✅ What you bring

• Deep hands-on experience with image segmentation, object detection, and multi-class classification — ideally on complex, non-standard visual inputs (technical drawings, schematics, or similar)
• Track record designing and shipping production-grade ML pipelines end-to-end — not just notebooks
• Strong Python fluency across the ML stack: PyTorch or JAX, relevant CV libraries, data pipeline tooling
• Comfortable making high-stakes architectural decisions with incomplete information in an early-stage environment
• Ideally German speaking and fluent in English

🚀 Valued

• Experience with technical document understanding (CAD, BIM, blueprint parsing)
• Background in 3D reconstruction, point clouds, or related spatial ML
• Familiarity with Rust, or genuine interest in owning the deployment layer down the line
• Prior experience as a founding engineer or early technical hire
• PropTech, AEC (Architecture, Engineering, Construction), or geospatial background

🎯 Location and Start

This is a fully remote role, ideally based in the DACH region or a compatible time zone. The start date is mid or end of May.

We welcome applications regardless of gender, background, age, religion, sexual orientation, or disability.
