sizeless is building the data layer for the infrastructure under our streets. A construction crew films an open trench with a phone, and our system turns that recording into a 3D model, recognises what is in the ground, and produces the documentation the industry needs – CAD, BIM, GIS and quantities – in a fraction of the time it takes today.
It is a real problem with real customers: construction and utilities still document reality by hand, and almost nothing about that process has changed in decades. We are a small technical team founded out of ETH Zürich, and we are looking for engineers who want to build the systems that make this work in production.
Tasks
- Build the product our customers use: the capture app in the field and the workspace where results are delivered
- Work across the stack - web, mobile, backend and the data pipelines behind them
- Keep the processing side reliable: long-running jobs, large files, and a lot of 3D data moving between systems
- Build the internal tooling the rest of the team depends on
Requirements
- Solid engineering fundamentals in TypeScript, Python or a comparable language
- Comfortable moving between product code and infrastructure
- Real leverage from AI-assisted development, whatever your setup
- Ownership: you take problems personally and see them through
- Full working proficiency in English; German is a plus, not a requirement
Experience with 3D data, mobile apps or geospatial systems is welcome, but not a requirement. We care more that you learn quickly and take details seriously.
If you are unsure whether you tick every box, apply anyway — tell us what you have built.
Benefits
- Early team member with real ownership – your work ships to paying customers, not a demo
- Employee stock options: you own part of what you build
- New office in Zürich Kreis 5
- Modern, AI-first toolchain – we invest in whatever makes you faster
- Work directly with the founders
