Job detail for Software Engineer

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
