Job summary

sizeless is building the data layer for the infrastructure under our streets. A small ETH Zürich–founded team is looking for engineers who want to ship real products to paying customers from Zürich.

You will contribute across the stack, from field capture apps to the analytics workspace, and help manage large 3D data pipelines. The role emphasizes ownership, fast learning, and collaboration with founders in a modern, AI-first toolchain.

Qualifications

• Solid engineering fundamentals in TypeScript and/or Python.
• Comfortable moving between product code and infrastructure.
• Experience or interest in AI-assisted development and modern toolchains.

Responsibilities

• Build the product our customers use: the capture app in the field and the workspace where results are delivered.

Job description

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.

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
