Résumé du poste

1zu100 is automating construction planning and building plans as a service. We seek a founding engineer to craft the AI stack that plans large residential buildings end to end. You’ll work with a small, high-agency team on real projects that ship immediately.

You will own harness engineering, data/context translation, eval harnesses, and BIM/IFC automation, collaborating closely with founders to deliver robust, scalable solutions in a fast-growing startup.

Qualifications

• Hands-on experience with harness engineering: agents, tool orchestration, evals.
• High agency and an entrepreneurial drive; founding experience is a plus.
• Nice to have: German, Revit, IFC or Grasshopper, RLHF or diffusion models.

Responsabilités

• Harness engineering: build and run the layer around the model end to end, including memory, tool orchestration, verification, drawing and document generation.
• Data and context: convert planning data (CAD/BIM, PDFs, surveys, codes) into traceable context.
• Evals and benchmarks: create eval harness and measure agents against architectural rule sets.
• BIM and IFC automation: connect to architect's toolchain to drive automated modeling and interoperability.

Description du poste

1zu100 is automating construction planning. Together with exceptional architecture firms, we plan multi-unit residential buildings and deliver completed, permitted plans as a service.

TL;DR

We are looking for one cracked founding engineer to build the AI that plans large residential buildings end to end: the agent harness, the data and context layer, and the evals. You work in a small, high-agency team on real projects that ship right away.

Your role

Harness engineering: You build and run the layer around the model end to end: memory, tool orchestration, verification, drawing and document generation, so the output stays consistent and code-compliant at scale.

Data and context: You turn messy planning data (CAD/BIM models, PDFs, site surveys, building codes) into the right context at every phase, always traceable back to its source.

Evals and benchmarks: You build the eval harness (datasets, regression tests) and measure our agents against the architectural rule sets and judgment calls.

BIM and IFC automation: You connect to the architect's toolchain (Revit, ArchiCAD, IFC) to drive automated modeling and clean interoperability.

Your profile

Hands-on experience with harness engineering: agents, tool orchestration, evals.

High agency and an entrepreneurial drive. Ideally, you have founded before or want to. You find the work yourself and move fast.

Experience in a high-growth environment (startup, scale-up or similar).

Nice to have: German, Revit, IFC or Grasshopper, a non-linear CV and experiments with reinforcement learning (MCTS, GRPO, RLHF) or diffusion models (discrete and continuous).

What we offer

A fast-paced environment at a fast-growing startup, with a steep learning curve

Competitive salary and a stake in the company, with first-hire upside

Real projects that ship right away

You build right alongside the founders, in the same codebase on the same hard problems

Wellpass and unlimited coffee from a professional barista

We're a small team with an extremely high bar. If you want to work deeply on hard problems and change the way construction planning is done, you're the one we need.
