Résumé du poste

1zu100 is automating construction planning and delivering completed, permitted plans as a service. We seek a founding engineer to build the AI that plans large residential buildings end to end, handling memory, tool orchestration, verification, drawing, and document generation.

The role focuses on turning messy planning data into traceable context, establishing eval datasets and benchmarks, and integrating BIM/IFC workflows with Revit, ArchiCAD and IFC-enabled pipelines.

Qualifications

• Hands-on experience with harness engineering: agents, tool orchestration, evals.
• High agency and an entrepreneurial drive; ideally have founded before or want to.
• Experience in a high-growth environment (startup, scale-up or similar).
• Nice to have: German, Revit, IFC or Grasshopper, reinforcement learning or diffusion models.

Responsabilités

• Harness engineering: build and run the layer around the model end to end, memory, tool orchestration, verification, drawing and document generation.
• Data and context: convert CAD/BIM models, PDFs, surveys and codes into traceable, source-backed context.
• Evals and benchmarks: create eval harnesses and measure against architectural rules.
• BIM and IFC automation: connect to Revit, ArchiCAD, IFC to drive automated modeling and interoperability.

Description du poste

Build the future of architecture

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.

How we hire

1. An intro call with the founders.

2. A technical interview.

3. A trial day on-site in Munich. We pick a problem together and build it side by side.

We care about who you are, not just what's on your CV.
