Founding Engineer

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

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.

• 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 architects toolchain (Revit ArchiCAD IFC) to drive automated modeling and clean interoperability.

• 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).

• 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

Were 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 youre the one we need.

1. Apply here.

2. An intro call with the founders.

3. A technical interview.

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

If youre drawn to what were building but dont meet every requirement we still want to hear from you. Studies show that women in particular tend to apply only when they meet 100% of the criteria. If thats you please dont let that hold you back. Wed love to receive your application.
