Founding engineer, AI on CAD geometry (co-founder equity)

Founding engineer: AI that reads mechanical designs (Berlin / remote EU): LoopforgeLab enables machine and hardware makers make better design decisions by better we mean shorter design iterations, more sustainable products with less cost to manfuacture and own. We are building the Forge Engine is an agentic tool for manufacturing. Give it a BOM and a STEP file and it returns what the part costs to make and what the machine will cost to own over fifteen years, while there is still time to change the design. The lifecycle engine is built and runs on declared drivers. The agent already modifies geometry from natural-language instructions on our platform. The next piece is the reason we are hiring. We need geometry reasoning that holds up on real customer CAD: feature recognition from B-rep, tolerances read per feature rather than per part, similarity against parts we have already costed, and an evaluation setup that shows whether the agent is improving or only sounding more certain. Also we need to build integrations with different CAD/ER and PLM systems. What you would own: The geometry reasoning module. Feature extraction from STEP, manufacturability signals, tolerance and surface finish handling. The design agent’s optimisation loop. Iterating a design against a cost or lifecycle target rather than following instructions. Evaluation. Benchmarks, regression suites, and the discipline to drop approaches that do not beat the baseline. Architecture decisions with the founder,
