About the role
You'll build the backend APIs and mathematical core of our design engine, developing optimisation models, geometric algorithms, and simulation systems that translate extracted plan information into physically valid, optimised 3D building structures — all while capturing the real-world constraints of residential construction and serving these models to our applications. Your work will power the engine that turns drawings into buildable designs.

What you'll do
- Build APIs and services to provide conduction design models to frontend applications using Python and FastAPI.
- Design and implement optimization models using operations research techniques including constrained programming, linear programming, and mixed-integer programming (MIP)
- Develop computational geometry systems that convert plan-derived data into structured 3D building representations
- Build simulation and constraint systems that model real-world construction rules, structural relationships, and material layouts




- Develop production-grade Python systems that solve large-scale optimization and geometric problems
- Improve performance and scalability of heavy mathematical workloads through algorithm design, solver tuning, and profiling
- Work closely with ML engineers and platform engineers to integrate optimization systems into the broader plan ingestion and design pipeline
- Ensure mathematical systems are reliable, testable, maintainable, and production-ready

Qualifications
- 6+ years of experience developing mathematical or optimization systems in production environments
- Expert Python programming skills with experience building complex numerical or algorithmic systems
- Robust background in operations research, constrained optimization, linear programming, or mixed-integer programming
- Strong understanding of algorithm design, computational complexity, and performance optimization
- Experience implementing or working with computational geometry algorithms
- Comfortable working
