Strong Python fundamentals and experience building non-trivial software or numerical projects

Coursework or practical experience in operations research, optimization, algorithms, numerical methods, or a closely related field

Understanding of core data structures, algorithms, and computational complexity

Some exposure to computational geometry, geometric modeling, simulation, or spatial algorithms

Familiarity with Linux and Git, with a willingness to learn production development and deployment practices

You take ownership of well-scoped tasks while knowing when to ask for guidance

You enjoy translating messy real-world rules into clear logic, algorithms, or mathematical formulations

You care about correctness, readability, and understanding why a system behaves the way it does

You are eager to learn from experienced engineers and steadily take on more responsibility

You communicate clearly and collaborate well with engineers across disciplines

Experience with OR solvers such as Gurobi, CPLEX, SCIP, or OR-Tools

Academic, internship, or personal project experience in computational geometry, geometric modeling, or spatial algorithms

Experience building APIs with FastAPI or another Python web framework

Exposure to profiling, numerical performance optimization, or simulation workloads

Familiarity with the construction, CAD, manufacturing, robotics, or engineering domains

Benchmark (formerly BotBuilt, Y Combinator W21) is building the next generation of technology behind American homebuilding. We’re starting with one of the hardest parts of the stack: reliably turning messy, real-world construction plans into structured, usable data.

Our systems translate architectural drawings into detailed digital representations of homes — including framing systems, materials, and structural components — that can drive downstream automation, analysis, and construction workflows.
