Staff Software Engineer, Pixels to Parts

Required

• Your mission is to help build the next generation of our Pixels-to-Parts system: the software that turns a design, a floor plan and configurations, into every part our microfactory needs to build a home. Here's a somewhat recent talk from Ethan Keller, the tech lead for the Pixels-to-Parts team, showing what the system can do (as of Nov 2025):
• We are seeking a software engineer to build the agentic workflows that interpret intent and the deterministic code that turns a design into exact geometry, parts and visualizations. You don't need CAD or architecture experience; we'd rather you question decades-old assumptions about design software and rebuild the stack from first principles, learning the domain alongside people who know buildings and manufacturing well. If you're a strong generalist who enjoys breaking down fuzzy problems, shipping, and seeing your code have real world impact (in this case, houses and apartments), this is your platform.
• Degree in Computer Science, Electrical Engineering, or a related quantitative field is preferred; equivalent experience is welcome
• 5+ years building production software, with Python as a primary language
• Experience shipping cloud-native software (containers, managed services, infrastructure as code, CI/CD)
• Strong interest in agentic systems, shown through work or side projects, e.g., MCP servers, RAG pipelines, LangGraph or similar frameworks, tool-calling agents, LLM evals. Production experience is a significant plus
• Comfort with the math and algorithms behind your code (geometry, linear algebra, graphs or optimization)
• A generalist's range: comfortable moving between backend, data, infrastructure and some frontend as the problem requires
• Experience setting technical direction for a system or team
• Track record of mentoring engineers and raising the bar on engineering practices.
• Ability to navigate ambiguity. You work effectively under deadlines and shifting priorities while maintaining quality and accountability
• Clear written and verbal communication, and a hands-on, "no fences" approach to collaboration
