Staff Software Engineer, Pixels to Parts

What We're Looking for

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.

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.

Key Responsibilities

• Help architect and build the core of our design automation platform: turn a floor plan into manufacturing-ready building design.
• Turn our building system’s design decisions into a library of programmatic checks. Each one validates a model against hard dimensional, code and manufacturing constraints, and explains a failure by pointing to the rule behind it.
• Build agentic workflows: tool-using agents, MCP servers, and retrieval over our design and product data
• Develop evals and guardrails that check model outputs against hard physical, code and manufacturing constraints
• Write deterministic, well-tested code that generates geometry, parts lists and manufacturing data from a design
• Help build the visualization layer so designers, customers and the factory can see and verify a design
• Deploy and operate what you build in the cloud: containers, infrastructure as code, CI/CD and observability
• Work closely with Architecture, Design Engineering, DFMA (design for manufacturing and assembly) and Factory Operations. Learn how buildings are designed and built, including on the factory floor.
• Improve our engineering practices, tooling and developer experience as the team grows

Qualifications

• 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
• Able to work on-site in Billerica, MA at least 2 days a week
• Bonus: Exposure to manufacturing, robotics, hardware or other systems where software meets the physical world is a plus. No CAD, BIM or architecture experience required
