ABOUT REFRAME Reframe Systems is building software-driven microfactories that produce high-quality, net-zero homes at a fraction of the cost and time of conventional construction. Our Pixels-to-Parts platform connects design intent directly to factory execution, enabling mass-customized housing built with manufacturing rigor. We are a ~70-person team backed by leading investors, with homes in production today and a growing project pipeline. THE ROLE The Building Systems team owns the definition of Reframe's repeatable building system: the standard assemblies, details, components, and interfaces that every project draws from, so project teams can move fast on decisions that have already been made well once. As a Building Systems Engineer, you will define, document, prototype, and continuously improve that system. Your work is deliberately decoupled from day-to-day project execution: your job is to make the next ten projects easier, not to ship this month's modules. Over the next 12 months our product focus is Type 5 low-rise residential (single-family homes, ADUs, and townhomes), and you will help lock in the layered system of standards that supports shared components across those product types. WHAT YOU'LL DO - Define and maintain the standard assemblies and details that make up our building system: structural and envelope recipes, exterior wall assemblies, mate lines, floor cassettes, connection methods, and the interfaces between them - Decide where variation is allowed and where the system is frozen, and track project-specific deviations so exceptions are explicit and time-bound rather than tribal knowledge - Own system-level subsystems end to end, such as the MEPF module interconnect system (circuits, plumbing, and ductwork connections between finished modules) and a scalable electrical system, from research through prototyping with the factory floor to a defined standard detail set - Lead high-impact system optimization initiatives such as enclosed wall panels,
