Software Engineer, CAD Automation

ABOUT US Reframe Systems is a Physical AI and robotics company on a mission to make high-performance housing attainable and abundant in the communities where people want to live. Through our vertically integrated delivery model and highly automated microfactories, we deliver climate resilient homes and buildings with greater speed and predictability than traditional construction. Our volumetric modular buildings are produced in our Andover, MA microfactory, with a growing pipeline across North America and a new microfactory on the way. We are building a system that balances repeatability with site-responsive design, enabling homes that are adaptable to each site, community, and customer need. Our cross-disciplinary team brings together architecture, robotics, design engineering, software, factory operations, and field delivery to change how housing gets delivered. We’re reimagining the future of housing through a smarter and more sustainable system that empowers people to live better. Come build it with us. WHAT WE'RE LOOKING FOR Our mission hinges on being able to create building designs with 10x more detail than typical architectural sets in 1/10th the time. We're looking for the software engineer to build the CAD automations that power that workflow. You'll write custom features in and around Onshape (FeatureScript and API driven), and back them with real engineering practices, so the tools you ship run reliably in production and take repeated manual work off the team's plate. Your work sits downstream of architectural design and feeds our CAD-to-fab pipeline all the way to the factory floor. This is a hands-on role. The best candidate is a software engineer who enjoys living in CAD and learning new domains. You're comfortable using coding agents and modern AI tooling to prototype fast, work closely with the team, and ship something people actually use day to day rather than a demo that never leaves the shelf. KEY RESPONSIBILITIES - Design, develop, and maintain custom Onshape features in FeatureScript that run in production and hold up to daily use. - Augment Onshape workflows by building out tooling and integrating with systems outside of Onshape via Onshape APIs. - Expanding the capabilities and uses (skills) of our modeling MCP built on top of Onshape APIs - Work with the design engineering team to find repeated manual work, prototype a solution, and get it into their daily workflow. - Build automation that integrates MEP constraints and augments device and fixture placement. - Build automated code-compliance checking, e.g. outlet placement, egress, tempered windows requirements. - Collaborate with interdisciplinary teams to raise efficiency and throughput across design and manufacturing. QUALIFICATIONS Prior knowledge or experience in architecture or construction is not required. We'll get you up to speed. - BS in computer science or electrical engineering, or equivalent experience. - 2+ years of general software engineering experience, ideally in Go, Python, C#, including automated testing, CI/CD, monitoring and alerting, debugging and root cause analysis. - Hands-on experience with parametric design (Onshape, Autodesk Fusion, SolidWorks, etc.) and building custom features/plugins/extensions in that platform. Experience outside of work is great! - Experience using coding agents to build prototypes, work with others, and get to a solution quickly. A 0-to-1 builder. NICE TO HAVE - Experience with Onshape and building custom features in Onshape with FeatureScript, used in a production setting. - Experience with the Onshape API or building integrations and apps beyond FeatureScript. - Experience in a manufacturing, DFMA, or hardware product setting. - Familiarity with CAD-to
