Senior Design Engineer

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 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.

We are seeking a highly talented, detail-oriented, and experienced Design Engineer to join our dynamic and multidisciplinary AEC team. This role is crucial for transforming the traditional design process by developing and implementing advanced parameterized designs and automated design logic for residential and low-rise multi-family buildings.

The right candidate will serve as a technical leader, bridging the gap between design ideation and final fabrication. You will leverage deep expertise in parametric CAD to create designs that are far more detailed than traditional AEC workflows, generate manufacturing-ready assets, and ultimately drive efficiency and precision across our product line. The ideal candidate will thrive in a fast-paced environment and be comfortable owning the end-to-end design-to-manufacturing process.

The position reports to the Design Engineering Team Lead. The position is full-time, salaried, exempt, and in-person.

As a Senior Mechanical Engineer, you will be responsible for the following areas, with an emphasis on automation and process improvement:

• Expert CAD Modeling and Detailing: Serve as the technical authority for creating detailed and parameterized CAD models using Onshape. Collaborate with the architecture and manufacturing teams to convert high-level concepts into robust, fabrication-ready digital models with a high level of accuracy and a deep understanding of tolerance stackup.

• Advanced CAD version Management: Establish, organize, and maintain best practices for 3D model management, file structure, documentation and revision control, ensuring models are seamlessly integrated into the fabrication pipeline.

• Cross-Functional Collaboration: Act as a critical technical interface, collaborating effectively with manufacturing, operations, architecture, and software teams to resolve design challenges and meet critical product development deadlines.

• Conceptualization & Ideation: Lead the generation of mechanical concepts, feasibility studies for standardized and parametric assemblies, and initial architecture development based on product requirements, collaborating closely with product management and industrial design teams.

• Prototyping & Testing: Design, build, and iterate on functional prototypes; develop and execute rigorous testing plans (e.g., DVT - Design Verification Testing) to validate mechanical performance, durability, and compliance with specifications.

• 7+ years of progressive experience as a Mechanical Engineer or a similar role focused on detailed product design, preferably within the AEC, high-tech manufacturing, or related construction industries.

• Bachelor's degree in Mechanical Engineering, Manufacturing Engineering, Process Engineering, Architecture or a closely related technical field.

• Expert-level proficiency in a major parametric CAD system (e.g., Onshape, SolidWorks, CATIA).

• Demonstrated experience with the management of large-scale, complex 3D assemblies and data management.

• Proven ability to proactively identify, diagnose, and solve complex, multidisciplinary engineering problems.

• Exceptional attention to detail and a commitment to producing accurate, precise, and manufacturing-ready models and documentation.

• Ability to mentor junior team members on best practices in modeling and documentation.
