Senior Mechanical Engineer

Reframe Systems • Andover, MA

34d • Onsite

About The Position

Reframe Systems is a Physical AI and robotics company focused on making high-performance housing attainable and abundant. We utilize a vertically integrated delivery model and highly automated microfactories to produce climate-resilient homes and buildings with greater speed and predictability than traditional construction. Our volumetric modular buildings are manufactured in our Andover, MA microfactory, with plans for expansion across North America. We are building a system that balances repeatability with site-responsive design, allowing for adaptable homes. Our team comprises experts in architecture, robotics, design engineering, software, factory operations, and field delivery, all dedicated to transforming housing delivery. We are seeking a Senior Mechanical Engineer who excels at the intersection of rigorous design and physical reality. This role will drive Reframe’s factory vision at the system level and translate it into execution at FAB1, our first microfactory. You will build and standardize the mechanical, robotics, and automation components for replication in future factories. The ideal candidate is passionate about designing robust, detailed mechanical systems and is equally comfortable in the shop, assisting with building, testing, and deploying production hardware. We need a hands-on technical leader who is eager to be involved in assembling equipment, troubleshooting on the factory floor, and validating designs in real-time. You will bring a high level of engineering discipline, focusing on standards in GD&T, detailed drawing generation, and structural analysis (FEA), bridging the gap between R&D concepts and industrial-grade reliability.

Requirements

• BS or MS in Mechanical Engineering or a related technical field.
• 5+ years of experience in machine design, industrial automation, or heavy equipment engineering.
• Expert-level CAD skills (Onshape preferred) with a portfolio demonstrating complex assembly management.
• Strong proficiency in GD&T: ability to read, write, and explain geometric dimensioning and tolerancing for manufacturability and inspectability.
• Simulation experience: practical experience using FEA (Ansys, SolidWorks Sim, or cloud-native tools) to validate structural loads and deflection.
• Commissioning experience: proven track record of bringing hardware from the design phase to full operation in a factory or industrial setting.
• Hands-on capability: comfort using hand tools, power tools, and basic shop equipment (mills, lathes, etc.) to modify parts or build prototypes.

Nice To Haves

• Experience with large-scale gantry systems or robotic workcells.
• Background in the construction, automotive, or aerospace industries.
• Experience designing welding fixtures or heavy-duty material handling equipment.
• Familiarity with PDM/PLM systems and version control in a fast-paced environment.
• Inclusion of a portfolio or examples of previous work (specifically highlighting drawing packages or complex mechanisms) with the application.

Responsibilities

• Take ownership of key mechanical subsystems during the factory launch, troubleshooting assembly issues, overseeing equipment installation, and validating system performance against requirements.
• Create complex 2D technical drawings for fabrication and assembly, serving as the internal standard-bearer for GD&T (ASME Y14.5) to ensure parts are manufactured to tolerance and fit correctly.
• Perform Finite Element Analysis (FEA) on fixtures, gantries, and end-effectors to ensure safety factors and structural rigidity meet industrial standards before fabrication.
• Design robust mechanical systems using Onshape, ranging from large weldments and safety enclosures to precision grippers and fixtures.
• Liaise with external machine shops and vendors, using detailed drawing packages as the primary communication tool to ensure quality parts are delivered on schedule.
• Lead investigations into equipment failures, using data and physical inspection to identify failure modes and implement permanent engineering fixes.
• Act as a technical mentor to junior engineers, modeling best practices in design review, documentation, and safety.
