Senior Mechanical Engineer

Job Description

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 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
- ---------------------

We are looking for a **Senior Mechanical Engineer** who thrives at the intersection of rigorous design and physical reality. You will help drive Reframe's factory vision at the system level, then translate it into execution at **FAB1** (our first microfactory) by building and standardizing the mechanical, robotics, and automation building blocks we will replicate across future factories.

This is a role for someone that loves both designing robust, detailed mechanical systems, then getting into the shop, helping build, test, and deploy production hardware. We need a hands-on technical leader who is excited to be "in the trenches"---assembling equipment, troubleshooting on the floor, and validating designs in real-time. You will bring a high level of engineering discipline to our team, specifically driving standards in **GD\&T** , **detailed drawing generation** , and **structural analysis (FEA)**. You will bridge the gap between R\&D concepts and robust, industrial-grade reliability.

Responsibilities
- ---------------

* **Help Lead FAB1 Commissioning:** Take ownership of key mechanical subsystems during the factory launch. Troubleshoot assembly issues, oversee equipment installation, and validate system performance against requirements.

* **High-Fidelity Design \& Documentation:** Create complex 2D technical drawings for fabrication and assembly. You will be the internal standard-bearer for GD\&T (ASME Y14.5), ensuring parts are manufactured to tolerance and fit the first time.

* **Structural Analysis (FEA):** Perform Finite Element Analysis on fixtures, gantries, and end-effectors to ensure safety factors and structural rigidity meet industrial standards before fabrication.

* **Detailed Mechanical Design:** Design robust mechanical systems using **Onshape**, from large weldments and safety enclosures to precision grippers and fixtures.

* **Vendor \& Fabrication Management:** Liaise with external machine shops and vendors. Your detailed drawing packages will be the primary communication tool to ensure external partners deliver quality parts on schedule.

* **Root Cause Analysis:** When things break (and they will), lead the investigation. Use data and physical inspection to identify failure modes and implement permanent engineering fixes.

* **Mentorship:** Act as a technical mentor to junior engineers, modeling best practices in design review, documentation, and safety.

Qualifications
- -------------

* **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:** You can read, write, and explain geometric dimensioning and tolerancing to ensure 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:** You are comfortable using hand tools, power tools, and basic shop equipment (mills, lathes, etc.) to modify parts or build prototypes.

Nice to Have
- -----------

* 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.

**Please include a portfolio or examples of previous work (specifically highlighting drawing packages or complex mechanisms) with your application.**
