Engineering Technician

About the Company

Mesodyne builds compact, silent thermophotovoltaic generators — MIT-born LightCell tech that runs on any fuel and lasts 10x longer than batteries or engines. We serve industrial and defense customers with active contracts and a growing pipeline.

About the Role

As an Engineering Technician at Mesodyne, you'll work closely with our engineering team to build, test, and refine hardware — from custom jigs and fixtures to production and test setups. You'll run a wide range of fabrication and joining processes, keep our equipment and documentation in top shape, and help turn engineering designs into working, repeatable processes. This role is a great fit for someone who's meticulous with their hands, comfortable switching between different tools and processes, and just as comfortable writing a clear work instruction as they are running a piece of equipment.

What You'll Do

• Run a wide variety of fabrication and joining processes, including spot welding, vacuum furnace brazing, wire bonding for electronics packaging, electroplating, laser cutting, and similar processes
• Perform electrical and mechanical assembly, including electronics soldering
• Inspect parts and perform quality control checks to verify components and assemblies meet spec
• Log QC results and process data accurately and consistently
•  Work with engineering to design and build custom jigs, fixtures, tools, and test stands
•   Maintain, calibrate, and troubleshoot lab and shop equipment to keep it running reliably
• Write and maintain clear work instructions and Standard Operating Procedures (SOPs) for processes you run
• Flag process anomalies or deviations, and help investigate and resolve them
• Support engineers in setting up and executing experiments and test builds
• Continuously look for ways to improve existing processes, fixtures, and documentation

What We're Looking For

• Strong fine motor skills and hand-eye coordination — precision work is core to this role
• Hands-on experience with electrical/mechanical assembly and electronics solderin
• Experience with one or more joining/fabrication processes such as spot welding, brazing, wire bonding, electroplating, or laser cutting (we'll train on the rest)
• Comfortable working with and maintaining shop/lab equipment
• Solid written communication skills — able to write clear, precise work instructions and SOPs
• Reasonably computer savvy; comfortable logging data and working in tools like Google Docs/Sheets
• ​​​​​​​A detail-oriented, quality-first mindset

Nice to Have

•  Machine shop experience, including manual mill and lathe
• Basic CAD skills
•  Experience with 3D printing for prototyping fixtures/tools
• Background in a lab, R&D, or production environment involving process development and characterization

Location

On-site, full-time, in Somerville, MA.
