Job summary

Teragen Energy Corporation is seeking a Mechanical Engineer to act as a force multiplier across our technology organization. You will work across R&D, testing, stack engineering, manufacturing process development, and system integration, delivering fixtures, test stands, and tooling for high-temperature cell processing and stack assembly.

This is a 100% hands-on, cross-functional role reporting to the CTO. You will develop hardware for furnace fixtures, assembly tooling, and system concepts

Qualifications

• BS or MS in mechanical engineering or equivalent.
• Broad mechanical design fundamentals including fixturing, DFM, prototyping, and hands-on fabrication.
• Comfortable context-switching across multiple workstreams and priorities.
• Ability to make practical tradeoffs between speed, precision, cost, safety, and manufacturability.
• Interest in developing deep fluency in SOFC mechanics as we scale.

Responsibilities

• Design and build fixtures, test stands, processing hardware, and prototype tooling that support cell development, cell testing, and stack assembly. This is a 100% hands-on role.
• Partner with the Stack Engineering on component-level design of seals, manifolds, interconnects, and assembly.
• Support outsourced fabrication relationships when external fabrication is faster, safer, or more appropriate than in-house build.
• Work directly with Cell, Materials, Stack, and Test Engineering to translate constraints and data needs into working hardware.
• Maintain practical CAD, drawings, build notes, and design documentation so hardware decisions remain visible and reusable.

Job description

About Teragen Energy

Teragen Energy Corporation (“Teragen Energy”) is revolutionizing how AI data centers and broader industries get powered, by building the next generation solid oxide fuel cell platform. Rooted in the technology developed at Lawrence Berkeley National Laboratory and validated by ARPA-E, our mission is to deliver affordable, reliable, clean fuel cell power where it is needed the most to enable power security and flexibility for customers. Founded by technologists, scientists, and energy project developers, we are a fast-paced deep-tech company moving from lab-scale prototypes towards commercial module design - ideal stage for your work to directly shape how power is generated in 21st century, towards terawatt-hour scale.

This Role

As Teragen's first Mechanical Engineer, you will be the mechanical engineering force multiplier across our entire technology organization. Rather than owning a single subsystem, you'll partner with scientists and engineers working on R&D, testing, stack engineering, manufacturing process development, and system integration. This is truly a cross-functional role, not a traditional mechanical engineering role. You'll report directly to the CTO driving designs and building hardware that enables our Solid Oxide Fuel Cell technology to advance: high-temperature test stands, fixtures, processing equipment, manufacturing tooling, stack hardware, and prototype systems. One week you may be designing a furnace fixture for cell processing, the next developing assembly tooling for stack manufacturing or laying out new system concepts.

What You'll Do

• Design and build fixtures, test stands, processing hardware, and prototype tooling that support cell development, cell testing, and stack assembly. This is a 100% hands-on role.
• Partner with the Stack Engineering on component-level design of seals, manifolds, interconnects, and assembly.
• Support outsourced fabrication relationships when external fabrication is faster, safer, or more appropriate than in-house build.
• Work directly with Cell, Materials, Stack, and Test Engineering to translate constraints and data needs into working hardware.
• Maintain practical CAD, drawings, build notes, and design documentation so hardware decisions remain visible and reusable.

How We Work

Decisions here are driven by data, not seniority or consensus. We run minimal process and maximum communication. You will be trusted to work autonomously while keeping your work visible, documented, and impactful to the team.

What We're Looking For

• BS or MS in mechanical engineering with 0-6 years of experience; exceptional candidates at any level are encouraged to apply.
• Broad mechanical design fundamentals, including fixturing, DFM, prototyping, and hands-on fabrication or build experience.
• Comfortable context-switching across multiple workstreams and priorities in the same week.
• Ability to make practical tradeoffs between speed, precision, cost, safety, and manufacturability.
• Interest in developing deep fluency in SOFC mechanics as we scale.

Compensation Package

• Base Salary
• Competitive Employee Equity Grant
• 100% coverage for healthcare insurance for employees
• Unlimited time off program
• Eligibility for 401(k) plan

Teragen Core Values

• Openness and Boldness - Everyone on our team brings something special, including you. Communicate and collaborate openly, exchanging your best ideas with those around you.
• Be Innovative - Innovation is the execution of creativity. Pursue new ideas with rigor and speed.
• Plan, Execute, Deliver - Everything we do should have a purpose. Plan for the outcome we want, execute towards it relentlessly, and deliver what we said we would.
