Mechanical Engineer III

About Us

Eden is pioneering sustainable natural resource recovery by using electricity to enhance subsurface permeability. Our Electrical Reservoir Stimulation technology offers a precise water-efficient alternative to traditional hydraulic fracturing reducing environmental risks while maximizing resource extraction.

Backed by leading public and private institutions we have raised $24M including $14M in dilutive capital from industry leaders such as Anglo American and Helmerich & Payne along with climate-focused investors like the Grantham Foundation. Additionally we have secured $10M in non-dilutive funding primarily through four DOE ARPA-E grants that support our R&D in frontier industries.

Headquartered in Somerville MA Edens team of 16 experts specializes in geophysics geochemistry high-voltage engineering and subsurface tool design. We are actively demonstrating our next-generation permeability enhancement technology across diverse geologies worldwide collaborating with industry leaders in geothermal energy geologic hydrogen carbon storage and mining to redefine resource recovery for a carbon-neutral future.

Looking ahead we are preparing for field tests in cooperation with our supportive technical partners.

Your Impact

• Fabricate assemble and test mechanical and structural hardware that houses and protects Edens electrical and power systems.
• Support senior engineers in the design of pressure housings enclosures and structural components then build and bench-test them.
• Run hands-on test setups: instrument hardware take measurements and help troubleshoot mechanical and electro-mechanical systems.
• Work directly with electrical and power-electronics teammates to integrate mechanical parts with enclosures sensors and cabling.
• Coordinate with machine shops fabrication partners and vendors to get parts made checked and delivered.
• Apply engineering fundamentals (textbooks hand calcs basic FEA) to size parts and check your work as needed.
• Learn on the job: take direction and feedback from senior engineers and grow your skills across design fabrication and test.
• Occasionally support field test campaigns (travel roughly 10%) helping configure and commission mechanical systems.

About You

• Bachelors (or equivalent hands-on experience) in Mechanical Electro-Mechanical or Materials Engineering.
• Roughly 0 to 4 years of experience with real time spent building things not only designing them on a screen.
• Genuinely hands-on: comfortable with a pipe wrench a multimeter and a machine shop plus general fabrication assembly and test setup.
• Working proficiency with SolidWorks for CAD. Able to reason through problems with fundamentals when needed.
• Some familiarity with electrical integration: building mechanical parts that interface with enclosures sensors and cabling.
• Eager to be coached: you take feedback well ask questions and want to grow under senior engineers rather than already having all the answers.
• Clear communicator who can work across electrical mechanical and geoscience teammates in a fast-moving R&D startup.

Nice to Have

• Experience with pressure systems high-temperature hardware or other demanding physical environments.
• Familiarity with dielectric materials electrode housings or sensor and data-acquisition integration.
• Machine shop certifications or hands-on manufacturing training.

• Medical dental vision 401k
• Vacation Federal holidays off Thanksgiving holidays Christmas and New Year 15 additional workdays per year (3 weeks) vacation time
• Sick days bereavement time
• Stock Options
