Junior/Senior Mechanical Engineer
Eden GeoPower Inc
Job Description
Job Description
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, Eden's 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
- Contribute to the design and build of Eden’s next-generation stimulation and energy-delivery systems operating at high temperature (>300 °ree;C) and high pressure (>10 000 psi).
- Architect structural and mechanical systems surrounding electrical assemblies, ensuring reliable integration and compliance with thermal and pressure constraints.
- Perform FEA / CFD modeling for stress, vibration, fatigue, and heat transfer in cyclic HPHT environments.
- Design and qualify pressure vessels, housings, and protective enclosures to relevant ASME and ISO standards.
- Collaborate with electrical and power-electronics teams to achieve seamless electro-mechanical performance and thermal management.
- Engage directly with vendors, fabrication partners, and suppliers to ensure manufacturability, quality, and cost-effectiveness.
- Support field mobilizations—configure, commission, and troubleshoot mechanical systems during test campaigns (travel ~10–20%).
Requirements
About You
- Bachelors (or equivalent experience) in Mechanical, Electro-Mechanical, or Materials Engineering .
- 3-10 years of industry experience designing and validating mechanical or structural systems
- Proficiency with SolidWorks, ANSYS, or COMSOL Multiphysics for structural, thermal, and coupled electro-mechanical simulations.
- Familiarity with electrical integration —designing mechanical components that interface with electrical enclosures, sensors, and cabling systems.
- Hands-on approach—comfortable with machining, fabrication, assembly, and test setup.
- Excellent communicator who can bridge disciplines between electrical, mechanical, and geoscience teams in a fast-moving R&D startup.
Nice to Have
- Familiarity with dielectric materials, electrode housings, or thermo-mechanical coupling .
- Background in geomechanics, rock-tool interaction modeling , or fracture-mechanics coupling.
- Experience integrating sensors, data acquisition , or diagnostic instrumentation in HPHT systems.
- Exposure to industrial-utility environments involving complex mechanical-electrical system interfaces.
Benefits
- 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
