Junior/Senior Mechanical Engineer

Eden GeoPower Inc • Somerville, MA

14h • Onsite

About The Position

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.

Requirements

• 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 Haves

• 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.

Responsibilities

• Contribute to the design and build of Eden’s next-generation stimulation and energy-delivery systems operating at high temperature (>300 °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%).
