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, and with an office in Houston, TX, 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

• Lead mechanical and electro-mechanical design of Eden’s next-generation downhole 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.
• Manage a small, multidisciplinary team of mechanical engineers and technicians; set priorities, review designs, and mentor junior staff.
• 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.
• Apply Lean / Six Sigma methodologies to improve design, assembly, and test efficiency.
• Drive prototype builds from concept through lab validation and field deployment; lead design reviews, documentation, and milestone tracking.
• Support field mobilizations-configure, commission, and troubleshoot mechanical systems during test campaigns (travel ~10-20%).

About You

• Master’s or PhD (or equivalent experience) in Mechanical, Electro-Mechanical, or Materials Engineering.
• 7+ years of industry experience designing and validating mechanical or structural systems within the energy, utilities, or industrial-equipment sectors
• Proven leadership and managerial experience, including team supervision, cross-functional coordination, and project ownership.
• Strong proficiency with SolidWorks, ANSYS, or COMSOL Multiphysics for structural, thermal, and coupled electro‑mechanical simulations.
• Expertise in pressure‑vessel design, HPHT materials, sealing systems, and fatigue‑life assessment.
• Familiarity with electrical integration -designing mechanical components that interface with electrical enclosures, sensors, and cabling systems.
• Track record applying Lean / Six Sigma or similar continuous‑improvement frameworks.
• 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.

Preferred but Not Required

• Experience within the oil & gas or geothermal industries, particularly in downhole tool design or field hardware development.
• 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.

• 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
