Job description

About Dig Energy, Inc.

Dig Energy is an early stage startup enabling affordable geothermal energy for heating, cooling, and refrigeration. We have developed and are deploying a radically inexpensive drilling method that can economically scale geothermal boreholes anywhere. Our initial focus is on commercial heating/cooling. We’ve raised funding from top investors and are now looking to refine our drilling system as we move through our first large projects. Due to the hands‑on nature of our work, this is an on‑site role, and we’re looking for someone who can come into our office in Manchester, NH.

The Role

We are looking for multi-disciplinary and experienced engineers that can own and execute on core engineering challenges while building processes for quality and scale. The Mechanical Engineer will drive pieces of mechanical design, electro‑mechanical packaging, product development and manufacturing. This role will be heavily hands‑on engineering and execution focused.

What You Will Do

• Concept development, evaluation and down selection of mechanical systems

• Detailed design and validation of key components and sub‑modules

• Component and system level analysis

• Perform systems/material testing to help refine designs

• DFM work with the team to establish robust fabrication and assembly procedures

• Design system components, including detailed drawings for manufacturing using best practices and GD&T

• Product development for novel drilling and geothermal installation systems

• System level lab and field testing

Who You Are

• 5-15 years of hands‑on mechanical engineering experience

• Experience in a fast‑paced, execution‑oriented early stage startup

• Resourceful and highly collaborative team player who thinks creatively and who can work with a fast pace, cross‑functional team

• Thorough understanding and use of technical principles, theories, and concepts in mechanical and mechanical systems engineering

• High attention to detail and excellent organizational and communication skills

• Fluent using CAD systems such as SolidWorks

• Experience in engineering analysis such as FEA, CFD, FMEA or PFMEA is a plus

• Working knowledge of manufacturing techniques such as injection molding, sheet metal fabrication, welding, machining and 3D printing

• Familiarity with moving products from R&D through Design and into Manufacturing

• Comfortable creating engineering documentation including 2D part drawings, assemblies and schematics

• BS in Mechanical Engineering, mechatronics, or related field
