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 creates geothermal boreholes anywhere in the world. Our initial focus is on residential and commercial heating/cooling. We’ve raised funding from top investors and are now looking to move from initial prototypes to a commercial drilling system.

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
