Job description

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 controls engineer will be responsible for all programming related to our unique geothermal drill rig.This person will need an in‑depth working knowledge of controls theory, fault handling and HMI design.They will work closely with our CTO on overall software architecture and be responsible for all aspects of implementation.This role is highly hands‑on, and a successful applicant will be as comfortable coding behind a desk as they are in the field supporting the team while testing.

What You Will Do

• Design and develop controls for a custom drill platform
• Work with the hardware engineering team to test, trouble shoot and optimized control algorithms, fault handling, HMI screens and automation
• Created detailed specifications and documentation
• Support R&D efforts for novel drilling technologies

Who You Are

• 5+ years designing machine controls, automation or system software, ideally in the industrial equipment/construction/robotics industries
• Experience architecting robust, scalable software from the ground up, including establishing project structure, tooling, and development standards for a growing team, early‑stage startup experience a plus
• Experience coding HMIs of SCADA systems
• Comfortable coding in C++ and Python
• Proficiency working in embedded Linux environments, including CLI tooling, system, and networking
• Robust software engineering practices around source control (GitHub), testing, code review, and documentation
• External communications protocols experience such as WebSockets, REST, MQTT, or similar
• Proficient with designing and implementing unit testing
• Resourceful and highly collaborative team player who thinks creatively, has high attention to detail and quality, and who can work with a cross‑functional team that is trying to move as quickly as possible
• Comfortable interfacing with hardware teams and counseling technical documentation (e.g. APIs, datasheets, etc)
• Familiarity with hardware interfaces like SPI, I2C, UART, or CAN
• Experience with real‑time or timing‑sensitive software patterns in Linux environments
• UI framework experience for embedded or industrial systems (e.g. Qt/QML, NiceGUI, or similar)
• High attention to detail and excellent organizational and communication skills
• BS in Electrical, Software or Controls Engineering
