Planet A

GA Drilling is developing next generation drilling technologies to unlock geothermal energy anywhere on Earth. Our mission is to make geothermal a globally scalable, baseload source of clean power by enabling access to hard, hot rock at depths and temperatures that conventional drilling cannot reach economically.

Our work demands mastery across all facets of engineering—electronics, hydraulics, mechanics, systems, and control—and project management to create products that can survive and perform in harsh, high-temperature, high-load downhole conditions. Our technologies include smart downhole anchoring and drive systems that control the drilling process at the bit, plasma-based rock-destruction systems that fracture rock ahead of the drill bit, and innovative reeled drillstrings that redefine how hard-rock wells are constructed. These innovations—whether deployed individually or integrated into a groundbreaking autonomous reeled drilling system—enable hard-rock wells to be drilled further, faster, and safer than conventional technologies. With engineering teams in the USA, Brazil, the UK, and across Europe, and strong collaboration with leading operators, GA Drilling is progressing rapidly toward commercial deployment of these technologies.

We are seeking an engineer with 10+ years’ experience in electronics design, testing and manufacturing for downhole drilling systems, as well as prototyping operating and debugging the associated test equipment. The ideal candidate will be equally well versed in design, analysis, and test.

You will be based at our UK (Tewkesbury) office.

You will own

• Develop electronic hardware, analog and digital circuits, and embedded systems for downhole measurement and control applications.
• Creating system block diagrams, schematics, wiring harnesses and detailed electrical designs using engineering design software.
• Designing and implementing electrical stress tests (e.g., pressure, temperature, vibration) to ensure product reliability and durability.
• Conducting prototype board bring-up, functional testing, and performance analysis.
• Troubleshooting electronic faults at the component and system level using diagnostic tools such as oscilloscopes, multimeters, and spectrum analyzers.
• Providing technical support to field service technicians and on-site drilling crews to resolve operational problems.
• Look-ahead at validation requirements, and develop/execute test plans and test setups, utilizing both firmware and hardware debugging tools
• Support a positive and proactive HSE culture and ensure that all activities adhere to HSE Policy.
