Job description

GA Drilling is developing next-generation drilling technologies to unlock geothermal energy at depths and in conditions that conventional drilling cannot reach economically. Our mission is to make geothermal a scalable, baseload source of clean power by enabling reliable, efficient drilling in hard, hot rock. With engineering teams in the USA, Brazil, the UK, and across Europe, we are progressing rapidly toward commercial deployment of our technologies.

?

We are seeking a senior mechanical engineer with a practical bias to perform mechanical design for downhole drilling systems and associated equipment related to assembly, testing, and maintenance. The ideal candidate will be equally comfortable working with established processes and procedures, or with helping to develop and refine new ones.

?

?You will be based at our UK Gloucester Product Center.

?

The opportunity for you

?

You will be a core member of the operations team at our UK Product Centre, working closely with Engineering, Manufacturing, Supply Chain, and Quality & Compliance. Your work will ensure that drilling tools are produced, deployed, and maintained. You will have the opportunity to positively impact technology and processes as we move from prototype builds to commercial operations.

?

You will own:

?

1. Safety and Compliance

• Adhere to all health, safety, and environmental (HSE) regulations and quality procedures to ensure safe work practices.
• Promote and support a positive and proactive HSE culture.
• Maintain a safe, organized, and tidy work environment (5S, housekeeping, waste segregation).

?

2. Mechanical Design

• Perform mechanical design and analysis of mechanical components and systems for drilling technologies, and associated tooling and test equipment.
• Adhere to GA Drilling processes to ensure that equipment is safe, reliable, and efficient.
• Determine and perform calculations to support design and material selection (e.g., stress calculations).
• Use analytical skills to derive potential solutions to engineering problems and use engineering judgement to recommend suitable options.
• Generate high quality engineering documentation, including drawings, calculations, procedures, and reports.
• Lead and contribute to technical risk management.
• Plan equipment integration and commissioning.
• Lead and participate in design reviews.
• Create and own project requirements, budgeting, timelines, and specifications.
• Maintain equipment product files.
• Travel to field locations if required.

?

3. Assembly and Maintenance

• Create and refine equipment assembly, disassembly, maintenance, repair, and testing process and procedures.
• Assist on a hands‑on basis when appropriate, or when required.

?

4. Troubleshooting and Repair

• Lead or assist with diagnosing and repairing equipment failures.
• Lead or assist with failure reporting.
• Work with Engineering, Manufacturing and Quality & Compliance to elevate / solve technical or quality issues, and support investigations.
• Lead or assist with failure and cost of service delivery tracking

?

5. Collaboration

• Support other departments and functions e.g., manufacturing or supply chain to ensure seamless equipment deployment.
• Engage with external suppliers when required.

?
