MECHANICAL TECHNICIAN

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 proactive mechanical technician to perform mechanical assembly, testing, and maintenance for downhole drilling systems. 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 Tewkesbury Product Center.

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.
