Senior Mechanical Engineer (Advanced Drilling Systems)

Senior Mechanical Engineer – Advanced Drilling Systems Gloucester, UK · Permanent Design downhole tools for rock conventional drilling can't touch. Then build them, test them and watch them work. GA Drilling builds technology that drills hard, hot rock deeper and more cheaply than conventional methods. That's what will make ultra-deep geothermal energy possible anywhere. We're hiring a Senior Mechanical Engineer to design the downhole tools that get us there. If you've spent your career designing downhole tools and still want to be there when the prototype goes together, read on. WHAT YOU'LL DO * Design, analyse and test. Own the mechanical design of downhole drilling systems. * Take tools all the way. Lead from concept through prototype and qualification to market. * Build the test setup. Specify the tooling, fixtures and support equipment for build and test. * Document it properly. Produce clear drawings, calculations, test procedures and reports. * Make the call. Weigh up the options and recommend the right engineering answer. * Manage technical risk. Identify, assess and mitigate it across the product lifecycle. * Work across the business. Partner with manufacturing, procurement, QHSE and suppliers. WHAT YOU'VE ALREADY DONE * You have 20+ years designing, building, testing and repairing complex downhole tools with hydraulic, electronic and mechanical subsystems. (Downhole is preferred but not essential) * You've designed for high temperature, high pressure, vibration, shock and abrasive rock. * You know machine design deeply: mechanisms, hydraulics, actuators, structures, materials, fatigue. * You've been hands-on during build, assembly and test, not just at the CAD station. * Ideally, you've led or mentored engineers as a functional lead or recognised expert. * You work in Inventor, Autodesk Vault, ANSYS (FEA/CFD) and SAP. * You have a bachelor's degree in mechanical engineering; a master's is preferred. * You have the right to work in the UK without sponsorship. HOW YOU WORK You take high-level direction and deliver against the plan without needing to be managed. You give and take direct, technically grounded feedback, because that's how tools get more reliable. And you keep safety and quality at the centre of everything you build. WHAT YOU GET * Hard problems nobody has solved yet: making ultra-deep geothermal a commercial reality * Technology with the potential to change how the world gets its energy * An experienced, highly motivated team * Work with the world's leading drilling operators and service companies * A competitive benefits package JBRP1_UKTJ
