Thermofluids Modelling Engineer (Early Hire)

Intro Our Game Plan Are you hyped about solving humanity’s energy problems? Do you want to help unlock a limitless supply of clean energy? Does delivering one of the biggest engineering feats in history and drilling deeper than anyone ever before sound like fun? If so, we have an incredible opportunity for you. At Telura, we’re developing a new kind of drilling system which uses ultra-high-voltage electro-impulses to fracture hard rock and access geothermal energy, anywhere on Earth. The demand for clean energy is real, and recent advancements in research prove that the physics checks out — it’s a pure engineering challenge. We’ve completed key validation steps and are moving fast toward prototyping and proof-of-concept testing. We’ve spent the past months validating the opportunity and developing a playbook to build one of the world’s most ambitious geothermal companies. Now, we’re assembling a world-class team of curious, collaborative and ambitious builders - and we’re looking for a thermofluids modelling engineer to help design the systems that will keep our technology alive kilometres underground. Tasks What you’ll be working on Design and develop our mud delivery, extraction, and cooling systems — from first principles to field-ready Build CFD and thermal models of downhole conditions (fluid, rock, system interface) Simulate mud circulation, phase change, and heat exchange between the tool and environment Design and optimise cooling, flow, and thermal protection strategies Use experimental and field data to calibrate, validate and improve model fidelity Support integration of thermal systems into the overall drilling assembly Collaborate closely with mechanical and electrical teams on co-design and test Select and collaborate with external partners, suppliers and research labs Contribute to test planning and validation in high-stress, high-temp environments Work with the founders and product team on roadmap and technical decisions Requirements What you should bring Degree in Mechanical, Thermal, or Fluids Engineering — PhD ideal, but not required Deep expertise in CFD, heat transfer, and thermofluid dynamics Able to recommend and help establish appropriate modelling and simulation toolsets Ideally, experience with mud systems, geothermal, O&G, or deep mining Hands-on mentality: you enjoy building, testing, and tuning complex physical systems Structured and independent working style, with a willingness to take ownership Comfortable working in a hybrid setup (remote + on-site collaboration when needed), with potential to relocate to Munich in future Willingness to travel occasionally to partners, suppliers, and field sites Ideally, experience working in a start-up or dynamic development environment Benefits What we offer The opportunity to shape a company and the technology from the ground up - and get us moving along the road from lab to drilling the deepest holes on earth Significant responsibility and creative freedom from day one Direct collaboration with a founding team with nearly 30 years of experience in start-up, scale-up and bringing world-changing deep-tech to life A key position with strong growth potential as the company scales A dynamic, motivated team and an open, low-hierarchy culture Flexible working hours, modern tools, and a space to bring your ideas to life Equity options (e.g., ESOP / VSOP) available, and a company backed by a technical VC that believes in the technology and the vision Closing Ready to help unlock geothermal energy, everywhere? Tell us how you’d push the frontiers of deep geothermal drilling - and let’s drill deeper than anyone ever has.
