We’re seeking an inventive and versatile Development Test Engineer to design and operate testing for our next-generation geothermal power plants. You’ll own test campaigns from concept through execution, ensuring that prototypes and systems are validated for performance, safety, and reliability. This role bridges design, build, and commissioning—providing data and feedback that drive product improvements and production readiness. You’ll work closely with supply chain, manufacturing, thermodynamics, turbomachinery, and systems engineers, often serving as a central point of contact. Candidates must be comfortable in both lab and field environments, including international travel for commissioning support.
