Wago Jobs in Texas (NOW HIRING)

Quaise Energy is unlocking Earth's deep heat to deliver clean, reliable, baseload energy at scale - almost anywhere in the world. As both a technology innovator and project developer, Quaise builds and operates solutions that harness superhot geothermal energy far below the surface, enabling power generation that can rival the output of today's most efficient fossil fuel and nuclear plants. Leveraging millimeter wave drilling, developed after more than a decade of research at MIT, Quaise's mission is to make superhot geothermal a backbone of the modern energy system, offering affordable, zero-carbon power and true energy independence for communities and nations everywhere. 

The Senior Controls Engineer will be responsible for control and instrumentation design, software development, solving electro-mechanical engineering challenges, and system integration for cutting-edge drilling technology. In this role you will work as an individual contributor on a team that is responsible for all work related to instrumentation, automation, and controls that will be used in the testing, development, and field deployment of a new direct energy drilling technology.

As a critical member of the team, you will be responsible for developing, building, and testing both software and hardware in a fast-paced environment to accelerate the technology's path to market. A primary focus of this role will be the development and maintenance of control software, ensuring seamless system integration and performance.
