Sr. Electronics Engineer

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.

Quaise is seeking a self‑driven, energetic, and experienced Electrical or Electronics Engineer to join our team in pursuing the world's most abundant source of clean energy by developing cutting‑edge high‑temperature electronics for downhole logging and measurement telemetry tools. The ideal candidate will have the ability to identify requirements from a simple set of end objectives, lead and participate in electrical design and integration efforts, and contribute to technology development for geothermal applications, which involves researching, designing downhole circuits, collaborating, learning, sourcing, integrating, implementing, performing design‑of‑experiments, analyzing results, and building on lessons learned.

(Reasonable accommodations may be made to enable individuals with disabilities to perform these essential functions.)
