Lead Geothermal Exploration Geologist (Hybrid/Remote)

Houston, TX

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 Lead Geothermal Exploration Geologist will lead geothermal exploration, geological evaluation, and subsurface characterization activities across selected lease areas and geothermal development opportunities, with a focus on identifying and advancing resources suitable for Enhanced Geothermal Systems (EGS) development. This role is responsible for translating regional geothermal concepts, lease-position data, and subsurface evidence into actionable exploration, acquisition, and resource development programs that support long‑term project execution and portfolio growth.

This role serves as a technical lead for geothermal exploration efforts, integrating geologic, geophysical, thermal, structural, geomechanical, well, and drilling datasets to develop conceptual three‑dimensional geothermal resource models. This individual will guide prospect ranking, exploration strategy, drilling recommendations, wellsite geology, and resource assessment in close collaboration with a team that includes reservoir engineering, geophysics, drilling, completions, land, permitting, and development.

Additional responsibilities include maintaining a positive corporate culture, promoting a safe and creative work environment, identifying and supporting opportunities for external collaborations, and other activities designed to improve Quaise.

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

Geothermal Exploration Strategy for EGS Applications

• Lead geothermal exploration strategy across selected lease areas, and portfolio growth opportunities supporting Enhanced Geothermal Systems (EGS) development.
• Develop geothermal play concepts and prospect‑ranking frameworks integrating resource potential, thermal regime, permeability, structural setting, stress state, infrastructure, permitting, and development risk.
• Identify and evaluate geothermal growth opportunities through lease‑area screening, prospect generation, land acquisition support, and technical diligence activities.
• Design and execute stage‑gated geothermal exploration programs, including desktop studies, geologic mapping, geophysical acquisition, geochemical sampling, temperature‑gradient assessment, exploration drilling, and appraisal planning.
• Develop exploration scopes, schedules, budgets, data‑acquisition plans, and decision criteria for advancing, pausing, or exiting exploration programs.

Lease‑Area Exploration Campaign Design

• Lead technical evaluation of geothermal leases from initial screening through drilling readiness.
• Define lease‑specific exploration objectives, technical risks, subsurface uncertainties, resource potential, and success criteria for EGS development.
• Design integrated exploration campaigns that may include geologic mapping, structural analysis, geophysical surveys, geochemical sampling, temperature‑gradient drilling, slim‑hole programs, exploration wells, and appraisal wells.
• Incorporate risk assessment, uncertainty analysis, contingency planning, and stage‑gate decision logic into exploration program design.
• Coordinate exploration campaign execution with drilling, completions, reservoir engineering, land, permitting, environmental, development, and HSE teams.

Drilling, Wellsite Geology, and EGS Development Support

• Lead geological support activities for geothermal exploration, appraisal, and drilling operations.
• Oversee wellsite…
