Senior Drilling 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.

The Senior Drilling Engineer will support the planning, design, engineering, and execution of complex geothermal well construction programs. This role translates subsurface, reservoir, completions, and development objectives into safe, practical, field-ready drilling plans, with responsibility for well design quality, operational readiness, risk mitigation, cost and schedule estimates, and continuous improvement across the drilling lifecycle.

This position works closely with exploration geology, reservoir engineering, completions, mechanical engineering, HSE, supply chain, permitting, and field operations teams to prepare drilling programs that can be executed safely and efficiently in the field. Success requires strong drilling engineering fundamentals, hands‑on operational judgment, disciplined technical assurance, and the ability to adapt conventional oil and gas drilling practices to high‑temperature geothermal applications and first‑of‑a‑kind well architectures.

This role is expected to provide engineering support before, during, and after field operations, including periodic travel to drilling sites and vendor or partner locations. Field support may include participation in pre-job planning, contractor readiness reviews, rig‑up or rig‑over activities, daily operations calls, technical troubleshooting, after‑action reviews, and end‑of‑well reporting.

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

• Prepare and deliver properly engineered and practical drilling and well construction programs, procedures, and cost estimates.
• Utilize continuous improvement practices in the well design process to reduce well cycle times & cost.
• Lead the technical planning process for assigned wells, including well design, casing and cementing programs, and risk assessment.
• Assist drill‑site supervisors in the preparation of “Plan Forward” drilling procedures and guidelines to be reviewed with drilling crew and service crews in each phase of the operation.
• Conduct offset data review of well histories and reconnaissance offset operations.
• Evaluate, select, and procure well construction services and materials including tubulars, wellheads, cement, bits, directional, and drilling contractors.
• Evaluate and select efficient, effective, and safe service contractors, and manage contractor performance.
• Maintain close communications with drill‑site supervisors and coordinate the preparation of quality daily drilling reports.
• Maintain close communications with technical service representatives including cement, mud, and rental equipment.
• Manage and maintain the Rim Base or Well View drilling database. Quality check field data input including casing tally, cement data, and wellbore schematics.
• Ensure EHS policies are adhered to across drilling operations.
• Ensure that drill‑site contractors are deploying safe work practices and that contractor safety programs are appropriate and in active practice.
• Embrace a multi‑disciplinary team approach to all aspects of the work.
