About GDC

Geothermal Development Company (GDC) is a wholly-owned state corporation in the Republic of Kenya. Established in 2008 following the unbundling of the energy sector, GDC operates within the generation sub-sector with the mandate to fast-track the development of geothermal resources in Kenya.

Position Overview

Grade: GDC 5

Reference Number: GDC/HRM/GRD/GRA/PGGPHY/01/2026

Job Purpose

The Principal Geophysicist will design, execute, and analyze geophysical exploration projects—utilizing advanced methods like MT, TEM, gravity, and micro-seismics—to map subsurface structures, reservoir boundaries, and guide the targeting of productive geothermal wells.

Key Responsibilities

• Plan, coordinate, and lead field geophysical surveys, including Magnetotellurics (MT), Transient Electromagnetics (TEM), gravity, and seismic surveys.
• Process and model 2D and 3D geophysical data to interpret subsurface heat sources, clay cap geometries, and structural conduits.
• Integrate geophysical interpretations with geological and geochemical data to build conceptual models of geothermal reservoirs.
• Provide scientific inputs and select target locations for exploration, production, and reinjection geothermal wells.
• Monitor and analyze micro-seismic activity in active geothermal fields.
• Compile comprehensive technical assessment reports and present scientific findings to technical review panels.

Requirements & Qualifications

• Bachelor’s degree in Geophysics, Applied Physics, or equivalent earth sciences.
• Registered or eligible for registration with a relevant professional geoscientific body (e.g., GSG).
• Minimum of 5–7 years of active experience conducting geothermal or mineral exploration geophysics.
• Advanced skills in using geophysical processing software (e.g., GMT, Winglink, Leapfrog Geo, Oasis montaj).
• Strong analytical, scientific writing, and field-work management skills.
