Overview: The Manager, Reservoir Engineering Modeling leads Ormat&rsquo;s numerical modeling team and is accountable for the development, calibration, and application of reservoir models across the Company&rsquo;s operating fields, greenfield developments, and expansion projects. The team provides the long-term forecasts and reservoir strategies that underpin sustainable generation, development planning, drilling strategy, investment decisions, and portfolio growth forecasts.<br /> <br />The role is responsible for establishing Ormat&rsquo;s technical view of long-term reservoir performance, including generation potential, development capacity, make-up well requirements, and the uncertainty associated with these forecasts. The Manager ensures reservoir models are appropriately calibrated to available data, limitations and uncertainties are clearly communicated, and modeling results are translated into practical reservoir management and development strategies.<br /> <br />The Manager leads and develops a team of reservoir engineers and modelers and builds a center of excellence for geothermal reservoir modeling and forecasting. The role establishes technical standards, quality assurance, peer review, and consistent modeling practices across Ormat&rsquo;s portfolio while advancing the use of modern computational, data-science, and AI-enabled tools.<br /> <br />The position may also perform technical work directly, particularly on complex or strategically important assignments, while providing technical review, coaching, and guidance to the team. The Manager supports due diligence through critical review of third-party models and independent assessment of resource potential and represents Ormat with joint venture partners and other external stakeholders on reservoir modeling and long-term resource strategy.<br /> <br />
