Energy System Modeler

Energy System Modeler - Energy and Sustainable Busimess Program

This is a hybrid position which requires 8 days per month in the office. You will be based in our office in WRI Indonesia, Jakarta. Existing work authorization is required at the time of application submission as WRI is unable to sponsor any visa work sponsorship for this position.

Program Overview

WRI Indonesia’s Energy and Sustainable Business (ESB) Portfolio works to advance reliable, clean energy while reducing carbon emissions and supporting economic development. Recognizing the interconnected nature of economic, social, and environmental goals, the program collaborates across disciplines, including with WRI’s cities, climate, and ocean teams to integrate low-carbon technologies, quantitative models, and policy tools. These efforts align with national priorities such as accelerating Indonesia’s net-zero targets by 2050 for industry and 2060 for the broader economy.

To strengthen evidence-based energy planning, WRI Indonesia is expanding its analytical capability to better connect sectoral demand signals with clean energy supply opportunities. This includes developing integrated modelling frameworks that assess renewable energy availability, electricity system readiness, spatial demand distribution, and infrastructure requirements to inform strategic investment and policy decisions. This modelling work is expected to generate practical insights on where clean energy demand is emerging, how prepared the system is to meet that demand, and what infrastructure or policy interventions may be needed to accelerate reliable and low-carbon energy deployment.

Job Highlight

The Energy Modeler will serve as the primary technical role in developing, maintaining, and enhancing WRI Indonesia's energy system modelling platform, this include development of modelling methodologies, programming workflow, data processing and integration, scenario development, validation, and technical documentation to ensure the modelling platform remains transparent, reproducible, and scalable.

The Energy Modeler will work across Workflow 1 (Regional Decarbonization) and Workflow 2 (Industrial Decarbonization). Workflow 1 examines the implication of transport electrification on electricity demand, charging infrastructure requirements, and power system readiness, with the objective of enabling more coordinated planning between the transport and electricity sectors.

As the modeling platform continue to evolve, the role will also contribute to broader analytical work related to electricity systems, renewable energy deployment, industrial electrification, demand forecasting, infrastructure planning, and other clean energy supply initiatives. This work is organized around two broad focus areas, regional decarbonization and industrial decarbonization-related analytical work. In parallel, under Workflow 2 (industrial decarbonization), WRI Indonesia is developing a power demand mapping framework that spatially aggregates electricity demand across sectors and evaluates its implications for renewable energy deployment and transmission planning. Both initiatives require robust modelling capabilities to ensure the analytical framework remains technically sound, scalable, and adaptable as new data and stakeholder requirements emerge.

Reporting directly to Energy Research Analyst, this position will be based in Jakarta with office-flex working arrangement and will work closely with project leads and the research team within the Energy and Sustainable Business portfolio.
