Sr Software Engineer - Capacity Expansion

olicy constraints, and emissions targets into robust computational models.

• Support multi-region and inter-regional planning with long-term temporal and spatial resolution.

• Implement and improve large-scale optimization models, develop approaches for scenario analysis, sensitivity analysis, and long-horizon uncertainty.

• Build maintainable, well-tested, and well-documented code for production-grade planning tools.

• Design modular architectures that allow new technologies, policies, and constraints to be added over time.

• Improve runtime performance and memory efficiency for large datasets and long planning horizons.

• Integrate capacity expansion results with downstream models,

• Ensure data traceability and reproducibility of planning results.

• Collaborate with domain experts to validate model behavior and assumptions.

• Clearly communicate technical concepts and modeling results to both technical and non-technical stakeholders.Contribute to documentation and user-facing explanations of model logic and limitations.

Required Qualifications

• 5-8 years of experience with bachelor's or Master's degree in Computer Science, Engineering, Applied Mathematics, Operations Research, or a related field

• Strong programming skills in Python, Java, C# or similar. Familiarity with software engineering best practices (version control, testing, code reviews).

• Experience developing optimization-based models or large-scale analytical software.

• Ability to work with large datasets and complex model inputs.

Preferred Qualifications

• Experience with power system planning, energy markets, or grid modeling.

• Familiarity with capacity expansion models, resource adequacy, or long-term planning frameworks.

• Knowledge of renewable energy, storage, transmission planning, or decarbonization policy.
