Sr Software Engineer - Production Cost

Job Description Summary

Consulting Services is seeking a Software Engineer to advance our long-term power system planning software, with a focus on production cost modeling. In this role, you will contribute towards development of advanced capabilities inform multi-decade investment decisions for generation, transmission, storage under evolving reliability, economic, and decarbonization requirements. You will collaborate closely with our power system experts and software engineers to translate complex planning methodologies into scalable, reliable, and transparent software.

Job Description

Key Responsibilities

• Design, implement, and maintain software modules for production cost planning, including generation, storage, and transmission operating decisions.
  
  
• 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.
  
  

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