• Design and lead efforts on co-optimization across generation, transmission, distribution, and demand-side resources and fuels under uncertainty.

• Design and implement techno-economic frameworks to evaluate system reliability, flexibility, and cost-effectiveness.

• Conduct research in the area of electricity markets, power system reliability and optimization techniques and apply lessons learned to analytical approaches.

• Conduct research on electricity market design, policy implications, and emerging technologies.

• Propose and work on novel ideas and concepts for the next generation of power systems.

• Translate complex quantitative results into clear, actionable insights for technical and non-technical stakeholders including translating results of simulation cases and research into clear visual representations.

• Collaborate with cross-functional teams to deliver solutions for utilities, ISOs, and large energy consumers.

• Assist in proposal writing including strategizing on approaches to deliver innovative solutions to clients.

• Serve as a technical point of contact for clients, leading deepdive discussions, presenting analytical findings, and contributing to externally facing thought leadership, while supporting client satisfaction and retention in partnership with project and account leads.

Minimum Required Qualifications:

• Master's degree in operations research, Electrical Engineering, Applied Mathematics, Computer Science, Applied/Quantitative Economics or related field AND 3+ years of experience in an energy-related field.

Equivalent combination of education and directly relevant professional experience in lieu of an advanced degree, demonstrated by 6+ years of experience in an energyrelated field.

Energy-Related Experience Includes:

• Expertise in optimization theory, techno-economic analysis, and power system planning.

• Hands-on experience with capacity expansion and production cost tools (e.g., PLEXOS, IPM, Encompass, GenX, etc).

• Strong programming and modeling skills (Python, Julia, GAMS) and proficiency with commercial solvers (CPLEX, Gurobi, Xpress-MP).

• Ability to manage large datasets and perform stochastic or scenario-based analysis.

• Detailed-oriented approach to designing models and critically assessing results.

• Exceptional communication skills to present technical findings to diverse audiences.

Preferred Qualifications

• PhD in Operations Research, Electrical Engineering, Applied Mathematics, Computer Science, or related field.

• 8+ years of experience in an energy-related field.
