NextEra Energy Marketing is one of the nation’s leading electricity and natural gas marketers, and a key player in the energy markets in the United States and Canada. As a part of NextEra Energy Resources, we specialize in innovative energy strategies that maximize market value for our customers and stakeholders. Our team is skilled in market analysis, trading, risk management and delivering tailored customer solutions across North America. If you are a strategic thinker eager to make a significant impact in the fast-paced energy industry, join our team today.
Position Specific Description
The Senior Quant role is the senior-most individual contributor responsible for the mathematical and computational integrity of the trade floor’s grid and congestion models. The Senior Quant owns the most complex modeling problems linking physical grid behavior, ISO dispatch logic, congestion-driven price formation, and FTR/ARR auction modeling mechanisms, ensuring these models are quantified, scalable, and applicable for decision support.
Key Responsibilities
Advanced Power Systems & Market Modeling
Design, implement, and validate
DC/AC power flow and contingency models
that reflect real ISO dispatch, contingency logic, and constraint management practices; real-world experience in PJM or ERCOT is a plus.
Build and maintain high-fidelity representations of
flowgates, interface constraints, thermal and voltage limits
impacting DA/RT markets and FTR/CRR/ARR outcomes.
Develop
analytical frameworks
that connect: (1) grid topology and outages; (2) security-constraint economic dispatch/unit commitment; (3) binding constraints and shadow prices; (4) DA/RT price separation and FTR/CRR/ARR outcomes.
Serve as
technical authority on ARR/FTR/CRR auction modeling
assumptions, sensitivities, and failure modes.
Architect and maintain
market simulation engines
that replicate ISO clearing logic under numerous of topology, load, generation, and outage scenarios.
Perform rigorous
back-testing against historical DA/RT outcomes , identifying where models break, why, and how to correct the model or bias decisions.
Quantify
model risk and uncertainty : sensitivity to topology errors or forced outages, limiting assumptions, forecast noise, and rule interpretations.
Data, Algorithms & Implementation
Own the transformation of ISO and other internal data feeds into
model-ready representations .
Write
production-quality analytical code
that scales across years of historical data, supports scenario analysis, and integrates cleanly into current trading systems.
Define
modeling standards, numerical methods, and validation tests with documentation
so that results are explainable and defensible.
Required Qualifications
Bachelor’s degree (Master’s or PhD preferred) in Electrical Engineering, Power Systems, Applied Math, Physics, Computer Science, or related field.
5+ years
of progressive experience in ISO/RTO market modeling, congestion analytics, or power systems analysis.
Deep, practical understanding of
DC/AC power flow and contingency analysis,
ISO/RTO market mechanics, nodal pricing, congestion, and FTR/CRR/ARR mechanics.
Proficiency with industry tools (e.g., PSS/E, PowerWorld, Dayzer, Enelytix/TARA, Enverus Mosaic/Panorama, YES Energy or similar) and strong programming skills (Python, SQL, etc.).
Exceptional programming and numerical modeling skills; strong ownership mindset and ability to work independently.
Preferred Qualifications
Operational experience in ERCOT and/or PJM markets.
Experience collaborating with congestion trade desks.
