## What You Will Do

The role involves dispatching Spearmint’s battery storage assets as a member of its Optimization team. The team member will execute energy and ancillary service offers in day-ahead and real-time markets, utilizing Spearmint’s internal software and associated forecasting tools.

This professional will report directly to the Head of Optimization and work closely with Spearmint’s Research team to utilize quantitative inputs from various sources.  They will retain authority to take discretionary actions when appropriate.  Understanding of short-term and long-term market risk, and experience in day-ahead and real-time markets is essential.  Familiarity with futures and other hedging markets is preferred.

The ideal candidate has experience analyzing and trading power, especially at the nodal level, and possesses a deep understanding of transmission topology, power generation dispatch and bidding, ISO LMP and ancillary service pricing, and power flow constraints.

Core Responsibilities:

- Participate actively in around-the-clock physical dispatch of battery storage resources.

- Monitor daily performance and risk metrics relevant to Spearmint’s operations; communicate performance transparently to relevant personnel internally and externally
- Understand when market conditions warrant interrupting automated market bidding, taking more discretionary action to optimize the asset’s optionality
- Execute trades manually when appropriate
- Contribute to Spearmint’s understanding of appropriate hedging activity to ensure adequate storage revenue over long term of offtake agreements
- Potentially execute in futures and options markets for energy price volatility as opportunities arise
- Develop bilateral relationships with counterparties and intermediaries representing companies whose exposures are complementary to Spearmint’s
- Structure transactions that enable Spearmint to manage exposures while maintaining optionality. Transact at attractive valuations
