This is an opportunity to be part of a world-class team at the nexus of two of the most exciting developments in energy today – big, real-time data and energy storage.

Stem creates innovative technology services that transform the way energy is distributed and consumed. Stem’s mission is to build and operate the largest digitally-connected energy storage network for our customers. Our world-class analytics will optimize the value of customer’s energy assets and facilitate their participation in energy markets, yielding economic and societal benefits while decarbonizing the grid. We create automated, price-responsive systems that enable C&I customers to predict and control electricity costs and capture savings in a rapidly-evolving utility landscape. The Stem system combines predictive analytics and advanced energy storage with a high-fidelity software user interface. By buffering spikes in energy usage, Stem also reduces the impact of the C&I customer on the utility grid and enables better grid citizenship. Through innovation in technology and financing, our goal is to optimize the relationships between energy providers and consumers.

Stem is looking for an effective System Optimization Engineer to work with other staff engineers and data scientists to analyze the operational characteristics of Stem’s Energy Storage Systems (ESS), and Energy Storage Devices (ESD), and leverages optimization software to collect, analyze and make data-informed recommendations on a comprehensive operational strategy that maximizes the overall battery capacity, lifetime and asset effectiveness. The candidate will also provide support for validating and reconciling cost & revenue streams. S/he will also initiate and lead energy analyses, making recommendations for next-generation ESS assets.

This person will work within Stem’s MRO (Maintenance & Repair Operations) team as key contributor of system optimization and performance management; working closely with the NOC (Network Operations Center), Field Services, Sustaining Engineering, Reliability Engineering, Customer Operations, Quality, Hardware & Software Development, and Data Science.
