About the role

Key responsibilities & impact
  • Lead performance analysis, monitoring, and operational reporting for standalone BESS and paired solar PV + BESS assets across a distributed generation portfolio.
  • Develop and monitor KPIs including Round-Trip Efficiency (RTE), State of Health (SOH), State of Charge (SOC), auxiliary power consumption, and system availability.
  • Develop degradation models and predictive analytics to forecast battery life, monitor SOH against capacity guarantees, and optimize charging and discharging cycles.
  • Extract, clean, and analyze large-scale SCADA, DAS, telemetry, and discrete-event datasets to identify underperforming assets, diagnose component failures, and recommend corrective actions.
  • Collaborate with Data Science teams to integrate BESS telemetry into enterprise platforms, optimize data warehousing, and automate internal and external reporting pipelines.
  • Evaluate the technical and operational impacts of standalone BESS and AC- and DC-coupled PV + BESS configurations.
  • Present technical and financial findings, recommend operational improvements and dispatch strategies, and communicate actionable insights to technical and non-technical stakeholders.

Requirements

What you’ll need
  • Bachelor's or Master's degree in Electrical Engineering, Computer Science, Data Science, Mathematics, Physics, or a related technical field.
  • 3–5 years of experience in performance engineering, battery modeling, energy storage analytics, or a closely related field.
  • Strong understanding of Battery Energy Storage Systems (BESS), battery architecture, degradation mechanisms, and performance modeling.
  • Experience with the operation, design, or analysis of AC and DC electric power systems.
  • Proficiency in Python, R, or SQL for data analysis, time-series manipulation, and modeling.
  • Hands-on experience with SCADA, DAS, telemetry, and operational datasets for power plant performance assessment.
