BESS Performance Engineer
We are:
Wizeline, a global AI-native technology solutions provider, develops cutting-edge, AI-powered digital products and platforms. We partner with clients to leverage data and AI, accelerating market entry and driving business transformation. As a global community of innovators, we foster a culture of growth, collaboration, and impact.
With the right people and the right ideas, there’s no limit to what we can achieve.
Are you a fit?
We are seeking a BESS Performance Engineer to join the Asset Management team, supporting a growing portfolio of distributed generation projects across the United States. Reporting to the VP of Engineering, this role will lead performance monitoring, analysis, and reporting for standalone Battery Energy Storage Systems (BESS) and solar-plus-storage assets, including AC- and DC-coupled configurations.
The ideal candidate combines expertise in battery performance modeling, renewable energy systems, and data analytics to optimize technical performance and commercial efficiency. Working closely with Data Science, Asset Management, Engineering, and Operations & Maintenance (O&M) teams, this individual will develop data-driven insights, automate reporting workflows, and identify opportunities to improve asset reliability, battery life, and energy market performance.
Key Responsibilities
•
BESS Performance Monitoring: Lead performance analysis, monitoring, and operational reporting for standalone BESS and paired solar PV + BESS assets across a distributed generation portfolio.
•
KPI Development & Tracking: Develop and monitor key performance indicators, including Round-Trip Efficiency (RTE), State of Health (SOH), State of Charge (SOC), auxiliary power consumption, and system availability.
•
Battery Degradation & Predictive Modeling: Develop degradation models and predictive analytics to forecast battery life, monitor SOH against capacity guarantees, and optimize charging and discharging cycles.
•
Data Analysis & Troubleshooting: Extract, clean, and analyze large-scale SCADA, DAS, telemetry, and discrete-event datasets to identify underperforming assets, diagnose component failures, and recommend corrective actions.
•
Data Integration & Automation: Collaborate with Data Science teams to integrate BESS telemetry into enterprise platforms, optimize data warehousing, and automate internal and external reporting pipelines.
•
Solar-Plus-Storage Performance: Evaluate the technical and operational impacts of transitioning from standalone BESS to AC- and DC-coupled PV + BESS configurations.
•
Performance Optimization & Reporting: Present technical and financial findings, recommend operational improvements and dispatch strategies, and communicate actionable insights to technical and non-technical stakeholders.
