BESS Electrical Engineer

Responsibilities

• Lead day‑to‑day technical oversight of utility‑scale LFP BESS assets, including performance monitoring, troubleshooting, and optimization of plant operation.

• Own the detailed understanding of LFP cell, rack, and container behavior, including degradation mechanisms, operating limits, and optimal charging/discharging strategies.

• Configure, review, and tune site control parameters (plant controller, PCS, BMS interfaces) to ensure safe operation, grid compliance, and adherence to performance guarantees.

• Experience with commissioning, performance testing, or root‑cause analysis of BESS or inverter‑based resources.

• Familiarity with ERCOT interconnection and market rules relevant to battery storage (e.g. telemetry, performance testing).

• Experience with high‑voltage substations, protection schemes, and grid‑code compliance for inverter‑based resources.

• Support ERCOT market integration of BESS assets, including understanding of applicable protocols, participation models, and operational constraints.

• Translate contractual requirements (EPC, OEM, interconnection, offtake, performance guarantees, warranties) into clear technical work structures, procedures, and acceptance/validation tests.

• Develop and maintain operating procedures, MOPs/EOPs, and runbooks for both normal and abnormal operating conditions, aligned with contractual and regulatory requirements.

• Analyze site data (SCADA, historian, event logs) to identify performance gaps, root‑cause recurring issues, and recommend corrective actions for LFP batteries and control systems.

• Collaborate with EPCs, OEMs, control vendors, and SCADA providers to implement control logic changes, firmware upgrades, and performance improvements.

• Provide technical input into outage planning, maintenance strategies, and lifecycle planning for LFP BESS assets.

• Support internal and external stakeholders by preparing clear technical documentation, reports, and presentations on system performance and compliance.

• Education & Experience Required

• Bachelor's degree in Electrical Engineering, Power Systems, Controls, or related engineering field (Master’s preferred).

• Minimum 4+ years of direct experience with LFP‑based battery energy storage systems at utility or large C&I scale.

• Demonstrated experience working with BESS assets in ERCOT (planning, interconnection, operations, or market participation).

• Strong understanding of LFP battery operations, including SoC/SoH management, thermal management, protection, and safety concepts.

• Hands‑on experience with site control systems (plant controller, PCS controls, BMS, SCADA), including reviewing setpoints, control modes, and coordination between devices.

• Ability to interpret and operationalize contractual documents (EPC contracts, OEM warranties, performance guarantees, availability and RTE requirements) into practical workflows and KPIs.

• Proficiency with data analysis tools (e.g., Excel, Python, or similar) for analyzing operational and performance data.

• Strong communication skills and ability to work cross‑functionally with operations, commercial, legal, and external partners.

• Personal Attributes

• Structured, detail‑oriented, and comfortable translating high‑level requirements into actionable work plans.

• Proactive problem solver who can work independently in a fast‑moving environment.

• Strong ownership mindset for asset performance, safety, and compliance.
