Analyze battery system performance, usable capacity, efficiency, availability, and compliance with contractual requirements.
Investigate abnormal performance trends, degradation indicators, and system limitations while driving corrective actions through resolution.
Independently diagnose complex issues involving BMS, PCS, EMS, SCADA, and monitoring platforms.
Analyze alarms, event logs, telemetry, and time-series data to identify root causes across hardware, software, controls, and configuration layers.
Develop electrical test plans, evaluate test results, and provide technical recommendations during root cause investigations.
Lead technical troubleshooting during Tier 1 outages, including diagnostic strategy, testing, system recovery, and validation.
Support battery capacity testing, performance testing, commissioning, integration testing, system tuning, and acceptance testing.
Serve as the primary technical escalation point for performance-related field issues.
Provide technical support to Field Service and Commissioning teams during critical troubleshooting and recovery activities.
Prepare technical reports, performance summaries, RCA documentation, and customer-facing technical findings.
Maintain detailed technical records to support continuous improvement initiatives.
Collaborate with Product Engineering, Software Engineering, and global engineering teams to improve system performance, firmware, software, and service processes.
Provide technical input for customer communications, technical risk assessments, and engineering decision-making.
