PCS_ Commissioning Engineer

The opportunity:

As a Commissioning Engineer for Battery Energy Storage Systems (BESS), your mission is to lead and execute comprehensive on-site commissioning, functional verification, and performance optimization of BESS control and automation systems globally. You will ensure the seamless integration and reliable operation of Battery Management Systems (BMS), Power Conversion Systems (PCS), Energy Management Systems (EMS), and associated control logic, delivering safe and high-performing BESS solutions to our customers worldwide.

How you'll make an impact:

• Lead the end-to-end functional testing and verification of BESS control logics, including BMS, PCS, and EMS.
• Verify the accurate configuration and operation of PLCs, RTUs, IEDs, and associated control logic for BESS applications.
• Perform comprehensive communication tests to ensure robust data exchange between all BESS components and the overarching control system using various industrial protocols.
• Conduct detailed troubleshooting of complex system interdependencies across hardware, software, and communication networks.
• Perform initial performance tuning and optimization of BESS control parameters to ensure optimal system response, stability, and efficiency.
• Coordinate extensively with project managers, site construction teams, client representatives, and subcontractors to ensure smooth commissioning progress.
• Lead by example, strictly adhering to all Hitachi Energy HSE Operating System, site-specific safety protocols, and Live Saving Rules during all on-site activities.
• Conduct proactive risk assessments (RAMS) and implement mitigation strategies for all commissioning tasks.
• Verify that BESS control and safety systems comply with relevant international and local standards (e.g., ISO/IEC, grid codes, electrical safety regulations).
• Prepare detailed commissioning reports, test protocols, as-built documentation, and punch lists for BESS control and automation systems.
• Provide comprehensive hands-on training and technical support to client operations and maintenance teams, ensuring their capability to operate and maintain the BESS.
• Contribute to the internal knowledge base by documenting common troubleshooting scenarios, developing best practices, and proposing improvements to commissioning procedures and tools based on field experience.
• Participate in cross-functional project meetings, providing crucial commissioning insights for planning and scheduling.
• Liaise effectively with remote engineering teams (electrical, software, protection) for technical support and complex issue resolution.
• Coordinate with vendors and suppliers of BESS components to resolve technical issues and ensure system compatibility during commissioning.
• Maintain clear and concise communication with clients regarding commissioning progress, challenges, and resolutions.
• Set up alarms, trends, and reports for performance monitoring and fault detection.
• Analyze system data to identify inefficiencies and recommend improvement
• Utilize Micro SCADA tools for system configuration, diagnostics, and performance tuning.
• Stay updated with the latest SCADA technologies and tools relevant to BESS.
• Prepare technical documentation including system architecture, configuration manuals, and user guides.
• Responsible to ensure compliance with applicable external and internal regulations, procedures, and guidelines.
• Living Hitachi Energy's core values of safety and integrity, which means taking responsibility for your own actions while caring for your colleagues and the business.

• Bachelor's degree in electrical engineering, Electronics Engineering, Control Systems Engineering, Automation Engineering.
• 5-10 years of progressive experience in engineering and on-site commissioning of industrial automation, control systems, and power electronics, with a strong focus on utility-scale Battery Energy Storage Systems (BESS) or large-scale renewable energy generation facilities. Experience with diverse battery chemistries (e.g., Li-ion, flow batteries) is a plus.
• Willingness and ability to travel extensively (up to 70-80%) globally to project sites for commissioning activities.
• Proficiency in both spoken & written English language is required.
