Job Description
As a Principal Systems Engineer, you will lead and drive system-level design, integration, and optimization for grid-scale Battery Energy Storage Systems (BESS). This senior role will focus on delivering innovative, safe, and cost-effective solutions while ensuring compliance with global standards and alignment with customer needs.
Key Responsibilities Include:
Develop and oversee system architecture for multi-MW BESS projects, integrating battery systems, power conversion systems (PCS), transformers, communication hardware, controls, and auxiliary power systems.
Review system requirements, ensuring compatibility and performance across all components. Drive the overall electrical system design and validation process.
Lead advanced load flow studies, short-circuit analysis, protection coordination, Harmonic , EMC and arc flash studies to ensure system reliability, safety, and grid compliance.
Develop and approve single-line diagrams (SLDs), power flow configurations, and control schematics for complex energy storage solutions.
Act as the technical authority for New Product Introduction (NPI), guiding design processes, lifecycle management, and risk assessments for the BESS system.
Collaborate with cross-functional teams (mechanical, thermal, software, testing) to ensure end-to-end system integration and alignment with customer and project goals.
Oversee system performance analysis, focusing on efficiency optimization, energy losses, and dynamic system modeling to validate performance under various operating conditions.
Provide leadership in selecting and validating key electrical components, including breakers, relays, fuses, inverters, transformers, batteries, and low-voltage switchgear.
Review and ensure product compliance with global and regional standards (UL 9540, NFPA 70, IEC, NEC, IEEE). Lead the certification processes and safety compliance audits.
Direct and mentor engineers in hardware testing strategies, FAT/SAT protocols, and prototype validation processes, ensuring systems meet stringent quality benchmarks.
Collaborate with vendors to evaluate, qualify, and optimize electrical subcomponents, fostering strategic partnerships.
Lead critical failure mode analyses (DFMEA) and root cause assessments (RCA) to ensure system reliability and continuous improvements.
Act as a technical advisor, providing expertise to project development, commissioning, and operations teams while incorporating feedback into system enhancements.
Deliver system-level documentation, including technical manuals, interface guides, and site design recommendations for internal teams and external stakeholders.
Drive innovation by identifying opportunities for scalability, cost reduction, and process improvements across the product lifecycle.
Mentor and develop engineering teams, fostering technical excellence, collaboration, and leadership within the organization.
Job Qualifications & Skills
Education: Bachelor s or Master s degree in Electrical Engineering (Full-Time) or equivalent.
