Key Responsibilities

Electrical System Engineering

• Lead electrical design and integration efforts for utility-scale BESS applications.
• Develop system architecture, protection concepts, and interface requirements across AC and DC domains.
• Collaborate with mechanical, controls, firmware, and system engineering teams to ensure end-to-end design cohesion.
• Prepare and review key engineering deliverables including, Single Line Diagrams (SLD), Schematics and wiring diagrams, General Arrangement (GA) drawings, Cable schedules, cable harness layouts, and routing plans
• Ensure design packages meet quality, safety, and manufacturability requirements through all project phases.

Component Selection Sizing

• Perform technical sizing and selection of electrical components including, Switchgear, breakers, fuses, and disconnects, Busbars and distribution equipment, LV/HV AC components and DC subsystem components, Transformers, auxiliary loads, and power conditioning equipment.
• Review vendor specifications, conduct technical evaluations, and support procurement decisions.

Auxiliary Systems BoM Management

• Design auxiliary electrical systems including transformer selection, auxiliary distribution, and control/power wiring strategies.
• Prepare accurate Electrical Bills of Materials (BoM) and maintain documentation throughout design iterations.

System Studies Analysis

• Perform AC and DC arc-flash studies, short-circuit analysis, and system modelling using MATLAB and other analysis platforms.
• Support protection coordination, load flow studies, grounding system evaluation, and overall system safety assessments.

Standards Compliance

• Ensure all engineering activities adhere to applicable electrical standards and codes such as: NFPA, NEC, IEC, and UL
• Drive compliance, safety, and best practices throughout design and testing cycles.

Required Qualifications
