Location: Napier, New Zealand.

This role is contributing to the Critical Power product group in New Zealand.

You will be mainly accountable for:

Lead the hardware design and development of the Battery Energy Storage Systems (BESS) and Uninterruptable Power Supply (UPS).
Contribute to the analysis and validation of low and medium-voltage energy management systems, including system protection schemes, power quality optimisation, energy storage integration, and evaluation of magnetic components.
Perform electrical design activities including cable and harness dimensioning, selection, routing and layout, and definition and selection of protection devices, sensors and power supplies.
Conduct comprehensive functional, performance, and safety testing on BESS and UPS, ensuring compliance with industry standards (IEC/UL certifications).
Develop, improve, and maintain accurate technical documentation including test procedures and plans, commissioning guides, user manuals, product drawings, and interface specifications for battery systems.
Plan and execute system commissioning activities on customer sites, including pre-commissioning inspections, power-up sequences, functional verification, performance optimization, and troubleshooting across all product lines.
Troubleshoot and diagnose electrical faults, power quality issues, and system performance problems; develop improvement strategies and provide technical guidance to support customer applications.
Develop deep expertise in ABB's power conditioning portfolio (BESS and HiPerGuard) and stay current with emerging power and energy management technologies.

Qualifications for the role

Strong understanding of Battery Energy Storage Systems (BESS) and power converters >200kW.

Minimum 5 years of experience designing/maintaining power electronic systems within specialist teams; capable of leading engineering projects and guiding junior colleagues.

Solid understanding of three-phase systems and power electronics, including inverter and converter operating principles, practical application and integration into systems, and the ability to interpret product specifications and operate within defined performance and safety margins.
Knowledge of grid compliance requirements, including grid codes, power quality standards (harmonics, THD, power factor), fault ride-through, frequency and voltage regulation, and anti-islanding protection, with familiarity with relevant IEC and IEEE standards is desirable.
Foundational knowledge of electromagnetic compatibility (EMC) principles, including conducted and radiated emissions, immunity requirements, and common mitigation techniques such as filtering and shielding, with familiarity with relevant standards.
Foundational knowledge of thermodynamics, including heat management and airflow optimization within electrical cabinets to ensure reliable and safe equipment operation.

Proficiency with AutoCAD and circuit simulation tools (e.g., PSCAD, Matlab/Simulink) is a plus.
Understanding of control methods with ability to communicate effectively with control engineering teams to ensure seamless system integration.
Proven ability to apply innovative thinking and technical creativity across complex R&D assignments and challenging engineering problems.
Bachelor's degree in Electrical Engineering and/or Power Electronics Engineering; postgraduate qualifications are desirable.
Strong English communication skills with demonstrated ability to collaborate effectively across multiple functions, technical domains, and multi-site engineering teams.
