About the role
In a global landscape driven by innovation in energy use and storage, Tritium leads in the design, manufacture, and distribution of fast charging infrastructure for electric vehicles. Building on past successes, the company is now hiring a Power Electronics Engineer to report directly to the Head of Sustaining Engineering as part of the Sustaining Engineering team in Murarrie, Brisbane.
You will play a key role in the design, development, and optimization of high-voltage, high-power inverters and converters, ensuring reliable, efficient, and scalable solutions for EV charging systems. This position will focus on power circuit design, component selection, system simulation, and testing, while also supporting manufacturing, compliance, and field performance.
As a Design Responsible Engineer (DRE), you will own assigned power electronic systems and components, ensuring all solutions align with Design for Manufacturing (DFM), Design for Assembly (DFA), and Design for Serviceability (DFS) principles. You will collaborate with suppliers, manufacturing, quality, supply chain, validation, and certification teams to optimize system performance and reliability.
To Be Successful in This Role:
You will need a strong foundation in power electronics engineering, with proven experience in high-power electronics design, including inverter and converter topologies, IGBTs, MOSFETs, power drive circuits, and magnetics. Proficiency in DFM/DFA/DFS principles, power electronics simulation tools, and structured problemsolving methodologies is essential. Experience in fast-paced, innovative environments, along with the ability to balance competing priorities, will set you apart.
Problem Solving & Solution Implementation
• Investigate and resolve assigned power-related production and field non-conformances (NCR).
• Solve complex power electronics problems using Failure Mode and Effects Analysis (FMEA), 8D root cause analysis (RCA), and circuit simulations.
• Lead continuous improvement initiatives using Lean and Six Sigma methodologies to optimize power conversion efficiency and thermal management.
Design & Development
• Design and develop advanced high-voltage, high-power electronic systems, including inverters, converters, and power control circuits (3kW – 500kW).
• Implement, integrate, test, and debug complex power electronics components and systems.
• Select and specify power semiconductors, magnetic devices, capacitors, and power drive circuits for optimal performance and reliability.
• Utilize simulation tools such as MATLAB/Simulink, LTSpice, Simplorer, and Maxwell for power/frequency/integrity/thermal assessments.
• Design for EMC compliance, ensuring designs meet regulatory standards and certification requirements.
• Prototype and test high-power systems, performing real-time validation and field trials.Documentation & Compliance:
• Gather and document product design requirements to ensure solutions meet customer and compliance standards.
• Implement product changes and new feature requests using the Engineering Change Management (ECM) system.
• Maintain awareness of UL, CSA, IEC, CE standards and assist with compliance lab testing and certification activities.
Cross-Functional Collaboration:
• Work with Senior Engineers to improve power conversion efficiency and high-power circuit reliability.
• Collaborate with Software and Firmware Engineers to ensure smooth power system control integration.
• Collaborate with cross-functional teams to resolve electronic issues in high-powered equipment through the practice of failure modes and effects analysis (FMEA).
• Support Operations by releasing solutions through Change Management Control processes.
• Actively participate in meetings, providing technical guidance and documenting key decisions.
