Power Electronics Engineer

About the role

We are seeking a hands-on, mid-level Power Electronics Engineer to join our R&D team. The role focuses on circuit design, schematic capture, PCB layout, prototyping, testing and troubleshooting of power-conversion products. The successful candidate will have practical experience designing reliable PCBs for high-voltage, high-current and high-frequency applications. Mechanical design experience would be an advantage.

Key responsibilities

• Design AC/DC, DC/DC and PFC power-conversion circuits.
• Develop schematics and multilayer PCB layouts using Altium Designer.
• Optimise PCB designs for high voltage, high current, thermal performance and EMC.
• Apply appropriate creepage, clearance, grounding and isolation requirements.
• Select components and perform circuit calculations, simulation and design verification.
• Support the design of power stages, gate drives, sensing, control and protection circuits.
• Coordinate PCB fabrication, prototype assembly and component sourcing.
• Conduct prototype power-up, testing, debugging and root-cause analysis.
• Prepare design documentation, bills of materials and manufacturing files.
• Support EMC, electrical-safety, certification and production-release activities.

Desirable Experience

• Medium- or high-power systems above 10 kW.
• Three-phase power systems and resonant converters.
• EV chargers, battery energy storage or data centre power systems.
• High-voltage DC or 800 V architectures.
• Silicon Carbide power devices.
• PSIM, LTspice or similar simulation tools.
• Embedded C, DSP or microcontroller-based digital control.
• CAN, Modbus or Ethernet communications.
• EMC and electrical-safety certification.

About you

• Approximately 3–7 years' experience in power-electronics or electronic-product design.

• Experience developing AC/DC, DC/DC, PFC or switched-mode power supplies.

• Strong hands-on experience with Altium Designer.

• Proven experience taking PCB designs from schematic capture to production-ready files.

• Experience designing multilayer PCBs with power, analogue, digital and communication circuits.

• Good understanding of high-current layout, switching loops, grounding, isolation, thermal management and EMC.

• Knowledge of creepage, clearance and electrical-safety requirements.

• Experience with power semiconductors, gate drives, magnetics, sensing and protection circuits.

• Practical laboratory experience with oscilloscopes, current probes, power analysers and electronic loads.

• Must have a Bachelor's degree in Electrical Engineering, Electronic Engineering, Power Electronics or an equivalent discipline.

• Understanding of Design for Manufacturing and Design for Test principles.
