Principal R&D Hardware Design Engineer (Power)

We are seeking a Principal R&D Hardware Design Engineer (Power) to join our hardware design organisation, working on advanced networking systems where power conversion, power distribution, power integrity, thermal constraints, and system-level trade-offs are business-critical.

As a Principal R&D Hardware Design Engineer (Power), you will act as a technical authority for power architecture, power circuit design, and board-level power distribution, influencing designs well beyond your immediate deliverables.

Responsibilities:

• Define and own power architecture and power distribution strategies for complex, high-performance networking platforms across multiple product generations.
• Design and optimise AC-DC and DC-DC power solutions, including voltage regulators, multiphase converters, hot-swap circuits, protection circuits, sequencing, monitoring, and control.
• Translate system requirements, load profiles, transient behaviour, thermal limits, reliability targets, and cost constraints into robust power designs with appropriate margin.
• Drive component selection and design trade-offs across efficiency, density, transient response, noise, thermal performance, reliability, availability, manufacturability, and cost.
• Partner with system architects, board designers, signal and power integrity engineers, mechanical and thermal teams, firmware, validation, manufacturing, suppliers, and program leadership across global sites.
• Lead power design reviews, simulation, schematic development, bring-up, characterisation, compliance testing, and complex root-cause investigations from concept through production.
• Establish power design standards, reference circuits, modelling practices, derating guidelines, and reusable solutions that improve quality and execution across programs.
• Mentor senior engineers, guide technical decision-making, and raise power design capability across the organisation.

Requirements:

• Bachelor’s or Master’s degree in Electronic Engineering, Electrical Engineering, or a closely related discipline.
• 10+ years of experience designing power circuits and power distribution systems for complex electronic products or hardware platforms.
• Demonstrated ability to define power architecture and make system-level trade-offs involving efficiency, density, transient response, thermal performance, reliability, and cost.
• Proven track record of solving ambiguous, high-impact power design, bring-up, validation, and field issues.
• Recognised technical leader who influences power design direction beyond a single team or project.
• Deep expertise in power conversion and distribution, including DC-DC converters, multiphase regulators, hot-swap and protection circuits, sequencing, telemetry, and board-level power delivery.
• Extensive hands-on experience with power simulation, measurement, validation, and characterisation, including efficiency, stability, ripple, noise, transient response, thermal performance, and fault behaviour.
• Advanced schematic and board-level design experience using Cadence OrCAD and Allegro, with strong understanding of PCB layout practices for high-current and noise-sensitive power circuits.

Benefits:

• Comprehensive suite of benefits supporting physical, financial, and emotional wellbeing.
• Investment in career development and growth.
• Unconditionally inclusive work environment celebrating individual uniqueness.
