• Lead prototype bring-up and debugging of power supply units in a high-voltage development lab environment
• Interface with internal engineering, programme management, and commercial teams to ensure design, schedule, cost, and quality objectives are met
• Summarise design results, document engineering decisions, and deliver technical proposals to senior management and customers

What We're Looking For

Essential:

• 8+ years of hands-on power electronics design experience, with a demonstrable focus on DC/DC converter and power supply development

• Proficiency with circuit simulation tools — SPICE-based simulators, PLECS, PSIM, or equivalent
• Excellent analytical and problem-solving skills; able to define the problem, collect and interpret data, and drive to a valid conclusion
• Strong communicator — equally capable of presenting technical detail to engineering peers and summarising results clearly for management

Desirable:

• Experience with Mathcad for analytical design documentation
• Familiarity with Cadence or Altium Designer for schematic capture and PCB layout
• Scripting or test automation experience for design validation and test generation workflows
• Background in high-voltage design up to 60 kV, including insulation coordination and HV safety practice
