Lead Power Electronics Engineer — DC/DC Converters | High Voltage up to 60 kV

About This Opportunity

Ampere Recruitment is engaged exclusively on this search on behalf of a well-established power electronics engineering organisation operating across semiconductor, industrial, and medical markets. We are seeking a Lead Power Electronics Engineer to take ownership of the design and development of advanced high-voltage DC/DC power conversion solutions up to 60 kV at the heart of a technically ambitious product development programme.

This is a role for an engineer who is as comfortable at a lab bench validating a prototype as they are presenting a design proposal to senior stakeholders. If you have deep power electronics design experience and want to lead technically rather than manage administratively, this is worth a conversation.

The Role

As Lead Power Electronics Engineer, you will drive the full design lifecycle of high-voltage power supplies and DC/DC converters — from initial concept through to validated production release. You will work as a key technical contributor within a focused engineering team, bringing together circuit design, magnetics, simulation, and hands-on prototype validation under one remit.

Specifically, you will:

• Lead the design and development of efficient, cost-effective power conversion circuits and power supplies to customer and regulatory specifications — spanning analog and digital circuits, embedded control logic, magnetics, EMI filters, and HV power stages
• Own the full hardware development process: schematic capture, PCB layout direction, prototype build, bench testing, and firmware/code development for embedded control
• Develop analytical models, simulation tools, and predictive design methods that reduce iteration cycles and improve first-pass design success
• Analyse test data against functional and performance specifications, identifying root cause and driving design resolution where required
• 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
• Strong working knowledge across the full power electronics design toolkit: analog and digital circuit design, magnetics design, EMI/EMC, thermal management, and embedded control
• Experience designing to customer and regulatory specifications across one or more of: semiconductor capital equipment, industrial, or medical applications
• Proven ability to take a design from concept to validated hardware independently, including schematic capture, layout, and lab bring-up
• 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

Education

• BEng / BSEE or equivalent in Electrical Engineering, Power Electronics, or a related discipline. Equivalent experience considered.

Magnetics Design

• Direct experience designing and specifying magnetic components — transformers, inductors, common-mode chokes, and planar magnetics — for power supply applications.
• Solid understanding of core loss modelling (Steinmetz, iGSE), winding loss analysis, leakage and magnetising inductance, and skin/proximity effects.
• Familiarity with core materials (ferrites, nanocrystalline, amorphous), core geometries (EE, ER, planar, toroidal), and winding techniques (Litz wire, PCB windings).
• Experience with magnetics simulation tools (e.g. ANSYS Maxwell / PExprt or similar) is advantageous.

Technical & Professional

• Degree in Electrical Engineering, Power Electronics, or a closely related discipline.
• Excellent communication skills — comfortable presenting complex technical concepts to both engineering and commercial audiences.
