Senior Power Electronics Design Engineer
Location: Middlesex / Hybrid
Salary: Competitive excellent benefits

A fantastic opportunity has arisen for an experienced Power Electronics Design Engineer to join a leading engineering organisation operating at the forefront of the defence and aerospace sectors.

This is a key technical position, offering the chance to lead the design and development of advanced high- and low-voltage switch-mode power converters and associated control systems. You’ll be involved throughout the full product lifecycle — from initial concept through to production — developing robust, efficient, and reliable designs for high-performance applications operating in demanding environments.

• Lead the design and development of new power conversion systems and control circuitry.

• Define and optimise circuit topologies and architectures to meet challenging performance, size, and efficiency targets.

• Design analogue and digital control and monitoring circuits for complex power systems.

• Use modelling and simulation tools to analyse, validate, and optimise circuit performance.

• Collaborate with mechanical, production, and manufacturing teams to ensure designs are reliable, repeatable, and manufacturable.

• Support the New Product Introduction (NPI) process through design reviews, production readiness, and handover to manufacturing.

• Provide technical guidance, mentoring, and leadership to junior engineers.

• Perform root cause analysis and drive design and process improvements.

• Act as a technical authority for key product lines, supporting bids, proposals, and customer reviews.

• Deliver internal R&D projects on time, within budget, and to the required technical standard.
  
  

• Degree, MSc, or PhD in Electronics or a related discipline.

• Proven experience in the design and development of switch-mode power supplies (SMPS), including high-voltage and high-power systems.

• Strong understanding of analogue and digital control design principles.

• Skilled in circuit simulation, modelling, and analysis.

• Familiar with FMEA, DFMA, and design-for-manufacture principles.

• Experience leading design projects within a multidisciplinary engineering environment.
  
  

• Experience working within the defence, aerospace, or other high-reliability sectors.

• Familiarity with relevant military and aerospace design standards.

• Knowledge of high-voltage design and associated safety and compliance requirements.

• Understanding of configuration control and quality assurance processes.
  
  

• Technically strong with a methodical, detail-oriented approach.

• Excellent communication and cross-functional collaboration skills.

• Organised, proactive, and able to take ownership of complex design challenges.

• Committed to continuous improvement, innovation, and engineering excellence.
