An opportunity has arisen for a Senior Power Electronics System Engineer to lead the design, development, and integration of advanced electronic and high-voltage (HV) systems within a complex engineering environment.

This role is suited to a highly skilled engineer with a strong background in power electronics, embedded systems, and full lifecycle (V-cycle) development. The position involves ownership of system architecture, supplier engagement, validation strategies, and compliance with industry standards, particularly in safety-critical and high-performance applications.itectures, AUTOSAR platforms, and Hardware-in-the-Loop (HiL) testing for cutting-edge vehicle technologies.

• Lead system engineering activities for high-voltage (HV) subsystems, including power electronics modules such as DC-DC converters and HV distribution systems.
• Define, develop, and maintain high-level system architecture and technical requirements.
• Oversee full lifecycle development (V-cycle), from concept and design through to validation, production, and release.
• Support functional safety activities in line with ISO 26262, including DFMEA, DVP, design for manufacture (DFM), and root cause analysis (RCA).
• Collaborate with external suppliers and vendors to align on technical specifications, design reviews, and delivery milestones.
• Lead system integration activities, ensuring seamless interaction between hardware, embedded software, and vehicle/system-level requirements.
• Develop and implement end-of-line (EoL) test systems, including automated test solutions and custom hardware for validation and fault detection.
• Conduct environmental and reliability testing (e.g. temperature and humidity cycling) and ensure robustness of designs.
• Perform EMC/EMI testing and implement design improvements to meet regulatory compliance standards.
• Ensure compliance with manufacturing and assembly standards (e.g. IPC standards) across PCB design and integration.
• Support diagnostic and communication analysis using appropriate tools and scripting solutions.
• Contribute to configuration management, engineering change processes, and product release activities.
• Provide technical leadership, mentoring junior engineers and guiding multidisciplinary teams to deliver project objectives.

• Degree in Electronic Engineering, Electrical Engineering, or a related discipline.
• Extensive experience (typically 10+ years) in electronic system design and power electronics engineering.
• Strong understanding of high-voltage systems and safety-critical design environments.

• Expertise in analogue and digital electronic design.
• Strong knowledge of power electronics, including DC-DC converter design and HV systems integration.
• In-depth understanding of EMC/EMI compliance and associated testing standards.
• Experience with functional safety processes (ISO 26262) and supporting methodologies (DFMEA, DVP, RCA).
• Proficiency in embedded systems development and hardware/software integration.
• Experience with test system development, including automated validation frameworks.
• Strong understanding of PCB design, layout, and manufacturing standards (e.g. IPC-610, IPC-620).
• Ability to define and manage system-level requirements and architectures.
• Experience working with engineering tools such as:
• Altium Designer / OrCAD
• LabVIEW / TestStand
• CANalyzer (or similar diagnostic tools)
• SAP (or equivalent PLM/ERP systems)

• Experience with high-efficiency power conversion systems and advanced power electronics topologies.
• Knowledge of vehicle/system-level diagnostics and communication protocols.
• Experience with scripting or programming languages such as Python for automation and analysis.
• Familiarity with high-voltage safety procedures and authorised person responsibilities.
• Exposure to manufacturing test strategy development and production readiness activities.
• Experience working in highly regulated or safety-critical industries.

• Proven track record in delivering complex electronic and power electronics systems across industries such as automotive, aerospace, medical, or industrial sectors.
• Experience leading HV system development, including design, integration, and validation.
• Demonstrated ability to manage supplier relationships and technical interfaces.
• Experience developing automated test systems and custom validation hardware.
• Hands-on experience with environmental and reliability testing.
• Experience debugging and reviewing embedded software in conjunction with hardware systems.
• Experience working within structured engineering processes and gated project delivery frameworks.
• Prior experience leading or mentoring engineering teams.
