Tech Specialist - Aircraft Power Electronics
Eaton MSD Cheltenham is looking for a Tech Specialist - Aircraft Power Electronics. In this role you'll provide senior technical leadership for the architecture, design, verification, and certification support of safety-critical power electronics systems for high-voltage DC and AC aircraft power distribution and conversion.
Key applications include electrothermal ice protection power controllers (up to 160 kW), HVDC power distribution units, DC-AC motor drives, and power supplies in the 2 kW to 10 kW range.
Drive the adoption of advanced power electronics technologies, including wide-bandgap semiconductors (SiC, GaN), high-voltage isolation, digital control, and model-based design, ensuring robust, certifiable, and production-ready solutions.
Operate within safety-critical development frameworks aligned to ARP4754A, ARP4761, DO-178C, DO-254, and DO-160, up to DAL A where required.
What you’ll do:
- Define and solve complex, multi-disciplinary engineering problems, with focus on HVDC/AC conversion, protection, thermal design, EMC, insulation, reliability, and certification risk.
- Lead the power electronics technical strategy and technology roadmap in collaboration with the Technical Authority.
- Provide leadership, supervision, and coordination to engineering teams to deliver work on time, cost, and quality targets.
- Act as a senior technical authority and customer-facing escalation point for HV power systems, ensuring high-quality engineering delivery.
- Sponsor or lead strategically important programmes (e.g., intelligent PDUs, IPS controllers, motor drives, HV demonstrators).
- Maintain awareness of emerging technologies and translate developments (SiC/GaN devices, sensing, magnetics, thermal management, EMI) into product strategies.
- Define engineering standards, including design rules, derating, HV spacing, protection methods, and EMC practices.
- Lead trade studies across converter topologies, motor control, and protection strategies.
- Support bid activities, including technical input, estimation, and risk identification.
- Mentor engineers across technical, product, and lifecycle domains.
- Investigate equipment failures and recommend solutions.
- Prepare and review engineering estimates, identifying risks and dependencies.
- Produce reports and present technical findings to stakeholders.
- Maintain professional competency and support continuous development.
- Adhere to company values, policies, and procedures.
- Perform off-site duties as required and support broader business needs.
Reasons to use Rodeo
Start with a chat, not a search bar
Grad scheme, placement, apprenticeship? Not sure what you want yet — that's fine. Your agent talks it through with you and turns "I have no idea" into a shortlist.
It searches the market for you
Every day your agent scans the market matching roles against what actually matters to you, not just keywords on a CV.
Only hits
No noise. No "maybe this fits." Just roles with a clear explanation of why they're right — and where to focus when applying.
Qualifications:
- Degree (typically Master’s) in Electronics Engineering or equivalent experience, with significant relevant industry experience.
- Specialisation in power electronics, motor drives, high-voltage engineering, or aerospace electrical systems preferred.
- Chartered Engineer (or equivalent) desirable.
- Desirable: postgraduate study or training in power electronics, EMC, high-voltage safety, or safety-critical systems.
Skills:
- Advanced expertise in high-voltage power electronics design, including conversion, control, sensing, protection, and gate drive systems.
- Ability to define requirements and ensure full traceability from safety requirements to verification evidence (including DAL A).
- Strong experience in EMC design and compliance for high-speed switching systems (SiC/GaN), including emissions, susceptibility, filtering, shielding, and layout.
- Proficiency in simulation and analysis tools (e.g., SPICE, PLECS/PSIM, thermal/electromagnetic modelling, stability analysis, worst-case and reliability analysis).
- Experience with validation and test methods including switching loss, thermal characterisation, insulation testing, HIL, load testing, and qualification.
- Solid understanding of PCB design for high-voltage/high-current systems, including creepage/clearance, parasitics, and manufacturability.
- Component selection expertise across power semiconductors, magnetics, capacitors, sensors, and insulation systems.
- Experience with HV architectures including DC distribution (270–800 VDC), inverters, motor drives, SSPCs, and power supplies.
- Ability to lead technical reviews (PDR, CDR, TRR, qualification, production readiness).
- Manage and support suppliers for key components and subsystems.
- Collaborate effectively across software, mechanical, systems, manufacturing, and test disciplines.
- Contribute to architecture definition for key products (PDUs, converters, inverters, motor drives).
- Provide technical leadership and influence engineering direction within the organisation.
