Ampere Recruitment is partnering with a leading power semiconductor business to identify an exceptional Senior Power Applications Engineer. This is a high-impact, technically deep role sitting at the intersection of GaN/Si MOSFET device physics and real-world MHz switching converter design, a genuine opportunity to shape how next-generation power devices reach the market.
If you thrive in the lab, can translate device characteristics into compelling application insights, and relish working with both silicon teams and demanding end-customers, this role will feel purpose-built for you.
THE OPPORTUNITY
Working across cross-functional teams spanning device design, marketing, and field applications, you will own the complete applications lifecycle for high-frequency DC/DC converters from MOSFET parameter specification through prototype validation, competitive benchmarking, and customer engagement. You will be the technical authority bridging device capability and end-application performance, with your work directly influencing product roadmaps and go-to-market strategy.
KEY RESPONSIBILITIES
- Define and specify critical MOSFET parameters for MHz-range DC/DC converter topologies, working closely with device engineers to align datasheet targets with real application demands.
- Lead performance validation of power devices in DC/DC converter platforms, characterising switching losses, thermal behaviour, and dynamic response across operating conditions.
- Build deep customer and application knowledge — understanding how power MOSFETs are deployed across target end-markets and translating those insights back into product development priorities.
- Design, build, and iterate on evaluation boards to demonstrate device performance in representative converter circuits, creating compelling proof-of-concept platforms for customers and field teams.
- Conduct rigorous competitive benchmarking against key rivals, producing professional evaluation reports and application notes that clearly articulate differentiated performance.
- Develop high-fidelity simulation models — including system-level and device-level models — to support design-in activities and accelerate customer adoption.
- Author high-quality technical collateral including application notes, design guides, and white papers that position the product line as the reference choice in high-frequency applications.
WHAT WE'RE LOOKING FOR
Education
- MSc in Electrical Engineering as a minimum; PhD in power electronics or semiconductor devices strongly preferred.
Technical Expertise
- Solid grounding in power conversion topologies (synchronous buck, LLC, PSFB and related), power device physics, magnetics design, and control loop fundamentals.
- Hands-on prototype development experience at MHz switching frequencies — you are as comfortable with a soldering iron as with a simulation tool.
- Strong lab proficiency: oscilloscopes (including high-bandwidth probing for gate and switching-node measurements), function generators, electronic loads, and calorimetric loss measurement techniques.
- Practical simulation experience across two or more of: MATLAB/Simulink, SIMetrix, PSpice/LTspice, Ansys (Q3D, Maxwell, or Icepak).
- Familiarity with GaN or wide-bandgap device characteristics is a clear differentiator.
Professional Attributes
- Confident, clear communicator — able to present complex technical content to both engineering peers and non-technical commercial audiences.
- Collaborative by nature, with a track record of working effectively across engineering, marketing, and sales functions.
- Self-motivated and intellectually curious, with the initiative to drive projects forward in a fast-paced, matrixed environment.
WHY THIS ROLE
MHz DC/DC converter design is one of the most technically demanding and commercially significant areas in power electronics today — driven by AI infrastructure, advanced computing, and next-generation consumer and industrial platforms. This position places you at the forefront of that wave, with the resources, device portfolio, and customer access to do work that genuinely matters.
