The Opportunity
Ampere Recruitment is working exclusively with a VC-backed energy storage start-up building plug-in battery systems for homes and small businesses, aggregated into a virtual fleet for grid flexibility. Backed by founders with deep expertise in power electronics, energy storage, and grid systems, this is a genuine ground-floor opportunity. We are seeking a founding Power Electronics Engineer to own the full hardware architecture — from next-generation inverter development through to supplier management and mass production. The role can be scoped at Senior, Lead, or Principal level depending on experience.
Key Responsibilities
- Own end-to-end hardware architecture: inverter, BMS, battery pack, thermal management, protection, and communications interfaces
- Develop and evaluate advanced bidirectional converter topologies — DAB, cycloconverter, cascaded H-bridge, AC-coupled designs, and novel approaches
- Lead decisions on switching device selection (SiC/GaN), magnetic design, modulation strategy, control loops, EMI/EMC, and safety design
- Define product-level electrical specifications and translate commercial requirements into engineering constraints
- Review and validate supplier designs; select and qualify power semiconductors, magnetics, battery cells, and protection ICs
- Manage ODM/OEM suppliers and CMs through technical due diligence, factory visits, and manufacturing readiness
- Drive hardware from prototype through EVT, DVT, PVT, certification, and mass production
- Define and execute test plans covering safety, performance, efficiency, EMC, thermal, and grid-interface behaviour
- Ensure compliance with G98, IEC, and UL standards; collaborate with firmware teams on hardware–software interfaces
Requirements
- Degree in Electrical Engineering or Power Electronics; Masters/PhD advantageous
- Hands-on expertise in advanced bidirectional converter topology design
- Strong grasp of modulation strategies, magnetic design, control loops, EMI/EMC, and grid interface
- SiC and/or GaN device experience in high-efficiency converter applications
- Proficient in PLECS, MATLAB/Simulink, or LTspice; Altium Designer or equivalent for schematic/PCB
- BMS and Li-ion cell integration experience
- Proven track record from prototype to mass production; direct ODM/CM experience
