Subject: ENV-JD-001 · Hardware Design Engineer

Responsibilities

- Power-stage design — own switching power converters across the group's products: battery chargers, rectifiers, DC-DC stages and inverters for EV, energy-storage and solar applications, from topology selection and simulation through schematic, magnetics and prototype bring-up.
- Schematics and component engineering — schematic capture in Altium Designer or OrCAD, component selection at industrial and automotive grade, derating and worst-case analysis, and a BOM that survives supply-chain reality.
- Battery-system electronics — pre-charge, contactor drive, current sensing, isolation and insulationmonitoring circuits, and the interfaces between the battery management system, the power stage and the rest of the system.
- EMC and product safety — design to the IEC 61000 / CISPR EMC families and to IEC 62477-1, IEC

62619, IEC 62109 and the AIS-156 / ISO 26262 automotive families as each product requires; run pre-compliance in-house and manage certification-lab campaigns.
- Verification — plan and run design-verification tests on the bench (oscilloscope, power analyser, thermal camera, load banks)



and write the reports that go into the qualification file.
- DFM and release — drive layout reviews with the PCB designer and the contract manufacturer so boards release right the first time and cost what they were meant to cost.
- Cross-functional design — work with firmware, mechanical and electrical-integration engineers so the electronics, enclosure and control software are designed as one product.

What you must have

- Degree — B.E./B.Tech in Electrical or Electronics; M.Tech in Power Electronics is a plus.
- Experience — 4–8 years designing switching power converters above 1 kW (DC-DC, PFC, inverter or battery-charger stages) that reached production.
- Devices and magnetics — hands-on with Si/SiC MOSFETs and IGBTs, gate-drive design, inductor and transformer design, and loss and thermal budgeting.
- Tools — Altium Designer or OrCAD for schematic capture; LTspice, PLECS or PSIM for simulation.
- Standards — working knowledge of IEC 62477-1, IEC 62619 and the IEC 61000 EMC family; you have taken a product through a certification lab.
- Bench skills — comfortable debugging a live power stage with an oscilloscope and differential probes.

Positive to have

- GaN or SiC-based designs above 50 kHz; bidirectional or grid-interactive inverter experience (IEC

62109, IS 16221, IEEE 1547 or CEA grid-connectivity regulations).
- Exposure to AIS-156, ISO 26262 or a functional-safety development process (DFMEA, FTA).
- BIS, CE or UL certification experience on a shipping product.
- Python for automated bench testing; Git-based design revision control.
