About The Client

Client is a Hero Electronix venture and a premier end-to-end silicon and systems partner with over 22 years of experience and 4,000+ employees across 12 countries. Serving over 90% of the world's top 20 semiconductor design firms, the company provides turnkey solutions ranging from design and verification to testing and embedded systems. About The Job:

- Experience Range: 5–10 Years (5+ Years Relevant Experience).
- We are looking for an experienced Hardware System Lead with strong expertise in power electronics, SiC MOSFET switching systems, high-voltage/high-current hardware design, gate-driver circuits, protection design, hardware interfaces, and validation.
- The role supports the development and validation of energetic power semiconductor test benches used for short-circuit, double/multi-pulse, and unclamped inductive load (UIL) test scenarios.
- This position is critical for ensuring safe, reliable, and robust operation of high-power SiC MOSFET dynamic test platforms.

Essential Job Functions:

- Lead system-level understanding and review of high-power semiconductor test hardware, including power paths, energy storage, switching stages, protection circuits, and control interfaces.
- Analyze DC-link capacitor banks, pre-charge/discharge circuits, load inductors, snubber circuits, high-current switching paths, and safe energy handling during normal and fault conditions.
- Review SiC MOSFET / IGBT switching behavior, including dv/dt, di/dt, voltage overshoot, ringing, parasitic loop impact, and safe operating margins.
- Review gate-driver designs including gate voltage levels, ON/OFF gate resistance, Miller clamp, negative gate bias, DESAT/overcurrent protection, soft shutdown, isolation, and CMTI margin.
- Analyze and improve fast protection circuits for high-energy test conditions including short-circuit protection, dI/dt and dV/dt fault detection, fault latch/reset, and safe shutdown strategies.
- Define hardware interface requirements for control boards and automation systems including signal conditioning, isolation, level shifting, relay/switch drive, feedback signals, interlocks, and diagnostics.




- Support board-level and system-level bring-up, debugging, root-cause analysis, validation planning, and robustness testing for high-power test systems.
- Provide hardware architecture reviews and design improvement recommendations.
- Develop validation plans, debug reports, and technical documentation.

Qualifications:

- 7–10 years of experience in power electronics hardware design, high-voltage/high-current systems, semiconductor test hardware, or high-power test instrumentation.
- Strong knowledge of SiC MOSFET and IGBT switching behavior.
- Strong expertise in gate-driver design, DC-link design, protection circuits, transient effects, and energy-flow analysis.
- Experience in schematic review, interface definition, signal conditioning review, isolation review, board bring-up, hardware debugging, and system-level validation.
- Ability to define test sequences and hardware-state transitions for automated test execution, including fault handling and safe-state behavior.
- Strong understanding of parasitic inductance/capacitance effects, grounding, signal integrity, EMC/EMI considerations, and connector/cable selection.
- Hands-on experience with high-voltage and high-current hardware systems.
- Knowledge of hardware interfaces and automation system integration.

Preferred Skills:
- Exposure to dynamic semiconductor test methods such as Double Pulse Testing (DPT), Short-Circuit Testing, Multi-Pulse Testing, UIL/Avalanche Testing, and High-Current Pulse Testing.
- Awareness of safety and interlock systems.
- Knowledge of CE/SEMI compliance readiness and validation practices for high-power equipment.
- Experience with simulation and design tools such as LTspice, PLECS, MATLAB/Simulink, Altium, Cadence, Mentor Graphics, or equivalent tools.

Education:




- Bachelor’s Degree in Electrical & Electronics Engineering (EEE), Electronics & Communication Engineering (ECE), or Power Systems.
- OR Master’s Degree in EEE, ECE, or Power Systems with 3+ years of relevant experience.
- OR PhD in EEE, ECE, Power Systems, or a related field with 2+ years of relevant experience.

Expected Deliverables:
- Hardware architecture reviews.
- Power path and energy-flow analysis reports.
- Gate-driver and protection circuit reviews.
- Hardware interface requirement specifications.
- Validation plans and testing strategies.
- Debugging and failure analysis reports.
- Design enhancement and reliability improvement recommendations.
