ROLE DESCRIPTION

We are seeking a highly skilled Worst-Case Circuit Analysis (WCCA) Hardware Engineer to support detailed reliability and safety analysis of critical automotive electronic systems. The successful candidate will perform rigorous analytical evaluations to ensure circuit robustness under all operating conditions, tolerances, and environmental stresses, in compliance with automotive safety and quality standards (ISO 26262, AEC-Q100/200/300, OEM-specific requirements).

KEY RESPONSIBILITIES

Perform Worst-Case Circuit Analysis (WCCA) on safety-critical and mission-critical hardware circuits across 7 domains:

• LV house-keeping power supplies (switching regulators, LDOs)
• Isolated power supplies (flyback, forward, resonant converters)
• Analog sensing circuits (voltage, current, temperature)
• Digital logic circuits (gates, buffers, level shifters, clock/reset)
• HV FET gate driver circuits
• Contactor and pyro fuse driver circuits
• LV efuse circuits (semiconductor switches with overcurrent protection)

Build and validate circuit models and simulations (SPICE, MATLAB, or equivalent) for parametric sensitivity, aging, and tolerance studies.
Analyze process variations, temperature extremes, aging effects, and supply disturbances to determine design margins.
Collaborate with hardware design engineers to identify high-risk design areas, propose design mitigations, and optimize circuit robustness.
Document analysis results, compliance evidence, and traceability in line with automotive functional safety standards (ISO 26262).
Contribute to design reviews, FMEA sessions, and DFMEA alignment by providing WCCA evidence and margin analysis.
Interface with cross-functional teams including systems, validation, reliability, and safety to ensure comprehensive coverage of design risks.
Support customer reviews and audits with detailed WCCA reports and presentations.
