Senior Electronics Engineer – Functional Safety, SIL 2/3 Expert

Amazon Inc.; Zürich; Vor Ort; CHF 110.000 - 150.000; Vollzeit

Zusammenfassung

Amazon Inc.'s RIVR unit seeks a Senior Electronics Engineer – Functional Safety to design fault-tolerant electronics for safety-critical subsystems, perform FMEDA, and certify hardware to SIL targets. You will collaborate with firmware, systems, and mechanical teams to embed safety across the robot.

This role requires a Master’s in Electrical Engineering and 5+ years of hardware design experience in safety-certified products, with hands-on experience in safety architectures, SIL calculations,

Qualifikationen

• 5+ years designing electronics hardware for Functional Safety–certified products.
• Proven work under IEC 61508 (preferred), ISO 13849, or ISO 26262.
• Delivered PCB-level hardware that achieved SIL 2 or SIL 3 (or equivalent PL d/e, ASIL B–D) certification.
• Background in analog, power, and/or mixed-signal circuit design.
• Hands-on experience implementing safety architectures in schematics — not just block diagrams.
• Ability to perform FMEDA and SIL metrics calculations on your own designs.
• Understanding of failure rate data sources and component derating for reliability.
• Strong problem-solving skills and ability to debug fault-tolerant hardware.
• Comfortable working cross-functionally with firmware, mechanical, and systems teams.
• Master’s degree or higher in Electrical Engineering, Electronics, or a closely related field.

Aufgaben

• Design fault-tolerant circuits for safety-critical subsystems, selecting appropriate safety architectures based on the required SIL target.
• Implement hardware diagnostic and monitoring mechanisms to detect dangerous failures.
• Design circuits that enforce a defined safe state when a fault is detected.
• Apply Common-Cause Failure mitigation techniques at the component and PCB level.
• Perform FMEDA on your own schematics — identifying failure modes per component and calculating Safe Failure Fraction (SFF) and Diagnostic Coverage (DC).
• Build Reliability Block Diagrams and compute SIL metrics to verify your designs meet the target.
• Select and derate components based on failure rate data, mission profiles, and expected lifetime.
• Advise system architects on hardware safety constraints and review PCB layouts for safety compliance.
• Collaborate with electronics, firmware, and systems engineering teams to integrate safety functions into the overall robot design.
• Create and maintain Functional Safety documentation for your hardware modules.
