Senior Electronics Engineer – Functional Safety

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.

Jobbeschreibung

Senior Electronics Engineer – Functional Safety

RIVR, an Amazon company, is building Physical AI by deploying autonomous robots for real-world doorstep delivery. Operating daily in diverse urban environments, RIVR's robots continuously learn from and navigate the millions of scenarios encountered during deliveries. By owning the full stack from software to hardware, RIVR is purpose-built for safety, reliability, and the customer from day one.

Key job responsibilities

• Design fault-tolerant circuits for safety-critical subsystems, selecting appropriate safety architectures (e.g., 1oo2, 1oo2D) 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.

Basic Qualifications

• 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.

Preferred Qualifications

• Experience with safety‑rated ICs (safe supply supervisors, safety MCUs, smart drivers with diagnostic feedback).
• Has contributed to or authored a Safety Manual for a hardware module.
• Familiar with Proven‑in‑Use argumentation for off‑the‑shelf components.
• PCB layout skills relevant to safety (creepage/clearance, redundant channel routing).
• Experience with circuit simulation (SPICE) to verify fault response behaviour.
• Experience in robotics, automotive, aerospace, or medical device sectors.
