Staff Functional Safety Engineer

San FranciscoOn-siteFull-time

AI Summary

A staff function-al safety engineer owns the safety lifecycle for autonomous vehicles, from hazard analyses to safety evidence packages, ensuring traceable safety across HW/SW and operations.

About this role

About Humble Robotics
Working at Humble Robotics means taking on the biggest change in ground transportation in decades. We’re building an autonomous, zero-emissions hauler that dramatically lowers the cost of freight with groundbreaking vision-based AI, designed for today’s global logistics network.
We’re a fast-moving, close-knit team of AV industry veterans and innovative thinkers. We don’t believe culture can be engineered – but when it falls into place, it’s a once-in-a-lifetime adventure.
Progress has never felt so present.
Position Overview
This role owns the functional/system safety engineering foundation end-to-end: hazard analysis, safety requirements, safety case/evidence, and the verification strategy across simulation and vehicle testing. You’ll work directly with autonomy, vehicle platform, embedded/compute, simulation, and test to ensure safety is designed in and proven with traceable evidence—without building a heavyweight process.

Key Responsibilities

  • Own the safety lifecycle for the AV program: safety plan, safety case structure, evidence strategy, and readiness gates.
  • Lead safety analyses across the stack (e.g., HARA, FMEA, FTA and other system-level hazard analysis approaches as appropriate) and maintain the hazard log.
  • Define safety goals, safety concepts (functional/technical or system safety equivalents), and safety requirements for HW/SW/ops with clear verification methods.
  • Drive safety-critical architecture and design decisions: fault handling, monitoring/diagnostics, degraded modes, minimal-risk behaviors, and interface assumptions.
  • Build the verification strategy linking hazards and safety goals to simulation coverage, SIL/HIL where applicable, and on-road/track testing.
  • Ensure traceability from requirements to tests to results, and produce clear safety evidence packages for internal reviews and external partners.
  • Establish lightweight operating mechanisms: safety reviews, change impact assessment, safety issue triage, and release/readiness decision documentation.
  • Guide teams on practical application of relevant standards and best practices (e.g., ISO 26262 where applicable, ISO 21448/SOTIF, UL 4600).

    • Minimum Qualifications

  • 8+ years building safety-critical systems (automotive, robotics, aerospace, industrial, medical), including 5+ years in functional safety and/or system safety.
  • Strong track record owning safety artifacts through major milestones: hazard analyses, safety requirements, verification strategies, and safety evidence.
  • Systems engineering strength: crisp, testable requirements; interface management; traceability; risk-based decision-making.
  • Technical breadth across AV-relevant domains (vehicle interfaces/actuation, embedded/compute, autonomy behaviors, operational constraints).
  • Comfort working hands-on with data and engineering tooling (e.g., Python/SQL) to create and interpret readiness signals.
  • Clear communicator who can lead cross-functional technical reviews and drive alignment.
  • Eligible to work in the United States

    • Preferred Qualifications

  • Direct L3/L4 autonomy experience (driverless pilot or commercial launch).
  • Practical experience applying ISO 26262, ISO 21448 (SOTIF), and/or UL 4600 to complex systems.
  • Experience with fault-tolerant/fail-operational strategies and minimal-risk maneuvers for automated driving.
  • Experience with HIL/SIL and simulation scenario coverage design tied to safety claims.
  • Experience working with partners, auditors, or regulators on safety evidence.

    • Compensation

    Salary ranges are determined by role, level, and location. Within the range, individual pay is determined by additional factors, including qualifications, skills, experience, and location. We also offer competitive equity compensation and benefits.
