System Safety Engineer
TEAM
Product Integrity
We are the first-line of defense for safety + security + quality of AD/ADAS software at Woven by Toyota. Partnering with feature, systems, safety, cybersecurity and machine-learning teams, we turn prototypes into production-intent, standards-compliant software that can be trusted on public roads. Our mandate flows directly from Woven’s commitment to “zero accidents and enhanced well-being for all.”
WHO WE ARE LOOKING FOR
A systems-minded safety engineer who can turn safety goals into a concrete, verifiable design that ships. You thrive at the intersection of system architecture and implementation: allocating safety requirements, defining technical safety concepts, and ensuring the right mechanisms, monitors, and validations exist in software to meet safety targets. This is an individual contributor role with deep hands-on engagement across AD/ADAS feature teams, Systems Engineering, V&V, and ML Safety. You bring rigor, traceability, and practical judgment to make our internal product demonstrably safe for mass production.
RESPONSIBILITIES
Allocate safety requirements (system → software component) with clear interfaces, state machines, timing/resource budgets, and acceptance criteria.
Define and guide implementation of safety mechanisms (e.g., diagnostics, redundancy, watchdogs, plausibility checks, safety envelope monitors, degraded modes/safe states) and ensure their effectiveness is verified.
Partner with V&V to design safety verification strategies (unit/integration/system/HIL/vehicle), derive objective pass/fail criteria and safety KPIs, and ensure evidence completeness for the Safety Case.
Contribute evidence and risk assessments to the Safety Case and present rationale/evidence to internal/external stakeholders and auditors.
Lead/participate in analyses (FMEA/FMEDA, FTA, interface hazard reviews, resource/timing analyses) and feed findings into design updates and confirmation measures.
Collaborate tightly with Safety Architecture (for HARA/goal setting/ASIL decomposition), Systems Engineering (for architecture cohesion and ICDs), ML Safety (for data/ODD/monitoring strategies), and Cybersecurity (for safety-security co-engineering).
Drive change impact analysis for CRs, deviations, and waivers to preserve safety intent and traceability across releases.
Conduct focused reviews on requirements, designs, and test plans to close gaps quickly.
MINIMUM QUALIFICATIONS
Bachelor’s or Master’s in CS, EE, ME or related discipline.
3+ years in safety-critical automotive or aerospace systems in a production environment.
Demonstrated ownership of technical safety concepts and requirement allocations that went to production ECUs.
Deep, practical experience with ISO 26262 (esp. Parts 3-6) and familiarity with SOTIF (ISO 21448).
Hands-on collaboration with V&V, including HIL/vehicle test design, coverage tactics, and KPI definition.
Working knowledge of embedded software fundamentals (C/C++ reading proficiency, Python for analysis/prototyping), and common automotive interfaces (CAN, SOME/IP)
Excellent cross-functional communication, influence, and documentation skills.
NICE TO HAVES
Experience with assurance cases and/or risk management
Functional Safety Professional or AI Safety Professional certification (TUV/UL or equivalent).
Experience in in-vehicle functional safety (ISO 26262).
ASPICE Process Expert / Provisional Assessor or equivalent.
Japanese language proficiency or experience working with Japanese OEM/Tier-1 partners.
