Opportunities in Tokyo, Japan

About Woven by Toyota Woven by Toyota is enabling Toyota’s once-in-a-century transformation into a mobility company. Inspired by a legacy of innovating for the benefit of others, our mission is to challenge the current state of mobility through human-centric innovation — expanding what “mobility” means and how it serves society.

Our work centers on four pillars: AD/ADAS, our autonomous driving and advanced driver assist technologies; Arene, our software development platform for software-defined vehicles; Woven City, a test course for mobility; and Cloud & AI, the digital infrastructure powering our collaborative foundation. Business-critical functions empower these teams to execute, and together, we’re working toward one bold goal: a world with zero accidents and enhanced well-being for all.

=========================================================================

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. ”

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 a senior 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.

Description of the responsibility that this position will be in charge of 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

Bachelor’s or Master’s in CS, EE, ME or related discipline 5+ 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

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
