Role summary

You will act as the architect of the safety case: defining the top-level claims, argumentation structure, evidence strategy and assurance approach that connect product intent, system behaviour, AI performance, engineering controls, validation and operational deployment into a coherent safety argument. You will provide independent challenge and advice, while enabling Engineering and Product teams to own and deliver the safety evidence required for their systems.

Responsibilities

  • Own the safety case strategy and architecture for the organization's robotaxi and OEM ADAS products.
  • Define top-level safety claims, argumentation, evidence structures, and traceability from safety requirements through validation and deployment decisions.
  • Develop safety arguments appropriate for AI-enabled autonomous driving, incorporating functional safety, , AI safety, cybersecurity, validation, operational safety, and post-deployment monitoring.
  • Evolve reusable safety case approaches as the organization's products, vehicle platforms, and evidence base mature.
  • Partner with Product, Systems Engineering, AI/ML, Validation, Vehicle Engineering, Software, Hardware, and Operational Safety to define safety requirements and evidence expectations.
  • Identify gaps, assumptions, and weaknesses in the safety argument early and drive resolution with accountable teams.
  • Ensure product requirements, architecture, validation plans, and release criteria remain aligned with the safety case.
  • Support technical and programme leaders in making proportionate, evidence-based safety decisions.
  • Provide independent technical challenge of safety cases and supporting evidence.
  • Assess whether safety arguments are coherent, complete, evidence-backed, and sufficient to support release or deployment.
  • Highlight material gaps, uncertainties, dependencies, residual risks, and safety red lines.
  • Provide clear recommendations to safety governance forums and senior leadership.
  • Build a common understanding of safety case principles across the organization.
  • Coach engineering and product leaders on structured safety argumentation, evidence quality, and traceability.
  • Represent the safety case perspective in internal governance, customer, and technical discussions.
  • Contribute to the organization's broader safety strategy and assurance capability.

Requirements

  • Deep experience developing or owning safety cases for complex safety-critical systems, ideally in autonomous vehicles, ADAS, robotics, aerospace, defence, or another software-intensive domain.
  • Strong systems engineering background spanning requirements, architecture, verification, validation, and safety assurance.
  • Proven ability to translate complex technical evidence into structured safety claims and arguments.
  • Strong understanding of autonomous driving and AI/ML safety, including model performance, data, uncertainty, and limitations of conventional verification approaches.
  • Experience partnering with AI/ML, engineering, systems, and product teams on safety-critical products.
  • Strong knowledge of relevant standards, including , , ISO/PAS 8800, and ISO 3450x.
  • Excellent technical communication and stakeholder management skills.

Nice to have

  • Safety case experience with L2+/L3 ADAS or L4 ADS products.
  • Experience with GSN or equivalent structured assurance methods.
  • Safety evidence experience for end-to-end or foundation-model-based autonomous driving.
  • Experience working with OEMs, regulators, assessors, or independent safety reviewers.
  • Familiarity with operational and post-deployment safety monitoring.

What we’re looking for

  • You are an architect and systems thinker who can move comfortably between top-level safety strategy and detailed technical evidence.
  • You are pragmatic and able to distinguish between what is essential to the safety argument and what is merely desirable.
  • You are intellectually rigorous, curious and comfortable challenging assumptions, including established industry practice where it does not adequately address AI-enabled autonomous driving.
  • You can work independently of Engineering and Product without becoming detached from them: your role is to provide credible challenge, direction and oversight while helping teams succeed.
  • You are comfortable operating with uncertainty and can make clear recommendations based on the strength of the available evidence.
  • You are open to challenge and willing to change your position when better evidence emerges.
  • You can clearly articulate where you believe a safety red line exists, why it matters, and what evidence or mitigation would be required to move it.

Success in this role

  • A clear and credible safety case architecture exists for the organization's first robotaxi and OEM ADAS products.
  • Engineering and Product teams understand the safety claims they support and the evidence they are responsible for delivering.
  • Safety gaps and weak assumptions are identified early enough to influence product decisions rather than being discovered at the end of a programme.
  • The organization develops a safety argument for AI-enabled autonomous driving that is technically rigorous, scalable and capable of standing up to scrutiny from customers, regulators and independent assessors.
  • Senior safety and product governance has an independent, evidence-based view of whether the safety case is sufficiently strong to support release and deployment decisions.

Standards

  • ISO 26262 Road Vehicles - Functional Safety
  • ISO 21448 SOTIF - Safety of the Intended Functionality
