Safety Case

About the team

Our team owns the safety assurance argument for our autonomous vehicles — the structured case that says, with evidence, that our vehicles are safe to operate in their intended environment. We translate the work of engineering, safety, and operations teams into a coherent argument assessed against UL 4600 and aligned standards, and we carry that argument through the phase gates that govern how far we deploy: from operator-supervised driving toward fully driverless operation. Our output is what a third-party assessor reviews and what leadership relies on to make deployment-readiness decisions across the locations where we operate.

About the role

We are looking for a Safety Case Lead who will own the structure, content, and maturity of our safety case. You will architect the top-level safety argument, decompose it into claims and the evidence required to support them, and drive those claims from first draft to assessor-approved. The work is part systems thinking — building an argument that holds together across vehicle safety, operational, cybersecurity, and organizational dimensions — and part disciplined execution: tracking hundreds of claims and evidence items to a defensible state, on a schedule set by real phase-gate assessments. You will be the person who can stand in front of a third-party assessor and defend why the argument is sufficient, and the person who knows exactly where the gaps are before they do. This role is foundational; much of the safety case work depends on it being owned.

What you'll do

• Own the top-level safety case: the goal that vehicles are safe to operate, decomposed into pillars, claims, claim criteria, and supporting evidence.
• Architect the argument against UL 4600 or ISO 5083 and aligned standards (ISO 26262, ISO 21448/SOTIF, ISO 8800, AVSC best practices), mapping claims to the clauses they satisfy.
• Define what evidence each claim requires, and drive claims through the pipeline from identified to approved.
• Coordinate evidence production across engineering, safety, and operations pillars; resolve cross-pillar dependencies and surface epistemic defeaters before an assessor does.
• Prepare for and shepherd third-party safety case assessments at each phase gate (Vehicle operator to Driverless Operation).
• Own safety case traceability and tooling in Jama and YouTrack or other approved tools; keep evidence owned, current, controlled, and approved.
• Define and report metrics for safety case maturity and gate readiness to engineering and leadership.

What you'll need

• 8+ years in systems, functional safety, or safety assurance engineering, including direct ownership of or substantial contribution to a safety case or assurance argument for a safety-critical system.
