The role emphasizes close collaboration with partners, architects, and senior engineers, with emphasis on correctness, verification tooling, and practical deployment in high-accountability environments. Location options include San Francisco, US or London, UK, with travel to customer sites and teams, and visa sponsorship available in both geographies.
