Senior Engineering Manager - Release Engineering San Francisco, CA, New York, NY, Portland, OR, or Remote within Canada or United States Every line of code that ships at Mercury passes through a gauntlet of builds, tests, and gates before it reaches our customers. On the surface, that process should feel seamless - frictionless for engineers, undetectable to users, and impossibly reliable. Behind that invisibility is Release Engineering. Mercury moves fast. We ship frequently, our monorepo grows daily, and the pressure to do it right never lets up. Release Engineering is the team that makes this possible: owning the CI/CD platform, build infrastructure, deployment tooling, and the practices that let 400+ engineers deliver with confidence. We're looking for an Engineering Manager to lead this team. You'll partner with the Backend Developer Experience team to deliver the full software delivery lifecycle from code commit to production, and build the engineering culture that keeps our release process a competitive advantage rather than a bottleneck. In this role you will: - Lead and grow a team of four engineers focused on CI/CD infrastructure, build systems, deployment automation, and developer tooling. - Create a strong culture of operational excellence, with measurable improvements to pipeline reliability, build times, and deployment confidence. - Own Mercury's release pipeline end-to-end - from pull request merge to production - ensuring it is fast, reliable, observable, and secure. - Drive the strategy and execution for improving build performance, test reliability, deployment safety (canaries, feature flags, rollbacks), and developer velocity. - Partner

We move quickly, we listen carefully, and we work alongside peers who hold us to the same standard we hold ourselves. THE ROLE You are Vera's senior clinical voice in Italy, the bridge between us and the medical societies, hospitals, and academic institutions whose members will use Vera. You are not running EHR integrations or compliance work. You are doing the part only a peer-credible clinician can do: opening doors, sitting in partnership meetings as an equal of the people we are trying to reach, and helping us understand how the local ecosystem actually works. WHAT YOU'LL DO - Make warm introductions to presidents and boards of national medical societies in Italy - Sit alongside
