Member of Technical Staff, Release Engineer

Voice AI that resolves, not transfers. Most phone systems trap callers in menus and scripts. Vapi is the platform for deploying voice agents that know your business and can listen, adapt, and resolve in minutes. The numbers: 1 billion calls. 1 million developers. 10x enterprise ARR growth The customers: Amazon Ring, ServiceTitan, New York Life, Intuit, Kavak, and thousands more, from YC startups to the Fortune 500 The news: a $50M Series B led by Peak XV Partners, with Bessemer Venture Partners, Kleiner Perkins, M12 (Microsoft's Venture Fund), Y Combinator, and our earlier backers. Total raised: $72M Why We’re Hiring This Role: Vapi ships hundreds of pull requests a day while serving some of the world’s largest enterprises. Every release must stay fast, safe, observable, and predictable at scale. Our CI and deployment systems are critical product infrastructure. We need a senior/staff engineer to remove bottlenecks, repair fragile deploy paths, and increase confidence without slowing product teams. You’ll own the systems behind safe releases, including Argo CD, Terraform, and Atlantis—and automate the reliable path. This role focuses on CI/CD, testing, and deployment safety, not primary incident response. What You’ll Do: 30 Days: Map Vapi’s release architecture end to end. Partner with product and infrastructure engineers, baseline CI/test/deploy performance, identify the biggest failure modes, and ship an initial improvement. 60 Days: Own the release-tooling roadmap and operating health. Remove the costliest CI/deploy bottlenecks, improve observability and diagnosis, and automate slow or failure-prone workflows. 90 Days: Establish a repeatable model for safe, fast releases with measurable gains in validation time, deploy speed, and reliability. Deliver self-service workflows and guardrails, and set the longer-term release-infrastructure roadmap. Who You Are: Evidence of owning critical CI/CD or release infrastructure at meaningful scale and driving measurable cross-team improvements. We care about impact, not a specific number of years. Strong distributed-systems fundamentals and the ability to diagnose failures across build, test, deployment, and infrastructure layers. Hands-on experience operating Kubernetes-based delivery systems and infrastructure-as-code tooling such as Argo CD, Terraform, and Atlantis or comparable systems. A habit of automating repetitive work, investing in testing and passive defenses, and using data to prove that a system became faster or more reliable. Deep curiosity and the ability to gather context quickly, form a clear point of view, and keep pace as the architecture and product evolve. A low-ego teammate who communicates clearly and owns outcomes. Familiarity with AI coding tools is expected; experience as an SRE, with development frameworks like multi-agent workflows, and programming languages like TypeScript and Go are a plus. This is a full-time, hybrid role in San Francisco. How We Work: Build something worthy of love Craft matters. We aim to build products and experiences customers genuinely love, not just tolerate. Commit and follow through We finish what we start and build trust by being people others can count on. Why not today? We value urgency and momentum. The fastest path to customer value usually wins. Seek raw input We go directly to customers, data, and teammates instead of relying on summaries or assumptions. It’s our problem We operate as one team. We share credit, own mistakes together, and support each other when things get hard. Be direct and kind We give feedback clearly, respectfully, and without delay.
