Vapi (/ˈVɑːpi/): • Voice AI that resolves, not transfers • Powering 1 billion calls for companies like Amazon Ring, Intuit, ServiceTitan, and New York Life • Trusted by 1 million developers building the future of voice agents • Backed by Peak XV, Bessemer, Kleiner Perkins, M12, Y Combinator, and more with $72M raised • Try talking to Vapi now! Why this Role: • Vapi’s real-time voice platform depends on core infrastructure across compute, storage, networking, and telephony. As usage grows, reliability has to be designed into the systems our customers depend on. • We’re adding a dedicated SRE profile to our five-person Infrastructure team. We need a software-first engineer who can build tooling and automation, improve observability, and turn operational lessons into lasting engineering improvements. • This role has a distinct focus from our broader Infrastructure Engineer role because it requires deep reliability and operability judgment. You’ll join a calibrated team and work on latency-sensitive systems at meaningful scale. This role is based in San Francisco. What You’ll Do: • 30 Days: Learn Vapi’s architecture, production environment, incident history, and reliability practices. Build context with the Infrastructure and product engineering teams, then contribute an initial operational or reliability improvement. • 60 Days: Own a reliability workstream across observability, incident response, capacity, performance, or production automation. Reduce manual work and improve how the team detects, understands, and responds to failures. • 90 Days: Become the go-to owner for a meaningful part of Vapi’s reliability surface. Deliver a durable improvement to failure prevention or recovery, and propose a roadmap for the next reliability investments. Who You Are: • You are a senior or staff-level software engineer with meaningful SRE, production engineering, or infrastructure experience in distributed systems. • You write production-quality software and have built reliability tooling or automation yourself, rather than relying only on operational process. • You have deep experience with observability, incident response, failure analysis, capacity, and the practices that keep production systems healthy. • You are comfortable with Kubernetes, networking, and cloud infrastructure, and you can debug across application and infrastructure boundaries. • You reason clearly about failure modes and can balance reliability investments with product and engineering velocity. • Experience with real-time networking or telephony, Envoy, Postgres, Redis, Kafka, Aurora, ClickHouse, or a Google-style SRE environment is a strong plus. 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. Why Vapi: • Generational impact: Build the human interface for every business • Ownership culture: 70% of the company are previous founders • Kind team: The founders, Jordan and Nikhil, are Canadians • Tier-1 Investors: YC, KP seed, Bessemer Series A What We Offer: • Real stake: We offer a base salary of $280,000 to $314,000 and excellent equity ownership • Comprehensive health coverage: medical, dental, and vision plans • Team love: We love hanging out, and we do quarterly off-sites • Flexible time off: take what you need • More: catered meals, transportation, gym, and a $10k annual L&D budget
