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
