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 Canadian …
