Founding Senior Engineer (Infrastructure)

Mission

The Founding Senior Engineer (Infra) will be responsible for scaling Vapi’s real-time conversational infrastructure to millions of concurrent calls, while ensuring every call gets picked up within 1s with 99.9% reliability. You’ll also be a foundational part of how we build the culture at Vapi.

Outcomes

1. Own scalability projects end-to-end

   • Ship a pre-scoped project within the first 7 days (e.g., redis HA)

   • Ship a project independently within the first 30 days (e.g., new CRD for managing worker pools)

2. Build monitoring

   • Ship pre-defined monitoring goals within the first 14 days (e.g., prometheus rules)

   • Ship monitoring independently within the first 30 days (e.g., refactor call monitoring to real-time alert on latency spikes)

3. Build anti-fragility into the infrastructure

   • Unprompted, build things that make our infrastructure more antifragile (e.g., auto multi-cluster rollover).

Competencies

• Experience with Kubernetes, Pulumi, or scaling other distributed systems

• Communication: You can clearly articulate what you’re thinking and feeling

• Cracked-ness: You’re more cracked than the most cracked person on the team

• Startup Ready: You have a reason to be here and can make sacrifices for something uncertain

• Founder Juice: New ideas come from you, you build it yourself or annoy everyone until it’s done ;)
