Responsibilities include:
- Scope, build, ship, and iterate on backend services and infrastructure that power our core product.
- Build scalable infrastructure for AI agent systems, dialer infrastructure, and intelligent pipelines that handle thousands of concurrent operations.
- Design and implement core backend systems including APIs, databases, event processing, and real-time data pipelines that support the product.
