## About the role

We are looking for a talented Founding Infrastructure Engineer to help build and scale our Voice AI Agent platform—a powerful system that autonomously interacts with customers, handling millions of conversations every month.

- Own the full lifecycle: architecture, implementation, deployment, and ongoing reliability
- Prototype rapidly, iterate with live interaction data, and continuously improve system performance and user experience
- Implement observability, monitoring, and operational best practices to ensure reliability in production, focusing on agent accuracy and latency
- Collaborate with engineers, product managers, and AI/ML scientists to deliver end-to-end features that power critical business outcomes
- 5+ years of professional software engineering experience with at least one modern language such as Go, Python, or Elixir
