## About the Role

Artificial Intelligence (AI), Research Laboratory, Customer Support/Service, Logistics, Healthcare, Machine Tool, Cloud Computing, Incident Response, Production Systems, Process Improvement, * Strong experience with cloud infrastructure - GCP, AWS, or Azure - and containerized deployments (Docker, Kubernetes)

 * Proficiency with infrastructure-as-code tooling (Terraform or equivalent)
 * A track record of improving reliability and developer experience in high-throughput, latency-sensitive systems
 * Ownership mindset: you don't wait to be asked and you see problems through to the end
 * Comfort dropping below the abstraction layer - able to debug at the level of bits and bytes when it's called for
 * Strong system design instincts - clean architecture, high availability, and as few moving parts as possible
 * A track record of driving performance at scale - pushing requests-per-second toward best-in-class efficiency

Nice To Have

 * Experience with real-time or streaming systems (WebSockets, WebRTC, or similar)
 * Familiarity with ML/AI infrastructure - model serving, GPU workloads, or inference optimization
 * Strong proficiency in TypeScript and Python
 * You are a former founder

## Description

As a Platform Engineer at Phonic, you'll build the foundation that lets our engineering team move fast without breaking things. Real-time voice AI at our scale is unforgiving - latency is visible, reliability is everything, and our systems need to perform flawlessly across hundreds of thousands of mission-critical calls every day. You'll own the infrastructure, tooling, and deployment systems that make that possible, freeing our backend and research teams to focus on pushing the frontier., * Design and maintain the core infrastructure that powers Phonic's real-time voice AI platform - cloud infrastructure, deployment pipelines, and observability systems

 * Build internal tooling and abstractions that improve engineering velocity across the team
 * Own reliability and performance at scale - define SLOs, instrument monitoring, and lead incident response when things go wrong
 * Partner closely with backend engineers and researchers to translate cutting-edge AI capabilities into production-ready systems
 * Drive improvements to how we build, test, and ship software - reducing friction across the entire development lifecycle
