About The Position

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.

Requirements

• 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

Nice To Haves

• 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

Responsibilities

• 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

Benefits

• Top-tier compensation: in order to get the best talent, we provide salary and equity that recognize your skillset
• Meals: free breakfast, lunch, and dinner provided in the office
• Healthcare: Comprehensive health, dental, and vision
• We have regular off-sites and team celebrations
