Lead Platform Engineer

LEAD ENGINEER – PLATFORM & INFRASTRUCTURE ABOUT STREAM Stream powers real-time Chat https://getstream.io/chat/, Video https://getstream.io/video/, Activity Feeds https://getstream.io/activity-feeds/, and AI Moderation https://getstream.io/moderation/ for billions of end-users across thousands of apps — from Strava and Bumble to eBay and Patreon. Our platform processes billions of API requests per month and supports applications with millions of concurrent users, while delivering highly reliable, low-latency services and a great developer experience. The Role We're looking for a hands-on Lead Engineer to own Platform and Infrastructure at Stream. You'll work directly with a small, senior team and will be responsible for improving the efficiency, reliability, and cost profile of the systems powering Stream's entire real-time platform. This is not an architecture-at-a-distance role. You will write code most of the time, lead infrastructure decisions across teams, and shape how we operate at scale. Why This Role Exists Our platform works — but we're growing fast and there's meaningful work ahead on cost optimization, cloud efficiency, and platform scalability. The team needs a strong engineering leader who comes from a software engineering background, can own technical decisions independently, and can make infrastructure move faster without introducing big-org process dependencies. What You'll Work On Your first 6 months will focus on three areas: - Cloud migration (we're moving from AWS to GCP), with reservations. - Setting up Kubernetes, modernising our stack - Moving 35-40 Postgres shards from AWS RDS to self-hosted on Kubernetes. Beyond that, you'll shape long-term platform direction, define engineering standards, and collaborate with product and SDK engineers to keep the developer platform fast to build on.
