Stream | Amsterdam (NL), Skopje (North Macedonia)| Remote possible | Full Time | Visa Sponsorship We power real-time Chat, Video, Activity Feeds, and AI Moderation for apps like Strava, Bumble, eBay, and Patreon - billions of API requests per month, millions of concurrent users. We're looking for a hands-on Lead Engineer (Staff / Principal level) to own Platform & Infrastructure. Reports directly to the CTO. Small, senior team - you'll write code most of the time, not run a process org. First 6 months focus on three things with measurable outcomes: * Cloud cost optimization (AWS/GCP) — tooling and guardrails, not reports * Platform reliability and scalability — SLOs, observability, hardening * Architecture decisions on Kubernetes, databases, and cloud provider strategy Stack: Go, Python, AWS, GCP, Kubernetes, PostgreSQL, CockroachDB, Redis, Terraform. Looking for: software engineering background (Go or Python, not scripting-only), production cloud cost optimization experience, real distributed systems depth, and active AI tooling use in your engineering workflow. Not a fit if: you're security/compliance-heavy, scripting-only, or dependent on large-org support structures. Full JD + apply here: https://jobs.ashbyhq.com/stream/cbabbb5d-0e34-486b-acf7-ce40...
