Stream is a Saudi Arabia-based fintech that provides billing and payments infrastructure for businesses across MENA.
Stream powers real-time Chat, Video, Activity Feeds, and AI Moderation for billions of end-users across thousands of apps, processing billions of API requests per month. This is a full-time job opening based in Amsterdam or remote in Europe/EU. Hybrid policy: applicants based in the Netherlands or relocating here are expected to work in the office in Amsterdam 3 times per week. Exemptions may apply to specific cases. Relocation and visa sponsorship is possible. WHAT WILL YOU WORK ON As a Senior Infrastructure Engineer, you join a small, senior platform team during a period of significant change: an AWS to GCP migration, a move to Kubernetes, and the relocation of 35-40 Postgres shards from managed RDS to self-hosted. This is a hands-on role: you will write code most of the time, own infrastructure decisions independently, and work without the support structures of a large organisation. Success looks like systems that scale predictably under load, cloud spend that falls per unit of traffic, and migrations that land without incident. Job Responsibilities - Design, build, and operate infrastructure for high-scale real-time systems handling millions of concurrent connections and billions of monthly API requests. - Drive Kubernetes work end-to-end: cluster architecture, workload design, and migration of existing services, rather than operating clusters someone else designed. - Contribute to the AWS-to-GCP migration, including re-architecting workloads for cost and performance rather than lifting and shifting. - Own cost and efficiency optimisation across cloud infrastructure, identifying levers and measuring outcomes against real spend and utilisation data. - Write production Go and Python: internal services, platform tooling, and automation that improve how product and SDK engineers deploy, observe, and debug. - Lead post-migration tuning and capacity planning, closing the loop between architectural decisions and production behaviour. - Partner with backend, video, and moderation engineers on system design, reliability targets, and tradeoffs that span service boundaries. - Participate in on-call, incident response, and root cause analysis, turning findings into durable fixes rather than one-off patches. ABOUT YOU You have - 5+ years in infrastructure, platform, DevOps, or SRE engineering, with clear depth in infrastructure over application development. - Software engineering background: you have built systems, not only configured them. Production coding experience in Go or Python; scripting-only backgrounds are not a fit. - Kubernetes experience at a meaningful production scale that goes beyond operations: you have driven cluster strategy, designed workloads, or led a migration. - Demonstrated cloud cost or efficiency optimisation at scale, on AWS or GCP - Direct experience running high-scale, high-load production systems. - Strong cloud fundamentals of networking, compute, storage, IAM and the habit of asking why a system behaves as it does rather than accepting defaults. - Hands-on in a small team: comfortable leading a project and reviewing a PR in the same week, without large-org support structures. - Active use of AI tooling in your engineering workflow: applied adoption, not familiarity. Bonus points - Experience across both AWS and GCP; cloud migration experience between providers is a strong plus. - Large-scale PostgreSQL knowledge: sharding, replication strategy, or partitioning tradeoffs, ideally self-hosted. - Background with real-time systems — WebSockets, WebRTC, streaming, or persistent-connection workloads. - Familiarity with the wider stack: CockroachDB, Redis, Terraform, and a Prometheus-based observability stack. - Prior experience at an API-first or infrastructure-enabling scaleup.
