The title matters less than what you have built and run Depth in cloud infrastructure: Kubernetes, networking and infrastructure as code in production Experience improving developer experience is a strong plus, and an interest in security or observability is a welcome extra Time at a startup or scale-up, where you owned problems from start to finish Confidence to make calls, explain them clearly and push back when something looks wrong Curiosity across clouds and tools. We care more about how quickly you learn than which provider you know best Experience in regulated environments such as fintech, payments or identity is a plus Our platform runs on AWS and Kubernetes with Terraform, Postgres and RabbitMQ, alongside a Node.js and TypeScript product stack built on event sourcing.
