Senior Platform Engineer, Cloud Infrastructure

Senior Platform Engineer, Cloud Infrastructure Type: Remote Coverage: Pacific Hours (8:00 AM – 5:00 PM PST) Job Description: We are looking for a senior engineer to build and operate the cloud-native platform that our products run on. This is a hands-on infrastructure engineering role: you will design and run production Kubernetes platforms, write and maintain the Go services and controllers that extend them, and own the reliability of systems that other engineering teams depend on. The work spans platform architecture, networking, observability, and production operations. You will write real code: Go services, Kubernetes controllers, custom middleware, but the value you create is measured in platform capability and reliability, not lines shipped. We are looking for someone who is comfortable owning ambiguous, multi-quarter initiatives and driving them to production. Key Responsibilities: Platform and Kubernetes Engineering: Design, build, and operate production Kubernetes clusters, including cluster networking, workload isolation, and multi-region topologies. Work with Kubernetes internals: resource quota management, scheduling and cluster behaviour, NetworkPolicy enforcement, and custom controllers or operators. Implement and operate service mesh capabilities: mTLS between services, service-account-level authentication and authorisation, and traffic management across internal and external request paths. Optimise containerised workloads for performance, cost, and resource efficiency. Software Development in Go, Python or Java: Write, refactor, and maintain production services, controllers, and middleware that extend the platform. Read and contribute to complex existing codebases, including open-source projects that we customise or extend. Build HTTP, REST, and gRPC service interfaces used by internal engineering teams. Write meaningful unit and integration tests, and treat testability as a design property rather than an afterthought. Reliability and Production Oper
