Senior Platform Engineer (Crossplane)

This position is listed on behalf of a partner company, who manages all applications and next steps. Our partner is looking for a Senior Platform Engineer (Crossplane) based in Canada. The Senior Platform Engineer will design, build, and operate cloud-native infrastructure supporting a large-scale data platform processing approximately 400,000 pipelines every day. This hands-on engineering role focuses on production Kubernetes environments, infrastructure orchestration, and the development of scalable platform capabilities using Crossplane and Terraform. You will build reusable infrastructure services, controllers, and automation tools that empower engineering teams to provision and manage resources independently. Working across distributed systems, networking, observability, and cloud infrastructure, you will drive reliability, performance, and operational excellence. You will also take ownership of complex, long-term technical initiatives, from initial architecture and design through production implementation. This fully remote opportunity is ideal for an experienced platform engineer who combines strong software development skills with deep Kubernetes expertise and a passion for building resilient infrastructure. Accountabilities: You will take ownership of the architecture, development, and operation of production Kubernetes platforms and infrastructure orchestration systems, ensuring scalability, reliability, and efficient resource management across a complex data environment. Your responsibilities will include: - Design, build, and operate production Kubernetes clusters, including networking, workload isolation, cluster lifecycle management, and multi-region architectures. - Develop and extend infrastructure orchestration capabilities using Crossplane, Kubernetes custom resources, controllers, and operators. - Work with Kubernetes internals, including resource quotas, scheduling, NetworkPolicy enforcement, cluster behavior, and reconciliation patterns. - Build reusable, self-service platform capabilities that enable engineering teams to provision and manage infrastructure consistently. - Implement and operate service mesh solutions, including mutual TLS (mTLS), service-account authentication and authorization, and traffic management.

- Optimize containerized workloads for performance, cost efficiency, resource utilization, and reduced operational risk. - Develop, refactor, and maintain production services, Kubernetes controllers, operators, and platform middleware using Go, Python, or Java. - Build and maintain Kubernetes APIs, custom resources, reconciliation loops, and infrastructure templates. - Contribute to complex existing codebases, including open-source projects and customized platform components. - Develop REST, and gRPC interfaces supporting internal engineering teams. - Establish meaningful unit and integration testing practices to ensure the reliability and maintainability of platform services. - Lead incident response for platform-level issues, investigate root causes, and implement long-term corrective solutions. - Troubleshoot production Kubernetes infrastructure and distributed systems using logs, metrics, traces, and performance profiling tools. - Design resilient infrastructure with appropriate workload isolation, failure-domain boundaries, and blast-radius reduction. - Identify and resolve performance, capacity, and reliability challenges across distributed systems and data-intensive workloads. - Define and manage Service Level Objectives (SLOs), implementing actionable monitoring and alerting mechanisms. - Design and maintain reusable Terraform modules and Crossplane infrastructure abstractions for use across engineering teams. - Develop and improve infrastructure provisioning, orchestration, and delivery workflows using Crossplane, Terraform, and GitOps.
