Senior/Staff Platform Engineer

This position is listed on behalf of a partner company, who manages all applications and next steps. Our partner is looking for a Senior/Staff Platform Engineer based in Canada. The Senior/Staff Platform Engineer will build, operate, and evolve large-scale production infrastructure with a strong focus on Kubernetes and reliability. This hands-on role spans cloud infrastructure, Linux, networking, observability, CI/CD, automation, and production operations. You will diagnose complex infrastructure challenges across multiple technical layers and build tooling that improves reliability, scalability, and developer experience. The position offers significant autonomy, with ownership of ambiguous initiatives from initial design through implementation and production operation. You will work directly with technical stakeholders, contribute to architecture and reliability decisions, and take a leading role in critical incident resolution. Your impact will extend beyond day-to-day operations as you establish stronger engineering practices, automation, observability, and operational resilience. This is an ideal opportunity for a highly experienced engineer who combines deep systems expertise with strong technical judgment and communication skills. Accountabilities: - Design, build, operate, and continuously improve production Kubernetes platforms, owning cluster architecture, networking, workload isolation, resource management, security, upgrades, scaling, and reliability. - Troubleshoot Kubernetes and infrastructure issues beyond the application layer, including CNI and networking problems, scheduling, node behavior, resource constraints, controllers, and cluster-level failures. - Operate highly available infrastructure across cloud, hybrid, virtualized, and/or bare-metal environments, diagnosing complex issues across Kubernetes, containers, Linux, networking, and underlying infrastructure.

- Develop and maintain production tooling and automation using Go, Python, or Java to improve platform operations, deployment, troubleshooting, reliability, and developer experience. - Build internal services, APIs, integrations, and operational tools where needed, while applying sound software engineering practices such as testing, code review, maintainability, and documentation. - Own the reliability and operational health of critical production infrastructure, leading or significantly contributing to incident response, root-cause analysis, durable remediation, and disaster recovery initiatives. - Define and improve SLOs, SLIs, alerting, and operational processes, using logs, metrics, traces, profiling tools, and system-level diagnostics to improve availability, performance, capacity, resilience, and recovery times. - Build and maintain infrastructure as code using Terraform or equivalent technologies, creating reusable patterns and improving automation as the platform evolves. - Develop and improve CI/CD and deployment workflows while balancing delivery speed with reliability, security, scalability, and operational requirements. - Participate in cloud and infrastructure migrations, including dependency analysis, networking, cutover planning, rollback strategies, and production validation. - Build and enhance monitoring, dashboards, logging, distributed tracing, and alerting to improve incident detection, diagnosis, and recovery. - Work directly with customers, engineers, and technical stakeholders to understand requirements, investigate issues, communicate trade-offs, and drive effective technical solutions. - Own complex infrastructure initiatives from problem definition through design, implementation, and production operation, contributing to RFCs, architecture discussions, design reviews, and broader technical direction. - Mentor engineers and help strengthen engineering and operational practices while operating independently in ambiguous situations and taking ownership when immediate direction is unavailable.
