Team Overview

Managed Kubernetes is part of Target Infrastructure Services providing the foundational container platform for deploying and operating applications across Target data centers and public cloud environments. The platform enables engineering teams to build and operate scalable reliable services without having to manage the complexity of the underlying Kubernetes infrastructure. Through API- and UI-driven automation teams can provision upgrade and manage Kubernetes clusters at scale across on-premises and cloud environments. The platform also provides curated capabilities for security observability compliance and resiliency. By providing a consistent Kubernetes experience across Target data centers and public cloud Managed Kubernetes reduces operational complexity improves reliability and accelerates application and platform development across Target.

Position Overview

We are looking for a Senior Engineer Managed Kubernetes Platform to design build and operate reliable cloud-native platform capabilities across public cloud hybrid cloud and on-premises this role you will own Kubernetes platform components and problem spaces end-to-end independently solve complex technical and operational problems and partner with product and engineering teams to deliver secure scalable and easy-to-use platform services. You will bring deep Kubernetes and platform engineering expertise improve how the platform performs in production and help other engineers grow through technical guidance and constructive feedback.

Responsibilities

• Own Kubernetes platform services or components through design implementation deployment and production operation; make sound decisions that balance customer needs reliability security maintainability and delivery constraints.
• Build and maintain platform automation tooling controllers and services primarily using Go (Golang) and contribute production-quality code with appropriate tests and clear operational behavior.
• Provision configure upgrade troubleshoot and optimize Kubernetes clusters and supporting infrastructure across cloud hybrid and on-premises environments including Google Kubernetes Engine (GKE) where applicable.
• Design and improve Kubernetes networking and connectivity including CNI ingress services network policies load balancing traffic routing and service-to-service communication.
• Automate infrastructure and platform changes using Infrastructure as Code and Kubernetes tools such as Terraform Helm and Kustomize; implement and improve GitOps workflows with Argo CD and/or Flux.
• Improve platform observability and operations through useful metrics logs traces dashboards alerts health indicators and service thresholds; use production data to identify patterns and drive reliability and performance improvements.
• Design for failure and recovery by establishing clear failure boundaries applying retries timeouts and other appropriate resilience patterns and ensuring services degrade gracefully.
• Participate in and independently manage incidents for owned systems coordinate investigation and resolution communicate status clearly and follow through on root-cause analysis and reliability improvements.
• Apply secure-by-default practices to platform services and automation understand relevant threats manage secrets appropriately remediate findings and work with security and platform partners on effective controls.
• Lead technical discussions within the team and collaborate with partner teams on multi-component designs integrations operational improvements and delivery of platform capabilities.
• Review code and designs with a focus on quality testability security and operational risk; provide coaching-oriented feedback and mentor engineers in Kubernetes and platform engineering practices.
• Document technical evaluations decisions runbooks and operational procedures so that engineers and stakeholders can understand and support the platform.
