### Business Segment Overview

Engage in a deep variety of business-critical activities that keep our company running efficiently. From strategic marketing and financial management to human resources and operational oversight, you’ll have the opportunity to optimize processes and implement game-changing policies.

### Responsibilities

Position Purpose: As a Senior Container Engineer on the Containers team, you’ll build, run, and continuously improve our Kubernetes platform, the foundation for application delivery. You’ll work hands-on with cluster operations, networking, ingress, storage, and core platform services, partnering closely with development, security, and operations teams to support day-to-day platform needs and drive automation through infrastructure as code and CI/CD.

Using cloud-native and open-source tools, you’ll help keep the platform scalable, reliable, and secure while improving performance and developer experience so teams can ship faster and with confidence. This is a highly hands-on role where your work directly shapes developer experience and platform reliability, enabling teams across the company to ship faster, safer, and on a scale.

Primary duties will include: Operate and maintain Kubernetes platforms (Rancher/RKE2 or AKS), including upgrades, scaling, performance tuning, backups, and HA patterns. Contribute to automation and golden paths by enhancing Terraform modules, Helm/ Kustomize templates, GitHub Actions workflows, and self-service onboarding. Implement and support GitOps workflows with Argo CD, including safe deployments, rollbacks, and drift detection.

Assist with container supply chain and registry management (ACR), including immutability and vulnerability scanning. Help maintain platform observability (Datadog/Prometheus, Graylog /Splunk) through dashboards, alerts, and basic SLOs. Partner with development and infrastructure teams for onboarding, troubleshooting, documentation, and incident response; participate in an on-call rotation. Follow established security and compliance guardrails (RBAC, secrets management, change controls).

### Qualifications

To land this role you will need: 3+ years in Platform, SRE, or DevOps roles with hands-on production Kubernetes experience. Experience with GitOps and modern CI/CD tooling (e.g., Argo CD, GitHub Actions, Azure DevOps). Working knowledge of Infrastructure as Code (Terraform), packaging (Helm/ Kustomize), and Linux/networking fundamentals. Scripting experience (Bash and/or Python) and comfort with YAML-driven workflows.

Experience troubleshooting distributed systems using logs, metrics, and traces.

### What makes you stand out

Deep e xperience with Rancher/RKE2 or AKS in production environments. Policy-as-code leadership ( Kyverno /Gatekeeper), supply chain security (cosign, SBOMs). ACR governance, artifact promotion strategies, and hardened self-hosted runners. Experience designing or operating SOX/SOC-aligned CI/CD controls and evidence pipelines. Experience integrating AI/ML-driven automation into containerized infrastructure and DevOps workflows.
