Platform Engineer (Senior)

Job Description

We are looking for a Platform Engineer to join our DevEx Platform team. You will help build and operate the internal platform that other engineering teams depend on – GitOps delivery, a Kubernetes-based runtime, infrastructure automation, and developer self-service.

This is a role for builders. We need someone who picks up a mission, drives it across teams, and ships outcomes – not tickets. You will work shoulder-to-shoulder with CloudOps, DevSecOps, FinOps, and SRE, and use AI and agentic AI as everyday tools to accelerate everything you do. We expect AI fluency, not curiosity.

Who You Are

• A team player who builds with people, not around them

• Assertive and decisive – you propose, defend, and drive technical direction

• Mission-driven – you finish what you start

• AI-native – you use AI assistants and agentic workflows daily to multiply your output

What You'll Do

• Build and operate the internal platform: GitOps delivery, Kubernetes runtime, infrastructure automation, and developer self-service

• Use AI coding assistants and agentic workflows to automate platform tasks – investigation, remediation, documentation, scaffolding

• Operate ArgoCD as a core platform capability: GitOps workflows, multi-environment delivery, ApplicationSets, progressive delivery

• Maintain and extend Infrastructure as Code (Terraform / OpenTofu) for platform components

• Manage the GitHub organization as a platform service: reusable Actions workflows, branch and environment protections, OIDC to AWS, CI bots, and Copilot org policies

• Operate JFrog Artifactory as the artifact backbone: registries, retention, promotion, and vulnerability scanning

• Design and troubleshoot AWS networking across multi-VPC topologies

• Collaborate with CloudOps, DevSecOps, FinOps, and SRE; mentor, and bring new tools and patterns to the team

What You'll Bring

Required:

• 7+ years in Platform Engineering, SRE, or closely related roles

• Platform mindset – you build platforms and self-service capabilities, not a ticket queue

• Hands-on daily use of AI coding assistants and agentic AI workflows

• AWS proficiency: EKS, IAM, S3, RDS, Lambda, CloudWatch

• AWS networking: VPC, subnets, CIDR planning, route tables, security groups, peering / Transit Gateway, VPC endpoints, Route53 — confident designing and troubleshooting multi-VPC topologies

• Kubernetes: strong operational proficiency deploying, troubleshooting, and instrumenting workloads

• ArgoCD & GitOps: multi-environment deployments, ApplicationSets, progressive delivery

• Terraform / OpenTofu

• CI/CD pipeline design (Azure DevOps, GitHub Actions, or both)

• GitHub as a platform: org/team/repo administration, reusable Actions workflows, OIDC to AWS, CI bots, Copilot org policies

• Artifact management: JFrog Artifactory or directly comparable (Nexus, GitHub Packages at scale)

• Scripting: Python, Go, Bash, or similar

Big advantages:

• IDP tools (Port, Backstage)

• Crossplane for Kubernetes-based infrastructure management

• Argo ecosystem depth (Rollouts, Workflows, Events)

• SRE practices (SLOs/SLIs, error budgets, incident response) and DORA metrics

• Experience building or operating internal AI-powered developer tools

A plus:

• Observability (Datadog, OpenTelemetry, Prometheus & Grafana)

• Service mesh (Istio, Linkerd), FinOps, Policy as Code (OPA, Kyverno)

• Certifications: CKA/CKAD, AWS Solutions Architect / DevOps / Advanced Networking, HashiCorp Terraform

If you are a team player, assertive, mission-driven, and you build with AI as a daily partner –⁠⁠⁠⁠ your place is with us.
