Who You Are A Platform Engineer / Builder who creates systems others depend on A team player and collaborator — you build with people, not around them Assertive and decisive — you propose, defend, and drive technical direction Mission-driven — you own problems end-to-end and deliver outcomes Innovative — you bring ideas and help the team adopt better ways of working AI-native engineer — you use AI assistants and agentic workflows daily Curious and continuous learner — growth is part of your job, not a side activity --------------------------------------------------------------- Our Environment You will operate in a modern AWS-based platform ecosystem: AWS Control Tower landing zone with guardrails and account vending AWS IAM Identity Center for federated access across accounts Multi-account AWS strategy (prod, staging, dev, sandbox, shared services, security, logging) Sandbox environments for experimentation with cost and security controls Multi-VPC architecture with Transit Gateway and VPC endpoints Amazon EKS as the primary runtime for platform and workloads GitOps delivery model with Argo CD Infrastructure as Code using Terraform / OpenTofu Crossplane-based control planes enabling self-service infrastructure APIs GitHub as a fully platform-owned surface (org, teams, repos, templates, governance) GitHub Actions for CI/CD, reusable workflows, OIDC to AWS, environment controls CI automation bots (PR validation, labeling, auto-assignment, auto-merge) Copilot org policies and AI development standards across repositories AI-augmented engineering workflows using Copilot and Claude JFrog Artifactory as the artifact backbone (registries, promotion, scanning, signing) ---------------------------------------------------------------- Key Responsibilities Platform Engineering (Core) - Build and evolve an internal developer platform (IDP) based on GitOps and Kubernetes - Design and deliver self-service infrastructure capabilities for product teams - Treat the platform as a product — developer experience is your primary metric - Contribute to IDP evolution using tools such as Crossplane, GitOps, and internal APIs - Maintain and extend Infrastructure as Code (Terraform / OpenTofu) - Deliver prototypes that evolve into production platform capabilities AI & Agentic Engineering - Use AI coding assistants daily (Claude, Copilot, or equivalent) - Design agentic workflows to automate platform operations (debugging, remediation, documentation, scaffolding) - Build AI-augmented tooling into the platform where it improves developer velocity - Define and raise the standard for responsible AI usage in engineering Cloud, AWS & Networking - Operate AWS services (EKS, IAM, S3, RDS, Lambda, CloudWatch) - Design and troubleshoot VPC architectures, routing, and multi-account networking - Work confidently with: -- CIDR planning, subnets, route tables -- Security groups, NACLs -- Transit Gateway, VPC peering -- Private connectivity via VPC endpoints -- DNS (Route53) - Debug Kubernetes networking (Ingress, Services, CNI, Network Policies) GitOps & Kubernetes - Operate Argo CD as a core delivery platform - Own multi-environment deployment strategies using ApplicationSets - Support progressive delivery (blue/green, canary where applicable) - Deploy, troubleshoot, and instrument Kubernetes workloads GitHub Platform Ownership - Manage GitHub organization as a platform product: -- Organization structure, teams, repositories, templates -- Branch protection, environments, review policies - Build reusable GitHub Actions workflows for platform-wide consumption -

Operate JFrog Artifactory (or equivalent systems at scale) - Manage registries (containers, Helm, language packages) - Define promotion flows across environments - Implement artifact security scanning, retention, and signing policies Collaboration & Leadership - Work cross-functionally with CloudOps, DevSecOps, FinOps, and SRE - Mentor engineers and contribute to technical direction - Drive adoption of platform standards across teams - Lead delivery of prototypes and platform capabilities - Communicate clearly and influence across engineering domains ---------------------------------------------------------------- Required Qualifications Must-Have - 7+ years in Platform Engineering, SRE, or closely related roles - Strong platform mindset (you build systems, not ticket queues) - Deep AWS experience (EKS, IAM, networking, core services) - Strong Kubernetes operational experience - Hands-on Argo CD / GitOps experience - Infrastructure as Code: Terraform / OpenTofu - CI/CD pipeline design experience (tool-agnostic) - GitHub administration at scale (organizations, workflows, governance) - Experience with artifact management systems (JFrog or equivalent) - Strong scripting skills (Python, Go, Bash, etc.) - Proven ability to work across teams and deliver outcomes Highly Desirable - Experience with IDP platforms (Backstage, Port, or similar) - Crossplane for Kubernetes-based infrastructure management - Argo ecosystem depth (Rollouts, Workflows, Events) - SRE practices: SLOs, SLIs, error budgets, incident response - DORA metrics and delivery performance tracking - Internal developer tooling or platform products Additional Nice-to-Haves - Observability: Datadog, Prometheus, Grafana, OpenTelemetry - Service mesh (Istio, Linkerd) - FinOps and cloud cost optimization - Policy-as-code (OPA, Kyverno) - Certifications (CKA, AWS, Terraform)
