Senior Platform Engineer

If you are a mission-driven engineer who builds systems, embraces AI as a core tool, and thrives in complex distributed environments — your place is with us. Who You AreA Platform Engineer / Builder who creates systems others depend onA team player and collaborator — you build with people, not around themAssertive and decisive — you propose, defend, and drive technical directionMission-driven — you own problems end-to-end and deliver outcomesInnovative — you bring ideas and help the team adopt better ways of workingAI-native engineer — you use AI assistants and agentic workflows dailyCurious and continuous learner — growth is part of your job, not a side activity Our EnvironmentYou will operate in a modern AWS-based platform ecosystem: AWS Control Tower landing zone with guardrails and account vendingAWS IAM Identity Center for federated access across accountsMulti-account AWS strategy (prod, staging, dev, sandbox, shared services, security, logging)Sandbox environments for experimentation with cost and security controlsMulti-VPC architecture with Transit Gateway and VPC endpointsAmazon EKS as the primary runtime for platform and workloadsGitOps delivery model with Argo CDInfrastructure as Code using Terraform / OpenTofuCrossplane-based control planes enabling self-service infrastructure APIsGitHub as a fully platform-owned surface (org, teams, repos, templates, governance)GitHub Actions for CI/CD, reusable workflows, OIDC to AWS, environment controlsCI automation bots (PR validation, labeling, auto-assignment, auto-merge)Copilot org policies and AI development standards across repositoriesAI-augmented engineering workflows using Copilot and ClaudeJFrog Artifactory as the artifact backbone (registries, promotion, scanning, signing) Key ResponsibilitiesPlatform Engineering (Core)Build and evolve an internal developer platform (IDP) based on GitOps and KubernetesDesign and deliver self-service infrastructure capabilities for product teamsTreat the platform as a product — developer experience is your primary metricContribute to IDP evolution using tools such as Crossplane, GitOps, and internal APIsMaintain and extend Infrastructure as Code (Terraform / OpenTofu)Deliver prototypes that evolve into production platform capabilitiesAI & Agentic EngineeringUse 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 velocityDefine and raise the standard for responsible AI usage in engineeringCloud, AWS & NetworkingOperate AWS services (EKS, IAM, S3, RDS, Lambda, CloudWatch)Design and troubleshoot VPC architectures, routing, and multi-account networkingWork confidently with:CIDR planning, subnets, route tablesSecurity groups, NACLsTransit Gateway, VPC peeringPrivate connectivity via VPC endpointsDNS (Route53)Debug Kubernetes networking (Ingress, Services, CNI, Network Policies)GitOps & KubernetesOperate Argo CD as a core delivery platformOwn multi-environment deployment strategies using ApplicationSetsSupport progressive delivery (blue/green, canary where applicable)Deploy, troubleshoot, and instrument Kubernetes workloadsGitHub Platform OwnershipManage GitHub organization as a platform product:Organization structure, teams, repositories, templatesBranch protection, environments, review policiesBuild reusable GitHub Actions workflows for platform-wide consumptionOperate CI automation (PR checks, labeling, merge automation)Define Copilot governance and AI usage standards across repositoriesEnsure secure OIDC integration between GitHub and AWSArtifact ManagementOperate JFrog Artifactory (or equivalent systems at scale)Manage registries (containers, Helm, language packages)Define promotion flows across environmentsImplement artifact security scanning, retention, and signing policiesCollaboration & LeadershipWork cross-functionally with CloudOps, DevSecOps, FinOps, and SREMentor engineers and contribute to technical directionDrive adoption of platform standards across teamsLead delivery of prototypes and platform capabilitiesCommunicate clearly and influence across engineering domains Required QualificationsMust-Have7+ years in Platform Engineering, SRE, or closely related rolesStrong platform mindset (you build systems, not ticket queues)Deep AWS experience (EKS, IAM, networking, core services)Strong Kubernetes operational experienceHands-on Argo CD / GitOps experienceInfrastructure as Code: Terraform / OpenTofuCI/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 outcomesHighly DesirableExperience with IDP platforms (Backstage, Port, or similar)Crossplane for Kubernetes-based infrastructure managementArgo ecosystem depth (Rollouts, Workflows, Events)SRE practices: SLOs, SLIs, error budgets, incident responseDORA metrics and delivery performance trackingInternal developer tooling or platform productsAdditional Nice-to-HavesObservability: Datadog, Prometheus, Grafana, OpenTelemetryService mesh (Istio, Linkerd)FinOps and cloud cost optimizationPolicy-as-code (OPA, Kyverno)Certifications (CKA, AWS, Terraform) Gross Salary€7,000–€9,000
