Senior Platform Engineer

## About the role As a Senior Platform Engineer, your primary mandate is to manage our platforms to improve business continuity, best practices and contribute to the developer experience end-to-end, eliminating friction, accelerating onboarding to first contribution, and lifting productivity across the entire software delivery lifecycle. You will drive modernization and platform initiatives and steward high-leverage practices (Engineering, DevEx, SRE, DevSecOps, and AI-assisted engineering), operating both hands-on and strategically while partnering with executive leadership and guiding Staff/Senior engineers to deliver scalable, reliable, compliant, and cost-efficient solutions on AWS. Crucially, you will translate day-to-day developer needs into Golden Paths, opinionated tooling, and policy-backed workflows, enabling adoption through clear documentation, targeted training, and automated self-service capabilities. ## Key Responsibilities - Architectural Strategy: Define and steer medium and long-term architectural strategies for the platform, ensuring efficiency, scalability, and reliability across all AWS environments. - Platform as a Product: Codify architecture into practice by delivering reference implementations and Golden Path templates for high-performance builds and standardized scaffolding. - GitOps & Continuous Delivery: Engineer safe delivery and reusable GitHub Actions. Institutionalize GitOps using ArgoCD/Flux and Flagger for progressive rollouts (canary/blue-green) with automated, SLO-gated rollbacks. - Cloud-Native Orchestration: Manage and optimize Kubernetes operations using Karpenter for intelligent node provisioning, as well as HPA and KEDA for event-driven autoscaling. - Observability & SRE: Make observability the default through OpenTelemetry and New Relic. Define SLIs/SLOs, establish error-budget policies, and automate tracking of post-incident actions. - Security & Service Mesh: Raise cloud and service security, operate and propose improvements related to OAuth2/JWT and secrets
