6B13: Senior Platform Engineer

Key Responsabilities

• 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 lifecycle management (Secrets Manager/KMS). Implement Policy-as-Code adoption across CI/CD and Kubernetes admission controllers.
• Event-Driven Excellence: Design and operate event topologies covering Kafka partitioning, compaction, retention policies, and schema evolution, including performance and reliability.
• AI-Assisted Engineering: Promote the adoption of AI-assisted practices to enhance code quality, automated refactoring, automated operations, and technical documentation.
• FinOps & Efficiency: Drive cost-aware architecture through cloud computing best practices, scalability, and platform/service efficiency, not merely focusing on savings plans or reservations.
• Technical Governance: Implement governance and controls that ensure the correct management of services, security, and compliance of our platforms and technologies, contributing to a culture of excellence.
