In this role, you will take end-to-end ownership of services, domains, and critical systems, ensuring the reliability, scalability, security, and performance of the infrastructure supporting thousands of users across multiple products. You will have the opportunity to make meaningful technical decisions, contribute to our architectural direction, and work closely with development teams and other stakeholders to continuously improve our cloud environment and engineering practices. We are looking for someone who is comfortable working hands-on with infrastructure as code, independently troubleshooting complex technical issues, and sharing their expertise to support and mentor other engineers. The role reports to the DevOps Team Lead within the Cloud area., * Architecture & Cloud Infrastructure: Contribute to architectural decisions and the long-term evolution of our cloud platform, designing scalable, secure, and high-performance solutions across multi-account and multi-region AWS environments. * Infrastructure as Code: Build and maintain infrastructure using Terraform, defining standards for modules, versioning, state management, and reusable IaC practices across complex environments. * Platform Engineering & Automation: Evolve CI/CD practices, deployment strategies, and operational standards. Implement automation and GitOps workflows using tools such as Atlantis and ArgoCD. * Reliability & Problem Solving: Take ownership of complex and critical production issues, leading root cause and impact analyses and implementing sustainable solutions to prevent recurrence. * Observability & Monitoring: Define and improve logging, monitoring, and tracing practices, including SLIs/SLOs and distributed tracing, to strengthen platform reliability and visibility. * Security & Compliance: Implement and maintain platform controls supporting our security and compliance requirements, including ENS Nivel Medio and NIS2, in close collaboration with the SecOps team. * Cost Optimization: Drive cloud cost efficiency through appropriate governance, resource management, budgeting, and optimization practices across AWS environments. * Production & Disaster Recovery: Share ownership of production health and design resilient disaster recovery strategies, including RTO/RPO definitions and multi-region failover capabilities. * Cross-Team Collaboration: Partner with development teams and other technical stakeholders on architectural decisions, platform evolution, and engineering best practices, while helping guide and mentor less experienced team members.
