• Gérer et faire évoluer notre environnement AWS (EC2, ECS Fargate, Lambda, S3) • Optimiser les coûts, la performance et la résilience • Construire et maintenir des pipelines de déploiement fiables • Mettre en place ou améliorer le monitoring, logging et alerting • Renforcer la sécurité de l'infrastructure et des données • Participer à l'optimisation de nos bases de données (MySQL, PostgreSQL, Redis, Elasticsearch) • Travailler main dans la main avec les développeurs et partager les bonnes pratiques

• Design, code, test and deliver software to automate manual operational work • Troubleshoot priority incidents, facilitate blameless post-mortems and ensure permanent closure of incidents • Engage with development team throughout the life cycle to help develop software for reliability and scale, ensuring minimal refactoring or changes • Identify application patterns and analytics in support of better service level objectives • Design self-healing and resiliency patterns • Design automated software and product upgrades, change management, and release management solutions • Participate in the 24×7 support coverage as needed • Mentor and guide junior developers

• Engineering the Platform: You’ll work hand-in-hand with product teams to lay the infrastructural groundwork for new apps. If it’s repetitive, you’ll automate it. If it’s fragile, you’ll harden it. • Killing Toil: You’ll identify the "friction points" in our dev lifecycle and build the Terraform modules or Python tooling to make them disappear. • Architectural Advocacy: You aren't a gatekeeper; you’re an enabler. You’ll champion sound software design and "paved road" patterns that allow devs to move fast without breaking things. • Observability over Monitoring: Moving us beyond simple alerts to deep introspection. You’ll help us use tools like Honeycomb and Grafana to understand *why* things happen, not just *that* they happened. • High-Agency Incident Response: You’ll help us evolve our incident remediation from "fixing the fire" to "learning from the heat," driving a culture of blameless retrospectives and systemic improvements.

• Design, implement, and maintain CI/CD pipelines and shared build tooling that improve throughput, reliability, and developer experience, with clear success metrics captured in Focals. • Deliver pipeline migrations (for example, Jenkins or Tekton to GitHub Actions) by creating automation, templates, guardrails, and documentation that reduces friction for service owners. • Diagnose and resolve CI incidents and performance bottlenecks through hands-on troubleshooting, root cause analysis, and follow-up improvements that prevent repeat issues. • Build and evolve Kubernetes-based automation workflows (for example, Argo Workflows) to reduce manual steps and standardize common delivery patterns. • Partner with internal stakeholders to understand requirements, set expectations, and communicate progress clearly, especially during high-impact changes. • Uphold security and compliance best practices across the delivery stack, including access controls, secrets handling, and infrastructure as code practices using Terraform.
