• Design and implement resilient, secure, and scalable cloud environments to support client platforms in production. • Drive production readiness and operations: monitoring and alerting, incident support, runbooks, capacity planning, reliability improvements, and release readiness. • Build and maintain CI/CD workflows and reconfigure/enhance an existing proprietary pipeline using Argo. • Automate infrastructure provisioning and configuration using Infrastructure as Code (Terraform, CloudFormation, CDK). • Support containerized deployments and orchestration using Docker and ECS. • Develop automation scripts and utilities in Python and/or Bash for deployment, configuration, and operational tasks. • Implement and maintain service configuration and deployment automation across environments (dev/test/stage/prod). • Configure and manage cloud networking and access controls, including Security Groups. • Implement and maintain monitoring/observability capabilities (metrics, logs, traces, dashboards) and establish actionable SLOs/SLIs. • Plan and execute performance testing and scalability validation; partner with engineering to remediate bottlenecks and improve system performance. • Collaborate with engineering, architecture, security, and client stakeholders to triage issues, estimate work, and continuously improve delivery and reliability.

• 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.
