- Développeur / Développeuse senior, plateformes infonuagiques
About YouYou are a senior cloud platform developer with deep expertise in Infrastructure as Code and multi-cloud environments, and you're energized by building self-service tools that other engineering teams genuinely want to use. You think of platforms as products-you track how developers experience your work, respond to usage signals, and iterate accordingly. You're equally comfortable writing production-ready Terraform modules and engaging with a development team to help them adopt them. You bring hands-on experience hardening distributed systems and embedding security and cost guardrails directly into provisioning pipelines. You are curious about how AI-assisted tooling-such as MCP-connected agents or IDE assistants-can reduce cognitive load and accelerate delivery, and you're ready to build those capabilities, not just consume them. You have strong communication skills and you work well within a globally distributed team, and you mentor peers by sharing debugging techniques and platform best practices in ways that scale your impact.
What you'll do and how you'll have an impact- Configure and extend multi-cloud, multi-region, multi-tenant infrastructure using Terraform Cloud and Ansible automation pipelines.
- Design and maintain reusable IaC modules, and work directly with engineering teams to drive their adoption across the organization.
- Build AI-assisted, guardrailed self-service workflows-including MCP servers and policy/cost validation-that make the secure path the default path.
- Embed FinOps and security guardrails (ISO 27001, SOC 2, PCI) into the provisioning layer so compliance is validated at design time, not after deployment.
- Support the onboarding of newly acquired teams onto the Cloud Platform so they can ship confidently from day one.
- Use observability tools such as Datadog to diagnose issues in complex distributed systems and lead incident response when needed.
- Participate in our DevOps Guild, training DevOps Champions on platform capabilities and maintaining documentation for both human users and AI agents.
- Provide on-call support on rotation to maintain cloud infrastructure health.
- Mentor junior engineers and share knowledge, including debugging techniques and platform best practices.
- Administer and optimize Cloudflare services and DNS architecture across providers (Route53, Cloudflare, GoDaddy), supporting domain and edge-related migration projects with minimal downtime and robust rollback planning.
What we're looking for- 6+ years of professional experience in cloud infrastructure or platform development roles.
- Expertise in Infrastructure as Code with Terraform and Ansible (or comparable tools such as Chef, Puppet, or Salt), including writing complex automation and enabling others to adopt it.
- Hands-on experience deploying and managing applications on AWS or Azure or GCP, with an understanding of performance optimization and cost management.
- Demonstrated ability to independently secure and harden cloud infrastructure in compliance-driven environments.
- Solid foundation in networking, operating systems, databases, and service configuration in a microservices context.
- Experience with CI/CD pipelines and source code management workflows (e.g., GitHub Actions, ArgoCD).
- Comprehensive experience managing DNS, domain lifecycles, and traffic routing across providers like Cloudflare (DNS, proxying, SSL/TLS, WAF, edge services), AWS Route53, or GoDaddy.
- Strong written communication skills in English, because you'll coordinate technical decisions across globally distributed teams and present platform strategy to senior stakeholders.
- A continuous improvement mindset, because this role requires you to treat usage metrics and support requests as feedback signals and act on them to make the platform measurably better over time.
- Understanding of containerization platforms like Docker and container orchestration platforms like Kubernetes is nice to have.
- Strong experience with Continuous Integration/Delivery pipelines and corresponding tools (e.g., ArgoCD, Jenkins, GitHub Actions) is nice to have.
- Experience in writing and testing code in at least one programming language (Java, JavaScript, Golang) is nice to have.
- Comprehensive knowledge and debugging abilities for complex applications in Java, Node.js, or Golang, and ability to train others in debugging techniques is nice to have.
- Experience building AI-native platform capabilities-Model Context Protocol (MCP) servers, or AI-assisted incident response and runbooks is nice to have.
- Knowledge or hands-on experience with Google Cloud Platform (GCP) is nice to have.
- Familiarity with FinOps practices and policy-as-code for cost and compliance guardrails is nice to have.
