We build and operate the internal platform that enables our teams to ship reliable and secure services. As a platform engineer, you’ll take ownership of key platform components, drive automation, and improve reliability through strong operational practices. Join our team and defend the digital future with us! 

Your tasks

  • Design, implement, and evolve infrastructure provisioning and configuration using Terraform and Ansible and operate core platform components (virtualization, compute, foundational services) with a production-first mindset
  • Drive reliability improvements through monitoring, alerting, and capacity planning (alerts on symptoms, not just outages)
  • Plan and execute maintenance and upgrades (patching, hardening, change planning, rollback strategies) aligned with security and compliance requirements
  • Participate in incident response and on-call rotation; lead troubleshooting, coordinate escalation, and contribute to post-incident improvements
  • Collaborate across teams to deliver scalable platform capabilities (CI/CD foundations, availability, performance, developer experience)
  • Raise the bar on documentation: runbooks, operational guides, and decision records explaining the “why” (not only the “what”)

Your Skills

  • Solid hands-on experience in platform/infra/DevOps
  • Strong Linux administration skills and good networking fundamentals (TCP/IP, DNS, SSL/TLS, OSI, etc.)
  • Strong automation skills with Python or Go plus shell scripting; you write maintainable tools (logging, safe defaults, testing mindset)
  • Proven experience with Terraform and Ansible in production (idempotency, reusable modules/roles, reviewable changes, state discipline)
  • CI/CD experience with GitLab (pipelines, runners, artifacts, secrets handling) and Git-based workflows (merge requests, reviews, branching)
  • Operational excellence: you troubleshoot systematically, reduce toil with automation, and improve reliability over time
  • Comfortable working within an ISMS / regulated environment and applying security best practices by default
  • Fluency in French and good English (min. B2) skills are a must.
