Systems Engineering Experience : At least 4 years working with highly available, distributed, high-traffic systems such as game servers, media platforms, or global APIs, with strong uptime and performance requirements across staging and production. Design experience is a plus. Private Cloud exposure: Experience deploying and operating Private Cloud platforms, for example OpenStack, with responsibility for production stability and lifecycle management. Infrastructure-as-Code (IaC) : Proven use of Ansible and Terraform to provision and manage infrastructure at scale. CI/CD & GitOps : Proven use of Ansible and Terraform to provision infrastructure at scale, and solid experience building and maintaining GitHub Actions workflows, pipelines with GitOps tooling such as Argo CD. Observability experience : Hands-on experience with Prometheus and Grafana in production environments, ideally within multi-tenant or regulated contexts. Collaboration & Mentorship : Experience working in SRE, DevOps, or platform teams, mentoring engineers through code reviews and incident retrospectives, and contributing to internal tooling and documentation. Remote vs Onsite : This is a hybrid role, so you'll spend some time working onsite at our Rotterdam office. If you're already in the Netherlands, great. If not, we're happy to support your move with our relocation services (a valid EU work permit is required). Why join us?
