Senior Platform Engineer

Over deze vacature

At Sytac, we build high-performing engineering teams for leading organizations. We combine a pragmatic, people-first culture with technical craftsmanship, giving engineers autonomy in real production environments. For one of our key clients in the Netherlands, we are looking for a Senior Platform Engineer who lives and breathes cloud-native infrastructure. This isn't a role for someone who has "worked with Kubernetes" — it's for someone who has architected it, scaled it, and owned it across complex production environments. You'll be building and evolving a platform that engineering teams depend on every day, with GitOps and Internal Developer Platform thinking at its core. What you'll do • Design, build, and maintain cloud-native platform infrastructure with Kubernetes as a first-class citizen — architecture-level ownership, not just operations. • Own and evolve Infrastructure as Code at senior level using Terraform — setting standards, not just implementing them. • Build and scale CI/CD pipelines that serve multiple teams and workloads at scale, ensuring fast, reliable, and secure delivery. • Implement and maintain GitOps workflows using ArgoCD — driving deployment consistency and auditability across environments. • Collaborate with engineering teams to improve developer experience and platform reliability. • Contribute to and potentially help build an Internal Developer Platform (IDP) that enables teams to self-serve infrastructure and deployment capabilities. What we're looking for • Senior-level Terraform and Infrastructure as Code experience across cloud providers — you set the standard, not just follow it. • Extensive Kubernetes experience — GKE, EKS, AKS or equivalent — at an architectural level. This goes well beyond having worked with it. • Proven CI/CD experience at scale — multiple teams, multiple pipelines, complex workloads. • Hands-on ArgoCD experience in a production environment. • Solid GitOps experience — ArgoCD, Flux, or both — across more than one employer or context. • A platform mindset: you build for others, optimise for usability, and care about developer experience as much as infrastructure correctness. • Java experience is not required for this role. Nice to have • Experience building or contributing to an Internal Developer Platform (IDP). • CKAD or CKA certification — or equivalent demonstrable depth in Kubernetes. • Experience with landing zones, cloud governance, and IaC standards at an enterprise scale.
