Senior Platform Engineer

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.
