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.
