Job summary

Senior Platform Engineer at Sytac leads the design and evolution of a cloud-native platform used by multiple engineering teams in the Netherlands. You will architect Kubernetes-based infrastructure, own IaC standards with Terraform, and drive scalable CI/CD pipelines with GitOps workflows such as ArgoCD.

You will collaborate with developers to improve platform usability and reliability, and help shape an Internal Developer Platform to empower teams to self-serve infrastructure and deployments.

Qualifications

• 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.
• 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.

Responsibilities

• 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.

Job description

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.
