Senior Golang Engineer – Kubernetes Controllers & Secrets Management About the Role We are looking for a

Senior Golang Engineer

to join a cloud platform engineering team building highly automated, secure and scalable cloud-native infrastructure. This role sits at the intersection of

Kubernetes engineering, platform automation and cloud security . You will work hands-on developing

Kubernetes Controllers and Operators in Go , automating the lifecycle of platform services and cloud resources, while contributing to secure

Secrets Management and Key Management (KMS)

capabilities used across the platform. This is not simply a role operating Kubernetes. We are looking for engineers interested in

building and extending Kubernetes itself through APIs, Controllers, Operators and automation . What You'll Be Doing Kubernetes Controllers & Platform Engineering Design, develop and maintain

Kubernetes Controllers and Operators using Go/Golang . Build automation around Kubernetes resources using

CRDs and Kubernetes APIs . Automate the provisioning, configuration and lifecycle management of cloud and platform resources. Build reliable reconciliation and control-loop logic for distributed systems. Contribute to

multi-cluster Kubernetes environments

and platform orchestration. Develop internal platform capabilities that enable engineering teams to consume infrastructure and services through automated, self-service workflows. Improve CI/CD, GitOps and Infrastructure-as-Code processes. Troubleshoot complex Kubernetes and distributed-system issues in production environments. Help ensure the reliability, scalability and observability of platform services. Secrets Management,



KMS & Security Design and develop services for secure

Secrets and Key Management

within Kubernetes and cloud environments. Integrate secrets-management capabilities with Kubernetes workloads and platform services. Work with

KMS, IAM, TLS/certificates and secure service-to-service communication . Implement secure key lifecycle processes including generation, storage, access and

key rotation . Contribute to platform and Kubernetes cluster hardening. Apply security best practices across highly automated and distributed environments. Work with cryptographic concepts such as

envelope encryption, DEK/KEK and encryption at rest/in transit . What We're Looking For Core Requirements Strong professional experience developing software with

Go / Golang . Strong hands-on experience with

Kubernetes

in production environments. Experience developing

Kubernetes Controllers, Operators or Kubernetes-native automation . Good understanding of Kubernetes APIs and

Custom Resource Definitions (CRDs) . Experience designing or working with

distributed systems and cloud-native architectures . Strong understanding of software engineering principles and API design. Experience with CI/CD, automation and Infrastructure as Code. Comfortable troubleshooting complex Kubernetes and platform-level problems.



Security & Secrets Experience Experience in some of the following areas would be highly valuable: Secrets Management Key Management Systems / KMS IAM TLS and certificate management Kubernetes security and cluster hardening Key rotation Encryption and applied cryptography Secure communication between distributed services Technologies You May Work With Go / Golang · Kubernetes · Kubernetes API · CRDs · Controllers · Operators · Kubebuilder · controller-runtime · Cluster API · GitOps · ArgoCD · Terraform · Crossplane · KMS · Secrets Management · IAM · TLS · Prometheus · Grafana · OpenTelemetry Exposure to cryptographic concepts such as

AES, RSA, ECDSA, HMAC, envelope encryption and DEK/KEK

is a strong plus. Nice to Have Experience with

Kubebuilder or controller-runtime . Experience with

Cluster API (CAPI)

or Crossplane. Experience building Kubernetes platforms across

multiple clusters . Experience with secure, segmented or

air-gapped environments . Experience building internal developer platforms or self-service infrastructure. Knowledge of multi-tenancy and policy-as-code. Experience with OPA/Rego. Strong understanding of applied cryptography and key-management architectures. The Profile We're Looking For You don't need to tick every box. We're particularly interested in engineers who have a strong

Go + Kubernetes engineering background

and enjoy building the automation and software that sits behind a cloud platform. If you have built

Kubernetes Controllers, Operators, CRDs or Kubernetes-native platform services , and you are interested in going deeper into

Secrets Management, KMS and cloud security , this could be a great fit.
