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, Git Ops 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 · Git Ops · Argo CD · Terraform · Crossplane · KMS · Secrets Management · IAM · TLS · Prometheus · Grafana · Open Telemetry 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. xqbhyrx 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.
