Cloud Architecture and DevOps Lead - Telco Private Cloud

Cloud Architecture and DevOps Lead – Telco Private Cloud

Position Description
We are seeking an experienced Cloud Architecture and DevOps Lead to design and deliver a telecom grade private cloud platform. The role will lead the migration from VMware based infrastructure to a Kubernetes based private cloud and support the onboarding of containerized network functions, 5G Standalone Core, Ericsson ADI, and Rakuten Open RAN workloads.

The successful candidate will work across cloud architecture, Kubernetes, DevOps, networking, security, automation, and telecom platforms to establish a scalable, secure, and operationally efficient environment.

Your future duties and responsibilities
Key Responsibilities
Private Cloud and Kubernetes Architecture

. Define the target architecture for migrating VMware workloads to a Kubernetes based private cloud.
. Develop migration strategies for virtual machines, applications, and network functions.
. Design highly available Kubernetes clusters across data centres and edge locations.
. Define standards for compute, storage, networking, observability, backup, disaster recovery, and lifecycle management.
. Establish cloud native patterns for VM, container, and CNF workloads.
. Support virtualization technologies such as KubeVirt where VM workloads must continue to run on Kubernetes.

Containerization and CNF Modernization

. Lead the containerization and modernization of legacy applications and telecom network functions.
. Support onboarding, deployment, scaling, upgrades, and lifecycle management of containerized network functions.
. Define Helm, GitOps, CI/CD, image management, and configuration standards.
. Implement automated testing, release management, rollback, and version control.
. Ensure workloads meet telecom grade requirements for performance, resiliency, latency, and availability.

DevOps and Automation

. Establish DevOps and GitOps practices across infrastructure, platform, and network function delivery.
. Build automated pipelines for infrastructure provisioning, application deployment, configuration, testing, and operational changes.
. Implement Infrastructure as Code using tools such as Terraform, Ansible, and related automation frameworks.
. Integrate source control, CI/CD, security scanning, artifact repositories, and change management.
. Improve deployment frequency, operational consistency, and time to recover from failures.

Security Architecture

. Embed security into the private cloud and DevOps lifecycle.
. Define identity, access control, secrets management, certificate management, and privileged access controls.
. Implement container, image, Kubernetes, API, and supply chain security.
. Support zero trust principles, network segmentation, micro segmentation, and workload isolation.
. Establish security monitoring, vulnerability management, audit logging, compliance controls, and incident response integration.
. Collaborate with enterprise security teams to meet telecom and regulatory requirements.

Network Architecture and Integration

. Design Kubernetes networking for telecom workloads, including CNI, multus networking, service meshes, ingress, load balancing, and IP management.
. Support integration with data centre, transport, firewall, DNS, IPAM, SDN, and service assurance platforms.
. Define network performance requirements for low latency, high throughput, resiliency, and deterministic behavior.
. Support connectivity between private cloud, enterprise networks, edge locations, and telecom infrastructure.
. Develop network automation for provisioning, configuration, validation, and operational support.

Telecom Platform Onboarding

. Lead the onboarding of Ericsson ADI stack components into the private cloud environment.
. Support the deployment and integration of 5G Standalone Core network functions, including AMF, SMF, UPF, UDM, AUSF, PCF, NRF, and related services.
. Support onboarding of Rakuten Open RAN components and associated RAN, cloud, transport, and orchestration platforms.
. Validate interoperability across RAN, transport, 5G Core, OSS/BSS, inventory, orchestration, and assurance systems.
. Ensure platform designs support telecom standards, CNF lifecycle management, observability, and operational handover.

Observability and Operations

. Define observability standards for infrastructure, Kubernetes, applications, CNFs, and network services.
. Implement centralized monitoring, logging, tracing, event management, and dashboarding.
. Support integration with tools such as Prometheus, Grafana, Elastic/Kibana, Splunk, Dynatrace, or equivalent platforms.
. Establish service level indicators, service level objectives, capacity monitoring, and operational health checks.
. Enable automated fault detection, remediation, and closed loop operational processes.
