Team Member, Devops Engineer

Duties and Responsibilities

1. CI/CD Pipeline Development & Maintenance

• Build, configure, and maintain CI/CD pipelines (Azure DevOps) for banking applications — internet banking, mobile banking APIs, USSD gateways, and core banking integrations.
• Implement multi-stage pipeline workflows: code compilation, unit testing, integration testing, SAST, DAST, container image scanning, and deployment to dev, UAT, staging, and production environments.
• Maintain and improve pipeline-as-code definitions stored in version control; apply peer-review discipline to all pipeline changes.
• Troubleshoot and resolve CI/CD pipeline failures promptly; communicate impact to development squads and escalate systemic issues to the Team Lead.
• Support the implementation of GitOps practices for declarative, auditable Kubernetes deployments.
• Document all pipeline configurations, deployment procedures, and runbooks in the team’s knowledge base.

2. Container & Kubernetes Administration

• Build, tag, and optimise Docker container images for banking application workloads; enforce image-layering best practices to minimise attack surface and image size.
• Deploy and manage workloads on Kubernetes clusters ( AKS ) — write and maintain Helm charts, Kubernetes manifests (Deployments, Services, ConfigMaps, Secrets, Ingress).
• Monitor pod health, resource utilisation (CPU/memory limits and requests), and horizontal pod autoscaler (HPA) behaviour; resolve OOMKill events and CrashLoopBackOff failures.
• Administer container image registry (ACR); perform routine vulnerability scans on images and remediate critical findings.
• Support the Team Lead in enforcing Kubernetes RBAC, network policies, and pod security standards across namespaces.

3. Infrastructure as Code & Cloud Operations

• Write and maintain Terraform or Ansible code to provision and manage cloud infrastructure (VPCs, subnets, security groups, VMs, load balancers) in a repeatable, version-controlled manner.
• Follow IaC peer-review and approval workflows; ensure all infrastructure changes are tracked in Git and applied through approved pipelines — no manual console changes.
• Support cloud cost management: tag all resources correctly, identify idle or over-provisioned resources, and report savings opportunities to the Team Lead.
• Assist in managing cloud IAM roles, service accounts, and least-privilege policies across Azure environment.
• Participate in cloud environment housekeeping: decommissioning stale resources, rotating access keys, and verifying backup configurations.

4. Observability & Incident Response

• Configure and maintain monitoring dashboards and alerting rules for application services, pipelines, and cloud infrastructure.
• Respond to platform and pipeline alerts within defined SLAs; perform initial root-cause analysis and escalate to the Team Lead or relevant infrastructure team as appropriate.
• Participate in the DevOps on-call rotation; provide timely first-response for P1/P2 CI/CD and platform incidents affecting digital banking services.
• Contribute to post-incident reviews (PIRs): document findings, identify contributing factors, and implement assigned remediation actions.
• Track and report key pipeline and platform health metrics (build success rate, deployment frequency, MTTR) to the Team Lead weekly.

5. DevSecOps & Compliance

• Integrate and maintain security scanning tools within CI/CD pipelines — SAST, DAST (OWASP ZAP), dependency scanning (OWASP Dependency-Check), and secrets detection.
• Ensure pipeline security gates are enforced: no release promotes to production if critical SAST, DAST, or image-scanning findings remain unresolved.
• Manage secrets and credentials using approved vaults (Azure Key Vault); eliminate hardcoded credentials from codebases and pipeline configurations.
• Support the Bank’s compliance with CBN Cybersecurity Framework, PCI-DSS Requirement 6 (secure development), ISO 27001 Annex A.14, and the NDPA 2023 data-handling requirements in pipeline and deployment processes.
• Prepare DevOps toolchain and pipeline evidence for internal audits, CBN IT examinations, and PCI-DSS QSA reviews as directed by the Team Lead.

6. Automation & Continuous Improvement

• Write Python, Bash, or PowerShell scripts to automate repetitive DevOps tasks — environment provisioning, log collection, health checks, certificate rotation, and deployment notifications.
• Identify manual steps in the software delivery process and propose automation solutions to the Team Lead; implement approved improvements.
• Contribute to the Bank’s internal developer platform (IDP): maintain golden-path pipeline templates, Terraform modules, and Helm chart libraries for use by development squads.
• Stay current with CI/CD, container, cloud, and DevSecOps developments; share relevant learnings and tool evaluations with the DevOps team.
• Support onboarding of new development squads onto the CI/CD platform: provide documentation, walkthroughs, and first-line pipeline support.

Required Skills & Qualifications

• Bachelor’s degree in computer science, Software Engineering, Information Technology, or a related discipline from an accredited institution.
• 3–5 years of hands-on  DevOps of software infrastructure experience, CI/CD pipeline development, container management, IaC or Cloud operations preferably in banking, fintech, or comparably regulated environment. Experience supporting deployments for core banking or digital channel applications is an added advantage.
