You will remain actively involved in architecture, automation, implementation, troubleshooting, and operational support while mentoring engineers, setting technical standards, and coordinating the team’s delivery. The ideal candidate has deep, practical expertise in Amazon Web Services (AWS) and working knowledge of other major cloud platforms, particularly Microsoft Azure and GCP.
Key Responsibilities
Hands-on Engineering (60%)
- Design and implement secure, scalable, resilient, and highly available cloud and hybrid environments, primarily on AWS.

- Build and maintain automated CI/CD pipelines using GitLab CI, Argo CD, Jenkins, GitHub Actions, or similar tools.
- Implement GitOps practices and automate application deployment, configuration, testing, and release processes.
- Provision and manage infrastructure using Terraform and/or AWS CloudFormation, following reusable and version-controlled Infrastructure as Code practices.
- Design, deploy, and operate containerized workloads using Docker and Kubernetes, preferably Amazon EKS.
- Improve Kubernetes resilience through effective workload configuration, autoscaling, resource management, health checks, ingress, secrets management, and disaster-recovery practices.
- Develop automation and operational tooling using Python, Bash, or PowerShell.
- Implement comprehensive observability using Prometheus, Grafana, OpenTelemetry, centralized logging, distributed tracing, alerting, and service-level indicators.
- Embed security throughout the software delivery lifecycle, including identity and access management, secrets management, vulnerability scanning, policy enforcement, encryption, and supply-chain security.
- Troubleshoot complex infrastructure, deployment, performance, and production reliability issues.
- Participate in incident response, root-cause analysis, capacity planning, and continuous service improvement.
- Identify opportunities to improve reliability, security, developer productivity, performance, and cloud cost efficiency.
Leadership and Management (40%)
- Lead, mentor, and develop DevOps, cloud, and platform engineers through coaching, technical guidance, and regular feedback.
- Establish and maintain engineering standards for cloud architecture, automation, CI/CD, security, reliability, and operational readiness.

- Provide technical direction while balancing delivery timelines, operational risk, scalability, security, and cost.
- Review architectural proposals, infrastructure code, automation, and operational processes.
- Promote a culture of ownership, collaboration, documentation, continuous improvement, and blameless learning.
- Coordinate incident response and ensure corrective actions are documented, prioritised, and completed.
- Support recruitment, onboarding, performance management, career development, and capability planning.
- Communicate technical risks, dependencies, progress, and recommendations clearly to technical and non-technical stakeholders.
- Champion DevSecOps, Site Reliability Engineering, and cloud governance practices across the organisation.
