Site Reliability Engineer (SRE) (GovTech)

We are seeking a skilled and passionate Engineer to join our team to build and operate a Whole-of-Government (WoG) runtime platform.

As a Site Reliability Engineer, you will be responsible for designing and operating GitLab, AWS and Kubernetes-based infrastructure and solutions that power our platform, to ensure the stability, scalability, and performance of our runtime platform.

Responsibilities:

As a Site Reliability Engineer, you will be responsible for:

Toil Reduction & Automation

• Identify repetitive tasks and develop automation via CI/CD pipelines, ensuring integration with cross-functional teams to reduce manual intervention and improve operational efficiency.

Observability & System Health

• Implement comprehensive observability solutions (logs, metrics, traces, alerts) around the four Golden Signals (latency, traffic, errors, saturation), and build automation for proactive system health assessments and self-remediation.

Production Support & Incident Management

• Participate in on-call rotations, promptly respond to incidents to minimize MTTR, and conduct thorough post-incident reviews to implement preventive measures and improve system resilience.

Security & Compliance

• Design and implement solutions that are secure and compliant by collaborating with dedicated security teams, conducting regular audits, and integrating advanced vulnerability scanning tools.

Maintenance, Optimisation & Performance

• Identify and resolve performance bottlenecks and operational issues, define and track KPIs (e.g., MTTR, system uptime, cost efficiency), and drive ongoing optimisation efforts.

Strategic Customer Engagement

• Act as a technical advisor for tenants, guiding them on containerization, and best practices for cloud-native deployments, and participating in strategic initiatives to enhance platform scalability and performance.

Knowledge Sharing & Documentation

• Develop and maintain detailed playbooks, runbooks, and documentation to facilitate team-wide knowledge sharing, streamline incident response, and ensure that critical processes are well understood across the team.

Continuous Learning & Innovation

• Stay current with the latest AWS, Kubernetes, and industry developments, and proactively recommend improvements and innovative solutions to maintain a competitive and reliable platform.

Requirements:

• Bachelor's degree or Diploma in Computer Science, Engineering, or a related field (or equivalent experience).
• Proven experience as a Site Reliability Engineer or similar role, with a strong background in containerization, orchestration, and cloud-native technologies.
• Proven ability to troubleshoot and resolve complex technical issues in containerized applications.
• Demonstrated experience with incident management, including post-incident reviews and continuous improvement.
• Strong documentation skills and experience in knowledge sharing across teams.
• Deep understanding of AWS, Kubernetes (including AWS EKS), and operational best practices, with familiarity in multi-cloud or hybrid environments.
• Solid grasp of networking, security, and storage in both AWS and Kubernetes contexts.
• Experience integrating Kubernetes with AWS cloud technologies (e.g., Secrets Manager, Load Balancers) and using infrastructure-as-code (Terraform or similar).
• Hands-on experience with containerization tools (Kubernetes, Kustomize, Helm) and automation scripting (Go, Python, Bash, or equivalent).
• Ability to write and maintain automated tests or conduct thorough manual testing for automation scripts, ensuring the reliability and effectiveness of automated solutions.
• Familiarity with CI/CD tools (GitLab CI/CD, ArgoCD) and version control systems (Git).
• Experience with observability/monitoring tools (Prometheus, Grafana, ELK Stack) and defining SLOs and Error Budgets.
• Certifications such as Certified Kubernetes Administrator (CKA) or Certified Kubernetes Application Developer (CKAD) are a plus.
• Experience with developing Kubernetes operators using Go, service mesh technologies, and Chaos Engineering is a plus.

Soft skills:

• Proactive in identifying problems and recommending strategic solutions.
• Excellent problem-solving skills with a robust analytical mindset.
• Clear, concise, and effective communication skills; adept at collaborating across crossfunctional teams, including development, security, and customer-facing groups.
• Ability to remain calm and effective under pressure, especially during incident response.
• Adaptability to rapid change with a continuous learning mindset, sharing knowledge to foster team growth.
• Customer-focused with the ability to translate technical insights into understandable, actionable guidance.
• Leadership and mentoring capabilities, contributing to the development of a resilient and collaborative team environment are a plus.
