Job description

Location: Tanjong Pagar
Working Hours: Office Hours
Salary: up $5,800 monthly basic

Monitoring, Observability & Service Assurance

• Manage and operate centralized monitoring dashboards and observability platforms across applications, databases, infrastructure (compute and storage), and network environments (on-premises and cloud) supporting 24/7 services.

• Continuously track system health using metrics, logs, and alerts to proactively identify anomalies, performance degradation, and potential issues.

Alerting, Triage & Coordination

• Respond to alerts and anomalies by conducting initial triage, impact assessment, and cross-system event correlation.

• Coordinate and elevate issues to the appropriate teams (Application, Cloud/Infrastructure, Network, Database) to ensure timely resolution in line with SLAs.

Monitoring Strategy, Design & Governance

• Define and implement monitoring strategies, including frameworks, alert thresholds, escalation policies, and observability standards.

• Collaborate with engineering teams to onboard systems into monitoring platforms and establish meaningful metrics and alerts.

• Continuously review and refine monitoring frameworks to reduce noise and improve the signal-to-noise ratio.

Service Health & Reporting

• Develop and maintain real-time service health dashboards for operational monitoring and reporting.

• Track and analyze system, network, and cloud availability, performance trends, and recurring incident patterns.

• Support reporting needs for service management, senior leadership, and key stakeholders.

Incident Support & Service Reliability

• Support major incident management by providing system visibility, diagnostics, and cross-team coordination.

• Identify recurring issues and reliability gaps, driving improvements in system stability, monitoring coverage, and response times.

FinOps, Cost Monitoring & Governance

• Monitor and manage cloud and infrastructure costs, including AWS usage (compute, storage, data transfer), as well as network and connectivity expenses.

• Implement cost allocation, tagging strategies, and budget monitoring with alerting mechanisms.

• Analyze cost drivers and identify optimization opportunities.

Cost Reporting & Optimisation

• Prepare and present cost reports, dashboards, forecasts, and trend analyses.

• Partner with engineering teams to optimize resource utilization, recommending rightsizing and cost-saving initiatives.

• Ensure a balanced approach between cost efficiency, performance, and reliability.

Cross-Team Coordination

• Serve as the central coordination point across Application, Cloud/Infrastructure, Network, and Database teams to align monitoring insights with operational actions.

Continuous Improvement & SRE Evolution

• Drive initiatives to enhance observability, expand monitoring coverage, and automate alerting and response workflows.

• Contribute to the adoption of Site Reliability Engineering (SRE) practices, including SLIs, SLOs, and error budgets.

Documentation

• Maintain documentation for monitoring architecture and dashboards, alerting rules and escalation procedures, cost governance models, and reports.

Operational Support

• Participate in major incident response and critical service monitoring.

• Provide after-hours support, including weekends and public holidays, as required.

Requirements:

• Training in Computer Science, Information Technology, Engineering, or a related field.

• 3 to 5 years of experience in IT operations, system monitoring, NOC, service assurance, or cloud/infrastructure operations.

• Hands-on experience with monitoring and observability platforms.

• Experience working in hybrid environments (on-premises and AWS cloud).

• Strong understanding of system and network monitoring concepts, as well as application and infrastructure health metrics.

• Proficiency with tools such as CloudWatch, Grafana, Prometheus, Splunk, ELK Stack, or similar platforms.

• Ability to analyze and interpret logs, metrics, and alerts effectively.

• Experience with AWS Cost Explorer, budgeting, and tagging strategies, with a good understanding of cloud cost structures and optimization techniques.

• Familiarity with ITIL processes (Incident, Problem, and Change Management), service level management, and observability practices.

• AWS certifications (Associate level or above) or AWS FinOps Certified Practitioner are preferred.

• Familiarity with ITIL processes (Incident, Problem, Change Management), Service Level Management and Observability principles

• AWS Certification (Associate level or above) or AWS FinOps Certified Practitioner preferred
