Responsibilities

As a Senior Engineer, IT Infrastructure, you will take on a hybrid role spanning Network, Systems, and FinOps engineering. In this position, you will be responsible for end-to-end monitoring, observability, and service assurance, ensuring reliable and high-performing systems across applications, databases, infrastructure, and network services. You will oversee alert management, incident triage, and support, while maintaining clear visibility of service health through reporting. Additionally, you will drive cost governance initiatives and collaborate across teams to ensure operational efficiency and alignment.

Key Tasks you will be involved in:

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 escalate 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 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, critical service monitoring, and provide after-hours support (including weekends and public holidays) as required.
