Application Support Engineer — L3

Responsibilities

- Own incident resolution across priority levels, RCA, and problem management
- Advanced diagnostics across MySQL, PostgreSQL, SQL Server, app logs, queues and integration interfaces
- Author new SQL and PowerShell scripts; mid-level .NET log and code investigation
- Patching, backup, and DR operations execution and validation
- Coach L2 engineers; maintain runbooks, KEDB and knowledge articles
- Hold SME ownership in one domain: Reporting / Clearing / Chargeback / Patching / Host interface / Message processing
- Represent support in change reviews and post-incident reviews; drive preventative actions to closure
- Shift-based coverage aligned to the agreed support roster, including on-call rotation

Reliability & SRE Practices
- Define and maintain SLIs/SLOs for the owned domain; track error budget burn and escalate reliability risk
- Build automation that removes toil — auto-remediation, diagnostic tooling and scripted runbooks
- Own observability for the domain: dashboards, structured logging standards, distributed tracing, and ing on golden signals
- Lead blameless post-incident reviews; manage MTTR and incident recurrence as tracked metrics
- Monitor capacity and performance — throughput headroom, queue depth, database growth — and warn before saturation
- Plan and execute resilience testing: DR failover drills, backup restore validation and controlled game days




- Apply production readiness criteria to current releases (monitoring, runbook, rollback path) and use IaC/CI-CD to make operational changes repeatable and auditable

- PCI DSS and FCA operational resilience — working knowledge
- ITIL-aligned incident, problem, and change management
- SRE practice — SLI/SLO definition, error budget tracking, toil reduction, blameless postmortems
- Infrastructure-as-code (Terraform / CloudFormation) and CI/CD pipelines for automated, auditable remediation
