Job Description :

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 elevate 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 alerting 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 new releases (monitoring, runbook, rollback path) and use IaC/CI-CD to make operational changes repeatable and auditable

Technical Skills

• MySQL, PostgreSQL — deep hands-on; SQL Server — mid-level
• PowerShell and SQL — authoring new scripts independently
• .NET — mid-level (code and log-level diagnostics)
• AWS (ECS, EKS, RDS, CloudWatch); Coralogix, Grafana / Grafana Cloud, PagerDuty, Jira Service Management
• Distributed tracing and metrics instrumentation (OpenTelemetry) — able to instrument and interpret traces, not just build dashboards
• Payments domain — card issuing and processing, plus one of ISO 8583 / ISO 20022, clearing and settlement, or chargebacks and disputes
• 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

Good to Have:

• Kubernetes operations at scale
• Chaos engineering
• AI-assisted troubleshooting tooling in a controlled environment
• Confluence
• Payments/fintech background
