Main Responsibilities:

• Triaging, prioritising and resolving incidents, service requests and production signals across our application portfolio.
• Providing first- and second-line application support to colleagues across every department of the business, including face-to-face assistance where required.
• Operating our ITSM platform (JIRA Service Management) day-to-day queues, SLAs, request types and automations and contributing to its continual improvement.
• Creating, amending and removing user access and permissions across the applications we support.
• Investigating and root-causing complex, cross-system issues spanning our Azure services, databases, messaging layer, reporting platforms and third-party integrations.
• Monitoring production health and acting proactively on the signals it produces.
• Escalating defects to our IT Development team with high-quality, evidence-led reproduction steps and supporting material.
• Authoring and maintaining runbooks, knowledge base articles and known-error records in Confluence.
• Coordinating with other technical teams to support rollouts and system updates.
• Creating and executing reports and data analyses to support business decision making.
• Challenging current processes to enhance efficiency and remove waste.

• Analysing trends across incidents and alerts to reduce avoidable downtime.

Essential Skills & Experience:

• 3+ years of application support experience in a production SaaS or distributed-systems environment, covering both first-line access and permissions work and second-line application troubleshooting, with clear evidence of stretching into deeper investigative work.

• Strong working knowledge of Microsoft Azure, including Portal fluency, Application Insights / KQL, Log Analytics, Azure Functions, Storage and Key Vault.
• Practical experience of event-driven messaging platforms (Azure Service Bus or equivalent) producer/consumer patterns, dead-letter handling and message-based troubleshooting.
• Strong T-SQL skills including complex joins, execution plans, and reading and understanding stored procedures, as part of a broader investigative toolkit rather than the whole of the role.
• Read-level working knowledge of C#/.NET able to read a codebase well enough to understand application behaviour and raise precise defect tickets.
• ITIL discipline and confident day-to-day operation of an ITSM platform, with JIRA Service Management experience strongly preferred.
• Proficient troubleshooting and debugging skills underpinned by a proactive, evidence-led mindset.
• Excellent written and verbal English, with professional stakeholder communication at multiple levels of seniority.

Desirable Skills:

• Working knowledge of Elasticsearch, Kibana and the ELK stack, ideally including cluster administration.
• PowerShell scripting and/or Azure CLI / Az modules.
• Familiarity with Power BI troubleshooting gateway, refresh and dataset permissions and/or SSRS administration.
