iO Associates is working with a growing technology consultancy supporting complex, business-critical application and integration platforms across regulated environments, including healthcare. They are looking to hire an Application Support Analyst to join their expanding support and operations team.
This role is well suited to someone with a solid L1/L2 support background who has begun supporting applications, interfaces, or middleware and is keen to continue developing their skills within integration and enterprise systems.
The role:
You'll be responsible for supporting the availability, performance, and reliability of client-facing applications and integration platforms, alongside providing internal IT and application support. You'll work closely with senior support analysts, engineers, and infrastructure teams, gaining hands-on exposure to healthcare integration environments and enterprise middleware.
Key responsibilities include:

• Providing L1/L2 application and integration support across client platforms
• Monitoring, triaging, and resolving incidents in line with SLAs and ITIL processes
• Investigating application, interface, and message-flow issues
• Supporting integration engines and middleware platforms (training provided where required)
• Performing basic root cause analysis and escalating appropriately
• Supporting internal systems, user access, and day-to-day IT/application issues
• Maintaining clear documentation, runbooks, and knowledge articles
• Communicating clearly with clients and internal stakeholders
• Participating in an out-of-hours support rota (fully supported and structured)

What they're looking for:

• 2-5+ years' experience in IT support, service desk, or application support
• Strong troubleshooting skills with a methodical, analytical approach
• Experience supporting applications or business-critical systems
• Exposure to integration, interfaces, or middleware (commercial or support-based)
• Familiarity with Microsoft 365 administration, including Entra ID
• Understanding of networking fundamentals (TCP/IP, DNS, VPNs, proxies)
• Working knowledge of Windows and/or Linux environments
• Experience using ITSM tools (e.g. Jira, ServiceNow, Freshservice, Confluence)
• Confident communication skills and a customer-focused mindset
• Any exposure to healthcare or NHS environments and integration engines such as InterSystems, Rhapsody, or Mirth is highly desirable

Why apply?

• Clear progression into application, integration, and middleware support
• Structured training and mentoring
• Exposure to complex, real-world healthcare systems
• Supportive, collaborative team environment
• Flexible remote-first working

If you're an IT or application support professional who's started moving into middleware or integration support and wants to continue that journey in a structured, supportive environment, this is a strong next step.
