Job description

Application Support Analyst – ERP & Integrations

TechHeads are looking for an experienced Application Support Analyst to join a growing IT team in a hands‑on role supporting business‑critical applications, ERP systems and integrations.

This is a particularly good opportunity for someone who enjoys the technical side of application support and wants a role where they can investigate problems properly rather than simply logging tickets and escalating them. You’ll have the opportunity to get behind the user interface, follow transactions across different systems and use SQL, APIs, logs and monitoring tools to understand what has actually gone wrong.

The role offers plenty of technical variety. One issue could involve investigating an ERP or data problem, while the next could mean tracing a failed API transaction, troubleshooting an integration or identifying the cause of a performance issue within a live application.

You’ll also have the opportunity to build broader expertise across enterprise applications, ERP, databases, APIs and integrations, while working closely with developers, technical specialists and third‑party vendors. You won’t be expected to simply pass complex problems to another team — you’ll have the ownership and tools to investigate them, identify the likely root cause and play a meaningful part in getting them resolved.

It would suit an Application Support Analyst who is naturally curious about how systems work together, enjoys problem‑solving and wants to continue developing towards deeper technical application, integration and ERP expertise.

Key Responsibilities:

• Provide technical support across ERP systems, business applications and B2B integrations.
• Investigate and resolve application, transactional and performance issues within live production environments.
• Troubleshoot REST/SOAP APIs, web services, automated integrations and scheduled data feeds.
• Use SQL to investigate application issues, reconcile data, validate transactions and identify data discrepancies.
• Test and troubleshoot APIs using Postman or similar tools, analysing payloads, authentication, responses and integration failures.
• Trace transactions across applications, APIs, integrations, databases and ERP systems to identify the source of technical issues.
• Investigate master‑data and configuration issues and support the resolution of data‑related application problems.
• Manage incidents, service requests and changes through an ITSM platform in line with agreed SLAs and change‑management processes.
• Work closely with developers, business analysts, internal IT teams and third‑party technology vendors to resolve complex issues.
• Produce Root Cause Analysis, technical documentation, SOPs and knowledge‑base documentation.

Requirements:

• 4+ years' IT experience, including at least 2 years within Application Support, ERP Support, Systems Analysis or a similar technical role.
• Previous experience supporting an ERP system.
• Strong practical SQL querying skills, including joins, filtering, aggregation and subqueries.
• Experience troubleshooting REST and/or SOAP APIs using Postman or similar tools.
• Good understanding of application architecture, integrations and end‑to‑end data flows.
• Experience troubleshooting issues within live production environments.
• Experience working with JSON, XML, CSV/flat files and web services/integrations.
• Ability to investigate technical issues beyond the application UI using SQL, logs, APIs and monitoring tools.
• Familiarity with ITIL processes, including Incident, Problem, Service Request and Change Management.

Rest assured that every application is carefully reviewed by our recruitment team, and a shortlist of candidates whose skills and experience closely match the role requirements will be contacted.
