Job description

L2 Application Support Analyst – ERP Systems

TechHeads are working with an established Irish organisation looking to hire an experienced L2 Application Support Analyst to join its IT team, supporting business-critical applications, ERP systems and integrations.

This is a technical application support role within a busy enterprise environment, offering exposure to a broad range of applications, databases, APIs and integrated systems. The organisation is currently undertaking several significant technology projects, including a major ERP migration.

You’ll be responsible for investigating and resolving complex application issues, troubleshooting integrations, analysing data and identifying root causes across different systems. The role requires someone who enjoys getting behind the user interface to understand how applications work, how data flows between systems and where technical issues originate.

This is not a traditional IT Helpdesk or functional ERP support role. We're looking for someone with strong hands-on L2 application support experience who is comfortable investigating technical issues across applications, databases and integrations.

Key Responsibilities:

• Providing Level 2 technical application support across ERP systems, business-critical applications and integrated platforms.
• Investigating and resolving application incidents, identifying root causes across front-end, back-end, databases, APIs and integrations.
• Troubleshooting integration failures and tracing transactions and data flows between ERP platforms, internal applications and third-party systems.
• Using SQL and relational databases to investigate application issues, analyse data and identify or correct master-data problems.
• Analysing application logs, error messages and system traces to diagnose technical faults and identify where transactions or processes have failed.
• Investigating application performance issues, including timeouts, latency, database queries and transaction failures.
• Working closely with development and technical teams, providing detailed findings and technical information when escalating complex issues.
• Supporting application improvements, system changes and ongoing ERP-related projects.

Requirements:

• Proven experience in an L2 Application Support, Technical Application Support or similar role, with strong hands-on technical troubleshooting skills.
• Experience working with ERP systems such as Infor M3, SAP, Microsoft Dynamics, Sage or similar, with an understanding of ERP workflows and integrations.
• Good working knowledge of SQL and relational databases, including querying databases and investigating data-related issues.
• Understanding of APIs and system integrations, including the ability to investigate API requests, responses and integration failures.
• Experience troubleshooting technical application issues using logs, error messages and diagnostic tools to identify root causes.
• Good understanding of application architecture, including how front-end applications, back-end services, databases and third-party systems interact.
• Ability to trace transactions and data flows across multiple systems, identify points of failure and take a structured approach to troubleshooting.
• Strong analytical, problem-solving and communication skills, with the ability to work effectively with development teams and business stakeholders.
• Experience with Infor M3, API testing tools, scripting, automation, application monitoring/APM tools or ITIL environments would be advantageous.
