Senior Application Support Developer

Overview

Senior Application Support Developer
Location: West Yorkshire (Hybrid)
Salary: £65,000 + £6,000 car allowance + up to 10% bonus

We are recruiting a Senior Application Support Developer to join a technology team responsible for maintaining and supporting a large, business-critical application estate.

This is a true application support role. The focus is on resolving bugs, handling tickets, and delivering small, incremental fixes across multiple applications, rather than building new features or greenfield systems.

• Work in a Kanban-style environment, picking up tickets raised through 1st, 2nd and 3rd line support and taking them through investigation, fix and resolution.
• Debug and fix production issues, make small targeted code changes, support and maintain multiple applications.
• Investigate data and reporting issues, work across a mixed and legacy technology estate, and collaborate closely with support teams and other developers.
• Focus on keeping systems running reliably and improving them incrementally, not delivering large projects or redesigning platforms.

You will be working across a legacy-heavy but business-critical stack, including Classic ASP, JScript, C#, .NET, Java, SQL and relational databases, SSIS and SSRS.

You don’t need to be an expert in every technology listed, but you do need to be comfortable working in and around them.

• Strong experience as an Application Support Developer or in a support-led development role, comfortable working on bugs, tickets and small fixes rather than large feature builds.
• Experience supporting live production systems, confidence debugging legacy code and mixed technology stacks.
• Strong SQL skills for investigation and fixes, and a calm, methodical approach to problem solving.

Hybrid working with 2 days per week onsite in West Yorkshire.

£65,000 base salary, £6,000 car allowance, plus up to 10% bonus.
