Job description

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.

Responsibilities

• 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.

Technology environment

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.

What we’re looking for

• 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.

Working pattern

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

Package

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