We're working with a well-established public sector organisation looking for an experienced Senior Applications Developer to join its technology team.

This is an excellent opportunity for someone who enjoys working across a varied application landscape, combining hands-on development with application support, systems integration, legacy modernisation and continuous improvement.

You'll play a key role in maintaining and enhancing business-critical applications, improving existing systems and helping shape future technology solutions.

• Develop, maintain and enhance business-critical applications using C#, .NET and SQL Server.

• Support legacy applications, including upgrades, migrations and modernisation.

• Design and maintain APIs, system integrations and automated data processes.

• Investigate and resolve complex application issues, providing technical support and root-cause analysis.

• Take ownership of applications throughout their lifecycle, ensuring reliability, security and performance.

• Work closely with internal stakeholders, suppliers and technical teams to deliver improvements.

• Support releases, testing, documentation and knowledge transfer.

We're looking for someone with a strong background in application development and support, ideally including:

• C# / .NET / SQL Server development experience.

• Experience supporting and maintaining legacy or bespoke applications.

• Strong knowledge of APIs, integrations and relational databases.

• Experience with application troubleshooting, maintenance and enhancements.

• Understanding of Agile development, source control and release management.

• Excellent problem-solving, communication and stakeholder management skills.

• Ability to quickly understand unfamiliar applications and technologies.

Desirable experience:

• SSIS, SSAS or ETL processes.

• Power BI, Power Platform or SharePoint.

• Azure or other cloud technologies.

• ITIL or structured IT service management environments.

You don't need experience with every technology listed. We're particularly interested in developers who are adaptable, technically capable and comfortable working across a mixture of modern and legacy systems.

• Excellent flexibility, with full-time, part-time and remote working arrangements considered.

• Opportunity to work across a diverse range of applications and technologies.

• A varied role combining development, support, integrations and modernisation.

• Join a collaborative, small technical team where your expertise will make a genuine impact.

• Work on meaningful technology projects supporting essential public services.

If you're an experienced C#/.NET Developer with a background in application support, integrations or legacy systems, we'd love to hear from you.
