• Build, enhance and support critical bespoke applications, contributing to application design, development and ongoing maintenance.
• Manage Linux and Windows infrastructure, including databases, virtualised environments and system health monitoring.
• Investigate and resolve application and infrastructure issues, ensuring system stability, performance and availability.

• Software development experience, ideally with Python
• Strong SQL and relational database knowledge
• Good understanding of software development principles

The opportunity:

You’ll work closely with technical and operational teams supporting systems where reliability and resilience are critical. The role offers a varied mix of application development, infrastructure, troubleshooting and operational support, rather than focusing on one specific technology.

You’ll also have the opportunity to work on technology supporting the fight against organised crime, collaborating directly with operational users and partner agencies.
