• Mentor and support other developers within the team
• Stay up to date with emerging technologies and contribute to continuous improvement initiatives

• Strong experience with:
  • Java (8+)
  • Spring framework
  • Relational databases (e.g. SQL Server, Oracle)
  • Git version control
• Solid understanding of object-oriented programming principles
• Experience supporting production systems in a live environment
• Strong analytical and problem-solving skills
• Ability to work independently and as part of a team

Desirable Experience

• Kafka
• ORM tools (e.g. Jooq, NHibernate, Entity Framework)
• C#
• Automated testing frameworks
• MVC / MVP design patterns
• CI/CD tools (e.g. Jenkins, Azure DevOps, GitHub Actions)
• Deployment tools (e.g. Ansible, Puppet, Chef)

What’s in it for you?

• Opportunity to work on impactful, business-critical systems
• A collaborative and supportive development environment
• Clear progression pathway (including opportunities to move into senior/architect-level roles)
• Ongoing training and development

About You

You’re a proactive and analytical developer who takes ownership of your work. You enjoy collaborating with others, mentoring where needed, and continuously improving both your technical skills and the systems you work on.
