• Experience with Oracle and/or MongoDB databases.
• Familiarity with Agile, Scrum, or Test-Driven Development practices within a software delivery environment.
• Practical knowledge of modern application architecture, including Microservices frameworks such as Spring Boot, event-driven services, and cloud-native application development.
• Hands-on experience with Web APIs, Kafka, and Git for version control and integration workflows.
• Clear and effective written and verbal communication skills, with the ability to adapt priorities quickly as project needs evolve.

Nice To Haves

• Background in data modelling or data architecture, providing an additional perspective when designing application data layers.
• Demonstrated ability to lead or manage technical workstreams, with experience contributing to project planning and delivery oversight.
• Bachelor's degree or university qualification in a relevant discipline, or equivalent practical experience.

Responsibilities

• Design and develop enhancements to application systems by applying knowledge of software development procedures, analysing existing code, and leveraging scripting tools to deliver reliable, scalable solutions.
• Build and implement programming solutions in collaboration with users, clients, and cross-functional technology teams, ensuring systems meet functional and performance requirements.
• Develop application components to specification, translating design requirements into clean, maintainable code across both front-end and back-end layers.
• Identify and remediate application vulnerabilities through structured security analysis, testing, and debugging to maintain a robust and secure codebase.
• Diagnose and resolve technical issues by drawing on hands-on experience, evaluating available options, and implementing effective solutions with minimal supervision.
• Coach and support junior analysts, sharing technical knowledge and contributing to team capability development.
• Evaluate the risk implications of technical decisions, ensuring all development work aligns with applicable standards, policies, and control requirements.

Benefits

• Access to structured learning and development programmes to keep your technical skills current and support your career progression.
• Exposure to complex, large-scale engineering challenges across a global technology organisation.
