- Build and maintain seamless integrations between microservices and existing cloud infrastructure, ensuring reliability, performance, and alignment with architectural standards.
- Contribute to the full development lifecycle for new features within the identity innovation space, from technical design and implementation through to testing and deployment.
- Collaborate with engineering and business teams to translate requirements into well-defined technical specifications and clearly articulate application and system processes.
- Implement solutions that meet audit and security requirements, working alongside information security teams to maintain compliance with applicable standards.
- Participate in code reviews and support the technical development of junior engineers, contributing to a culture of engineering excellence and continuous improvement.
- Evaluate technical decisions with a clear understanding of risk, ensuring solutions uphold the firm's standards for quality, security, and regulatory compliance.
Required Qualifications & Skills
- Hands-on experience in Java software development with deep proficiency in Core Java and the Spring Framework, including Spring Core, Spring Security, and Spring Data.
- Practical experience building and consuming RESTful and SOAP web services, with a solid grasp of microservices architecture principles and patterns.
- Competence across the core development toolchain, including Maven or Gradle for builds, Git for version control, and testing frameworks such as JUnit, Mockito, AssertJ, and Cucumber.
- Experience working with relational databases (Oracle, PostgreSQL) and NoSQL databases (MongoDB), and familiarity with logging frameworks such as SLF4J or Log4j.
- Demonstrated ability to containerise and orchestrate applications using Docker and Kubernetes, and to work within CI/CD pipeline environments.
- Experience with event-driven architectures using Kafka or equivalent message queuing technologies.
- Ability to manage competing priorities independently, take ownership of project components end-to-end, and communicate technical decisions clearly to both technical and non-technical audiences.
- Bachelor's degree in Computer Science, Engineering, or a related field, or equivalent professional experience.
Beneficial Skills & Qualifications
- Working knowledge of Python, enabling contribution to automation tasks or scripting where Java is not the primary tool.
- Familiarity with JVM performance tuning and application profiling, with the ability to identify and resolve bottlenecks in production environments.
- Prior experience working within financial services or another large, regulated, global organisation.
