Job description

DeARX is looking for an experienced Senior Java Developer to join a leading financial services technology environment in Sandton on an initial 12-month contract.

This is an opportunity for a hands-on Java engineer to work on enterprise-scale, high-volume applications, contributing across the full software development lifecycle—from technical design and development through testing, deployment, optimisation and production support.

You’ll work within an Agile technology environment alongside experienced technical and delivery teams, with the opportunity to work across modern Java, Spring Boot, Microservices, Cloud, Kubernetes and DevOps technologies.

What You’ll Be Doing

• Design, develop, test, deploy and support high-quality Java applications.
• Build and enhance scalable Spring Boot, Spring, JPA and Hibernate solutions.
• Work within Microservices and SOA architectures and develop enterprise APIs and integrations.
• Take ownership of deliverables from technical design through development, testing, deployment and production support.
• Develop secure and reliable integrations using REST, SOAP, JSON, XML and messaging technologies.
• Contribute to automated CI/CD and DevOps pipelines and continuous delivery practices.
• Perform unit testing, code reviews, troubleshooting and performance optimisation.
• Work with cloud and containerised environments including Azure/AWS, Docker and Kubernetes.
• Collaborate with Scrum Masters, Product Owners, Delivery Leads and technical SMEs within Agile delivery teams.
• Contribute to the ongoing support, maintenance and improvement of critical enterprise applications.

What We’re Looking For

We’re looking for a developer who is genuinely hands-on, analytical and technically curious, with the ability to work independently and take ownership of complex technical problems.

You Should Have

• 5+ years' professional software development experience, with strong Java experience.
• Strong hands-on experience with Java, Spring Framework and Spring Boot.
• Solid experience with JPA and Hibernate and ideally Micronaut.
• Strong understanding of Object-Oriented Design and software engineering principles.
• Experience building Microservices and/or SOA-based solutions.
• Strong API and integration experience across REST and SOAP.
• Experience with application security including JWT and SSL/TLS.
• Experience working with relational databases such as SQL/DB2 and exposure to NoSQL technologies such as MongoDB or Cassandra.
• Experience with Docker and Kubernetes and exposure to Azure and/or AWS.
• Strong understanding of CI/CD, DevOps and deployment automation.
• Experience with Git, Maven and code-quality tools such as SonarQube.
• Experience working with enterprise application environments and production systems.
• Experience with application performance monitoring, troubleshooting and optimisation.
• Practical understanding of high-volume systems, including scalability, clustering, concurrency and performance.
• Experience working in Agile environments, including Scrum, Kanban and/or SAFe.

The Technical Environment

You’ll have the opportunity to work across technologies including Java | Spring | Spring Boot | JPA | Hibernate | Micronaut | Microservices | REST | SOAP | MQ | Docker | Kubernetes | Azure | AWS | Git | Maven | Jenkins | Azure DevOps | SonarQube | CI/CD.

What Will Make You Stand Out?

We’re particularly interested in developers who bring more than just coding skills.

• Experience in banking, financial services or other high-volume enterprise environments.
• Strong system design and architecture capability.
• Experience working on complex, integrated enterprise platforms.
• Strong cloud-native development experience across Azure and/or AWS.
• Deep Spring Boot and Microservices expertise.
• Experience solving complex production and performance problems.
• A strong focus on code quality, security and engineering standards.
• The ability to understand the bigger picture while still being comfortable getting hands-on with the code.
