Senior Java Engineer required in South Africa (Remote).

Are you a Java expert with a love for solving real-world challenges? Ready to flex your back-end muscles on complex, large-scale systems — without leaving your home?

We’re looking for a Senior Java Engineer to join a global FinTech team building powerful, multi-market financial systems for clients across the world. You’ll work alongside talented engineers on scalable microservices and robust integrations that keep stockbroking and wealth management operations running smoothly.

Type: Permanent – Remote in South Africa.

Salary: Up to R100k pm (Depending on experience).

What you’ll be doing:

• Designing and building secure, scalable back-end services using Java and Spring Boot
• Creating and maintaining RESTful APIs
• Integrating with messaging tools like Kafka or RabbitMQ
• Working with both relational and NoSQL databases (think Postgres, Cassandra, OpenSearch)
• Streaming data and managing workflows using Kafka and Apache Airflow
• Building testable, reliable systems using JUnit, TestContainers, and BDD tools
• Ensuring strong observability using tools like Prometheus and Grafana
• Collaborating with cross-functional teams across time zones

What you bring:

• Strong Java experience (collections, concurrency, streams, design patterns)
• Deep Spring Boot skills, including Spring Security and Hibernate/JPA
• Solid understanding of REST APIs and microservices in containerised environments (Docker, Kubernetes)
• Experience with Kafka or RabbitMQ
• Hands-on with Postgres and at least one NoSQL database
• Familiar with CI/CD, Git, and modern DevOps practices
• Clear communicator and team player
• Bonus if you’ve touched Scala, Python, or have experience with event-driven systems

Why you’ll love this role:

• You’ll work on real-time financial systems with zero fluff
• Join a down-to-earth team that values autonomy, ownership, and clean code
• Build the kind of software that actually gets used (and relied on) every day
