Renmoney, a premier fintech and consumer lending institution dedicated to driving financial inclusion across Nigeria through advanced loans, savings, and fixed deposit solutions, is recruiting a full-time Java Developer. Based on-site at the corporate headquarters in Lagos, this core software engineering position is embedded within vital business units—such as Core Banking, Loans, Tech Platform, or Cards—to scale high-performance backend infrastructure.

The Java Developer will architect, build, and maintain mission-critical backend microservices that power millions of financial transactions. Combining robust Java/Spring Boot development, Kafka-driven event architectures, AWS cloud deployments, and advanced system observability tools, this role focuses on software craftsmanship, clean architecture, and reliable distributed system design.

• Backend Engineering: Design, build, test, and deploy resilient, highly scalable backend applications utilizing Java and the Spring Boot framework.

• Microservices Development: Create and optimize production-ready RESTful APIs and decoupled microservices architectures to process high-throughput transaction pipelines.

• Event-Driven Architecture: Implement distributed streaming, data pipelines, and real-time messaging workflows using Apache Kafka.

• Cloud & Infrastructure Alignment: Deploy and maintain containerized distributed systems within cloud-native environments, specifically leveraging AWS and Amazon EKS.

• Database & Caching Management: Structure scalable database schemas within MySQL relational engines and optimize system latency using Redis caching.

• Observability & Maintenance: Monitor system health, debug complex performance bottlenecks, and configure active tracing using Grafana and Prometheus ecosystems.

• Collaborative Governance: Participate in rigorous technical design reviews, cross-team alignment sessions, and automated unit/integration testing frameworks.

• Education: Bachelor's degree in Computer Science, Software Engineering, Information Technology, or a related quantitative engineering discipline.

• Experience Baseline: Proven professional track record building, shipping, and maintaining distributed backend systems in production environments using Java.

• Domain Advantage: Direct experience engineering core components within a Fintech, digital payments, retail banking, or lending ecosystem is a strong advantage.

• Core Technical Stack:

  • Advanced proficiency in Java and the Spring Boot framework.

  • Practical development experience building RESTful APIs and distributed microservices.

  • Sound operational knowledge of AWS cloud orchestration (specifically Amazon EKS).

  • Hands-on experience with MySQL (relational) and Redis (in-memory caching).

  • Direct familiarity with Kafka for message streaming and event-driven patterns.

  • Exposure to modern monitoring frameworks, including Grafana and Prometheus.

• Professional Attributes: Strong analytical problem-solving skills, dedication to clean code practices, and an eagerness to work in an open, team-oriented workspace.

• Opportunity to work at an innovative, globally scaled fintech firm.

• Daily exposure to a premium modern tech stack (Java, Spring Boot, AWS EKS, Kafka, Redis, Prometheus).

• Competitive compensation packages alongside accelerated career growth paths.
