• We are looking for a Backend Engineer to join our growing software development team. In this role, you will design, build, and maintain the backend services that power our digital products and internal platforms—serving millions of customers and processing high volumes of transactions daily.
• You will work primarily with Java and Go, and collaborate closely with frontend engineers, platform/infrastructure teams, architects, and product owners to deliver secure, high-performance, and maintainable services. The ideal candidate brings strong fundamentals in distributed systems, a bias for clean code, and a genuine interest in solving complex problems at scale within a regulated financial services environment.

Key Responsibilities

Design & Development

• Design, develop, test, and maintain backend services and RESTful/gRPC APIs that are secure, performant, and well-documented
• Build and evolve microservices using Java (Spring Boot) and Go, following domain-driven design and clean architecture principles
• Implement event-driven workflows using message brokers (Apache Kafka, RabbitMQ) for asynchronous processing, notifications, and system integration
• Write clean, reusable, and well-tested code with meaningful unit, integration, and contract tests
• Translate business and user requirements into well-structured technical solutions, contributing to design documents and architecture decision records (ADRs)
• Data & Integration
• Design and optimize relational database schemas (PostgreSQL, MySQL, Oracle) and work with ORMs such as Hibernate/JPA
• Implement caching strategies using Redis to improve response times and reduce database load
• Integrate with third-party systems and payment gateways (M-PESA, card networks, SWIFT) via REST APIs, SOAP, and messaging protocols
• Work with data serialization formats including JSON, XML, Protocol Buffers, and Avro for inter-service communication
• Quality & DevOps
• Conduct thorough code reviews, providing constructive feedback to maintain code quality and consistency across the team
• Build and maintain CI/CD pipelines (Jenkins, GitHub Actions, GitLab CI) for automated testing, building, and deployment
• Containerize services using Docker and deploy to orchestrated environments (Kubernetes/EKS)
• Implement structured logging, metrics, and distributed tracing (ELK Stack, Prometheus, Grafana, Jaeger) for observability and debugging in production
• Participate in on-call rotations and incident response, conducting root cause analysis and implementing preventive measures
• Security & Compliance
• Implement authentication and authorization patterns (OAuth 2.0, JWT, OpenID Connect) following security best practices
• Apply secure coding practices aligned with OWASP guidelines and participate in security reviews
• Ensure services comply with internal architecture standards, audit requirements, and regulatory guidelines applicable to financial services
• Collaboration & Growth
• Collaborate with cross-functional teams—frontend, QA, DevOps, architecture, product—in Agile/Scrum ceremonies (sprint planning, standups, retrospectives)
• Mentor junior developers and contribute to internal knowledge-sharing through documentation, tech talks, and pair programming
• Stay current with industry trends and evaluate new tools, frameworks, and patterns that could improve team productivity and system quality

Required Qualifications

Education & Experience

• Bachelor’s degree in Computer Science, Software Engineering, Information Technology, or a related field
• Minimum 3 years of professional experience in backend software development with production systems
• Demonstrated experience building and maintaining services in a microservices or service-oriented architecture
• Technical Competencies
