Job description

Responsibilities

1. Partner with solution architects to establish and continuously refine interface specifications and integration frameworks for inbound and outbound data sources using REST APIs, GraphQL, OpenAPI/Swagger, and JSON/XML standards.
2. Design and deliver scalable integration solutions that connect multiple vendors, applications, data platforms, and external subsystems across complex programme environments.
3. Develop and enhance full-stack components using technologies such as Java, Python, JavaScript/TypeScript, React, or Node.js.
4. Build secure, reusable APIs and integration services with Spring Boot, Express.js, API gateways, and microservices-based architectures.
5. Implement reliable data exchange pipelines using Apache Kafka, RabbitMQ, ETL/ELT tools, and event-driven integration patterns.
6. Coordinate technical integration activities across vendors and delivery teams, resolving interface dependencies, data-mapping issues, and cross-system defects.
7. Establish automated build, testing, and deployment workflows through Git, Jenkins, GitLab CI/CD, Docker, and Kubernetes.
8. Validate system interfaces through unit, integration, performance, and end-to-end testing using Postman, JUnit, Selenium, or equivalent tools.
9. Monitor application and integration performance with Splunk, ELK Stack, Grafana, and Prometheus, addressing failures and service bottlenecks proactively.
10. Produce and maintain technical documentation covering interface designs, API contracts, data flows, integration patterns, deployment procedures, and operational support requirements.

Requirements

1. Degree in Computer Science, Engineering, Information Technology, or a related discipline.
2. At least 7 years of experience in systems integration or full-stack engineering for large-scale data or technology platforms.
3. Demonstrated success delivering end-to-end integrations involving multiple vendors, systems, and subsystems within complex, multi-party programme environments.
4. Strong proficiency in API development, microservices, data integration, cloud platforms, event-driven architectures, databases, and modern software engineering practices.
5. Excellent analytical, stakeholder-management, documentation, and problem-solving skills, with the ability to collaborate effectively across architecture, engineering, vendor, and business teams.
