Full Stack Engineer

Responsibilities

• 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.

• Design and deliver scalable integration solutions that connect multiple vendors, applications, data platforms, and external subsystems across complex programme environments.

• Develop and enhance full-stack components using technologies such as Java, Python, JavaScript/TypeScript, React, or Node.js.

• Build secure, reusable APIs and integration services with Spring Boot, Express.js, API gateways, and microservices-based architectures.

• Implement reliable data exchange pipelines using Apache Kafka, RabbitMQ, ETL/ELT tools, and event-driven integration patterns.

• Coordinate technical integration activities across vendors and delivery teams, resolving interface dependencies, data-mapping issues, and cross-system defects.

• Establish automated build, testing, and deployment workflows through Git, Jenkins, GitLab CI/CD, Docker, and Kubernetes.

• Validate system interfaces through unit, integration, performance, and end-to-end testing using Postman, JUnit, Selenium, or equivalent tools.

• Monitor application and integration performance with Splunk, ELK Stack, Grafana, and Prometheus, addressing failures and service bottlenecks proactively.

• Produce and maintain technical documentation covering interface designs, API contracts, data flows, integration patterns, deployment procedures, and operational support requirements.

Requirements

• Degree in Computer Science, Engineering, Information Technology, or a related discipline.

• At least 7 years of experience in systems integration or full-stack engineering for large-scale data or technology platforms.

• Demonstrated success delivering end-to-end integrations involving multiple vendors, systems, and subsystems within complex, multi-party programme environments.

• Strong proficiency in API development, microservices, data integration, cloud platforms, event-driven architectures, databases, and modern software engineering practices.

• Excellent analytical, stakeholder-management, documentation, and problem-solving skills, with the ability to collaborate effectively across architecture, engineering, vendor, and business teams.
