About the Role

We are seeking a high-calibre software engineer to join our backend services team. You will design, build and maintain scalable, reliable microservices powering critical business workflows. You will work with modern API technologies (GraphQL & REST), event-driven systems (message brokers), robust authentication & authorization (OAuth 2.0 / Entra ID), and enterprise-grade Java & Spring Boot frameworks.

Key Responsibilities :

• Design and develop backend services using Java (version 8 or above) and the Spring Boot framework.
• Build and maintain GraphQL endpoints — including schema design, queries, mutations, subscriptions, and optimisations for performance.
• Develop RESTful APIs for integrations and internal consumption.
• Design and implement event-driven / message-based architectures using Apache Kafka (or equivalent like RabbitMQ / Azure Service Bus) to enable asynchronous communication, scalability and decoupling.
• Implement and enforce authentication & authorization using OAuth 2.0 and integrate with Microsoft Entra ID.
• Work in microservices architecture: service discovery, load balancing, resilience, observability and deployment best-practices.
• Collaborate with product owners, front-end teams, DevOps/Platform teams to define APIs, integrate services and deliver high-quality software.
• Ensure code quality: write unit/integration tests, participate in code reviews, follow clean-code and design principles.
• Monitor and tune performance, ensure reliability and operational excellence in production.

Required Skills & Experience :

• Strong experience (X+ years) in Java (version 8 or above) and Spring Boot.
• Solid experience designing and implementing GraphQL APIs (schema, resolvers, performance optimisation).
• Proven experience with RESTful API design and development.
• Experience with event or message-based systems—Kafka or similar (RabbitMQ, Azure Service Bus) in production.
• Proficient with OAuth 2.0 (and optionally OpenID Connect) and working with identity/access management systems (integration with Entra ID or Azure AD).
• Experience in microservices architecture: design, development & deployment.
• Comfortable working with databases (relational and/or NoSQL), version control (Git), CI/CD pipelines, containers (Docker/Kubernetes) is a plus.
• Excellent problem-solving skills, ability to work in a fast-paced environment, strong communication and collaboration skills.

Desirable / Additional Skills :

• Experience with Microsoft Azure (especially Azure AD / Entra ID) and cloud-native patterns.
• Experience with GraphQL federation/gateway setups, subscriptions or real-time data.
• Familiarity with logging, monitoring, metrics, tracing (e.g., Prometheus, Grafana, OpenTelemetry).
• Experience with performance tuning of APIs and message systems at scale.
• Experience working in agile or lean teams.
