We are seeking a skilled Backend Developer to join our team on a 1‑year fixed-term contract. In this role, you will design, build, and optimize high‑performance backend services using Core Java and Spring Boot, with a strong emphasis on multithreading, concurrency, and scalable microservices.

You will contribute to the development of AI‑enabled and agentic systems, support distributed architectures, and partner with cross‑functional teams to deliver resilient, low‑latency solutions. This is an ideal opportunity for someone who enjoys solving complex backend problems, working close to the JVM, and applying modern engineering and AI-driven patterns at scale.

What will your typical day look like?

• Design, develop, and maintain backend services and APIs using Core Java (8/11/17+), Spring, and Spring Boot, applying advanced multithreading and concurrency patterns to build high‑throughput, low‑latency systems.
• Contribute to agentic AI–enabled backend workflows, supporting Java-based AI orchestration, service coordination, and intelligent processing within distributed environments.
• Work within a microservices architecture, integrating RESTful services, messaging platforms (Kafka/RabbitMQ), and relational databases while ensuring scalability and clean separation of concerns.
• Diagnose and resolve performance bottlenecks through profiling, JVM tuning, thread pool optimization, and garbage collection analysis, improving system reliability and throughput.
• Collaborate with frontend and full‑stack teams by supporting backend integrations with HTML, Angular, and TypeScript applications, ensuring efficient API design and data contracts.
• Implement unit, integration, and performance testing, contribute to CI/CD pipelines, and support deployment within containerized environments.
• Enhance service observability and resilience through logging, metrics, tracing, and fault‑tolerant patterns, while contributing to secure coding practices and technical documentation
