Backend Developer

The Backend Developer at our company will be responsible for designing and developing microservices using Spring Boot and creating RESTful APIs. They will work on integrating AI model services for real-time JSON data processing and ensure seamless communication between services using technologies such as gRPC and Kafka. Additionally, they will manage database design, data caching strategies, and implement security measures to protect sensitive data.

Candidates should have strong proficiency in Java 9+, with practical experience in Spring Boot and Spring Cloud. It's essential to have experience with both SQL and NoSQL databases, event-driven architectures, and real-time communication using WebSockets. Candidates familiar with Docker, Kubernetes, CI/CD processes, and cloud platforms will stand out. Knowledge of security best practices and performance optimization will also be crucial for this role.

In this Backend Developer role, familiarity with Spring Boot, RESTful APIs, and event-driven systems like Kafka or RabbitMQ is crucial. Additionally, you'll need expertise in various databases (PostgreSQL, MySQL, MongoDB) and experience with Docker and Kubernetes for deployment. Knowledge about monitoring tools like Prometheus or Grafana and security practices such as OAuth2 and JWT will also be required.

While extensive experience in AI or machine learning is not required, familiarity with AI model integration and real-time data processing will be beneficial. Understanding how to work with AI-powered systems can help in effectively managing data workflows and enhancing the functionality of our warehouse automation project.

This position is an on-site contract role based in Ridgefield Park, NJ, and is expected to last for approximately three months. We provide a collaborative environment and the opportunity to work on innovative technology projects that are at the forefront of industry advancement.
