Backend Developer
General Description:
We are developing an AI-powered warehouse automation system where multiple cameras capture images of packages, store them on Servers, and process them through three AI models. The AI models return results in JSON format, which are stored in a database and provided to auditors via a web-based application.
To build a scalable and efficient system, we are adopting a Java-based Microservices Architecture (MSA). We are looking for a highly skilled Back-End Developer with expertise in Spring Boot, RESTful APIs, WebSockets, event-driven systems, and cloud-native architectures.

Essential Responsibilities:

• Design & Develop Microservices:

o Implement scalable, high-performance microservices using Spring Boot.
o Develop RESTful APIs and WebSocket communication for real-time data streaming.
o Integrate AI model services to handle real-time JSON data processing.

o Ensure modularity and independence of services to support scalability and maintainability.

• Service Communication & Integration:

o Implement inter-service communication using REST, gRPC, and Kafka/RabbitMQ.
o Manage asynchronous messaging for AI model requests and results processing.
o Develop real-time WebSocket-based messaging for UI interactions and live updates.

o Integrate with external storage solutions for image management and AI processing workflows.

• Database & Data Management:

o Design and optimize relational (PostgreSQL/MySQL) and NoSQL (MongoDB/Elasticsearch) databases.
o Implement data caching strategies using Redis to improve response times.

o Develop efficient queries and indexing strategies for fast data retrieval.

• Security & API Management:

o Implement OAuth2, JWT authentication, and Role-Based Access Control (RBAC).
o Ensure secure API development and protect against vulnerabilities (OWASP standards).

o Secure WebSocket connections and manage authentication for real-time data streaming.

• Performance Optimization & Monitoring:

o Optimize system performance through profiling, load balancing, and caching mechanisms.
o Implement observability tools like Prometheus, Grafana, ELK Stack, and Zipkin.

o Design fault-tolerant mechanisms for service recovery and failover strategies.

• CI/CD & Cloud Deployment:

o Implement CI/CD pipelines using Jenkins, GitHub Actions, or GitLab CI/CD.
o Deploy microservices in Docker containers and manage orchestration using Kubernetes (K8s).
o Work with Terraform/Ansible for infrastructure automation.
