We are looking for a highly experienced Master Java Developer and Architect to lead the design and development of a secure, high-performance back-end information broker. This role will focus on creating a robust client-server architecture that can access and integrate with over a dozen remote legacy applications and services, facilitating efficient and secure data exchange and real-time processing. The ideal candidate will possess deep expertise in Java, the Spring framework, and event-driven architecture, as well as strong experience in messaging systems, secure data handling, and server-side development.
As a key architect and developer, you will play a critical role in building an innovative, resilient, and secure back-end system capable of meeting high performance and security standards while seamlessly connecting to diverse legacy systems.
Key Responsibilities
• Architect and Design: Define and implement the architecture for a scalable, secure, and high-performance back-end information broker, facilitating data exchange with 15 legacy applications.
• Java Development: Develop optimized, high-quality Java code to support core back-end functionality, focusing on reliability, security, and performance.
• Spring Framework: Utilize Spring Boot, Spring Security, Spring Data, and other Spring components to create a modular and robust client-server application.
• Event Processing and Messaging: Design and implement an event-driven architecture using high-performance messaging systems for real-time data integration and processing.
• Legacy System Integration: Develop secure adapters and interfaces to access and interact with various remote legacy systems, handling compatibility and performance challenges.
• Security Implementation: Ensure robust security protocols across the architecture, including secure data transmission, encryption, and authentication/authorization frameworks.
• Performance Tuning: Conduct performance assessments and optimizations to handle large volumes of data with low-latency processing.
• Documentation: Prepare and maintain technical documentation to support development, integration, testing, and deployment.
• Collaboration: Work closely with cross-functional teams, including database administrators, front-end developers, and system architects, to ensure seamless end-to-end integration.
Required Qualifications
• Mastery in Java Development with a minimum of 8-10 years of experience, specializing in back-end server applications.
• Advanced Spring Framework Knowledge: Expertise with Spring Boot, Spring Data, and Spring Security to implement efficient, secure, and modular server-side applications.
• Event-Driven Architecture: Proficiency in using event-driven frameworks and technologies such as:
o Apache Kafka: For high-throughput, low-latency event streaming.
o RabbitMQ: For reliable message queuing and routing.
o Apache ActiveMQ: To support messaging across legacy systems and protocols.
• High-Performance Messaging Systems: Experience with messaging systems such as:
o ZeroMQ: For low-latency messaging between distributed services.
o Apache Pulsar: For distributed, high-performance messaging.
o IBM MQ: For enterprise-grade messaging, particularly in legacy environments.
• Legacy System Integration: Proficiency in integration tools such as:
o Apache Camel: To manage complex integrations and mediation.
o Spring Integration: For seamless connection to various remote services.
• Web Services and APIs: Expertise in secure RESTful API development, along with experience using tools like:
o Swagger/OpenAPI: For API design, documentation, and testing.
o Postman: For API testing and security validation.
• Remote Data Access and Caching: Knowledge of remote data access protocols and caching solutions:
o gRPC or Thrift: For efficient, high-performance server-to-server communication.
o Redis: To enhance data retrieval speed and reduce latency.
• Data Transmission Security: Expertise in implementing TLS/SSL for secure data transit.
• Authentication and Authorization: Experience with Spring Security, including role-based access control (RBAC) and frameworks like OAuth 2.0 and JWT.
• Encryption and Access Control: Knowledge of encryption standards (e.g., AES, RSA) for secure data at rest and in transit, along with robust access control measures.
• Security Auditing and Logging: Experience with secure logging and monitoring using tools like the ELK Stack (Elasticsearch, Logstash, Kibana) to detect and respond to security events.
• Compliance with Security Standards: Knowledge of industry security standards and regulations (e.g., NIST, ISO 27001) to ensure a secure client-server architecture.
