Philadelphia, Pennsylvania, United States Lumiere Systems Full time

We are seeking a skilled Java Backend Developer to join our dynamic engineering team. In this role, you will design, develop, and maintain scalable microservices-based applications, integrating various data pipelines and real-time processing systems. You will collaborate with frontend teams, DevOps, and stakeholders to deliver robust, high-performance solutions that drive business value. If you have hands-on experience in building enterprise-grade applications with a focus on backend architecture, this is your opportunity to contribute to innovative projects in a fast-paced environment.

Key Responsibilities

· Design and implement backend services using Java and Spring Boot, ensuring adherence to microservices architecture principles for scalability and maintainability.

· Develop and optimize ETL (Extract, Transform, Load) processes to handle large-scale data ingestion, transformation, and integration from diverse sources.

· Build and manage RESTful APIs and event-driven systems using Kafka for real-time data streaming and asynchronous communication between services.

· Work with relational databases (SQL) and NoSQL databases (MongoDB, GraphDB) to model, query, and persist complex data structures, including graph-based relationships for advanced analytics.

· Collaborate with frontend developers to integrate Angular-based UIs with backend services, ensuring seamless data flow and API compatibility.

· Utilize GitHub for version control, branching strategies, and CI/CD pipelines, while tracking progress and resolving issues via Jira.

· Conduct code reviews, write unit/integration tests, and debug applications to maintain high code quality and performance standards.

· Stay updated with emerging technologies and contribute to architectural decisions for system improvements.

Required Qualifications

· Bachelor's degree in Computer Science, Engineering, or a related field.

· 5+ years of hands-on development experience as a Java Backend Developer, with proven expertise in building and deploying production-ready applications.

· Strong proficiency in Java (JDK 8+), Spring Boot, and microservices frameworks (e.g., Spring Cloud).

· Experience with ETL tools/processes (e.g., Apache NiFi, Talend) and data modeling in SQL (e.g., PostgreSQL, MySQL) and MongoDB.

· Familiarity with Apache Kafka for messaging and event sourcing, and GraphDB (e.g., Neo4j) for handling interconnected data.

· Proficiency in GitHub for collaborative development and Jira for agile project management.

· Solid understanding of Angular for full-stack integration, though primary focus is backend.

· Excellent problem-solving skills, with a track record of delivering features end-to-end in agile environments.

Preferred Skills

· Experience with containerization (Docker, Kubernetes) and cloud platforms (AWS, Azure).

· Knowledge of security best practices (OAuth, JWT) and performance optimization techniques.

· Familiarity with monitoring tools (Prometheus, ELK Stack) and automated testing frameworks (JUnit, Mockito).

· Strong communication skills and ability to mentor junior developers.
