Professional Job Description
Seeking an enterprise-level Principal Java Engineer with 12+ years of software engineering experience for a 6-month contract role in New Jersey (Hybrid setup). The candidate will provide hands-on technical leadership, architectural guidance, and critical code development for large-scale distributed systems and enterprise application modernization initiatives. 
This role demands expert-level mastery in core Java/JDK, Spring Boot, Microservices, event-driven architecture (Kafka), cloud platforms (Azure or AWS), and container orchestration (Docker/Kubernetes).

#Key Responsibilities

* DevSecOps & Performance Engineering: Oversee CI/CD pipelines (GitHub Actions/Jenkins/Azure DevOps), enforce SonarQube quality gates, perform deep-dive performance tuning, and lead root-cause analysis (RCA) on production incidents.
* Data & Observability Architecture: Design data models across relational databases (PostgreSQL, Oracle, SQL Server) and NoSQL engines (MongoDB/Redis), while establishing full-stack observability (Dynatrace, Splunk, OpenTelemetry).

#Required Qualifications
* Core Experience: 12+ years of progressive software engineering experience building complex, high-concurrency enterprise Java systems.
* Primary Tech Stack: Expert-level proficiency in Java/JDK, Spring Framework, Spring Boot, and distributed Microservices architecture.
* Messaging & Cloud Containerization: Demonstrated expertise with Kafka, REST APIs, Docker, Kubernetes, and cloud engineering on Azure or AWS.
