Job Description & How to Apply Below

Are you a "hands-on" Java Specialist who thrives in high-volume, enterprise environments? We are looking for a Java Developer to join a high-performance team dedicated to building scalable, secure, and automated application architectures.

If you are a technology leader who enjoys working across all tiers of an application—from database management to cloud deployment—this role is for you.

What You’ll Do
  • Architect & Build:
    Lead the end-to-end design, development, and deployment of complex Java applications using Microservices and SOA architectures.
  • Optimize for Scale:
    Solve complex problems related to high-volume environments, including application clustering, multi-threading, and session management.
  • Own the Pipeline:
    Drive development automation by building and maintaining CI/CD pipelines using Azure Dev Ops, Maven, and Nexus.
  • Secure the Flow:
    Implement robust integration protocols (REST, SOAP, MQ) while ensuring top-tier security models like JWT, SSL, and OAuth are airtight.
  • Full-Stack Responsibility:
    Work across different tiers, including front-end (HTML/CSS) and back-end database management (SQL, DB2, Cassandra, Mongo

    DB).
The Tech Stack You’ll Master
  • Languages & Frameworks:
    Java, Spring Boot, Spring Framework, JPA, Hibernate, and Micronaut.
  • Cloud & Containers:
    Docker, Kubernetes (K8s), and orchestrated environments in AWS/Azure.
  • Dev Ops & Tooling:
    Azure Dev Ops, Git, Maven, Sonar Qube, and Nexus.
  • Databases: SQL Server, DB2, and No

    SQL (Cassandra/Mongo

    DB).
  • Architecture: SOA, REST/JSON, SOAP/XML, and Message Queues (MQ).
Your Profile
  • Experience:

    5+ years of solid Java development in a professional, high-volume environment.
  • Agile Mindset:
    Practical exposure to Scrum, Kanban, or SAFe delivery methodologies.
  • Leadership: A self-starter and technology leader who can work independently and solve problems under pressure.
  • Quality Focused:
    Expert in performance monitoring, troubleshooting, and ensuring code quality through tools like Sonar Qube.
  • The "Unicorn" Edge:
    You understand not just the code, but the infrastructure it runs on (Servers, Clusters, and Scaling).
