Build and maintain Java-based microservices, REST APIs, RESTful web services, and reusable platform capabilities.

Develop and maintain database objects, queries, data transformations, conversion routines, and integration workflows using relational databases.

Implement security gateways and protocols, including JSON Web Tokens (JWT), OAuth 2.0, SSL certificates, secure communications, and identity access integrations.

Create and maintain automated unit, integration, API, database, and user-interface test suites.

Participate in design walkthroughs, impact assessments, code reviews, estimation, backlog refinement, and release planning.

Analyze, review, and modify build, configuration, and deployment scripts to optimize CI/CD pipelines.

Troubleshoot and resolve complex technical defects arising during development, deployment, migration, and post-implementation operations.

Collaborate closely with business analysts, architects, UX designers, testers, DevOps engineers, and security specialists across the full software lifecycle.

Prepare comprehensive technical, deployment, system, and user documentation.

Qualifications
Senior Development Leadership: 10+ years of experience designing and developing large-scale, multi-client web applications, or equivalent senior development depth (Strictly Required).

Java & Relational Databases: Extensive hands-on Java development experience working with Oracle, SQL, or comparable relational databases (Strictly Required).
