MUST BE A US CITIZEN OR GC HOLDER

Key Responsibilities

• Database development: Develop, debug, maintain, and tune SQL, complex stored procedures, views, triggers, and related database business logic.
• Java Development: Develop and maintain Spring Boot services, REST APIs, message-based integrations, batch processes, and supporting service-layer code.
• Production support: Investigate application issues, data discrepancies, failed integrations, and production incidents, including weekly on-call rotation.
• Integration support: Support IBM MQ, APIs, messaging, file-transfer, notification, and scheduled-processing workflows across connected application systems.
• Reliability improvements: Improve performance, stability, logging, maintainability, availability, and recovery across database and Java components.
• Legacy Application Maintenance: Diagnose defects, trace existing business logic, implement targeted fixes and enhancements, refactor Java and database code carefully, and improve performance without disrupting existing integrations.
• Testing and review: Test, debug, review, and validate database and Java changes before release according to established procedures.
• Cross-team collaboration: Work with analysts, testers, DBAs, developers, and operations staff to deliver reliable changes.

Requirements

• Experience level: 3-5 years of professional experience developing and supporting Java applications and relational databases, including significant hands-on relational database development.
• Java and Spring Boot: Ability to develop and maintain Spring Boot services, REST APIs, Spring batch processes, JDBC/JPA access, and configuration.
• Application integration and distributed systems: Experience supporting REST APIs, IBM MQ or another enterprise messaging platform, message-based workflows, scheduled jobs, secure transfers, and application logs, with an understanding of service dependencies, failover, retries, timeouts, idempotency, and recovery.
• SQL and database skills: Significant hands-on experience developing, debugging, and maintaining complex stored procedures and database business logic, including triggers, views, joins, scripts, query tuning, and data reconciliation.
• Database platform experience: Working knowledge of SAP ASE/Sybase or a comparable relational database platform.
• Production support: Ability to diagnose issues, communicate status clearly, and deliver accurate fixes with minimal oversight.
• Build and testing: Working knowledge of Maven, unit testing, mocking frameworks, and code review practices.
• Communication and ownership: Ability to explain technical findings and take ownership of complete, tested work.

Preferred Technology and Experience

• Modern Java stack: Java 17 or newer, Spring Boot 3.x, Spring Web, Spring Batch, JDBC/JPA, REST APIs, messaging, monitoring, and structured logging.
• Database connectivity and operations: JDBC, connection pooling, multiple data source configuration, and production database troubleshooting.
• Integration patterns: API integration, message-based processing, stored procedure integration, scheduling, email, file publishing, and FTP/SFTP-style support.
• Database Stack: Experience with Microsoft SQL Server T-SQL, Oracle PL/SQL, or another comparable procedural SQL environment may be considered transferable to SAP ASE/Sybase.

Supplementary Technical Experience

• Containers & Orchestration: Docker containerization with familiarity in Kubernetes or OpenShift.
• CI/CD & Version Control: Git, Jenkins, Azure DevOps, GitHub Actions, or comparable automation tools.
• Observability & Logging: Application monitoring using Splunk, ELK stack, Prometheus, Grafana, OpenTelemetry, or distributed tracing.
• Application Security: OAuth2/OIDC, JWT, mutual TLS, certificates, and secrets management.
• Integration Testing & Mocking: Testcontainers, WireMock, contract testing, Selenium, or Cypress.
• System Scripting & Operations: Linux/Unix shell scripting, PowerShell, load testing, or capacity planning.
• Frontend Exposure: Familiarity with React, Angular, Vue, TypeScript, HTML, or CSS for end-to-end troubleshooting.
