The ideal candidate thrives in aggressive, high-velocity delivery environments, has a proven track record of migrating legacy enterprise systems, values proactive team leadership, and actively leverages modern AI-assisted engineering tools to accelerate software development lifecycles without sacrificing code quality. Candidates must be a U.S. Citizen with an active Department of Treasury MBI.

Requirements

• 10–12 years of professional experience in enterprise-grade software engineering, with a strong emphasis on system transformations, refactoring legacy codebases, and application modernization strategies.
• JavaScript (ES6+), HTML5, CSS3.
• React.js, Redux (or Redux Toolkit)
• VS Code, NPM.
• Java, Spring Boot, Spring Security.
• Spring Batch (Job, Step, Chunk-based processing configurations).
• JPA / Hibernate, Oracle DB (SQL optimization, indexing, migrating legacy stored procedures), and H2 Database (for in-memory testing).
• Eclipse IDE, Maven.
• JUnit 5 and Mockito for structural logic isolation, stubbing behaviors, and legacy code behavioral verification.
• Jest and React Testing Library for UI isolation and state tracking.
• Strong hands-on experience building and maintaining automated UI regression suites using tools like Selenium WebDriver (Java or JavaScript bindings).
• AWS (Amazon Web Services) and OpenShift Container Platform (OCP).
• GitHub Actions workflow orchestration (integrating automated execution of unit, mocking, and Selenium testing blocks).
• Docker / container lifecycle management.
• Git, GitHub, GitLab
• Practical experience using GitHub Copilot, ChatGPT, or Claude for syntax generation, deciphering legacy code patterns, query optimization, and rapid debugging.
• U.S. Citizen with an active Department of Treasury MBI.

Nice To Haves

• Experience building or maintaining automated internal workflows using tools such as UiPath or Microsoft PowerApps.
• Proven experience delivering production-grade code within fast-paced, highly demanding corporate settings.
• Ability to safely lead teams through architectural paradigms shifts without disrupting day-to-day business operations.
• Active participant and leader in peer code reviews, architectural discussions, and cross-functional troubleshooting sessions.
• Ability to articulate complex backend or deployment blockers concisely to non-technical stakeholders.

Responsibilities

• Analyze, decouple, and migrate legacy enterprise systems (monoliths, older Java frameworks, complex store procedures) into a clean, decoupled microservices or modular architecture.
• Design and optimize highly responsive web UIs using React, transforming legacy server-rendered views or desktop applications into sleek interfaces while managing complex client-side caching via Redux.
• Build secure, high-throughput RESTful services using Java and Spring Boot, while implementing automated, high-volume bulk data pipelines via Spring Batch to replace outdated legacy batch processing routines.
• Model structured corporate data using JPA and Hibernate ORM to bridge legacy data stores with modern Oracle production databases.
• Author and maintain automated end-to-end testing frameworks, mock environments, and isolation tests using Selenium, JUnit 5, and Mockito to ensure zero regressions during modernization phases.
• Author and maintain automated CI/CD workflows using GitHub Actions to cleanly package, containerize, and deploy modernized services across AWS Cloud and OpenShift Container Platform environments.
• Integrate generative AI tools (GitHub Copilot, ChatGPT, Claude) into daily workflows to drastically accelerate boilerplate generation, legacy code refactoring, and query optimization.
• Partner closely with architectural leads, product owners, and QA engineers within highly demanding Sprint cycles to ship reliable, well-documented code under tight deadlines.
