We are dedicated to delivering innovative solutions that support the critical missions of our government clients.This opportunity is 100% remote.We are looking for a Senior Full-Stack Developer to join our fast-paced enterprise engineering team. In this senior-level role, you will champion legacy modernization initiatives, systematically breaking down monolithic architectures, legacy databases, and older web frameworks into high-transaction web interfaces and scalable, modern backend solutions across dynamic hybrid infrastructure setups (On-Premises OpenShift & AWS Cloud).The ideal candidate thrives in aggressive, high-velocity delivery environments, possesses 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.Core Responsibilities

• Legacy Modernization: Analyze, decouple, and migrate legacy enterprise systems (monoliths, older Java frameworks, complex store procedures) into a clean, decoupled microservices or modular architecture.
• Front-End 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.
• Back-End Engineering: 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using Java and Spring Boot, while implementing automated, high-volume bulk data pipelines via Spring Batch to replace outdated legacy batch processing routines.
• Data Migration & Management: Model structured corporate data using JPA and Hibernate ORM to bridge legacy data stores with modern Oracle production databases.
• Test Automation Execution: 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.
• Hybrid Infrastructure & DevOps: 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.
• AI-Driven Delivery: Integrate generative AI tools (GitHub Copilot, ChatGPT, Claude) into daily workflows to drastically accelerate boilerplate generation, legacy code refactoring, and query optimization.
• Agile Collaboration: Partner closely with architectural leads, product owners, and QA engineers within highly demanding Sprint cycles to ship reliable, well-documented code under tight deadlines.

Technical Skills RequiredExperience Level & Expertise

• 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.

Presentation & Layout Layer
