Front-End Software Engineer (ReactJs)

The Judge Group is seeking a Front-End Software Engineer for a large federal project. The role involves building user interfaces with React, TypeScript, and Tailwind CSS, integrating AI development tools and AWS services. US citizenship is required.

• Design, develop, and deploy scalable, highly responsive user interfaces using ReactJS, JavaScript, and TypeScript.
• Implement modern, accessible, and maintainable styling and UI components utilizing Tailwind CSS, shadcn (or experience with other component libraries)
• Utilize Vite for rapid frontend tooling, building, and optimized application bundling.
• Collaborate with backend developers to integrate Python-based RESTful APIs and ML models into frontend applications.
• Incorporate agentic tools (e.g., Claude Code, Antigravity, Kiro) into daily development workflows to accelerate coding, testing, and deployment.
• Leverage AWS Services including S3, CloudFront, API Gateway, and others to deploy and manage frontend applications.
• Collaborate with cross-functional teams to integrate AI capabilities—such as chatbots, Retrieval-Augmented Generation (RAG) interfaces, and intelligent search—into web applications.
• Contribute to the team's software architecture design, ensuring frontend solutions are scalable, reliable, secure, and performant.
• Rapidly prototype UI/UX concepts and iterate on solutions for mission-critical challenges in areas such as data triage, operational decision-making, and automated discovery.

• Bachelor’s degree is required.
• Minimum FIVE (5) years of hands-on experience in software engineering, focusing on Front-End development. A master’s degree OR Industry Certification may be substituted for up to two years of relevant professional experience.
• Demonstrated experience building Section 508 compliant and accessible user interfaces, with a strong understanding of WCAG 2.1/2.2 guidelines and accessible rich internet applications (ARIA) standards.
• Deep expertise in JavaScript and TypeScript, with a strong focus on ReactJS for building complex, interactive, and accessible user interfaces.
• Hands-on experience with modern frontend build tools and styling frameworks, specifically Vite, Tailwind CSS, shadcn/Radix UI, or other component libraries.
• Working knowledge of Python to effectively interface with backend APIs, ML models, and systems integration.
• Solid foundational knowledge of Artificial Intelligence concepts, with experience integrating AI/ML APIs, LLMs, or conversational agents into web applications.
• Proven experience deploying and managing frontend web applications using AWS services (S3, CloudFront, API Gateway, etc.).
• Strong knowledge of REST API design, state management, and modern UI/UX principles.
• Strong analytical, problem-solving, and communication skills, with the ability to translate complex mission needs into intuitive software solutions.
• Experience with GenAI-assisted UI development and rapid prototyping using AI generation tools.
• Familiarity with building and optimizing frontends for Retrieval-Augmented Generation (RAG) applications or complex AI chatbots.
• Experience with AWS serverless architectures (e.g., AWS Lambda) and infrastructure-as-code tools (e.g., Terraform, AWS CDK).
• Experience designing UI/UX workflows that support human-in-the-loop review, case prioritization, and explainable AI outputs.
• Knowledge of automated testing frameworks (e.g., Jest, Cypress, Playwright) within an AI-assisted CI/CD pipeline.

• Medical, dental, and vision insurance are available to qualified candidates who meet eligibility requirements.
