• Integrate frontend with microservices, APIs, and cloud platforms to maintain seamless data flow, security, and system health.
• Own visualization of tool-calls, lineage, and traces for live agent execution, focusing on usability and accessibility.
• Champion automated testing with Playwright, Cypress, Jest, and TDD for robust, production-grade software.
• Document technical designs, build tools, and developer workflows to support modern DevSecOps practices.
• Mentor junior team members and drive code reviews to uphold engineering best practices and continuous improvement.
• Collaborate cross-functionally in agile teams, balancing new features with technical debt and system performance.

Required Skills and Experience

• Active TS/SCI security clearance with polygraph (MANDATORY).
• Minimum 3 years' professional experience in software engineering, emphasizing modern web app development.
• Expert-level React, TypeScript, and responsive UI/UX development skills.
• Hands-on experience with real-time streaming data, event-driven interfaces (SSE, WebSockets), and state management.
• Proficiency integrating frontend with RESTful/GraphQL APIs and backend microservices.
• Strong background in automated testing (Playwright, Cypress, Jest, TDD) and CI/CD pipelines.
• Deep understanding of Git workflows and secure software delivery.
• Experience building accessible web applications (WCAG standards).

Preferred Skills

• Professional experience with cloud platforms (AWS, Azure, GCP) and Infrastructure as Code (IaC).
• Contributions to large-scale design systems and performance monitoring (Lighthouse, Web Vitals).
• Exposure to GraphQL, Serverless, containerization (Docker, Kubernetes).
• Familiarity with distributed tracing (OpenTelemetry) and AI/agentic, long-running system frontends.
• Consulting or XP/Pair Programming backgrounds.
• Regular use of AI coding assistants with strong verification skills.

Benefits

• Remote-first flexibility with occasional travel to client sites.
• Work at the forefront of AI, agentic systems, and digital transformation for federal customers.
• Inclusive, high-performance engineering culture with strong mentorship and peer support.
• Opportunities for rapid career growth and hands-on experience with advanced technology and security.
• Comprehensive benefits package (medical, dental, vision, retirement, and more).
