About the Organization
Now is a great time to join Redhorse Corporation. We are a solution-driven company delivering data insights and technology solutions to customers with missions critical to U.S. national interests. We’re looking for thoughtful, skilled professionals who thrive as trusted partners building technology-agnostic solutions and want to apply their talents supporting customers with difficult and important mission sets.

About the Role

Redhorse transforms the way the government uses data and technology. We are seeking "Everything Engineers" (Full-Stack Software Engineers with a Frontend Focus) to modernize a mission-critical legacy system managing billions of dollars in U.S. international security cooperation.

This isn't a traditional coding role; we utilize an Agentic AI Software Development Lifecycle. You will work alongside AI agents (Codex, Claude Code) to replace a decades-old system with a modern, humane web platform. You will build complete vertical slices of business capability—from UI and API to database and infrastructure—ensuring our national security partners have the best tools available.

Key Responsibilities

    • Agentic Development: Decompose complex problems into precise specifications that AI agents can implement, owning the final output through rigorous human review.
    • Full-Stack Execution: Build and maintain vertical slices of capability including React frontends, Node services, Prisma schemas, and AWS infrastructure.
    • Frontend Mastery: Own the user experience for complex, policy-laden workflows, ensuring multi-step wizards and data-dense interfaces are simple and intuitive.
    • Design System Leadership: Develop and maintain a React/TypeScript component library where accessibility (Section 508/WCAG) and plain-language labeling are built-in by default.
    • Rigorous Engineering: Maintain a high bar for production software through Test-Driven Development (TDD), automated CI scans, and Playwright end-to-end testing.
    • Continuous Shipping: Operate in an always-green main branch environment, shipping small, reviewable changes to stakeholders constantly.
    • Collaborative Innovation: Share knowledge through documentation, demos, and pairing to improve the team's engineering harness and AI rules.

Required Experience/Clearance

    • Clearance: Ability to obtain and maintain a US Secret security clearance.
    • 3+ years of experience building production web systems 
    • Technical Stack: Proficiency in TypeScript, React, Node.js, and PostgreSQL.
    • Agentic AI Literacy: Hands-on experience using AI development tools (Codex, Claude Code, or equivalent) on real-world codebases.
    • Ecosystem Fluency: Strong understanding of cloud infrastructure (AWS), CI/CD pipelines (GitHub Actions), and security fundamentals.

Desired Experience

    We encourage all candidates who meet the basic requirements to apply, even if you do not have any of the following experience:

    • Accessibility Depth: Expertise in WCAG/508 compliance and testing with assistive technologies.
    • Complex Tooling: Experience with document generation (PDF rendering) and complex form/wizard architectures.
    • Modernization: Prior experience migrating expert-user legacy "fat-client" applications to web platforms.
    • Regulated Environments: Experience working within government or highly regulated technical environments.
    • Infrastructure as Code: Familiarity with AWS CDK (TypeScript) and container orchestration (EKS/ECS).

The salary range provided for this position represents the anticipated base salary for successful candidates. Actual compensation will be determined based on a variety of factors, including relevant experience, education, certifications, skills, security clearance level, geographic location, market conditions, and internal equity. In addition to base salary, eligible employees may participate in Redhorse's comprehensive benefits programs and may be eligible for performance-based or other incentive compensation, where applicable.
