9d•Remote

About The Position

Agile Six is a people-first, remote-work company that serves shoulder-to-shoulder with federal agencies to find innovative, human-centered solutions. We build better by putting people first. We are animated by our core values of Purpose, Wholeness, Trust, Self-Management and Inclusion. We deliver our solutions in autonomous teams of self-managed professionals (no managers here!) who genuinely care about each other and the work. We know that’s our company’s purpose – and that we can only achieve it by supporting a culture where people feel valued, self-managed, and love to come to work. The Role Agile Six is looking for a Fullstack Engineer (Ruby/React) to join a cross-functional team working with the Department of Veterans Affairs on an integrated patient portal experience on VA.gov. The goal of our team’s work is to improve Veterans’ digital experience by giving them one place to easily manage their VA health care, community care, disability benefits, and other information. This role will serve as an individual contributor and be assigned to a designated product, potentially supporting development on adjacent product teams within the project. Fullstack engineers partner closely with the team's Engineering Lead to implement standards and best practices, and work closely with team members to support the development of a cohesive user experience across web and mobile platforms. We expect the responsibilities of this position to shift and grow organically over time, in response to considerations such as the team’s needs and strengths, the unique strengths and interests of the selected candidate, and an evolving understanding of the delivery environment.

Requirements

5 + years of professional engineering experience, demonstrating in‑depth knowledge in at least one front end and one back end technology stack (e.g. Ruby and React).
3 + years of recent production experience with React and JavaScript/TypeScript
1+ year of production experience with Ruby on Rails
Ability to leverage AI-assisted development tools (for this project, CoPilot specifically) to responsibly to accelerate delivery, improve code quality, and support experimentation per evolving client AI tooling expectations
Hands‑on experience with CI/CD pipelines, automated testing, and cloud infrastructure (AWS, Docker, Kubernetes, or similar).
Experience with measurement and monitoring tools (e.g., Datadog) and a strong understanding of application observability.
Familiarity with secure development best practices and Zero Trust principles; ability to safeguard sensitive data while working in an open‑source environment.

Nice To Haves

Bachelor’s degree in Computer Science, Engineering, or a related field (or equivalent practical experience).
Experience with React Native
Experience leveraging AI tools and services to create and deliver software to production in a professional capacity.
Experience with health-related services and Fast Healthcare Interoperability Resources (FHIR) standards.
Professional experience delivering software for or within federal agencies, especially the VA.

Responsibilities

Build accessible, performant, and scalable frontend and backend features in an open-source ecosystem using Ruby on Rails and other industry-standard languages and frameworks.
Develop user-facing features with React (TypeScript/JavaScript), following USWDS design patterns and VA API/FHIR standards where applicable.
Write and maintain 100% automated test coverage (unit, integration, functional, load, and accessibility) for all delivered features.
Integrate with VA APIs and backend services to ensure accurate, secure data rendering and discoverability via the Lighthouse API Hub.
Support the migration and retirement of legacy systems, ensuring continuity of content and functionality.
Contribute to full-stack development across healthcare features (e.g., secure messaging, medical records, medications) with a focus on interoperability and user-centered design.
Monitor and triage application performance issues daily using tools like Datadog, and respond to incidents according to VA-defined severity levels.
Prevent and resolve silent failures through robust error handling, user notification mechanisms, and backend transaction validation.
Participate in pair programming, peer reviews, and blameless post-mortems, incorporating learnings and promoting engineering excellence.
Continuously integrate and deploy code using VA Platform tooling, CI/CD pipelines, and reusable infrastructure components across VA.gov and VA Mobile.
Uphold Zero Trust security principles and ensure sensitive data is never exposed in source code; deliver all non-sensitive code to open-source repositories.
Support the Engineering Community of Practice and broader Agile Six engineering culture through knowledge‑sharing, mentoring, and participation in internal initiatives.
