The Challenge

Are you looking for an opportunity to not just develop software, but to build a system that will have a positive impact?  As a full-stack developer, you can solve a problem with a complete end-to-end solution in a fast-paced, agile environment. We’re looking for a developer with the advanced skills needed to build, test, and deploy applications, enhancements or microservices for existing applications on their own utilizing Test Driven Development (TDD), Lean, and XP methodologies from vision to production-ready systems.

This role is more than just coding. We need a full-stack developer who will use their passion to learn new tools and techniques, identify and implement system improvements, and mentor teammates. Using Ruby on Rails, ReactJS, or React Native and related technologies, you’ll build large Ruby on Rails Web applications and bleeding edge React Native mobile applications with RoR backends. You’ll analyze the needs and the environment to make sure the solution you’re developing considers the current architecture and operating environment and future functionality and enhancements. Join us as we build systems to change homeland security and immigration for the better.

Empower change with us.
