Consider Joining Our Growing Team

Senior Front End Engineer

Green River is adding to our team of developers working in React and Ruby on Rails to create beautiful and performant applications for the web. We seek candidates committed to public health, school improvement, environmental protection, and social justice. As the climate changes, the population increases, and critical resource thresholds are breached, data and information systems will play an increasingly important role in defining and delivering solutions—for both economic benefit and human and ecological health. This vision drives us at Green River.

Incorporated in 2000, Green River is a custom web application development firm with a strong engineering focus and dedication to “software and analytics for a better world.” Our model requires software skills, analytical experience, business sophistication, and a genuine commitment to ethics and social responsibility. Our projects offer challenges in developing complex, scalable algorithms and well-designed responsive user interfaces. We regularly evolve our approach to software development as new best practices emerge. 

Our company enjoys a collaborative atmosphere and values a workplace where you can learn and laugh—together we shape the kind of work and lifestyle we want and foster career paths through mentorship. This has resulted in exceptionally long-term relationships with both our clients and our staff. Our primary offices are in scenic Brattleboro, Vermont, and we have distributed staff living and working around the country. Our current clients include Starbucks, the Commonwealth of Massachusetts, the City of Boston, the State of Delaware, World Resources Institute, Reach Out and Read, and many other domestic and international non-profit organizations. We believe in our clients’ work, and are committed to being good partners in their success.

The Senior Front End Developer will work in small teams with our clients, UI/Interaction designers, and back-end developers. While we have dedicated UX /UI designers, Green River produces our best work with design input from the whole team.
