Full-stack React Developer


We are looking for a creative, motivated developer who is comfortable working in a modern, full web application stack and has particularly strong React skills.  On our team, you’ll own features throughout the software development lifecycle - from planning and implementing server-hosted APIs to designing and building front-end interfaces. You’ll need to be able to think independently and operate with a high degree of autonomy, while also participating in a welcoming community of passionate developers. We have challenges ranging from creating new ways to visualize medical information to implementing data pipelines to improving application performance. You’ll need to have a love for problem-solving, a passion for collaboration, and a can-do attitude.

SemanticBits is a leading company specializing in the design and development of digital health services, and the work we do is just as unique as the culture we’ve created. We develop cutting-edge solutions to complex problems for commercial, academic, and government organizations. The systems we develop are used in finding cures for deadly diseases, improving the quality of healthcare delivered to millions of people, and revolutionizing the healthcare industry on a nationwide scale. There is a meaningful connection between our work and the real people who benefit from it; and, as such, we create an environment in which new ideas and innovative strategies are encouraged. We are an established company with the mindset of a startup. We feel confident that we offer an employment experience unlike any other and that we set our employees up for professional success every day.
