If you want the opportunity to work with a small team of very talented developers on cutting-edge projects - we want to talk to you. We're a focused Scrum shop with a strong emphasis on self-managed teams. Our engineering teams value collaboration and hold the team in high regard. We will foster your career development and allow you to be creative in a fun; results based environment. You’ll work on the team that provides the weather data powering many products used by insurance companies across the United States. This data comes from many different sources and formats, and the business needs are constantly evolving.

Successful candidates will have a mastery of server-side concurrent programming on the JVM, and experience in GIS or Weather data sets/systems.
