Remote Nodejs Developer Jobs in Longmont, CO (NOW HIRING)

Lynker, a Federal Government Contractor, is seeking to fill a full-time position for a Senior Full Stack Developer, to support a long term contract with the Space Weather Prediction Center (SWPC). Space Weather refers to variations in the space environment between the sun and Earth that can affect technologies in space and on Earth. Space weather is primarily driven by solar storm phenomena that include coronal mass ejections, solar flares, solar particle events and solar wind. These phenomena that are directed toward Earth are potential drivers of space weather events that can disrupt communications, satellite and airline operations, navigation and surveying systems, as well as electric power grids across large geographic regions on Earth. Space weather is a global issue and an understanding of solar storm phenomena is an important component to SWPC's success at developing accurate space weather forecasts (event onset, location, duration, and magnitude). 

The Senior Full Stack Developer supports SWPC by implementing intuitive, accessible, and responsive web interfaces that communicate critical space weather information. This position is a mid level to senior opportunity, ideal for individuals who want to contribute to the modernization of SWPC's web presence and Testbed applications.
