Job description

Overview
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.

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. Working closely with the Web and Testbed teams as well as other developers in the Technology Division, the developer will translate scientific and operational requirements into clean, user-centered designs, and support front-end implementation using contemporary web technologies.

  • Deploy applications to dedicated servers using Docker

  • Lead a team of developers, providing technical direction and code/QA review
  • Meet regularly with clients and stakeholders to maintain open communication and align on project goals
  • Assess stakeholder needs and translate them into actionable requirements using Agile/Scrum methodology

Quality Assurance & Testing
  • Test and QA other developers' work as part of the standard development process
  • Write automated test scripts using Selenium and Playwright to validate new deployments and prevent regressions
  • Contribute to debugging and continuous improvement of application architecture

Product & Engagement Initiatives
