Software Engineer II

company

Lyntris   is a defense technology company that connects sensing to action across the connected battlespace.   Lyntris   brings together the talents of   Accelint   and Vitesse teams under one mission, with each contributing deep   expertise   within their domain.   Combining differentiated hardware,   software   and mission   expertise, Lyntris helps customers sense threats, make sense of complex conditions and act with greater speed,   precision   and confidence in contested environments.

Lyntris supports U.S. and allied defense organizations across every branch — including Navy, Army, Air Force, Space   Force   and allied partners — spanning strategic,   operational   and tactical missions and every domain: Space, Air, Land, Sea and Cyber. With more than 200 active defense programs,   Lyntris   works at every level of the mission, from national command authority to the tactical edge.

Solutions are designed by operators who understand the mission, engineered for the conditions that degrade or defeat standard systems, and built on an open, modular architecture that integrates into existing programs without requiring them to start over.   Lyntris   moves faster than the traditional defense cycle — with integrated design, build and test capabilities in-house — and delivers systems that sustain and endure long after initial fielding.
