Job description

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.
We are seeking a Senior Systems Engineer to support systems and system-of-systems engineering efforts across complex technical environments. This role will be responsible for architecture design, integration, testing, implementation, certification activities, and technical analysis in support of mission and business objectives.
The ideal candidate is analytical, detail-oriented, and capable of working both independently and collaboratively in a fast-paced environment. This position requires strong problem-solving abilities, technical documentation experience, and the ability to interpret data and translate findings into actionable recommendations.
