Job description

Lyntrisis a defense technology company that connects sensing to action across the connected battlespace.Lyntrisbrings together the talents ofAccelintand Vitesse teams under one mission, with each contributing deepexpertisewithin their domain.Combining differentiated hardware,softwareand missionexpertise,Lyntrishelps customers sense threats,make sense of complex conditions and act with greater speed,precisionand confidence in contested environments.

Lyntris supports U.S. and allied defense organizations across every branch — including Navy, Army, Air Force, SpaceForceand allied partners — spanning strategic,operationaland tactical missions and every domain: Space, Air, Land, Sea and Cyber. With more than 200 active defense programs,Lyntrisworks 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.Lyntrismoves 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.

Artificial Intelligence/Machine Learning (AI/ML) Engineer Interns will help develop applications that utilize AI technologies which adapt and scale to solve sophisticated problems across a variety of problem domains. Please note this is is a part-time internship position that starts in November/December 2026.
