Systems Engineering Internship

Lyntrisis a defense technology company that connects sensing to action across the connected battlespace.

Lyntrisbrings together the talents of Accelintand Vitesse teams under one mission, with each contributing deepexpertisewithin their domain.

Combining differentiated hardware,software and mission expertise,Lyntrishelps 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 Forceand allied partners — spanning strategic,operational and 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.

We are seeking a motivated Systems Engineering Intern currently pursuing a master's degree in Human Factors, Systems Engineering, Human-Computer Interaction, or a related field. This position will support the development and evaluation of AI-enabled software products designed to solve complex problems for military and commercial users.

Working alongside experienced Systems Engineers, software developers, researchers, and product managers, the intern will assist with identifying user needs, developing and managing system requirements, and conducting software testing and evaluation. The ideal candidate has a strong interest in human-centered systems engineering, requirements elicitation, and translating user needs into functional software capabilities.

This internship provides hands‑on experience throughout the software development lifecycle, with opportunities to contribute to real‑world products and interact with multidisciplinary technical teams.
