Application Engineer

From autonomous uncrewed defense systems to next-generation avionics and integrated battle management systems, RTI’s software powers the world’s most demanding real-time platforms. We are looking for an engineer who thrives at the intersection of distributed architecture, deep-dive systems debugging, and direct customer engagement.

As a key member of our Professional Services team, you will act as a trusted technical advisor to leading Aerospace & Defense engineering teams. You will tackle complex distributed systems challenges, optimize microsecond-level deterministic data flows, and ensure mission-critical software performs reliably when failure is not an option.
