Job Title: Lead, Software Systems Engineer

Location: Plano, TX

Job Description:

Let's start with who we are: Advanced Systems & Technologies (AS&T) division specializes in developing disruptive, next-generation technologies for advanced radar systems, next-generation weapon systems, and other RF sensor technologies. What does that mean? It means that as the non-traditional 6th prime, we're developing entirely new clean sheet designs. We aren't designing upgraded parts of an existing system. We are immersed in technology and we are technology driven. Model Based Systems Engineering is part of our systems engineering DNA.

What's a day in the life like in this role? This is a lead software systems engineering position, so the tasking is like what you've done before. But the difference is that you're working in a completely different culture and mission mindset. Our team sizes are smaller, allowing for collaboration, great ideas, and contribution from all levels in an agile product development environment. In other words, you're not stove-piped into one area, and instead can work the entire engineering lifecycle. You get to solve hard problems. Your day is spent working on new and exciting technology and methodology that hasn't been done before. You're inspired to do your best work every day, because what we do matters!
