World leader in creation and development.

At L3, we're pushing the boundaries of science with this in mind: you can't manage what you can't see. We gather data, visualize it, and make it usable in real time.

We've taken large communications systems–ground-based, mobile, satellite, surveillance and reconnaissance – and developed new ways to make them smaller and more capable. Some of the systems we build, used to be about the size of a small truck, now fit in the palm of your hand, not much bigger than a smart phone. But, instead of social media and texting friends, our smart devices send mission-critical data during armed conflicts to help our troops stay safe by staying in touch with key information. Our product connects hardware and software; ground-to-air and back; and people to people. We have developed better tools, smaller and more compact, doing bigger and bigger tasks with pinpoint accuracy.

"Until I came to work for L3 in 2001, I always worked at small companies with limited resources. I chose L3 because I wanted to learn from more experienced engineers. I found myself working alongside some of the best engineers in the industry, and I've learned so much!" – Systems Engineer

Software Engineer

"Over the last two years at L3, I've worked with our government customers on new technologies in electronic warfare and unmanned systems, replacing the human in the cockpit with software. I love creating complex systems and seeing them work. I also love solving hard problems with software, giving our country's military a very beneficial technological advantage. My career goal is to become be a senior software developer and architect. L3 gives me the opportunity to work with world-class people addressing world-changing challenges." – Software Engineer
