Senior Software Developer

nou Systems, Inc. (nSI) is now officially a 100% ESOP company! We value teamwork and collaboration, and this transition allows us to take that commitment to a new level. nSI empowers our customers by supplying products, services, and expertise with powerful, data-driven insights that transform defense systems and improve capabilities. We’re building systems that solve our nation's most challenging defense problems in an enjoyable, stimulating environment. We’re known for fielding revolutionary missile defense systems, pioneering step changes in RF seeker technology, introducing principled AI systems, and rapidly pioneering novel defense platforms, from space to the seabed.

We're looking for talented builders with high levels of curiosity and extremely strong grounding in fundamentals and engineering first principles. If you're hungry for harder problems and want to build products that actually get into users’ hands, we’ve got you covered. We are pleased to announce openings for Senior Software Developers (front end, back end, and full stack) who will join our Technical Solutions Division and JSTC2 Team in Huntsville, Alabama to build software that provides warfighting training exercise participants unparalleled access to information about the unfolding scenario.

Skills

• Mentor and lead technical contributors to act as a force multiplier.
• Support software architecture development in collaboration with the Chief Architect.
• Strong communication and collaboration skills, including justifying technical decisions with quantitative information.
