Senior Back End Software Developer Security Clearance

Position: Senior Back End Software Developer with Security Clearance
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. nou Systems, Inc. (nSI) is 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 an opening for a Senior Back End Software Developer who will join our Technical Solutions Division and JSTC2 Team in Huntsville, Alabama to build software that provides war fighting training exercise participants unparalleled access to information about the unfolding scenario. You'll be part of a team that is not only modernizing the interface to the underlying war fighting simulations but also finding new and innovative ways of surfacing deep information about the scenario, providing end users the right information right when they need it.

Responsibilities:
Our small team is developing Government Off-the-Shelf software that is currently in use in ongoing war fighting exercises. We're seeking developers who can accelerate our progress along our years-long product roadmap. You'll be an integral part of a multidisciplinary software team combining a web-based front end, large-data-management back end, and on-prem LLM-powered data exploration. We're looking for developers who still enjoy coding while taking advantage of newer agentic coding approaches, and who want to help junior developers level up their skills through mentoring and focused code reviews.

We need people who enjoy working in tandem with other talented developers, architects, QA, and integration/Dev Ops, and who rise to the challenge of team communication and cohesion in an Agile/SAFe team. We want people who are passionate about the quality of software we deliver. You'll need to be comfortable with developing software that's delivered to end users on a 10-week cadence, helping elicit end user needs rather than being handed a pile of DOORS-managed requirements, and scoping work even in the absence of perfect information.
