The selected candidate will be required to work on-site, full-time at our Melbourne, FL location. We are seeking a first-principles thinker and skilled data scientist to solve complex data challenges. This is not a role for operating pre-built tools; this is an opportunity to architect and build the core data logic of our systems. You will be responsible for creating custom, high-performance statistics and machine learning tools from the ground up, making meaning of complex data sets. Your work will involve deep data modeling, abstracting reusable patterns, and writing modular, maintainable code that stands the test of time. Note: Due to the classified nature of the work being performed, this position does not offer any virtual or telecommute working options. Applicants are encouraged to apply, only if they are willing to work on-site. The responsibilities of this role include, but are not limited to, the following: * Collaborate closely with software engineers, analysts, and other data scientists to understand data requirements and deliver robust, integrated solutions. * Architect and develop custom, maintainable data science solutions from the ground up. * Write and maintain tests and documentation for data architecture, workflows, and processes. * Champion software engineering best practices within the data domain, including comprehensive unit/integration testing, CI/CD automation (Git, Docker), and robust documentation. * Tune and optimize complex algorithms within our on-premise infrastructure. * Create and implement cutting-edge technologies powered by Artificial Intelligence (AI)., We offer flexible work arrangements, phenomenal learning opportunities, exposure to a wide variety of projects and customers, and a very friendly team environment. At Northrop Grumman, we are on the cutting edge of innovation. Our diverse portfolio of programs means there are endless paths to cultivate your career. We also offer exceptional benefits/healthcare, a 9/80 work schedule, and a great 401k matching program.
