Description Do you want to join a high performing team that values integrity, innovation, and collaboration with a company whose mission is to make the world safer, healthier, and more efficient through information technology, engineering, and science? Are you interested in making a difference by applying your signature production skills toward state-of-the-art research and development problems? Leidos currently has an exciting opening for a signatures modeling engineer to work in our Beavercreek office in the greater Dayton, OH area.
As a Signatures Modeling Engineer, you will apply your skills and critical thinking to a wide variety of signature modeling programs supporting AFRL, NASIC, LCMC, and other customer agencies. You will run state of the art signature prediction codes, like Xpatch and SENTRi on airborne and ground-based vehicle models to generate highly accurate signature models. You will also create custom signature prediction tools and perform special analyses in support of critical customer mission areas. This job offers a unique ability to collaborate directly with the creators of industry standard tools such as Xpatch as well as others (SENTRi, etc.). We are looking for a qualified candidate to bring technical excellence, leadership, entrepreneurship, and creativity to our programs. You will interact with customers, participate in, and lead technical projects areas, and pursue growth in new areas. This position requires most job duties to be performed onsite due to the sensitive nature of this work and the desire for in-person collaboration, however we offer flexible in-office hours and the ability to perform some job duties remotely.
