Systems Engineering, Design & Development

At Leidos, we deliver innovative solutions through the efforts of our diverse and talented people who are dedicated to our customers’ success. We empower our teams, contribute to our communities, and operate sustainably. Everything we do is built on a commitment to do the right thing for our customers, our people, and our community. Leidos’ Defense Systems Advanced Development Organization is seeking an entry‑level to early‑career Systems Engineer specializing in Value ‑ Driven Design (VDD), Model ‑ Based Systems Engineering (MBSE), and parametric lifecycle modeling to support a classified, high‑speed system portfolio. The successful candidate will apply digital engineering frameworks to capture stakeholder requirements and translate mission‑critical engineering parameters into structured architecture baselines that feed decision‑quality trade studies.
Our team is a small advanced development group focused on hypersonic mission engineering , representing military utility, modeling lifecycle impacts of design decisions, and facilitating complex conceptual, system, and detailed design choices. Day‑to‑day activities include hands ‑ on MBSE modeling, requirements drafting, and trade study support , collaborative work inside a SCIF with cross‑functional engineering teams, and operating in a fast ‑ paced digital engineering environment with frequent technical writing, modeling, and analysis tasks. Occasional travel will be required for in‑person engagements with internal customers and suppliers across multiple Leidos sites.
Leidos Defense Systems Sector provides a diverse portfolio of systems, solutions, and services covering land, sea, air, space, and cyberspace for customers worldwide. Solutions for Defense include enterprise and mission IT, large-scale intelligence systems, command and control, geospatial and data analytics, cybersecurity, logistics, training, and intelligence analysis and operations support. Our team is solving the world’s toughest security challenges for customers with “can’t fail” missions. Draft and maintain EARS‑formatted requirement statements and attributes; document allocations of performance, cost, reliability, and verification to physical elements.
