Sr Mechanical Engineer

Leidos•Huntsville, AL

3d•$154,050 - $278,475

About The Position

Leidos Defense Systems is seeking a highly motivated Senior Mechanical Engineer to advance Value Driven Design and Model-Based Systems Engineering (MBSE) workflows across complex, high-priority Department of Defense portfolios. The role bridges systems architecture, parametric lifecycle modeling, and cross-functional engineering execution for missile systems and fieldable launch platforms. The engineer will lead the design and delivery of avionics, weapon interfaces, and custom or commercial off-the-shelf Line Replaceable Units (LRUs), contributing throughout development from planning and design through implementation, testing, and delivery. The position also involves leading multidisciplinary Integrated Product Teams, serving as an internal technical authority, and coordinating with external subcontractors and systems engineering teams. The role supports translation of military standards into hardware requirements and provides technical input for work breakdowns, schedules, Earned Value Management, capital expenditure initiatives, and competitive proposals. Candidates must be U.S. citizens and reside in or be willing to relocate to the Albuquerque, New Mexico, or Huntsville, Alabama, area.

Requirements

Bachelor’s degree in Mechanical Engineering or a related technical field.
10 or more years of relevant experience with a bachelor’s degree, or 8 or more years with a master’s degree, in mechanical engineering for complex aerospace, missile, or defense systems.
Demonstrated experience owning end-to-end systems engineering—including requirements, architecture, interfaces, integration, verification, and validation—on large or complex projects.
Experience with missile, high-speed flight, or advanced weapon systems, such as hypersonics, ballistic missiles, or interceptors.
Experience with requirements and configuration management tools such as DOORS or an equivalent; familiarity with MBSE concepts and tools.
Proven ability to lead cross-functional engineering teams and resolve complex technical issues.
Strong written and verbal communication skills, including experience briefing leadership and customers.
U.S. citizenship.
Must reside in or be willing to relocate to the Albuquerque, NM, or Huntsville, AL, area.
