Leidos Defense 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.

Leidos Defense is seeking a Systems Engineer to join a team developing an interceptor system. The Systems Engineer will join a matrixed organization of systems engineers, model-based systems engineers, and specialty systems engineers.

The Systems Engineer will use Cameo Systems Modeler and SysML to develop requirements specifications, system architecture content (bdd / ibd), and system behavioral content (act / stm). This position does not necessarily require an MBSE Subject Matter Expert, but the role does minimally require experience working independently on MBSE models, some model customization, and the ability to communicate with non-Systems Engineering stakeholders who are less familiar with MBSE approaches.

The Systems Engineer will work in a matrixed organization, which supports multiple programs at once in a variety of engineering fields with all different team environments. When the efforts end, the Systems Engineer will have the opportunity to support a different program in the matrixed engineering portfolio. A candidate with experience in other systems engineering areas such as Lead Systems Engineering, Human Factors Engineering, Risk Management, and Reliability Analysis will be treated preferentially. Success in this organization often leads to leadership positions in Model-Based Systems Engineering, Systems Engineering, and Systems Engineering Integration and Test (SEIT).

Basic Qualifications

• Bachelor’s degree in Systems Engineering, Software Engineering, Computer Science, Computer Engineering, Electrical Engineering, Mechanical Engineering, Aerospace Engineering, or equivalent degree from an ABET-accredited university.

• Experience using MagicDraw, Cameo Systems Modeler and/or other Model Based System Engineering (MBSE) modeling tools

• Experience in deriving requirements for complex electrical, electro-mechanical, mechanical, and software systems.

• Position requires candidates to be capable of performing in a collaborative engineering environment working closely with multi-disciplinary teams.

• Demonstrated experience effectively communicating within a team environment.

• Resident of the North Alabama area or willing to relocate to the Huntsville - North Alabama, AL area.

• Candidate must be a US Citizen and meet the eligibility to obtain (and maintain) a Secret Clearance

Preferred Qualifications

Preferred candidates will also have experience and/or working knowledge with:

• Demonstrated experience effectively leading a team of engineers.

• Demonstrated experience accurately estimating the engineering effort (i.e. hours) associated with Systems Engineering tasks.

• Understanding of the DoD acquisition processes and methods

• Experience supporting one or more DoD programs

• Object Management Group (OMG) Certified System Modeler Professional (OCSMP) certification

• INCOSE Systems Engineering Professional (SEP) certification (ASEP or CSEP)
