Leidos' Defense is seeking a talented Model-Based Systems Engineer to join a diverse team to create unique solutions for complex problems. With offices across the United States engaging in the defense, space, cyber and commercial fields, Leidos provides responsive, cost-effective engineering, scientific and IT solutions.

The Model-Based Systems Engineer will work in a matrixed organization at Leidos, supporting multiple programs across a variety of engineering fields and team environment—from large-scale prime programs such as the Hypersonics Weapons Program and IFPC Inc 2 Program, to smaller-scale efforts where Leidos provides support as a subcontractor to top DoD contractors. The candidate will join a diverse team of systems engineers and have the opportunity to work on programs from their preferred background, as well as challenge themselves by working on programs outside of their expertise. A candidate with experience in other systems engineering areas such as General Systems Engineering, Human Factors Engineering, Risk Management, and Reliability Analysis will be treated preferentially. However, a strong background in Model-Based Systems Engineering is what is required for this position, and training opportunities for those other areas will be made available to the candidate while at Leidos.

Primary Responsibilities

The Model-Based Systems Engineer will develop a SysML Model using Cameo System Modeler that contains system architecture diagrams, system behavior diagrams, and requirements specifications derived from customer need. The selected candidate will interface with program management and design engineers to support a program’s systems engineering needs throughout its design life cycle, including modeling system behavior, defining the system architecture, dictating system interfaces, performing requirements verification, helping develop test programs, and maintaining configuration management. The selected candidate will perform verification audits against collected objective evidence for a compliance assessment. The selected candidate may present the systems engineering artifacts they have developed to the customer in formal design reviews and may serve as a customer liaison in many of their programs.

The Model-Based Systems Engineer will lead the modeling effort for a team of 5 Systems Engineers with varying levels of modeling experience who will also interface with the model under the MBSE’s guidance. The Model-Based Systems Engineer may be expected to support customer meetings by presenting technical material from the system model.

Basic Qualifications

• A 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 with 8+ years of experience or MS with 6+ years.
• Experience modeling in Cameo Systems Modeler (or equivalent) using SysML, and experience using Teamwork Cloud.
• 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.
• Demonstrated experience effectively leading a team of engineers.
• Ability to obtain and maintain a Secret clearance.
• Resident of the North Alabama area or willing to relocate to the Huntsville - North Alabama, AL area.

Preferred Qualifications

Preference shown to candidates who possess a Master of Science in System Engineering from an ABET-accredited university, and/or have at least 6-8 years of direct systems engineering experience.

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

• Other Model Based System Engineering (MBSE) modeling tools such as Sparx EA or IBM Rhapsody, using other modeling languages such as UML or the DoDAF Modeling Language (UPDM)
• DOORS and/or other requirements database tools
• Understanding of the DoD acquisition processes and methods
• Experience supporting DoD, NASA, or DARPA program
• Object Management Group (OMG) Certified System Modeler Professional (OCSMP) certification
• INCOSE Systems Engineering Professional (SEP) certification (ASEP or CSEP)
