Leidos Defense 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.

Leidos’ Defense is seeking a Systems Engineer to join the IFPC Inc 2 systems engineering team. The IFPC Inc 2 is a ground-based, mobile system that aims to combat cruise missiles and unmanned aircraft systems. As part of the Indirect Fire Protection Capability program (IFPC), the system protects and defends civilian and military infrastructure and bridges the gap between tactical short range air defense systems and our strategic systems.

This Systems Engineer will be an administrator for the digital engineering tools within the systems engineering ecosystem. This systems engineer must have experience with developing systems engineering artifacts, including Requirements Specifications, Test Procedures, Test Reports, CONOPS, and Model-Based Systems Engineering (MBSE) content. This systems engineer must have experience with Cameo Systems Modeler, Jama, or another equivalent requirement management tool.

Specific roles and responsibilities include:

• Managing and improving metamodels based on systems engineering process

• Addressing tool issues

• Data management for requirements and architecture elements

• Managing SE workflows

• Managing user lists and user privileges

• Ability to perform technical systems engineering tasking such as requirements development and management, verification, and architecture modeling

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 program ends, 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 Model-Based Systems Engineering, Human Factors Engineering, Risk Management, and Reliability Analysis will be treated preferentially. However, a strong background in traditional systems engineering and technical leadership is what is required for this position.

Basic Qualifications

• Bachelor’s degree in Systems Engineering, Software Engineering, Computer Science, Computer Engineering, Electrical Engineering, Mechanical Engineering, Aerospace Engineering, or equivalent degree with 4+ years of experience or master’s degree in relevant field with 2+ years.

• 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.

• Possess a secret clearance, or have the ability to obtain a secret clearance.

Preferred Qualifications

• Master of Science in System Engineering

• Magic Draw and/or other Model Based System Engineering (MBSE) modeling tools

• Demonstrated experience effectively leading a team of engineers.

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

• DOORS and/or other requirements database tools

• 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)
