Job description

Looking for an opportunity to make an impact? 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 sustainable. Everything we do is built on a commitment to do the right thing for our customers, our people, and our community. Our Mission, Vision, and Values guide the way we do business. Are you ready for your next career challenge?

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 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 join a matrixed organization of systems engineers, model-based systems engineers, and specialty systems engineers. 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. 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.

• Develop and manage the IFPC verification process & strategy
• Stand up a verification review board
• Own system level DVOs and VCNs
• Review and approve all DVOs and VCNs at the subsystem and below level including software
• Present metrics and status to SE lead and leadership weekly
• Plan verification priorities and manage a verification burndown against multiple configurations
• Ensure requirements are verifiable
• Manage the linkages between verification artifacts and requirements such as test procedures and analysis results
• Work to define success criteria
• Work a path towards addressing verification gaps
• Own the system level VCRM
• Mentor team in writing good verification artifacts
• Manage verification artifacts against multiple system configurations

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 from an ABET-accredited university with 8+ years of experience or an MS with 6+ 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.
• US Citizenship is required with active secret clearance or ability to obtain and maintain a secret clearance.

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 2-4 years of direct systems engineering experience.
• MagicDraw 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)
