Profile match
Leidos is an American technology and engineering services company created in 2013 when Science Applications International Corporation split in two, with Leidos taking the technical services and solutions business. It is one of the largest suppliers to the United States government, working across defence programmes, intelligence systems, civil agencies including the Federal Aviation Administration, and healthcare services for the Department of Veterans Affairs. Headquartered in Reston, Virginia, the company also builds security detection products for airports and borders, and has concentrated recent investment on trusted artificial intelligence and autonomy for mission environments.

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 a team of systems engineers developing a radar system. This Systems Engineer will have the opportunity to travel to customer sites and subcontractor sites (approximately 10% of the time). This Systems Engineer will develop systems engineering artifacts, including Requirements Specifications, Test Procedures, and Test Reports.

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 radar 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 engineering areas such as Test, Model-Based Systems Engineering, Human Factors, 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 5+ years of experience or an MS with 3+ years.

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

  • Experience in developing and executing system and sub-system verification activities.

  • 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.

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.

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

  • Demonstrated experience effectively leading a team of engineers.

  • Demonstrated experience communicating with customer representatives during engineering development and fielding efforts.

  • 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

  • Experience in formal testing for requirement V&V, particularly with radar program(s)

  • Familiarity with radar test/analysis tools including DRFM technology and MATLAB

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

  • Jama and/or other requirements database tools

If you're looking for comfort, keep scrolling. At Leidos, we outthink, outbuild, and outpace the status quo - because the mission demands it. We're not hiring followers. We're recruiting the ones who disrupt, provoke, and refuse to fail. Step 10 is ancient history. We're already at step 30 - and moving faster than anyone else dares.
