Original job description

Description

Leidos is seeking a Software Tester to work with the CEMA (Cyber and Electromagnetic Activities) department.

All products need proper testing; there is no question. Our products are responsible for alerting our varied array of customers of potential Cyber and EW attacks by creative adversaries highly skilled at attacking. With that problem set in mind, our products need to be tested by equally creative minds that enjoy digging, automating, and generally learning all they can do to do those exact things the threat actors would.

Our CEMA team is comprised of both red and blue: hackers, programmers, mathematicians, quantum scientists, data scientists, even a physicist, so knowledge is easily gleaned in our team for those willing to ask. Problem solving, troubleshooting, and a desire to break things for good reasons will be our focus for consideration.

Primary Responsibilities:

Performing test planning, monitoring, and execution.
Learning, troubleshooting, and asking lots of questions.
Developing and executing software test cases in a Linux/Windows environment with significant focus on repeatability.
Reviewing and verifying system level and software level requirements while working with team members to better understand them.
Discovering and documenting technical defects so team members can easily reproduce the issue.

Basic Qualifications:

Bachelor’s degree in one of the following: Cyber Security, Computer Science, Computer Engineering, Electrical Engineering, or related Technical Degree.
Experience in C++ or other high level SW languages
A proven ability to program (examples proved in GitHub, prints out, or code by hand in the interview).
Navigational knowledge of Linux and Windows.
Problem solving skills (imagine a hundred exclamation points behind this qualification).
Candidate must be a US Citizen and possess (and be able to maintain) a Final Top Secret/SCI clearance or meet the eligibility to obtain (and maintain) a Top Secret/SCI clearance.

Preferred Qualifications:

Experience or Working Knowledge of C++, Python
Experience or Working Knowledge in Jenkins and Groovy scripting
Bash/PowerShell scripting
Familiarity with Jira - issue tracking and agile project management, or similar tool
Experience or Working Knowledge of writing automated and/or unit tests

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.

Original Posting:

November 5, 2026

For U.S. Positions: While subject to change based on business needs, Leidos reasonably anticipates that this job requisition will remain open for at least 3 days with an anticipated close date of no earlier than 3 days after the original posting date as listed above.

Pay Range:

Pay Range $50,700.00 - $91,650.00

The Leidos pay range for this job level is a general guideline onlyand not a guarantee of compensation or salary. Additional factors considered in extending an offer include (but are not limited to) responsibilities of the job, education, experience, knowledge, skills, and abilities, as well as internal equity, alignment with market data, applicable bargaining agreement (if any), or other law.

Securing Your Data

Beware of fake employment opportunities using Leidos’ name. Leidos will never ask you to provide payment-related information during any part of the employment application process (i.e., ask you for money), nor will Leidos ever advance money as part of the hiring process (i.e., send you a check or money order before doing any work). Further, Leidos will only communicate with you through emails that are generated by the Leidos.com automated system – never from free commercial services (e.g., Gmail, Yahoo, Hotmail) or via WhatsApp, Telegram, etc. If you received an email purporting to be from Leidos that asks for payment-related information or any other personal information (e.g., about you or your previous employer), and you are concerned about its legitimacy, please make us aware immediately by emailing us at LeidosCareersFraud@leidos.com .

If you believe you are the victim of a scam, contact your local law enforcement and report the incident to the U.S. Federal Trade Commission (https://reportfraud.ftc.gov/#/) .
