Entry Level Software Tester

About the role

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
