About Leidos
Leidos is a FORTUNE 500® company bringing a mix of innovative technology and sector expertise to customers in the national security, engineering, and health industries. We deliver innovative solutions through the efforts of our diverse and talented people who are dedicated to our customers' success.
The Leidos Intel Sector combines technology-enabled services and mission software capabilities to support Intelligence Community customers as they address evolving national security challenges.
About the Opportunity
Leidos is seeking a Junior Software Engineer to join a team developing, maintaining, and enhancing software systems supporting critical mission needs.
This is an opportunity for an early-career software engineer to contribute to real-world software development while working individually and as part of an engineering team. You'll analyze requirements, design and modify software, debug defects, integrate software into operating environments, and help test software components against documented requirements.
No demonstrated professional software engineering experience is required for this position.
Why This Role Matters
Mission software must continue to evolve as requirements, technologies, and operational needs change. As a Junior Software Engineer, you'll contribute directly to the development and improvement of software capabilities while building experience across the software engineering lifecycle.
What You'll Do
Software Development & Integration
  • Analyze user requirements to derive software design and performance requirements.
  • Design and code new software or modify existing software to add new features.
  • Debug existing software and correct defects.
  • Integrate existing software into new or modified systems and operating environments.
  • Develop simple data queries for existing or proposed databases and data repositories.

Software Quality & Engineering Practices
  • Review and test software components for adherence to design requirements and document test results.
  • Help resolve software problem reports.
  • Apply software development and design methodologies appropriate to the development environment.
  • Provide recommendations for improving documentation and software development process standards.
  • Contribute to software-related system design considerations, including hardware/software tradeoffs, software reuse, COTS/GOTS alternatives, and requirements analysis from the system level to individual software components.

This posting is for multiple opportunities
Required Qualifications
Clearance
  • TS/SCI with Polygraph required upon Application, to be considered for this position.

Education & Experience
Candidates may qualify through either of the following paths:
  • Bachelor's degree in Computer Science or a related discipline from an accredited college or university. No demonstrated software engineering experience is required.

OR
  • Four (4) years of Software Engineering experience on projects using similar software processes may be substituted for the bachelor's degree.

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:
August 26, 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.
