Original job description

Software Developer Leidos is seeking a Software Developer to support the rapid development of operations, data analysis, and data visualization applications in a dynamic mission environment. This is a fast-paced development environment where emerging operational needs often require quick, practical software solutions that can be deployed rapidly and refined over time.

The successful candidate will work closely with the customer and end users to understand evolving requirements, solve complex data-driven problems, and deliver effective solutions across both front-end and back-end environments. The role supports the full software development lifecycle, including requirements analysis, design and development, troubleshooting, deployment, system backup and recovery, and enhancement of both existing and new applications. This position is located in Chantilly, VA.

CLEARANCE REQUIREMENT: Candidates must currently possess an active TS/SCI clearance and be willing and able to undergo a polygraph. Candidates who do not currently possess an active TS/SCI will not be considered.

Primary Responsibilities

Design, develop, maintain, and enhance mission-critical software applications.
Rapidly develop and deliver software solutions in response to emerging operational needs and evolving requirements.
Develop both front-end and back-end components in support of operational and data-analysis requirements.
Work directly with customers and end users to gather requirements and translate operational needs into technical solutions.
Develop applications supporting the analysis and visualization of large and complex datasets, including geospatial data.
Troubleshoot and resolve complex software, system, and data-related issues.
Participate throughout the software development lifecycle, including requirements, design, development, testing, deployment, and sustainment.
Research and integrate new technologies as mission and technical requirements evolve.

Basic Qualifications

Bachelor's degree in Computer Science, Information Technology, or related technical field.
10+ years of relevant software development experience.
Current/active TS/SCI security clearance and willingness to undergo a polygraph.
Demonstrated experience rapidly developing and delivering software solutions in response to time-sensitive or evolving operational requirements.
Experience developing applications using an object-oriented programming language such as Java or C#/.NET.
Experience developing in Python.
Experience with modern JavaScript frameworks such as React.js, Node.js, or Next.js.
Experience with both relational and non-relational databases, such as MySQL and MongoDB.
Experience developing software that processes, analyzes, or visualizes large or complex datasets.
Experience with UI/UX design principles and translating user requirements into functional interfaces.
Experience developing in both Windows and Linux environments.
Experience with source-code repositories/version control, including Git and/or Subversion.

Preferred Qualifications

Experience working with geospatial datasets and developing applications supporting geospatial analysis or visualization.
Experience developing software in support of an operational mission environment.
Experience working with data formats including CSV, JSON, and XML.
Experience with containerization and orchestration technologies, including Docker and Kubernetes.
Experience with ActiveMQ.

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:

October 28, 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 $107,900.00 - $195,050.00 The Leidos pay range for this job level is a general guideline only and 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.
