Senior Software Engineer

A specialist systems and security engineering organization is seeking software engineers to build mission-critical capabilities for direct U.S. Government customers, including the NSA.

This is an opportunity to use the full value of an active TS/SCI with Full Scope Polygraph while working directly alongside government users and technical stakeholders. Engineers are trusted with genuine autonomy, technical authority, and visibility across the mission rather than being limited to narrowly defined development tasks.

You will have the freedom to influence architecture, select technical approaches, solve complex engineering problems, and take ownership from initial requirements through deployment and operational support. The environment suits engineers who want their judgement to carry weight and their work to have a clear, measurable mission impact.

Software engineers in this role design, develop, integrate, test, deploy, and maintain complex software systems supporting national security missions.

Engineers work directly with government customers, users, software engineers, and systems engineers to understand operational requirements and turn them into practical technical solutions. You will have authority over key engineering decisions, contribute to system architecture and technical roadmaps, and own solutions throughout the full software development lifecycle.

Additional responsibilities include developing high-performance software, processing large datasets, integrating system components, producing technical documentation, participating in peer reviews, supporting automated testing and deployment, and resolving change requests or defects within operational systems.

• Strong programming experience in C or C++
• Experience developing software with Python
• Software development in Linux or UNIX environments
• Experience designing, developing, integrating, and testing complex software systems
• Ability to translate mission requirements into scalable technical solutions
• Experience working across the full software development lifecycle
• Version control using Git
• Active TS/SCI with Full Scope Polygraph security clearance

• Software architecture and technical design
• Development of distributed or high-performance systems
• Large-scale data processing and performance optimization
• Automated testing and quality assurance
• Continuous Integration and Continuous Deployment pipelines
• Dev Ops tools and engineering practices
• CI/CD platforms including Jenkins, Bamboo, or Git Lab
• Elasticsearch or similar search and analytics technologies
• Front-end or web application development
• Windows and Linux or UNIX multi-platform development
• Technical leadership or mentoring experience
• Systems engineering, security engineering, or cybersecurity experience
• Experience supporting Intelligence Community or Department of Defense missions
• Qualifications
• Must be a U.S. citizen
• Must hold an active TS/SCI security clearance with Full Scope Polygraph
• Must be able to work onsite in Hanover, Maryland and directly support sensitive government missions, including NSA programs
