What are the responsibilities and job description for the Senior Software Engineer - Developer Experience & Code Quality position at Leidos?
In the Homeland Sector, our software helps protect communities and keep important systems running safely. As we build more software, we need to make sure it stays efficient, reliable, and easy to improve over time.
Must live in the Reston area and be able to commute to the Leidos GHQ office. Flexible to work remote with the ability to commute to the corporate office as needed.
This role plays a key part in that.
You'll improve how software is built across the sector-making code simpler, reducing duplication, and helping teams follow better practices. You'll track things like how much code we have, how complex it is, and how well it's tested, then use that information to help teams improve.
You'll also focus on making life better for developers by introducing modern tools and ways of working so teams can build software more easily and quickly.
This is a chance to make a big impact by improving how software is built across many projects that support important, real-world missions.
Primary Responsibilities:
Drive software reuse and refactoring across the sector to reduce duplication and improve code quality
Establish and maintain software baselines and visibility into code assets across programs
Define and analyze engineering metrics (e.g., code coverage, complexity, language composition) to guide improvements
Improve the developer experience through better tools, workflows, and practices
Partner with teams to standardize and modernize software approaches across programs
Evaluate and introduce new technologies and approaches, scaling what works
Basic Qualifications:
Bachelor's degree in Computer Science, Software Engineering, or a related field with 8 years of relevant experience. Additional years experience may be used in lieu of a degree.
Strong experience developing software in one or more modern languages (e.g., Java, Python, C , JavaScript) Experience improving code quality through refactoring, testing, and reducing technical debt
Familiarity with software metrics and analysis tools (e.g., code coverage, complexity, static analysis)
Must live in the Reston area and be able to commute to the Leidos GHQ office. Flexible to work remote with the ability to commute to the corporate office as needed.
U.S. citizenship and ability to obtain and maintain a security clearance
Preferred Qualifications:
Experience leading or contributing to enterprise-wide code reuse, standardization, or modernization initiatives
Familiarity with developer experience (DevEx) improvements, including tooling, workflows, and platform engineering concepts
Hands-on experience with static analysis, code quality, and security scanning tools (e.g., SonarQube, Fortify, Checkmarx)
Experience working in cloud environments (e.g., AWS, Azure, Google Cloud) and containerized architectures (e.g., Docker, Kubernetes) Knowledge of multiple programming languages and ability to work across diverse tech stacks
Experience establishing or managing software baselines, inventories, or asset catalogs
Familiarity with open-source frameworks and strategies for evaluating and adopting new technologies
Experience collecting and visualizing engineering metrics (e.g., dashboards, reporting tools)
Background supporting federal or homeland security missions
Active security clearance
