Help deliver the digital capabilities that connect the Intelligence Community with critical information, enable secure access to mission-essential services, and ensure users have reliable technology when it matters most.

Leidos is seeking an innovative, hands-on Senior Software Engineer to support the Chinook program supporting an Intelligence Community (IC) customer. This hybrid opportunity offers a combination of onsite collaboration and remote work, providing the flexibility to work independently while partnering closely with engineering teams and customer stakeholders to deliver impactful solutions. In this role, you'll help design, build, and enhance modern web and mobile applications that provide users with reliable access to information and services supporting security objectives.

This is a unique opportunity to combine hands-on full-stack software engineering with Agile team leadership. You'll develop modern, responsive user experiences using Next.js, React.js, JavaScript, and CSS, build scalable backend services using Python, Django, Wagtail, and PostgreSQL, and develop mobile applications using React and iOS technologies. You'll also leverage Amazon Web Services (AWS) to deliver secure, scalable, cloud-hosted solutions.

Beyond writing code, you'll help drive the team's success by facilitating Scrum ceremonies, supporting sprint execution, removing team-level impediments, and promoting continuous improvement. Working closely with developers, Product Owners, and customer stakeholders, you'll help ensure the team delivers high-quality software while maintaining a collaborative, mission-focused Agile environment.

If you're a skilled full-stack engineer who enjoys solving complex technical challenges, leading through collaboration, and seeing your code make a meaningful impact on security missions, we want you on our team.
