We are looking for an experienced Computer Systems Engineer – React Developer with Pega Expereince to join the National Airspace System (NAS) Integration Support Contract (NISC IV) to support the Federal Aviation Administration in the Washington DC Office. As a Computer Systems Engineer – React Developer with Pega experience, you will play a crucial part in designing, developing, and maintaining high-quality software solutions as well as operational support to the program.

The React Developer will be responsible for designing, developing, and implementing user interfaces for web applications, with a focus on integrating these interfaces with Pega-based business process management (BPM) solutions. This role requires a strong understanding of both React.js for front-end development and the Pega Platform for back-end process and data management.

Responsibilities :

• Design, develop, and maintain responsive and interactive user interfaces using React.js and related technologies.
• Collaborate with business analysts and Pega developers to translate business requirements into technical specifications and implement front-end solutions that seamlessly integrate with Pega applications.
• Leverage React to build modern, custom front-end interfaces that integrate with Pega-based applications. This role combines strong front-end development skills with deep knowledge of the Pega platform's integration capabilities.
• Develop and integrate custom components and UI elements within the Pega UI framework, ensuring adherence to best practices and design standards.
• Work with Pega developers to define and implement integrations between React front-ends and Pega services (e.g., REST APIs, data pages).
• Optimize front-end applications for performance, scalability, and accessibility across various devices and browsers.
• Participate in the full software development lifecycle, including requirements gathering, design, development, testing, deployment, and support.
• Troubleshoot, debug, and resolve issues related to both React and Pega integrations.

Preferred Qualifications :

At Leidos, we don’t want someone who "fits the mold"—we want someone who melts it down and builds something better. This is a role for the restless, the over-caffeinated, the ones who ask, “what’s next?” before the dust settles on “what’s now.”

If you’re already scheming step 20 while everyone else is still debating step 2… good. You’ll fit right in.
