Job Description:

Parsons is seeking a talented Frontend Engineer to help develop next-generation, mission-critical applications for defense and national security missions. In this role, you will design and build responsive, intuitive user interfaces that help operators and decision-makers understand complex operational environments. You will work with large geospatial datasets, interactive two-dimensional and three-dimensional maps, real-time data streams, and situational awareness tools.

This is an opportunity to solve challenging frontend engineering problems while contributing to technology that supports critical missions.

What You'll Be Doing:

• Design frontend architecture: Help define and evolve the architecture of complex geospatial applications using React, TypeScript, and modern state management patterns.
• Build geospatial visualizations: Develop high-performance mapping and visualization components using technologies such as OpenLayers, CesiumJS, WebGL, or related frameworks.
• Work with large datasets: Create interfaces capable of displaying and interacting with substantial geospatial datasets, real-time feeds, and map layers.
• Optimize application performance: Profile and improve rendering performance, memory usage, network activity, and interaction latency, including on hardware-constrained systems.
• Develop data-intensive workflows: Use asynchronous programming, web workers, and efficient data-processing techniques to support demanding visualization and analysis workflows.
• Integrate secure services: Partner with backend and DevOps engineers to integrate APIs, cloud-native services, authentication mechanisms, and secure data pipelines.
• Collaborate across disciplines: Work closely with UX and UI designers, product owners, systems engineers, and end users to create effective and intuitive mission-focused experiences.
• Maintain engineering quality: Write maintainable, well-tested code; participate in design discussions and code reviews; and contribute to frontend standards and best practices.
• Support team growth: Mentor junior and mid-level engineers and help establish development practices that improve quality, consistency, and delivery.
• Contribute to technical direction: Evaluate tools and technologies, identify opportunities for improvement, and help guide the evolution of the application platform.

What Required Skills You'll Bring:

• Must be a U.S. Citizen.
• Bachelor's Degree Computer Science, Computer Engineering or related field and 5+ years of professional software engineering experience with a heavy emphasis on React and modern frontend ecosystem tools. Additional years of experience may be considered in lieu of a degree.
• Significant professional experience developing frontend applications with React and TypeScript.
• Strong knowledge of modern JavaScript, including ES6 and later, asynchronous programming, and contemporary frontend development practices.
• Experience designing and implementing reusable, maintainable user interface components.
• Experience working with geospatial data or mapping technologies, including one or more of the following:GeoJSONKMLRaster or vector tilesCoordinate reference systemsGeospatial APIsOpenLayers, CesiumJS, MapLibre, Mapbox, or comparable libraries
• Experience diagnosing and improving browser performance, including rendering, memory usage, network activity, and application responsiveness.
• Experience creating automated tests using tools such as Jest, Cypress, Playwright, or comparable frameworks.
• Strong communication and collaboration skills.
• Ability to work effectively in a mission-focused, highly collaborative engineering environment.

What Desired Skills You'll Bring:

• Active security clearance at the level required for the applicable program.
• Experience working on defense, intelligence, aerospace, or other national security applications.
• Experience deploying applications in secure or regulated cloud environments, including AWS GovCloud.
• Familiarity with Docker, Kubernetes, and cloud-native application deployment.
• Experience developing applications that support DoD cybersecurity or compliance requirements, including applicable Impact Level requirements.
• Experience with three-dimensional geospatial visualization using CesiumJS, Three.js, WebGL, or related technologies.
