About the Civil Aviation Team
We are modernizing America’s air traffic control system on an accelerated timeline, tackling one of the world’s most complex real-time optimization challenges: safely coordinating tens of thousands of daily flights in a dynamic, safety-critical environment. Our team is building next-generation trajectory prediction and decision-support systems while preparing the airspace for emerging technologies like commercial space operations and advanced air mobility. This mission-critical work demands exceptional precision, resilience, and reliability to support the safety and efficiency of the national airspace.
What You Will Do:
As part of our product engineering team, you'll work closely with our civil aviation and design teams to create mission-critical products with a top-notch user experience. You'll work on systems that reflect the real-world intricacies of air operations and build new user-facing features in React, Redux, Mapbox, and TypeScript, with everything from database models to APIs.
What We Value:
- Proficiency in JavaScript/TypeScript, React, and CSS.
- Experience building complex, map-based web applications with Mapbox, Maplibre, or Google Maps, with a focus on real-time rendering of multiple interactive features and overlays.
- Familiarity with WebGL, WebGPU, or ThreeJS for accelerated graphics rendering and WebAssembly (WASM) for enhancing application performance.
- A bias for action. When you see a problem, you solve it.
- Ability to write fast, efficient, and maintainable code.
- Strong attention to detail and a passion for great user experiences.
- Proficient in leveraging modern LLM tools to accelerate development workflows and enhance code quality.
