About ASI

ASI is the frontier AI company that dynamically orchestrates critical infrastructure and defense assets, across air traffic control, energy, logistics, and combat operations. ASI's systems simulate physical operations, hours, days, and weeks ahead, so the people running air traffic control, the electric grid, and military operations can catch problems early and act before they spread. ASI is powering vital infrastructure for customers like United Airlines, National Grid, the Federal Aviation Administration, Delta Air Lines and the Department of War. ASI is headquartered in Boston with offices in Washington, DC, Denver, and Europe, and is backed by leading investors, including Andreessen Horowitz, Citadel Securities, and Spark Capital.

What you will do

As part of our energy engineering team, you’ll work closely with our energy and design teams to create mission-critical products for utilities and grid operators, with a top-notch user experience. You’ll work on systems that reflect the real-world complexity of the power grid, such as energy storage siting, interconnection planning, and grid resilience, 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 writing 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.
