About The Position

As a Frontend Engineer on the Forge Platform Applications team, you will build the core web experiences that autonomy developers use every day to design, test, evaluate, and ship mission level autonomy. You will create fast, reliable interfaces that visualize simulation data, observability streams, learning workflows, and analysis outputs. You will define frontend architecture, raise engineering standards, and contribute directly to backend and data layers when needed. The work is hands on: daily commits, complex feature delivery, and tight iteration with users. You will collaborate with product, design, autonomy, and backend teams to turn platform primitives into intuitive tools that accelerate autonomy development.

Requirements

• Typically requires a minimum of 15 years of related experience with a Bachelor’s degree; or 14 years and a Master’s degree; or a PhD with 12 years experience; or equivalent experience.
• Strong expertise in React, Typescript, and modern state management for large scale applications.
• Experience building data intensive, real time, or visualization heavy UIs.
• Experience profiling and optimizing frontend performance in data heavy or real time applications.
• Ability to translate Figma designs or loose product guidance into production quality interfaces.
• Working proficiency with Go or Python in support of frontend features.

Nice To Haves

• Exposure to autonomy, robotics, reinforcement learning, MLops, or large scale data analysis workflows.
• Familiarity with real time pipelines such as WebSockets, WebRTC, or streaming backends.
• Experience with WebGL, Three.js, geospatial rendering, or simulation oriented UIs.
• Background building SDKs, shared component libraries, or core application tooling that supports multiple teams.
• Experience with Docker, CI pipelines, Linux development, and cloud environments.
• Experience delivering software in constrained or secure environments, including air gapped systems.

Responsibilities

• Build high performance interfaces for simulation visualization, analysis tooling, observability, and workflow configuration.
• Lead frontend architecture, component systems, and UI patterns across Forge applications.
• Work with backend engineers to shape APIs and extend services in Go or Python to support new capabilities.
• Deliver user facing workflows that increase autonomy development velocity and reduce friction for expert and novice users.
• Improve reliability through testing, CI enhancements, documentation, and strong code review practices.
