AI is reshaping every function across our business, and we enable every team member, regardless of role or level, to build fluency in AI tools and concepts. Those who thrive here actively seek out new solutions, experiment thoughtfully, and apply what they learn to drive better, faster, smarter outcomes.

Own the roadmap and evolution of the shared component library and common frontend infrastructure

Set the technical direction for frontend engineering practices, tooling, and patterns across the organization

Partner cross-functionally with design systems, backend platform, and product teams to translate complex business requirements into robust technical implementations

Mentor and uplevel senior engineers through code reviews, design reviews, and hands-on collaboration

Integrate frontend experiences with REST APIs and backend services, including data-dense security dashboards, real-time telemetry feeds, and large-scale grid and table performance

Improve and maintain existing systems while continuously introducing better patterns, tooling, and technologies from the frontend ecosystem

What Skills and Knowledge Should You Bring?

Ideal candidates will have:

Strong hands-on experience in frontend development with a track record of building production-grade web applications at scale

Deep understanding of JavaScript, including the DOM, the JavaScript object model, and modern ECMAScript features

Strong proficiency with React and a thorough understanding of its core principles

Strong experience with TypeScript, component-driven development, and building reusable UI patterns

Demonstrated experience owning or significantly contributing to a shared component library or design system

Experience integrating and working with REST APIs in complex product environments, including real-time data, high-frequency updates, and large datasets

Strong understanding of HTML5, CSS, and modern browser-based application development

Familiarity with modern front-end build pipelines and tools such as Webpack, NPM, and related tooling

Ability to understand complex product and business requirements and translate them into clean technical solutions

Strong understanding of code organization, shared state patterns, and frontend maintainability at scale

Excellent communication, collaboration, and problem-solving skills, including the ability to influence technical direction across teams

Bonus

Experience contributing to open source projects

Familiarity with coding agents and AI-assisted developer tools such as Claude Code, Codex, or similar systems

Experience with Node.js fundamentals or broader full-stack exposure

Strong product sense and a good eye for building superior user experience, particularly in security, observability, or data-rich product domains

Experience with agile development processes
