About the role

The Role:

We are seeking a hands‑on Frontend Tech Lead who thrives in building from 0‑1 and driving execution, directly contributing production‑level code while shaping our core technical foundation. You will collaborate closely with the founding team to architect, develop, and scale F2’s AI‑driven enterprise UI platform.

What you’ll do:

  • Hands‑on UI system building. Architect and implement foundational frontend infrastructure and features, actively coding and delivering critical React/TypeScript components from scratch.

  • Own the frontend architecture. Define and execute the technical vision and multi‑year roadmap for our React‑based UI platform, ensuring rapid iteration and effective scaling of user‑facing experiences.

  • Design for performance, security, and accessibility. Build high‑performance, responsive interfaces that meet SOC 2 and accessibility requirements, with a focus on maintainability and cost‑efficiency.

  • Integrate AI at the UI layer. Collaborate with our team to integrate intelligent agents, data visualizations, and interactive tools that surface AI‑driven insights within the application.

  • Establish frontend engineering excellence. Set and uphold coding standards, component library conventions, and review processes; mentor engineers to foster a culture of reliable, test‑driven frontend development.

  • Cross‑functional collaboration. Partner with product, design, backend, and enterprise customers to translate requirements into elegant UI solutions and deliverables.

What you bring:

  • Hands‑on technical leadership. 7+ years building and scaling mission‑critical frontend systems in TypeScript and React, with demonstrated experience architecting from the ground up.

  • Practical API design expertise. Deep experience designing and consuming RESTful and GraphQL APIs, including state management and efficient data‑fetching strategies.

  • Execution‑driven mindset. You thrive in environments where you own features end‑to‑end, iterate rapidly, and deliver production‑ready UI solutions.

  • Familiarity with CSS‑in‑JS (e.g. Styled Components, Emotion) or utility‑first frameworks (e.g. Tailwind), as well as Next.js, Webpack, and frontend performance profiling.

  • Passionate builder who enjoys solving complex UI challenges and iterating toward clear, impactful goals.
