Senior / Lead Front-End Engineer (UI Architecture & Governance)

We are seeking two Senior / Lead Front-End Engineers to join UI/UX Governance layer team. Instead of clicking standard backlog tasks for a single product, you will act as internal consultants and architects for an ecosystem of 100+ internal apps and 800+ developers. Your primary mission will be to help clear a massive technical backlog and guide internal teams through a major architectural shift.

Key Responsibilities:

• Advise and support internal engineering teams on front-end architecture, bespoke widget implementation, and web performance best practices.
  

• Develop, maintain, and extend highly optimized, reusable UI components (published as internal NPM/PNPM packages) for the corporate marketplace.

• Drive the technical migration of the internal design system from Material UI (MUI) to Shadcn, specifically optimizing it for AI-assisted/agentic developer workflows (Cursor, Copilot).

• Provide technical mentorship, perform architectural code reviews, and handle technical doubts from a massive pool of internal developer stakeholders.

IMPORTANT!

Due to strict financial regulatory requirements, the selected candidate must successfully pass:

• Standard background and criminal checks.

• Trading Portfolio Disclosure: Candidates must disclose their personal stock trading portfolios to the Compliance Department to prevent conflicts of interest.
  

Requirements

• Exceptional, expert-level proficiency in TypeScript and ReactJS. We are looking for true foundational experts who understand the inner workings of the language and framework.

• Experience with Shadcn and Tailwind CSS is highly desirable (aligning with our V2 architecture).

• Strong comfort level leveraging and optimizing for AI-assisted coding tools (e.g., Copilot, Cursor, or similar workflows).

• Superb interpersonal and consultative soft skills. You must be able to articulate technical decisions clearly, handle pushback from senior internal devs, and act as an internal advocate for UI standards.

• Professional fluency in English.

Nice-to-Have :

• Experience with complex data visualization, plotting, and charting libraries.

• Heavy experience with highly customized data grids, specifically AG Grid (used in ~80% of our applications).

• Understanding of modern Desktop Container Platforms (e.g., OpenFin, Interop.io) or Web Components.

• Basic understanding or awareness of Rust.
