Job Description

The Senior UX Engineer on the Enterprise UX team will support firmwide UX governance and co-lead our internal design system, ShadCN-based UI libraries, and UI standards across the applications that power investment, operations, and corporate workflows. This hands-on role is centered on improving usability, enforcing consistent patterns, increasing component reuse, and advancing accessibility across a broad internal product ecosystem. The ideal candidate has managed complex Figma design systems and works effectively across design, engineering, and product teams.

Key Responsibilities:

• Lead firmwide UX governance with practical standards, reviews, and adoption guidance.

• Co-own the internal design system with design, engineering, and platform partners.

• Co-govern ShadCN UI asset libraries, React patterns, and component usage.

• Maintain Figma standards for tokens, variants, components, and documentation.

• Translate Figma patterns into production-ready React and TypeScript components.

• Partner with application teams to improve UI consistency across internal products.

• Review high-impact workflows for usability, accessibility, and implementation quality.

• Define guidance for design tokens, theming, interaction states, and layouts.

• Support adoption through documentation, examples, and team enablement sessions.

• Stay hands-on through code review, prototyping, and technical design discussions.

• Raise the quality bar for reusable UI, front-end architecture, and developer experience.

Required Qualifications:

• 8+ years in front-end, UX engineering, or design-system engineering.

• Deep React, TypeScript, and modern component-library development experience.

• Proven experience managing large, comprehensive design systems in Figma.

• Strong knowledge of Figma libraries, tokens, variants, and governance practices.

• Experience scaling design systems used by multiple product teams.

• Practical experience with ShadCN, Radix, Tailwind, or comparable UI primitives.

• Ability to translate design standards into maintainable production components.

• Strong accessibility judgment across components, patterns, and workflows.

• Clear communication with engineers, designers, product leads, and senior stakeholders.

• Comfort setting standards without slowing delivery or team autonomy.

Preferred Qualifications:

• Capital-markets, trading, risk, or data-dense enterprise UI experience.

• Familiarity with real-time grids, charts, blotters, and workflow-heavy applications.

• Experience with monorepos, shared packages, build tooling, and developer platforms.

• Exposure to desktop interoperability, FDC3, OpenFin, Tauri, or WebView2.

• Experience using AI-assisted tools to accelerate design-system or UI delivery.

• Background supporting globally distributed product and engineering teams.

Primary Responsibilities:

• Firmwide UX standards, governance rituals, and adoption playbooks.

• Figma design-system libraries, tokens, components, and documentation.

• ShadCN-based UI asset libraries and reusable React/TypeScript components.

• Accessibility guidance, interaction patterns, theming, and visual consistency.

• Front-end enablement for teams building internal trading and analytics tools.

• Shared UI patterns for data-dense, workflow-heavy enterprise applications.
