About The Position

As a Staff Frontend Engineer, you'll own the design and delivery of the user-facing layer that makes AI capabilities accessible, trustworthy, and actionable — from experiment management and prompt testing to model evaluation dashboards and solution certification workflows. In this role, you will work hands-on to shape the experience strategy, establish frontend architecture, and build the interfaces that turn complex AI operations into intuitive, high-quality tools used across the enterprise.

Requirements

8+ years of frontend or fullstack engineering experience, with at least 3 years in a senior or lead capacity owning UX-critical product surfaces
Demonstrated track record designing and delivering complex, data-rich web applications with direct, hands-on engineering contribution at the most complex levels
Deep expertise in modern frontend frameworks (React, Next.js, or equivalent) and state management patterns for large-scale applications
Strong UX design sensibility — ability to translate complex workflows into clean, intuitive interfaces without relying on a separate design team for every decision
Proficiency in data visualization for technical audiences — experience with charting libraries (D3.js, Recharts, Visx, or equivalent) and dashboard design patterns
Hands-on experience building and maintaining design systems and component libraries (e.g., Storybook, custom libraries built on Radix, shadcn/ui, or similar)
Solid backend proficiency (Node.js, Python, or Go) to own API integration, contribute to BFF layers, and collaborate effectively with backend engineers
Experience with frontend testing strategies including unit testing, integration testing, visual regression testing, and end-to-end testing (Jest, Playwright, Cypress, or equivalent)

Nice To Haves

Experience building internal developer tools, platform UIs, or ML/AI tooling where the user base is primarily technical
Familiarity with AI/LLM concepts — enough to understand the domain and design meaningful interfaces for prompt testing, evaluation results, and model comparisons
Experience with accessibility standards (WCAG) and inclusive design practices in enterprise applications
Background in UX research methods — user interviews, usability testing, journey mapping — applied in a product engineering context rather than a standalone design role
Experience operating in regulated industries (financial services, healthcare) with familiarity of compliance-driven UI requirements such as audit trails and approval workflows
Contributions to open-source frontend projects, design systems, or technical publications at recognized forums

Responsibilities

Own frontend architecture and UX direction for the AI platform, defining component systems, interaction patterns, and design standards that scale across multiple product surfaces
Design and build the experimentation UI — enabling teams to configure, trigger, and compare prompt and model experiments with clear, data-rich visualizations of results
Create evaluation and observability dashboards that surface model quality metrics, latency, token usage, regressions, and drift in ways that are immediately actionable for technical and non-technical stakeholders
Build the solution certification workflow — guiding users through approval gates, audit trails, and compliance checkpoints with a seamless, transparent experience
Establish and maintain a shared design system and component library ensuring visual consistency, accessibility, and reusability across the platform
Drive UX research and user testing with internal teams (ML engineers, product owners, reviewers) to validate workflows, uncover friction, and iterate on designs before and after launch
Collaborate closely with backend and AI engineers to define API contracts, optimize data flows for the frontend, and ensure end-to-end reliability of user-facing features
Set and uphold frontend engineering standards — coding conventions, testing strategies (unit, integration, visual regression), performance budgets, and documentation expectations
Mentor and guide other developers on frontend and UX best practices, conducting design reviews and code reviews to elevate team quality
