Senior Front-End Engineer: React, TypeScript, Dashboards & Design Systems | Remote USA | Up to $205K + Equity

"Design is not just what it looks like and feels like. Design is how it works." – Steve Jobs

You've built dashboards, data visualisations and real-time screens that technical users rely on every day. You've built a design system from scratch rather than just consuming one. And you've got a portfolio of shipped UI to prove it. If that's you, this is a first-front-end-hire role where you decide how the product looks and works.

The company

An early-stage, well-funded AI start-up with a small, senior team and a growing base of enterprise customers. Fully remote across the USA. You'd work directly with the CEO.

The role

You'll be the first front-end engineer. There is no front-end codebase and no design system yet, so you'll own both from day one and set the standard everyone else builds to.

What you'll build:

AI-generated answers that stream in and link back to their exact source

Review and approval queues for AI outputs

Document upload and correction workflows

Interactive data and relationship-graph exploration views

Dashboards tracking model and system performance

The component library and design system every engineer and customer-facing app will run on

This is product UI for technical users. Think analytics tool, not consumer app. Full-stack engineers whose strength is front-end are welcome.

What you must have

Shipped data-heavy product UI: dashboards, data or graph visualisations, real-time or streaming data views

Built and owned a design system or component library yourself (using one doesn't count)

A portfolio or live examples of UI you've shipped, ready to share with your application

3+ years of front-end engineering on B2B or data-heavy web apps (senior profiles preferred)

Production React and TypeScript

Nice to have

Early front-end hire at a start-up, building product UI from nothing

Full-stack comfort, happy to write an API endpoint when it's needed

Experience with Figma MCP or similar AI design-to-code tooling

Probably not the right fit if

Your experience is mainly marketing sites, landing pages or e-commerce checkout

You're a backend-leaning full-stack engineer with limited front-end ownership

Compensation and logistics

Base $150K–$205K, depending on experience

Competitive equity, weighted for an early hire

Fully remote within the USA

Full-time

US citizens and Green Card holders only. No visa sponsorship is available for this role

Interview process

Live, conversational technical interviews. No take-home test, no live coding. Four rounds, roughly two and a half hours in total.

How to apply

Apply with your resume and a link to your portfolio or live work. Applications without examples of shipped UI won't progress, so include the link.

You can also email Keiran Hathorn directly at [email protected] with your resume and short answers to these three questions:

Describe a data-heavy UI you've shipped (dashboard, graph visualisation, real-time or streaming view). What did it do and who used it?

Have you built and owned a design system or component library from scratch? What did it cover and who else built on it?

A link to your portfolio or live examples of UI you've shipped.
