## About the Role

* A product engineer: you care about the user experience and the business problem, not just the ticket, and you'll push back or propose a better approach.
 * A self-starter who is self-motivated and independent: you find the next most important thing and do it without waiting for direction.
 * Comfortable with ambiguity and with wearing many hats. In a small team, that means picking up work outside your core area when it matters.

Nice to have

 * Fintech, brokerage, or banking experience, especially account onboarding with identity and compliance checks.
 * Experience building white-label or embeddable products for B2B customers.
 * Experience integrating fintech SDKs such as Plaid or Persona, or e-signature tools.
 * Comfort with AI-assisted development such as Claude Code, which the team uses heavily.

## Description

You'll be our lead front-end engineer and operate like a founding product engineer: owning our partner-facing web products end to end, shaping what we build as much as how, and working directly with product, design, and backend engineers. This role is for a self-starter who wants real ownership and is happy to step outside a narrow job description when the team needs it.

What you'd work on

 * Partner-facing web products, owning them end to end from design handoff through to release.
 * The embeddable onboarding module. This is the white-label, co-branded UI that fintech partners embed so their customers can open brokerage accounts, both individual and business. It covers multi-step application flows for business accounts, adding and verifying owners and signers, and identity and compliance checks. One codebase produces several apps and partner-specific builds.
 * The partner dashboard. Partners use it to view and manage their customers' accounts: positions, statements, account reporting, joint and advisory account details, and settings such as notification contacts.
 * Self-service features that cut down on manual operations work, for example, letting partners edit business details or add participants to existing accounts without filing a support ticket.
 * Moving to a new version of our business-account API. That means rebuilding flows on a new data model in step with backend engineers.
 * Keeping two codebases healthy, including bringing the onboarding module's dependencies up to date with the dashboard's.

Our frontend stack

 * Core: TypeScript, React, Vite, Tailwind CSS
 * Components: Radix UI and React Aria, with Storybook for component development
 * Forms and data: React Hook Form with Zod, SWR
 * Server-side: Node.js (Koa) talking to our services over gRPC
 * Integrations: Plaid, Persona, Auth0, LaunchDarkly

What you will excel at

 * 4+ years building production web applications with React and TypeScript.
 * Building complex, multi-step forms and data-heavy screens, with careful validation, edge cases, and error states.
 * Working in the Node.js server layer behind our web apps (Koa, gRPC, Postgres), not just the browser.
 * Agreeing on API contracts with backend engineers, and pushing back when an API makes the UI hard to build.
 * Working directly with design and product, turning Figma designs and product tickets into shipped features.
 * Owning the release process: our workflow runs from preview environments through UAT to production.
