About the role
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.
Who you are
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.
