Software Engineer, Front End

We are a fast-growing, mission-driven company powering the expansion of financial services and wealth creation, with billions of assets under management. We build critical financial infrastructure that allows consumer-facing companies to offer engaging investing experiences to their customers in a frictionless way. We are a team of financial empowerment enthusiasts who have come together from various industries, including tech, banking, finance, and law.

At Atomic, with billions of dollars in assets under custody, you will help build the front end that helps make it easier for ordinary individuals to secure their financial prosperity. Location: Atomic is a remote-first company, and this role is fully remote; 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. Partner-facing web products, owning them end to end from design handoff through to release.

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. 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 recent version of our business-account API. That means rebuilding flows on a new data model in step with backend engineers.

Our frontend stack

Core: TypeScript, React, Vite, Tailwind CSS

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

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.

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.

In a small team, that means picking up work outside your core area when it matters.

Fintech, brokerage, or banking experience, especially account onboarding with identity and compliance checks.

Experience building white-label or embeddable products for B2B customers.

Comfort with AI-assisted development such as Claude Code, which the team uses heavily.
