Full-Stack Engineer

You'll work across the entire product, mobile, web, and backend, as a true full-stack engineer and the connective tissue between our frontend and backend specialists. When either side needs capacity, you can absorb the work and ship it end to end, without a handoff. This is the role for someone who's just as comfortable wiring up a React Native screen as they are writing the service and data model behind it. Most of our features touch the whole stack: a user action on the phone, a validated API call, a change in the data layer, and a status update back to the user. You'll own features like that end to end. We're a small team that values engineers who can move fluidly between layers rather than throwing work over a wall. You'll pair closely with our frontend and backend leads, picking up work on both sides and keeping the product moving without bottlenecks.

What You'll Do

Build and ship features end to end across React Native (mobile), React (web dashboards), and a serverless TypeScript backend

Implement product flows from UI and data entry through API logic, persistence, and status/error handling

Write and consume clean API contracts, with shared validation schemas across mobile, web, and backend

Own integrations with financial and payment-rails partners, wiring third-party APIs and webhooks (payment processors, settlement rails, KYC, banking) into our services with idempotent, faulttolerant handling

Work in a serverless AWS stack (Lambda, DynamoDB) with TypeScript infrastructure-as-code

Collaborate with the frontend and backend leads, absorbing work on either side as priorities shift

Keep an eye on quality where it matters: typed interfaces, sensible tests, and correct handling of edge cases in a financial product

Help maintain a clean, shared monorepo where types and components are reused, not duplicated

Use AI-assisted development as your default workflow, and help keep our shared context docs current so teammates and agents stay informed
