• Comfortable with Tailwind CSS and component libraries, building responsive and accessible UI from designs.
• Working in a Vite + Turborepo monorepo.

Requirements — Common:

• Fintech experience (payments, accounts, money flows). This matters, not a nice-to-have.
• Multiple API integrations with external services: auth, retries, idempotency, webhooks.
• Real understanding of networking: TCP/UDP and how they actually work.
• Data formats and protocols: JSON, Protobuf, HTTP, gRPC.

Nice to have:

• KYC providers (Sumsub, Onfido or similar).

We Offer:

• 100% remote work.
