The posting

About the Project

We’re building a borderless, self-custodial remittance app that lets users send, receive, and hold stablecoins (USDC / EURC) across countries, with on/off-ramp integration, account-abstraction wallets, and virtual bank accounts.

Our goal is to make stablecoin payments as easy as Revolut or Wise.

You’ll be joining a small, product-driven team building the first version of the app from the ground up.

Responsibilities

  • Lead the frontend architecture, design, and implementation of the web/mobile app.
  • Work closely with product, design, and backend teams to bring user flows to life.
  • Build clean, maintainable, and scalable codebases using modern frameworks.
  • Integrate with wallet SDKs, and Web3 libraries (ethers.js, viem, wagmi, etc.).
  • Optimize app performance, security, and responsiveness across devices.
  • Implement user onboarding, KYC, and account-abstraction wallet flows.
  • Set up reusable UI components, design systems, and frontend documentation.

Tech Stack

  • Framework: Next.js / React
  • Language: TypeScript
  • UI: TailwindCSS / ShadCN / Radix UI
  • State Management: Zustand / Redux Toolkit
  • API: REST & gRPC (for internal microservices)
  • Web3: ethers.js / wagmi / Privy / Reown SDK
  • Tooling: Vite / ESLint / Prettier / GitHub Actions
  • Mobile: React Native
  • Optional: Expo

Requirements

  • 5+ years of experience in modern frontend development.
  • Strong proficiency with React + TypeScript + Next.js.
  • Deep understanding of frontend architecture, security, and performance optimization.
  • Experience integrating with TypeScript-based backends (REST/gRPC/GraphQL).
  • Understanding of API design, authentication flows, and data models.
  • Familiarity with fintech or Web3 products (wallets, on/off-ramps, etc.).
  • Comfortable collaborating in small, fast-moving teams.
  • Ownership mindset.
  • Fluent English - required for daily team communication.

Nice to Have

  • Experience with account abstraction (ERC-4337) or embedded wallets.
  • Experience integrating on/off-ramps (e.g. LI.FI, Transak).
  • Some backend familiarity (Node.js / Go / gRPC) to collaborate better with backend team.
  • Past startup or fintech experience.

What We Offer

  • Join an early-stage fintech with a bold mission: bringing stablecoin finance to emerging markets.
  • Work directly with the founder & core engineering team on product decisions.
  • Remote-friendly, async-first culture with clear ownership.
  • Competitive pay.

Engagement

  • Full-time
  • Remote
  • Start: Within 1 month

Why it works

3×

more interviews than doing it yourself with ChatGPT.

ChatGPT writes a CV and never learns what happened to it. We see every reply. For each CV we know:

  • How it was written, and how the review scored it
  • When we applied, and how long after the posting went up
  • Which posting, which company, which city
  • Who got the interview, and who heard nothing

That is how we know which CVs get called.
