Web3 Frontend Developer – Wallet Connect + Payment Flows

Seimus

This job is closed

About Us
We’re building the next generation of Web3 presale platforms — combining frictionless wallet connections, intuitive payment experiences, and scalable frontend systems. Our team moves fast, launches often, and is focused on delivering world-class UX for both crypto newcomers and degens.

We’re looking for a Frontend Web3 Developer to join full-time. You’ll own wallet connection logic, analytics integrations, and user flows — while also contributing to broader frontend features across our products.

🔑 What You’ll Do

- Build and optimize multi-wallet connect flows (MetaMask, WalletConnect, Coinbase, Phantom, etc.).

- Design and implement payment flows & presale widgets that are smooth, reliable, and conversion-focused.

- Develop analytics hooks to track user journeys, wallet errors, and drop-off points.

- Collaborate with product & design to deliver intuitive UX/UI for both beginners and advanced users.

- Contribute to broader frontend work (dashboards, landing pages, marketing integrations) as needed.

Ensure all features are mobile-first and high performance.

✅ What We’re Looking For

- Strong frontend experience with React / Next.js.

- Proven work on Web3 DApps (NFT mints, presale dashboards, or token sale widgets).

- Hands-on knowledge of wallet connectors (wagmi, ethers.js, viem, WalletConnect, Coinbase SDK, Phantom SDK).

- Strong sense of UI/UX best practices — designing flows that reduce friction and boost conversions.

- Experience with analytics integration (Mixpanel, GA4, custom event tracking, or similar).

- Problem-solving mindset: able to debug wallet/network edge cases and deliver smooth user flows.

🌟 Nice to Have

- Experience in token presales, ICOs, or large-scale Web3 launches.

- Understanding of crypto user psychology and how to design for both degens and first-time buyers.

🎯 What We Offer

- Competitive salary + potential token/performance based incentives.

- Remote-first, async-friendly team.

- Opportunity to work on high-visibility launches with strong marketing reach.

- A small, fast-moving team where your code directly impacts thousands of users.

What does a React developer in web3 do?

A React developer in the context of web3 is a developer who is using the React JavaScript library to build user interfaces for decentralized applications (dApps) that run on the Ethereum blockchain

These dApps often use smart contracts to facilitate transactions and other interactions on the Ethereum network

Overall, the role of a React developer in web3 involves using your skills in React development to help build cutting-edge decentralized applications that leverage the power of the Ethereum blockchain

As a React developer in web3, some of your responsibilities might include:

  • Integrating the dApp with the Ethereum blockchain. This might involve using tools like web3.js and Ethers.js to connect to the Ethereum network and interact with smart contracts.
  • Building the user interface for a dApp using React. This could involve creating components for the various elements of the dApp, such as buttons, forms, and other input elements.
  • Implementing features that are specific to decentralized applications, such as handling cryptocurrency transactions and displaying data from the blockchain in a user-friendly way.
  • Collaborating with other members of the development team, such as blockchain engineers and designers, to ensure that the dApp functions properly and meets the needs of the end users.
