About AlphaFC

AlphaFC is building a fan-governed football platform that connects real-world clubs with digital governance. The platform includes live stats, rosters, game commentary, fan voting, and an upcoming team token (ATFC).

We are entering a new phase focused on stability, quality, and expansion of core features, and are looking for a senior engineer to take long-term ownership of the platform alongside product and operations leadership.

The Role

Responsibilities

  • Own and evolve the AlphaFC platform across:

    • Frontend (React / Next.js)

    • Backend (Node / APIs)

    • Solana / smart contract components (governance, voting, token logic)

  • Implement and iterate on core features, including:

    • Onchain voting and governance mechanisms

    • Platform performance and data accuracy

    • Player and team pages, including video-first content

  • Improve:

    • Code quality and structure

    • Developer experience and documentation

    • Reliability, security, and observability

  • Work closely with product and design to translate requirements into robust implementations

  • Support and eventually help onboard additional engineers

What We’re Looking For

Must Have

  • Strong full-stack background

  • Experience building and maintaining production systems

  • High standards for code quality and maintainability

  • Clear, direct communication and comfort receiving and giving feedback

  • Ability to work independently and take ownership

Strong Plus

  • Web3, token, or onchain governance experience

  • Experience with data-heavy or real-time applications

  • Early-stage startup experience

  • Prior experience mentoring or leading other engineers

  • Familiarity with Supabase, Vercel, or similar platforms

What Success Looks Like

  • The platform becomes easier to understand, maintain, and extend

  • Core features are stable, accurate, and trusted

  • New engineers can onboard smoothly

  • Technical decisions are documented and intentional

  • Product iteration speeds up without sacrificing quality

How to Apply

Please include:

  • Brief background (or LinkedIn/GitHub)

  • Examples of relevant projects or systems you’ve owned

  • Any experience with smart contracts or governance systems (if applicable)

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.
