    This is the beating heart of wring.co. If this seat is empty:

    • We can’t ship product at the speed early customers expect.
    • There is no technical owner to set the bar for code quality, reliability, and velocity.
    • We won’t have the foundation of a culture that values both rigorous engineering and pragmatic execution.
      This role is the difference between a promising idea and a real business.

    The Kind of Person We’re Not Looking For

    Let’s be directβ€”if you:

    • Clock in at 9 and out at 5 without thinking about the mission.
    • Prefer to be told exactly what to build, rather than spotting problems and owning solutions.
    • Find the idea of talking with customers or recruiting engineers β€œsomeone else’s job.”

    This isn’t going to be a fit. We want grit, curiosity, and a genuine excitement about shipping products end-to-end.

    Core Responsibilities

    1. Own the Technology End-to-End
      • Architect, build, and maintain the core platform.
      • Make technical decisions with long-term scalability in mind.
    2. Build and Lead the Engineering Team
      • Recruit, onboard, and mentor early technical hires.
      • Shape engineering culture and processes.
    3. Collaborate Directly with Customers
      • Join implementation calls, understand pain points, and translate them into solutions.

    Success Metrics

    1. Fast, High-Quality Shipping
      • Consistently deliver key features and improvements on aggressive timelines without compromising quality.
    2. Clear, Usable Documentation
      • Internal and customer-facing technical documentation that is clear, up-to-date, and easy to navigate.
    3. Technical Ownership
      • The product is stable, performant, and evolves rapidlyβ€”because you own it, end-to-end.

    • Solid understanding of blockchain fundamentals: transactions, the mempool, gas, blocks, and smart contracts.
    • Hands-on experience interacting with ERC-20 and/or SPL token contracts.
    • A proactive and security-first mindset, especially when dealing with private keys and on-chain funds.

       

    How to know if you are the right fit:

    • You understand what GAS is, why it's needed, what is difference between sending ETH and ERC20 tokens. You are familiar with the concept of a dedicated "gas wallet".
    • You know the DIfference betwen DEX and CEX. You understand what is Automated Market Maker (AMM) on a DEX works and can explain its key differences from a traditional Central Limit Order Book (CLOB) found on CEXs.
    • You have practical experience sending tokens between wallets and calling methods on smart contracts.
    • You are excited by the challenge of building a secure and scalable system that manages a large number of wallets and performs on-chain actions.
