Job Description

Location: Midtown, New York, NY (In-person Mon–Thurs, Remote Fridays)

Team: Engineering – Infrastructure & Operations

Company Description

At Fun.xyz , we believe a tokenized future is a beneficial inevitability, granting financial emancipation to everyone with an internet connection. For a blockchain-first global economy to exist, value exchange must become intuitive, secure, and seamless.

Enter Checkout - the highest converting payment solution in web3. By integrating Checkout, dApps enable users to complete any on-chain action using crypto from a wallet, centralized exchange, or on-ramped fiat from a card or bank account. With access to market-leading routing and their asset portfolio at the point of sale, users are faster, stickier, and more engaged. For dApps, Checkout scales their user acquisition potential without launching new chains or integrating multiple third party providers.

We built Checkout because we envision a world where anyone, anywhere, can purchase anything with any asset. If that sounds like a vision you can get behind, we want to hear from you.

• Collaborate with developers to ensure the platform is developer-friendly, testable, and highly available.
• Automate manual processes to improve system scalability, security, and performance.
• Occasionally contribute to tooling or services using TypeScript/ Node.js when needed.
• Support disaster recovery, backup strategies, and fault-tolerant architecture design
• Champion a DevOps culture of automation, collaboration, and continuous improvement

• You thrive at the intersection of systems engineering and developer enablement
• You’ve scaled platforms handling hundreds of transactions per second
• You build infrastructure that’s invisible when it works and resilient when it fails
• You take pride in automating everything and reduce toil wherever it lives
• You think of infrastructure not just as code—but as a critical product component

Why Join Us

• Play a pivotal role in reshaping the crypto payments industry
• Be part of a team where deep technical rigor meets relentless execution
