About MoonPay

Hi, we’re MoonPay. We’re here to onboard the world to the decentralized economy by making digital money move as universally and effortlessly as the internet.

Why?

Because crypto, stablecoins and blockchain aren’t just technologies. They’re tools for global financial empowerment. They give people and businesses more control over their money, their digital assets, and their future, opening access to legacy financial systems that have been out of reach for many.

What we do
MoonPay is a unified payments platform for digital currency. We make it easy for anyone, anywhere, to buy, sell, swap and pay in digital currencies as easy as sending an email. That simplicity is intentional, our focus is reducing complexity so people can participate confidently, without needing to be crypto experts. We power the entire flow between fiat and crypto end to end, with compliance, identity checks, fraud prevention, and settlement all built in. This end-to-end approach reflects how we work internally: with accountability, rigor, and trust built into everything we ship.

Proven at scale

Trusted by over 30 million customers and over 500 ecosystem partners, our secure, enterprise-grade platform is driving mainstream crypto adoption worldwide. Behind those numbers are millions of real people and organizations relying on MoonPay every day.

We collaborate with innovative brands and projects to build secure, scalable solutions for a blockchain-powered future. This is an opportunity to help shape systems, not just scale them. And we’re committed to doing it right. Fully licensed in the U.S. and regulated across the UK, EU, Canada, and Australia, because trust and compliance are non-negotiable.

But we’re just getting started. We’ve launched a consumer app that makes crypto accessible, intuitive, and usable for everyone, and it’s growing fast. We’re iterating every day to make it the best it can be.

If you believe financial freedom should be for everyone. If you believe in building a fairer, more open financial system - we want you with us. To build systems that benefit all, we need contributions from all, regardless of background.

Come build the future of payments and the decentralized economy with MoonPay. Let’s make financial freedom and autonomy the new normal.

🌍 Locations Supported

This role can be performed remotely from the United Kingdom, Poland, South Africa, Spain, Portugal, or Romania.

Unfortunately we do not offer business to business contracting arrangements.

🌔 About the Opportunity

Our engineering discipline builds the technology that enables MoonPay to learn quickly and scale easily. We currently have squads across Crypto / Payments / KYC / Core Product and others. We're pragmatic and believe in having a fluid structure; this means people can find opportunities in different domains or go deeper into a particular domain.

🚀 What you will do

  • Architect and develop new and existing products and features on monetization.

  • Work with the head of monetization, other data scientists, and engineers to implement new experimentation and algorithmic pricing features across RAMPs, DeFi Trading, and Swaps.

  • Collaborate with other product teams to deliver and improve customer-facing features.

  • Contribute to the estimations, planning, and execution of projects, features, and integrations.

  • Integrate and work closely with external service providers that we use to power our services.

  • Maintain and improve our existing codebase.

  • Write fully tested, high-quality, performant code.

💻 What you will be working with/on

  • Typescript as our programming language of choice

  • Node.js as our backend platform

  • Google Cloud Platform to host our services

  • Git/GitHub for code collaboration

  • Launch Darkly for feature flags and experimentation

  • DataDog for logs, real-time alerting and monitoring

  • Argo CD for deployments

  • Redis for caching

  • React as our web frontend

  • Big bonus points if you also have some working experience with React Native

  • GenAI tools such as Cursor

🧑‍🚀 About You

  • Extensive full-stack engineering experience at leading startups or fast-growing tech companies, ideally from marketplace or platform-type businesses where algorithmic pricing and AB testing were heavily used.

  • Experience working on projects involving pricing, promotions, rewards, and/or loyalty programs with backend and frontend technologies.

  • Experience building experimentation platforms and infrastructure for algorithmic pricing solutions, and know how to leverage continuous delivery for it.

  • Confident in developing, releasing and maintaining server applications in a fast paced, iterative environment where we work as a team, and not in silos.

  • Experience with our tech stack, or confident you can cross-train and up-skill quickly.

  • Deep understanding of database structures and system design.

  • Cloud native experience with Google Cloud or similar (e.g. AWS, Azure).

  • Bonus points if you make open-source contributions or have experience in Web3.

We’re looking for people who live our core values, those who strive for excellence and want to leave a lasting legacy on the global financial system. Our values:

B - Be Hungry
L - Level Up
O - Own It
C - Crypto Curious
K - Kaizen

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.
