Every time someone buys crypto through MetaMask, OpenSea, or hundreds of other apps and wallets, there is a good chance MoonPay is processing that transaction behind the scenes. MoonPay is the infrastructure layer that connects traditional payment methods — credit cards, bank transfers, Apple Pay — to the crypto ecosystem. Over 500 partners integrate MoonPay's APIs to let their users buy, sell, and swap digital assets without ever leaving the host application.
This is an infrastructure business, and that distinction shapes everything about what it is like to work there. MoonPay is not building the flashiest consumer product or the most decentralized protocol. It is building the payment rails that other crypto products depend on. If you are drawn to the plumbing that makes an industry work, MoonPay is one of the most interesting companies in the space.
What MoonPay Actually Builds
MoonPay was founded in 2019 with a single product: a fiat-to-crypto on-ramp widget that partners could embed in their applications. That core product remains the foundation of the business, but the company has expanded significantly:
- Fiat on-ramp/off-ramp — The flagship product. Users can purchase crypto with credit cards, debit cards, bank transfers, and mobile payment methods across 160+ countries. MoonPay handles KYC, fraud detection, payment processing, and regulatory compliance so that partner applications do not have to
- MoonPay Swap — A cross-chain swap product that lets users exchange one cryptocurrency for another, integrated into partner apps alongside the on-ramp
- NFT Checkout — A product that lets users buy NFTs with a credit card in a single click. This powers NFT purchases on major marketplaces and has been used for high-profile drops
- Enterprise payments — Custom payment solutions for larger partners with specific compliance, volume, or integration requirements
- HyperMint — A no-code NFT infrastructure platform for brands and creators to launch, manage, and distribute NFTs
- MoonPay Concierge — A white-glove service for high-net-worth individuals buying crypto and NFTs
The revenue model is straightforward: MoonPay takes a fee on each transaction processed through its infrastructure. The more partners integrate MoonPay, and the more their users transact, the more MoonPay earns. This creates a classic network effect — being the default on-ramp in the most wallets and apps makes MoonPay the default choice for new partners.
MoonPay raised $555 million at a $3.4 billion valuation, with investors including Tiger Global, Coatue, and a notable roster of celebrity backers including Justin Bieber, Gwyneth Paltrow, and Snoop Dogg. The celebrity involvement is unusual for an infrastructure company but reflects MoonPay's strategy of positioning itself at the intersection of crypto and mainstream culture.
Engineering Culture
MoonPay has roughly 400 employees, with engineering comprising a significant portion of the team. The company is headquartered in Miami, with offices in London and other locations, and operates a hybrid model with substantial remote flexibility.
The engineering culture is payments-first. If you have worked at Stripe, Adyen, or another payments company, the daily concerns will feel familiar: uptime, transaction success rates, fraud prevention, regulatory compliance across jurisdictions, and the relentless complexity of moving money across borders. The crypto element adds another layer — blockchain confirmations, wallet integrations, token support, and the volatility of the underlying assets.
Teams are organized around products: on-ramp, swap, NFT checkout, enterprise, and platform infrastructure. Each team owns its product end-to-end, from API design to deployment to monitoring. The pace is startup-fast — MoonPay grew from a handful of people to 400 in just a few years, and the shipping velocity reflects that growth trajectory.
One distinguishing aspect of MoonPay's culture is its focus on partnerships. Because MoonPay exists as infrastructure inside other products, the engineering team works closely with partner integration teams. You will spend time understanding how MetaMask's checkout flow works, how OpenSea handles purchase failures, and how to optimize conversion rates across wildly different user interfaces that you do not control. This partner-facing dimension is unusual for backend engineers and adds a product-thinking element to technical roles.
What Roles They Hire For
MoonPay hires across engineering, product, and business functions, with a tilt toward payments infrastructure and partner-facing roles.
Engineering:
- Backend engineers (payments processing, transaction orchestration, API development)
- Frontend engineers (embeddable widgets, partner-facing SDKs, internal tools)
- Mobile engineers (MoonPay's own app and mobile SDK for partners)
- Infrastructure/DevOps engineers (AWS, Kubernetes, CI/CD, monitoring at scale)
- Security engineers (fraud detection, payment security, anti-money laundering systems)
- Data engineers (transaction analytics, conversion optimization, risk scoring)
- Blockchain engineers (wallet integrations, multi-chain support, smart contract interactions)
Product & Design:
- Product managers (payments UX, partner integrations, new product lines)
- Product designers (widget design, checkout optimization, dashboard interfaces)
Business:
- Partnership managers (managing integrations with 500+ partners)
- Compliance and legal (multi-jurisdiction payments regulation, KYC/AML)
- Sales and business development (enterprise payments deals)
- Marketing (brand partnerships, developer marketing, content)
The partner engineering and integration roles are distinctively MoonPay. If you enjoy the intersection of technical work and relationship management — helping a partner debug their integration, optimizing checkout conversion rates, building SDKs that are a joy to use — MoonPay has more of that work than most crypto companies.
Tech Stack
MoonPay's stack is modern payments infrastructure built primarily on TypeScript and AWS:
- Backend: TypeScript and Node.js for the majority of services. Python for data engineering, machine learning models (fraud detection), and analytics pipelines
- Frontend: React and TypeScript for web applications, embeddable widgets, and internal dashboards
- Mobile: React Native for cross-platform mobile development
- Infrastructure: AWS across the board — ECS, Lambda, RDS, DynamoDB, SQS. Kubernetes for container orchestration. Terraform for infrastructure-as-code
- Data: PostgreSQL for transactional data. Redis for caching. Snowflake for analytics. Custom real-time fraud detection pipelines
- Blockchain: Multi-chain integration layer supporting dozens of blockchains. Ethers.js and custom libraries for wallet interactions and transaction monitoring
The stack is intentionally boring in the best way. MoonPay is a payments company first and a crypto company second. The engineering challenges are about reliability, compliance, and conversion optimization more than about novel cryptographic systems. If you are a strong TypeScript/Node.js engineer with an interest in payments, you will be productive quickly.
Interview Process
MoonPay's interview process typically runs 3-4 rounds over 2-3 weeks:
- Recruiter screen (30 min) — Background, motivation, role fit. MoonPay recruiters tend to emphasize culture and product interest alongside technical qualifications
- Technical screen (60 min) — A coding challenge focused on practical problem-solving rather than algorithmic puzzles. Expect questions about API design, data modeling, or building a simplified version of a payments flow
- System design or take-home (varies) — Senior candidates get a system design round: design a multi-currency payment processing system, a fraud detection pipeline, or a partner integration architecture. Some teams use a take-home project instead
- Final round (2-3 sessions, 45 min each) — A combination of technical deep dive, product thinking, and culture fit. For engineering roles, expect discussions about past projects, how you approach production incidents, and how you think about building developer-facing products
Payments domain knowledge is a strong differentiator. Understanding PCI compliance, 3D Secure, chargeback mechanics, and the nuances of cross-border payment processing will impress interviewers. Crypto knowledge is helpful but not required for most roles — MoonPay actively hires from traditional fintech and payments companies.
Compensation
MoonPay pays at strong startup rates, particularly for engineers in the payments and infrastructure space.
Approximate ranges (2026, total compensation):
- Junior Engineer: $120k-$170k (base $100k-$130k + equity)
- Mid-level Engineer: $170k-$260k (base $140k-$180k + equity)
- Senior Engineer: $240k-$360k (base $180k-$230k + equity)
- Staff/Lead Engineer: $330k-$470k (base $220k-$270k + significant equity)
Equity is private company stock options. Given MoonPay's $3.4 billion valuation, the upside potential is meaningful but dependent on a future liquidity event — IPO, acquisition, or secondary sale. The company's revenue model (transaction fees on a growing payment volume) is more sustainable and predictable than many crypto businesses, which gives the equity a somewhat different risk profile than a pure DeFi play.
Benefits include health insurance, flexible PTO, remote work flexibility, and the Miami headquarters provides the standard startup amenities. MoonPay also offers a crypto stipend and education budget.
Why You Might NOT Want to Work There
MoonPay is a strong company, but the trade-offs are worth considering.
You will not be building on-chain. If your dream is writing Solidity or working on consensus algorithms, MoonPay is the wrong place. The engineering work is primarily traditional backend systems, payments processing, and API infrastructure. The blockchain interaction layer exists but is a small fraction of the overall codebase. This is a payments company that happens to deal in crypto, not a crypto-native protocol team.
Regulatory complexity is the core challenge. MoonPay operates in 160+ countries, each with its own payments regulations, KYC requirements, and crypto-specific rules. This regulatory surface area is enormous, and it affects engineering directly — you will build features that are only available in certain jurisdictions, handle compliance requirements that vary by geography, and navigate a regulatory landscape that is constantly shifting.
Celebrity association cuts both ways. MoonPay's high-profile celebrity investors and brand partnerships generate attention, but some engineers find the company's public image disconnected from the actual work of building payments infrastructure. If you prefer a lower-profile, engineering-driven culture, the MoonPay brand may feel like a mismatch.
Rapid growth growing pains. Scaling from a small startup to 400+ employees in a short period inevitably creates organizational challenges: processes that have not caught up to the team size, knowledge silos, and the occasional feeling that the company is building the plane while flying it.
Private market uncertainty. MoonPay raised at a $3.4 billion valuation during a frothy market. Whether the company grows into that valuation, or whether it needs a down round or extended timeline to liquidity, directly affects the value of your equity.
Should You Apply?
MoonPay is the right choice if you want to work on real payments infrastructure at the intersection of traditional finance and crypto. The problems are tangible — moving real money, in real time, across real regulatory jurisdictions — and the partner network means your work is used by millions of people through applications they already know. If you are a payments engineer looking for a crypto angle, or a crypto engineer who wants to work on something with immediate, measurable business impact, MoonPay hits that intersection.
It is the wrong choice if you want deep on-chain engineering, if the celebrity brand image bothers you, or if you need the certainty of public market liquidity for your equity. MoonPay is a startup that has grown fast, and working there means accepting both the energy and the messiness that come with that trajectory.
