Senior/Staff Software Engineer - Moonpay Enterprise

The role

We’re hiring backend engineers across several openings within MoonPay Enterprise. All roles share the same foundation of designing and operating reliable, secure, high-throughput backend services, but each opening has a distinct focus. When you apply, tell us which track (or tracks) excites you most.

What you’ll do

• Design, build, and operate backend services written in Rust that process high volumes of financial transactions with strong guarantees around correctness, idempotency, and auditability
• Own features end to end, from shaping the product spec through technical design, implementation, testing, deployment, and production monitoring. You won’t just receive work from product: as a domain expert, you’ll help define what we build and propose the work you consider most useful
• Integrate with external partners such as banks, payment processors, blockchains, and identity and compliance vendors, and build the abstractions that make those integrations reliable
• Improve engineering quality across observability, incident response, security practices, and API design
• Collaborate closely with product, compliance, and other engineering teams across MoonPay’s global network
• (Staff level) Set technical direction for your area, mentor other engineers, and drive architectural decisions that span multiple teams

About you

• 5+ years of backend engineering experience (8+ for Staff), with a track record of shipping and operating production systems at scale
• Strong backend experience with a statically compiled language (e.g. Rust, Go, C#, C++) is a must. Deep fundamentals matter more to us than your specific language history
• Prior professional Rust experience is not required, but interest in Rust and motivation to become an expert in it are very welcome, since our services are written in Rust
• Solid fundamentals in distributed systems, API design, data modeling, and asynchronous processing
• Comfort working in domains where precision matters, such as financial systems, double-entry ledgers, reconciliation, or similarly correctness-critical software
• A pragmatic, autonomous, ownership-driven mindset. You care about outcomes, communicate clearly, and thrive on high throughput: on this team, features ship in hours to days and products in days to weeks
• Strong critical thinking, including in how you use AI tools. You know how to drive AI-assisted development productively while staying firmly in control of correctness, security, and design quality
• Interest in crypto, stablecoins, and the future of payments. Prior crypto experience is a plus rather than a requirement, except for Track 3, where hands-on blockchain development experience is expected

Bonus points

• Professional or hobby experience writing Rust (open-source contributions count!)
• Experience in fiat payments, banking integrations, card networks, or PSPs
• Familiarity with KYC/KYB, AML, sanctions screening, or regulated financial products (Track 1)
• Background in custody, key management (MPC/HSM), or institutional-grade security (Track 2)
• Smart contract development in Solidity (EVM) or Rust (Solana), and experience with on-chain indexing or node infrastructure (Track 3)
• Experience working in regulated, multi-jurisdiction environments

Benefits & Perks 💡

• Research has shown that women are less likely than men to apply for this role if they do not have experience in 100% of these areas. Please know that this list is indicative, and that we would still love to hear from you even if you feel that you are only a 75% match. Skills can be learned, diversity cannot.
