Senior/Staff Software Engineer - Moonpay Enterprise

MoonPay

60d•$180,000 - $300,000•Hybrid

About The Position

MoonPay Enterprise is seeking backend engineers for several openings. All roles involve designing and operating reliable, secure, high-throughput backend services. The company emphasizes high standards, velocity, and accountability, building the operating system for value movement, including crypto, stablecoins, and tokenized assets. AI is a default operating mode, expected to be used daily to handle manual work. The ideal candidate is motivated by outcomes, impact, and solving hard problems with real ownership and collaborative teammates. MoonPay has received recognition from Fortune and Forbes for its work in crypto services and as a top startup employer.

Requirements

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.

Nice To Haves

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.

Responsibilities

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.
Help define what we build and propose the work you consider most useful as a domain expert.
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 MoonPayâ€™s global network.
(Staff level) Set technical direction for your area, mentor other engineers, and drive architectural decisions that span multiple teams.
