Senior/Staff Software Engineer - Moonpay Enterprise

MoonPay Enterprise is for builders with something to prove. This isn't a "work on cool crypto stuff" company. It's a high-standards, high-velocity, high-accountability company building the operating system for value movement. If the internet moves information, we move value: crypto, stablecoins, tokenized assets, and whatever comes next. Four offerings make that real: fund, tokenize, trade, and spend. MoonPay Enterprise is the fund layer built for businesses. We power how stablecoins move through real financial operations: enterprises, fintechs, PSPs, wallets, and marketplaces running their treasuries, their cross-border flows, and their stablecoin operations on us. The goal is to make moving real money at scale as predictable as any other piece of financial infrastructure, with the compliance and controls CFOs need to say yes. AI is the default operating mode here. It's woven into every role, and we expect you to use it daily. It handles the manual work so you can deliver on what actually matters. You'll thrive here if outcomes excite you more than process, if impact motivates you more than titles, and if you want hard problems, real ownership, and teammates who love winning, building, and doing it together. The bar is high. The pace is real. We're building the rails that businesses run real money on, for humans and agents. MoonPay ranked #2 in Crypto Services on Fortune's inaugural Crypto 100 , made Forbes' America's Best Startup Employers 2026 (Top 25 in Finance), and landed on The Sunday Times Best Places to Work two years running. 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. Track 1: KYB / KYC & Compliance Platform Build the systems that let enterprises onboard safely and stay compliant across dozens of jurisdictions. You’ll own services powering business (KYB) and individual (KYC) verification flows, risk scoring, sanctions and AML screening, case management, and integrations with identity and compliance vendors. The challenge is making rigorous compliance feel invisible: fast, automated, and globally scalable, without ever compromising on regulatory obligations. Track 2: New Product Lines, starting with Custody Join us at the ground floor of new enterprise products, beginning with Custody. You’ll design the backend for secure digital asset storage and management for institutional clients: key management workflows, policy engines, transaction authorization, ledger integrity, and audit trails. This track suits engineers who love ambiguity, greenfield architecture, and building products from zero to one with enterprise-grade security requirements. Track 3: Blockchain, Stablecoin Issuance & On-Chain Infrastructure Work directly with blockchain protocols to power our stablecoin issuance business and on-chain products. You’ll build and operate services for minting, burning, and managing fully reserved stablecoins across chains, develop smart contract integrations on EVM chains and Solana, and design the indexing, monitoring, and reconciliation systems that keep on-chain and off-chain state in sync. Prior Solana (Rust) or Solidity development experience is a strong plus here. Across all tracks, experience with fiat rails, banking integrations, or payments systems is very welcome. Much of our hardest work happens where traditional finance and crypto overlap. 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 auditabilit
