Senior Software Engineer, Stablecoin Payments
About This Role
Crypto experience is helpful but not required. Much of the work is strong fintech engineering—payments, onboarding, compliance, and reliability. If you've built systems like that and want to learn the crypto side, Flex wants to hear from you.
What You'll Be Doing
Design, build, and run backend services for stablecoin payments, including deposits, withdrawals, and on- and off-ramps
Integrate with partners for wallets, virtual accounts, and stablecoin orchestration
Build business onboarding (KYB) and compliance flows that can withstand banking audits
Connect new stablecoin products to Flex's existing banking, ledger, and payments systems
Own your work from design through launch and production support
Work closely with product, design, compliance, and business development
Help shape the technical direction of the team's roadmap
Onboard and mentor new teammates
What We're Looking For
5+ years of backend software engineering experience
Experience building and running production services in fintech, payments, or banking
Experience with compliance-driven systems such as KYB, KYC, AML, or audit requirements, and comfort working with compliance stakeholders
Strong system design skills, especially for money movement, with attention to accuracy, reliability, and safe failure handling
Proficiency in a modern backend language
Comfort owning problems end to end in a small, fast-moving team
Clear communication skills with both technical and non-technical partners
Bonus Points
Hands-on crypto experience: stablecoins, wallets, custody, on-chain transactions, etc.
Experience with on- and off-ramps, virtual accounts, or stablecoin orchestration
Smart contract development or auditing experience
Prior experience at a startup or high-growth company
