Senior Software Engineer, Stablecoin Payments
Team: Engineering
Location: Remote / USA
Commitment: Full-time
Workplace Type: remote
Salary:
About the Role
Flex is building stablecoin products for business owners, and we need engineers who can ship them. The team is small and moving fast, and you’ll be one of the first engineers to join. You’ll build the services that move customer money on-chain and connect them to the banking systems Flex already runs. That means real ownership, direct access to the engineering lead and product, and work that customers use.
Crypto experience helps, but it isn’t required. Much of the work is strong fintech engineering: payments, onboarding, compliance, and reliability. If you’ve built that kind of system and want to learn the crypto side, we want to talk.
What You'll Do
- 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 stand up to 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 set technical direction of the team’s roadmap
- Onboard and mentor new teammates
Requirements
- 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: accuracy, reliability, and handling failures safely
- Proficiency in a modern backend language
- Comfortable owning problems end to end in a small, fast-moving team
- Clear communicator with technical and non-technical partners
Nice to Haves
- 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
