Senior Software Engineer, Stablecoin Payments

• Mission-critical problems: We build software that directly controls how money moves at scale.
• High bar, low ego: Small teams, exceptional people, real ownership.
• Speed over comfort: We prioritize execution, quality, clarity, and results.
• Enduring impact: What we’re building will define how a generation of owners runs their businesses.

• 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.
