FullStack Engineer TypeScript

Solomon Labs is building the dollar infrastructure layer for Solana. We design and operate USDv, a fully backed Solana-native stablecoin that streams yield onchain. Our mission is to turn on-chain dollars into a public utility: productive, composable infrastructure that wallets, protocols, and treasuries can plug into, and that everyday people can access as easily as holding a dollar. Over the next decade, a meaningful chunk of the world’s cashflows is going to live onchain. Solomon Labs is building the dollar rails for that world: USDv, sUSDv, and YaaS. A stablecoin stack where every dollar can earn yield by default, without changing how it behaves.  You’ll work directly with the founders, own problems end-to-end (from spec → programs → API → UI), and see your work sit on the critical path for how stables move and earn across Solana. This isn’t a “keep the lights on” role, it’s an all-in build phase with real ownership in the rails underneath the next wave of onchain finance.
