About

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. Our frontend is where users experience that world: turning complex rails, yield mechanics, and onchain activity into clear interfaces, predictable interactions, and experiences that feel precise and trustworthy. This role is for a
Frontend Engineer
who treats crypto UX correctness as a systems problem. Solana UX today is fragile: wallet adapters leak abstractions, RPC behavior is inconsistent, and many integrations fall short of production-grade reliability. Your job is to make all of that invisible to users. You’ll work closely with the founders to ship core product features end-to-end, owning frontend integrations and interaction flows that sit directly on the critical path of the UX/UI. Responsibilities
Own and maintain integrations with Solana/DeFi libraries and products (eg. wallets, swap widgets, protocol SDKs)
Rewriting, wrapping, or replacing third-party libraries as needed to meet production reliability standards
Contribute to general frontend feature development and bug fixing Design and implement robust interaction UX, including:
simulation, submission, confirmation, and recovery wallet connection error handling and retry pathing
Improve UX across edge cases (eg. RPC variability, partial failures, inconsistent responses) Translate Figma designs into high-fidelity, production-ready React components Collaborate closely with Product, Design, and Engineering to realize client behavior into product reality. Tech Stack
