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

• TypeScript (primary)
• React
• State: Zustand and React Query
• UI/Styling: Tailwind CSS and Material-UI (theming, design tokens, dark mode)
• Solana wallet adapters & TS tooling
• REST APIs (Fastify-backed)
• Modern frontend tooling (Vite, code-splitting, tree-shaking)
• Charts: Recharts, ApexCharts
• Web3/Solana: solana/web3.js, anchor, Jupiter wallet adapter + in-house custom built tools

Requirements

• Strong React + TypeScript fundamentals
• Experience owning complex async flows and failure modes
• Comfort working close to protocols, SDKs, and infrastructure
• High agency and able to work independently in an async, founder-led team
• Strong debugging instincts (eg. “it works, except when it doesn’t”)
• Solana / crypto integrations experience
• Include personal GitHub in resume or application

Compensation & Benefits

• $45k–$120k salary, (experience-dependent)
• Token equity upside
• Paid in USDC
• Fully remote
• Work directly with founders on core protocol surfaces
