Silver.dev - Control - Staff Frontend Engineer

• Leverage AI tools as a daily force multiplier — for code generation, component scaffolding, testing, and problem-solving. At Control, AI is infrastructure, not a novelty. • AI tools • Contribute to architectural and product decisions as a senior voice on a small team. • architectural and product decisions • 10+ years of professional software engineering experience with a track record of technical leadership and frontend ownership. • 10+ years • 8+ years building production React applications with TypeScript. • 8+ years • React applications with TypeScript • Product vision and user-centric thinking — you don't wait for a PM to tell you what matters. You develop a point of view on what the product should be, you advocate for the user in every technical decision, and you proactively identify opportunities to improve the experience. You see yourself as a product engineer who happens to work on the frontend, not a frontend engineer who occasionally thinks about the product. • Product vision and user-centric thinking • Strong grasp of crypto UX challenges: transaction states, gas estimation, address validation, network switching, signing flows, and the trust dynamics unique to custody products. • Strong grasp of crypto UX challenges • Deep knowledge of modern frontend state management — Redux Toolkit, React Query / TanStack Query. • modern frontend state management • Experience with Vite, TailwindCSS, and modern React patterns (Server Components awareness, concurrent features, composition patterns). • Vite, TailwindCSS • Strong UI craft and product instinct — you care about detail, trust signals, loading states, edge cases, error recovery, and responsive behavior. • Strong UI craft and product instinct • Comfortable working directly from Figma and contributing product and UX feedback — not just executing designs, but improving them. • Figma • Experience building and maintaining a design system in production. Experience writing automated tests across unit, integration, and E2E layers. • building and maintaining a design system • automated tests • Comfortable owning features end-to-end and operating autonomously in a small, remote team. • owning features end-to-end • Highly Valued • Production experience building interfaces for blockchain, cryptocurrency, or fintech applications — wallets, custody platforms, exchanges, DeFi dashboards, or wealth management products. Candidates with direct crypto or fintech backgrounds will be strongly preferred. • blockchain, cryptocurrency, or fintech applications • Experience with Dynamic.xyz, WalletConnect, or similar wallet connectivity infrastructure. Familiarity with Node.js / TypeScript APIs — enough to navigate the backend, understand • Dynamic.xyz • , WalletConnect • Node.js / TypeScript APIs • data contracts, and unblock yourself.

You build custom AI workflows, integrate AI into your development pipeline, and continuously push what's possible. • AI development tools • Experience in private banking, wealth management, or high-trust product design where the UX carries fiduciary weight. • private banking, wealth management, or high-trust product design • You see yourself as a product engineer first. You develop a vision for what the experience should be and you fight for it. • You believe that great frontend engineering is the difference between a product people tolerate and a product people trust with their wealth. • You are drawn to the idea of building something that lasts — interfaces that families rely on for decades. • You default to action. You ship, you iterate, you own the outcome. • You treat AI as a collaborator. You actively push the boundaries of how AI tools can improve your engineering output. • You obsess over the details that most engineers skip — the micro-interactions, the error states, the moments where a user decides whether to trust the product. • You are energized by greenfield work and the responsibility that comes with defining the frontend from scratch.
