AI SummaryPhantom is hiring a Senior Software Engineer, Frontend to own and deliver features for its web platforms, including the Phantom Extension and website. The role involves leading new blockchain-support initiatives and complementary product or infrastructure launches in a fully remote, crypto-focused environment. Candidates need 5+ years of full-time engineering experience and strong React, TypeScript, and React-Query capabilities; Solana web3.js or ethers.js experience is also relevant. The engineer will engage directly with users and developers, translate feedback into product direction, and contribute to a high-bar engineering culture. This is a senior individual-contributor role with substantial product ownership and technical leadership expectations. ## Role DNA A quick view of the complexity, pace, ownership and collaboration implied by the job description. ### Job Complexity 4/5EasyHard ### Pace & Pressure 4/5RelaxedFast-paced ### Autonomy Level 5/5GuidedFull ownership ### Communication Load 4/5IndependentCollaborative AI insightThis role requires senior frontend depth alongside familiarity with Web3 concepts, wallet-adjacent products, and blockchain integrations.

How would you design a responsive and reliable interface for blockchain wallet or transaction interactions? I would model transaction states explicitly, validate inputs early, surface network and signing status clearly, handle failed or delayed confirmations gracefully, and ensure users can safely recover from interrupted flows without losing context. What practices do you use to keep a large React and TypeScript codebase maintainable? I use clear component and domain boundaries, strongly typed interfaces, reusable hooks, consistent state-management patterns, automated tests for critical flows, code review standards, and incremental refactoring to prevent complexity from accumulating. How have you used user or developer feedback to influence an engineering roadmap? I group feedback by frequency, severity, and user impact; validate themes with product and support data; then turn the strongest findings into actionable requirements, prototypes, or prioritized technical improvements. What considerations are important when integrating Solana web3.js or ethers.js into a frontend application? I would consider wallet-provider compatibility, network and chain-state handling, transaction serialization and signing flows, RPC reliability, error normalization, secure handling of public account data, and clear user messaging for on-chain latency or failures.
