Your mission
Lead the technical execution, architecture, and engineering excellence of the 1inch web dApp. This is a hands‑on technical leadership role where you'll shape the architecture of a security‑critical Web3 application used to access decentralized finance. You'll build secure, scalable, and high‑performing frontend systems, guide engineering decisions across wallet interactions and blockchain integrations, and help establish engineering standards that balance delivery speed with quality, security, and long‑term maintainability.
What You’ll Do
- Lead the technical direction and frontend architecture of the 1inch web dApp, with security as a core design principle.
- Build production code for critical features, complex Web3 user journeys, and performance‑sensitive areas.
- Design and improve secure integrations with backend services, blockchain APIs, wallet providers, signing flows, approvals, swaps, and transaction lifecycle management.
- Establish and uphold engineering standards for security, performance, accessibility, testing, and code quality.
- Drive secure‑by‑design engineering practices and improve the reliability and resilience of wallet‑related functionality.
- Mentor frontend engineers through technical guidance, code reviews, hiring, onboarding, and ongoing development.
- Drive the adoption of AI‑assisted engineering practices while maintaining rigorous engineering quality, security, and maintainability.
- Collaborate with product, design, backend, mobile, QA, and analytics teams to deliver scalable, reliable features and improve the long‑term health of the platform.
Who You Are
- 6+ years of professional frontend or full‑stack development experience, including experience in a senior or technical leadership role.
- Strong knowledge of TypeScript and Angular, with experience building, shipping, and maintaining large or complex production web applications.
- Strong understanding of frontend architecture, state management, application design patterns, and performance optimization.
- Experience integrating REST and Web3 APIs in production environments, including wallet providers, signing, multi‑chain user experiences, and libraries such as ethers.js, viem, or web3.js.
- You have extensive practical experience using Cursor AI or comparable AI‑native engineering environments.
- Experience applying secure engineering practices, threat modelling principles, and securely handling sensitive user and wallet‑related data in production environments.
- Experience with Git, CI/CD pipelines, collaborative code review processes, and AI‑assisted engineering workflows with appropriate quality controls.
- Experience mentoring engineers, raising engineering standards, and communicating effectively with both technical and non‑technical stakeholders.
- Strong ownership mindset and problem‑solving skills.
Nice to haves
