Full job description
1inch is the DeFi ecosystem building financial freedom for everyone. 1inch products help users and builders trade, hold and track digital assets – with the self-custody, comprehensive security and the intuitive user experience they need to unlock the potential of true crypto ownership. 1inch protocols and APIs provide core infrastructure across the DeFi industry and beyond.
So if you’re someone who thinks big, moves fast and wants to make an impact right from day one, then get ready to join our industry-changing team.
Location: We prioritise candidates who are based in Dubai then consider those working remotely in one of our European Hub Locations (UK, Spain or Germany).
Your mission
1inch builds some of the most-used interfaces in DeFi — from our flagship swap aggregator to advanced trading tools, portfolio views and developer-facing pages. Our frontend engineers own these experiences end-to-end, ensuring they are fast, reliable and intuitive for millions of users across multiple chains.
We are building a talent pool of frontend engineers at mid and senior level. This is an evergreen posting: there is no single open role tied to it, but when approved positions arise you will already be in our pipeline.
What you’ll do
- Design, develop, and maintain frontend applications and shared UI components using Angular, RxJS, and TypeScript
- Build responsive, scalable, and high-performance web applications with strong usability and security standards
- Contribute to frontend architecture decisions, testing strategies, CI/CD workflows, and development standards
- Improve frontend reliability, maintainability, accessibility, and browser performance optimisation
- Collaborate closely with product, design, backend, and blockchain engineering teams to deliver seamless user experiences
- Participate in code reviews, testing workflows, and continuous improvement of frontend engineering practices
- Monitor frontend application performance and contribute to observability and debugging processes
- At senior level, lead architectural initiatives, mentor engineers, and drive frontend engineering standards across teams
Who you are
- Strong proficiency with Angular, RxJS, and TypeScript
- Solid understanding of modern web technologies including DOM, SCSS/CSS, HTTP, CORS, and CSP
- Experience working with frontend monitoring, testing, and CI/CD tooling such as Sentry and GitHub Actions
- Familiarity with Service Workers and browser performance optimisation techniques
- Experience writing unit and integration tests for frontend applications
- Strong communication skills and ability to work effectively within distributed engineering teams
- Professional frontend engineering experience building scalable web applications in production environments
- For senior-level candidates, experience designing frontend architectures, reusable component systems, and leading technical initiatives
Nice to haves
- Experience working with Ethereum, JSON-RPC, Solidity, smart contracts, or Web3 technologies
- Familiarity with Ethers.js, EIP-2612, and Automated Market Maker (AMM) protocols
- Experience building decentralised applications and blockchain-based user interfaces
- Backend exposure with technologies such as NestJS, Docker, or microservices
- Experience working in fast-paced startup, scale-up, or high-growth technology environments
