Talent Pool - Software Engineer, Backend (Typescript / Golang)

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.

This is not an active vacancy. Instead, we're building a network of exceptional backend engineers with a focus on Typescript or Golang and solid Web3 experience, who have successfully completed our interview process and are ready to join 1inch when new positions become available. Our engineering needs evolve rapidly, and we're always looking to connect with exceptional individuals who want to help shape the future of DeFi. We look for engineers with a high-agency, "Get Stuff Done" mindset and an unrelenting passion for decentralised innovation. We also embrace AI as a force multiplier for engineering, and value developers who thoughtfully leverage AI-powered tools to accelerate development, improve code quality, and solve complex technical challenges. Successful candidates who pass the interview process will join our Pre-Qualified Talent Network. This means that when a suitable position becomes available, you'll be among the first people we consider, allowing us to move quickly through the final hiring stages and, where appropriate, straight to an offer.
