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

Your mission

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.
