Talent Pool - Software Engineer, Backend

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.

Your mission

1inch is one of the most widely used DeFi platforms, powering swaps, limit orders and liquidity tools across multiple chains. Our backend systems sit between users and the blockchain — routing transactions, aggregating liquidity, serving APIs at scale, and ensuring every operation is correct in a high-stakes financial environment.

We are building a talent pool of backend engineers at mid and senior level who want to help shape this infrastructure. 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.

• Contribute to observability, monitoring, incident response, and post-mortem processes

• Optimise backend services for performance, resilience, and operational efficiency

• Collaborate closely with product, blockchain, and infrastructure teams to deliver reliable distributed systems

• Participate in code reviews, testing workflows, and engineering best practices across the development lifecycle

• At senior level, own services end-to-end, define technical direction, and mentor other engineers

Who you are

• Professional experience building and operating backend systems in production environments

• Strong proficiency in Golang, Typescript or another backend/systems programming language with practical concurrency and performance knowledge

• Solid understanding of system design fundamentals including services, data flows, reliability, and maintainability

• Familiarity with blockchain platforms, smart contracts, transaction handling, and on-chain integrations

• Experience working with containerised services and modern deployment practices

• Strong problem-solving skills and ability to work effectively in fast-paced engineering environments

• Ability to balance technical quality, scalability, and operational reliability

• At senior level, experience owning projects end-to-end and contributing to architectural decision-making

Nice to haves

• Experience working with multiple blockchain networks or non-EVM ecosystems

• Familiarity with on-chain data indexing, observability tooling, or protocol debugging systems

1inch is an equal opportunity employer. We are committed to evaluating all candidates on the basis of their skills, experience, and potential — regardless of race, ethnicity, nationality, gender, age, religion, disability, or any other characteristic. We believe diverse teams build better products, and we welcome applications from all backgrounds.
