- Design and implement scalable, secure backend systems and APIs for interacting with both onchain protocols and offchain infrastructure.
- Collaborate with smart contract engineers to define interfaces and workflows between backend services and blockchain networks (EVM and non-EVM).
- Own integrations with custodians, identity/KYC providers, payments infrastructure, and third-party blockchain tooling.
- Support internal ops, investor services, and compliance teams with automation, auditability, and observability tools.
- Establish and enforce backend engineering standards, best practices, and security protocols across the stack.
- Participate in code reviews and architecture discussions, contributing to a culture of engineering excellence.
- 4+ years of backend software engineering experience, ideally with strong familiarity in modern languages such as Go (Golang), Python, C++, and TypeScript.
- Strong understanding of distributed systems, system design, and API development.
- Experience integrating with cloud infrastructure (AWS preferred), third-party services, and security/compliance-sensitive systems.
- Demonstrated interest in Web3 or DeFi—whether through professional experience or side projects.
- Familiarity with EVM-based blockchains and smart contract interactions is a plus, but not required.
- Comfort operating in a fast-moving startup environment with high ambiguity and high ownership.
- Located in a US time zone (PT–ET)
- Experience working with blockchain/Web3 data providers like The Graph, Alchemy, or Moralis.
- Prior work on tokenized asset platforms, DeFi protocols, or custodial/wallet infrastructure.
- Understanding of Solidity or other smart contract languages.
What does a back-end developer in Web3 do?
A back-end developer in web3 typically works on the server-side of a web application, using technologies that are specific to the decentralized web (also known as Web3-related)
This might involve building and maintaining the infrastructure that supports decentralized applications (dApps), or developing the underlying smart contracts and blockchain-based systems that power those dApps
In general, the goal of a back-end developer in web3 is to create the technologies and tools that enable users to interact with the decentralized web in a secure and seamless way.
