  • Senior-level experience with TypeScript in production environments.

  • Proven ability to deploy and manage scalable, production-ready services.

  • Strong understanding of software testing, CI/CD practices, and system reliability.

  • Excellent written and verbal communication in English.

  • Demonstrated curiosity and passion for Web3 and decentralized technologies.

Nice to Have

  • Experience with Rust, Golang, or Python.

  • Familiarity with cloud service providers (we mostly use AWS)AWS services and serverless architectures.

  • Experience with IaC such as Terraform.

  • Knowledge of running blockchain nodes or integrating with RPC endpoints.

  • Past work on monitoring systems (e.g., Prometheus, Grafana, custom alerts).

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.
