Job description:

Friends, we are looking for Middle/Senior Fullstack web3 developer on our projects.

About the project:

The project is a frameworkdesigner constructormodular library for building Web3 applications. Its main goal is to increase and speed up the adaptation of Web3 in the masses, and to give a simple and universal tool for creating Web3 applications to both developers ("low code mode") and non-technical specialists ("no code mode"). A good analogy for a Casimir-Web3 ligament may be a Wordpress-Web2 link. You can read more about the product here https ://casimir.deip.world/

Position requirements:

  • 3+ years (ideally 5+ years) of experience as a Full-Stack software engineer;
  • Strong knowledge of JavaScript and its execution environments (both server-side and client-side);
  • Experience with front-end JavaScript frameworks and libraries (Vue.js is a big plus);
  • Experience with messaging systems (Apache Kafka, RabbitMQ, etc.) and understand concepts like concurrency and transaction management;
  • Experience with establishing and managing relational and/or NoSQL databases (e.g. PostgreSQL, MongoDB);
  • Experience with the Docker and its orchestration tools (k8s, docker-compose);
  • Understanding of basic primitives in Web3 (DAO, NFT, FT etc.);
  • Understanding of fundamental principles in cryptography;
  • Be comfortable with the modern stack and common standarts in Web3 (web3.js, ERC-20, ERC-721, near-api-js, NEP-141, NEP-171, client-side private key management, etc.);
  • Writing extensive comments, documentation, design flow diagrams, and review PRs in English;
  • Working with our team to create tutorials and demonstrations that allow other developers to easily use/interact with the open-source components you develop;
  • English at B1+ (i.e. be able to keep all public conversations in English);
  • Strong organizational skills - ability to work full-time remotely with no supervision;
  • Responsibility.

Working conditions:

Location: Any country;

Format: outstaff, 5/2.

Attention: for applying for this position, mark "I found out about the vacancy through Jooby.dev".
