- Experience with Express, NestJS or any other similar framework
- Flexible approach in regard to different programming languages/technologies
- Proven experience using any other stack (.NET/Go/Java/C++, etc.)

- Hands-on experience with Web3.js or Ethers.js for interacting with Ethereum or other EVM-compatible networks
- Understanding of smart contracts
- Familiarity with popular blockchains like Ethereum, Binance Smart Chain, or Layer 2 solutions
- Expertise in data structures, algorithms, and software design patterns
- Solid understanding of different software architectural patterns

- Experience with different kinds of ORMs

- Proficiency in writing unit tests, integration tests, and end-to-end tests
Will be a plus:
- Familiarity with DevOps practices and infrastructure as code tools
- Understanding of consensus algorithms, cryptographic principles, and decentralized applications (dApps)
We offer:
- Competitive compensation
- Social package (24 working days of annual leave, 5 paid sick days)
- Flexible working hours
- Challenging projects in diverse business domains and a variety of tech stacks
- Personal development and professional growth opportunities
- Work with talented, ambitious and family-feel teams
