Requirements:
- 4+ years of experience with server-side JS/TS
- Solid understanding of TypeScript, JavaScript fundamentals and internals
- 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.)
- Strong understanding of asynchronous programming, event-driven architecture, and non-blocking I/O
- 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 RDBMSes (MySQL/PostgreSQL)
- Experience in writing complex SQL queries and their optimization
- Experience with different kinds of ORMs
- Familiarity with Docker, containerization and orchestration tools
- Strong analytical skills with the ability to think critically and solve complex issues
- 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
