-   2-4 years of blockchain development experience with smart contracts, dApps, on-chain logic, or blockchain services
-   Experience implementing and testing smart contracts in production or near-production environments
-   Solid understanding of blockchain fundamentals (transactions, wallets, gas models, on-chain state, contract interactions)
-   Experience implementing direct blockchain interactions (contract calls, event handling, transactions, and error recovery)
-   Experience with blockchain developer tooling or integration layers (SDKs, MCP servers, chain interaction APIs)
-   Strong engineering fundamentals (clean code, testing, and debugging distributed systems)
-   Experience with at least one backend programming language and API development
-   Experience with Docker and microservices-based applications
-   Strong communication and collaboration skills, including explaining technical trade-offs
-   Motivation to build deep blockchain expertise

**Desirable:**

-   Experience building backend services with Node.js/TypeScript or Python
-   Hands-on experience using AI-assisted development tools (Cursor, Claude Code)

🧩**Key responsibilities and your contribution**

In this role, you’ll join a blockchain-focused team building tools and applications deeply integrated with customer chains.

-   Develop and maintain smart contracts, on-chain logic, and services connecting platform components to blockchain capabilities

-   Collaborate with the team lead and senior engineers on technical design
-   Own feature implementation from design through testing and deployment
-   Participate in code reviews and write automated tests
-   Maintain quality across on-chain and off-chain components
-   Troubleshoot transaction failures, contract interaction issues, and integration bugs across distributed systems
-   Document implementation details and contribute to technical diagrams as needed
