Our people have the freedom to work from anywhere, along with the opportunity to grow — both professionally and personally — as part of a diverse, dedicated team.
We invite an Intermediate Software Engineer to join our dedicated blockchain-focused engineering team and develop new components for a large-scale fintech data platform serving private markets. In this role, you’ll build tools and applications deeply integrated with customer chains while contributing to the core blockchain capabilities of our platform.

- 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)
