We are hiring a Blockchain Developer to build data-driven systems and smart contracts that power risk analytics and allocation workflows in decentralized finance. You will work across on-chain and off-chain data, deliver secure Solidity contracts, and ship reliable services that integrate blockchain data with internal platforms. What You’ll Do • Extract, normalize, and store data from Ethereum, L2s such as Arbitrum and Solana, plus relevant protocols. • Design and implement secure Solidity/EVM contracts to enable data adapters, allocation validation, and rule evaluation. • Build and maintain services that integrate on-chain data to internal systems and external APIs. • Develop robust, testable logic for event ingestion, data orchestration and state transitions. • Implement access controls, pausability, monitoring, and on-chain and off-chain audit trails. • Collaborate with product and engineering teams to design resilient, auditable, and automated financial workflows. • Contribute to shared libraries and improve tooling for data ingestion, validation, and analysis. • Strong Python proficiency for data processing, backend services, and automation. • Extensive hands-on experience with Solidity, EVM tooling, and DeFi integrations. • Practical use of The Graph (subgraphs), Alchemy or Infura, Dune or Flipside, or custom indexing tools. • Understanding of decentralized data models, indexing, and event-driven architectures. • Track record of clean, maintainable, and secure code, with thorough tests and reviews. • Experience owning deliverables end-to-end and working in distributed, async teams. • Background in fintech, data engineering, or DeFi infrastructure. Nice to Have • Proficiency in C++ or Java for performance-sensitive components. • Experience with formal verification, bug bounty programs, or audit coordination. • Familiarity with time-series and relational data models. • Exposure to infrastructure basics such as containers and Infrastructure as Code, for example Docker and Terraform; knowledge of Kubernetes is a plus but not required. Soft Skills • Clear, structured communication.  • Attention to detail, strong ownership, ability to break down complex problems and deliver independently while being a reliable team player.  • Proactive, self-directed mindset suited to a fast-evolving technical environment.
