About the role
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.
Requirements
- 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.
