Archon Labs - Blockchain Developer
deCircle
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. #J-18808-Ljbffr
