Archon is seeking a highly motivated, detail-oriented Senior Blockchain Developer. If you're passionate about emerging technologies, particularly AI, and you thrive in fast-paced, dynamic startup environments, you will be positioned to make a significant impact in a fast-evolving industry.

About the Role

We are hiring a Senior Blockchain Developer to build data-driven systems and smart contracts that power risk analytics and allocation workflows in decentralized finance.

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.

What You bring

• 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.

• 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.

Why Join Us?

You will play a pivotal role in shaping and building our product foundation as we operate at the intersection of AI and DeFi. We value initiative, integrity, and a self-starter mentality, and we are committed to fostering a culture where our teams drive the creation of cutting-edge technology.
