Strongly Preferred: * Experience with blockchain indexers, explorers, or chain analytics systems. * Familiarity with wallet architecture and blockchain signing workflows. * Exposure to crypto custody platforms or securitysensitive financial systems. * Strong debugging instincts in distributed, asynchronous environments. * Experience using AI tooling to support complex software development. ## Description * Integrate Client systems with existing Layer1 blockchains (e.g., Ethereumbased or other enterpriserelevant L1s). * Evaluate and, where appropriate, contribute to building or extending Layer1 capabilities to meet custody, scalability, or resiliency needs. * Understand chainlevel mechanics such as transaction lifecycle, finality, forks, reorgs, and event propagation. * Ensure blockchain integrations are reliable under stress conditions and production loads. Blockchain Infrastructure Components * Design and build core blockchain infrastructure services, including: * Indexers and event processors * Block explorers and observability tooling * Chain data services and APIs * Interoperability and crosschain integration components * Ensure blockchain data pipelines are accurate, performant, and auditable. * Support operational tooling required for troubleshooting, monitoring, and incident response. Wallet Architecture & Development * Contribute to wallet architecture and development, including: * Blockchainfacing wallet services * Transaction creation, signing workflows, and submission pipelines * Integration with custody key management systems (MPC, HSMs, signing services) * Ensure wallet implementations cleanly separate protocol logic, security controls, and business rules. * Partner closely with custody and security engineers to validate endtoend transaction flows. CustodyRelated Blockchain Workflows * Share responsibility for custodyrelated blockchain workflows, including: * Onchain transaction execution * Event monitoring and reconciliation * Chainspecific failure handling and recovery patterns * Help define safe patterns for interacting with smart contracts and token standards from custody platforms. * Ensure blockchain workflows align with custody policies, approvals, and risk controls. Engineering Rigor & AIAugmented Development * Apply modern engineering practices to build reliable, testable, and observable blockchain services. * Leverage GenAI and agentic AI tools to accelerate: * Protocol analysis * Code development and testing * Documentation and knowledge sharing * Maintain engineering rigor speed without sacrificing correctness or safety., * Wallet and transaction pipelines behave correctly across normal and edgecase chain conditions. * Custody systems interact with blockchains safely and consistently. * Incidents related to blockchain dependencies are well understood and quickly diagnosed. * This role establishes strong foundations for scalable digitalasset custody and tokenization platforms. ## Related Videos - [Pragmatic Blockchain Design Patterns: Integrating Blockchain into Business Processes](https://www.wearedevelopers.com/videos/1579-pragmatic-blockchain-design-patterns-integrating-blockchain-into-business-processes) - [The Memory Leak That Ate Our Cluster: A Postmortem](https://www.wearedevelopers.com/videos/2057-the-memory-leak-that-ate-our-cluster-a-postmortem) - [Developing the Backend with Stefan Lingler, CTO at Shpock](https://www.wearedevelopers.com/videos/100360-developing-the-backend-with-stefan-lingler-cto-at-shpock) - [Future-Proofing FinTech With Blockchain Technology](https://www.wearedevelopers.com/videos/808-future-proofing-fintech-with-blockchain-technology) - [How to Build for Decentralized Systems](https://www.wearedevelopers.com/videos/931-how-to-build-for-decentralized-systems) - [Build Your Blockchain Application in JavaScript](https://www.wearedevelopers.com/videos/49-build-your-blockchain-application-in-javascript) ## Related Articles - [7 tips on how to become a blockchain developer](https://www.wearedevelopers.com/magazine/53-7-tips-on-how-to-become-a-blockchain-developer) - [Why Blockchain?
