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 This is a hands-on engineering role focused on Layer 1 blockchain integration, core blockchain infrastructure components, wallet engineering, and custody related blockchain workflows. The role works in close partnership with Crypto Custody Lead Engineers and Crypto Security Engineers to ensure blockchain interactions are secure, reliable, observable, and production ready. This engineer operates at the intersection of blockchain protocol mechanics and institutional custody systems. Years of experience needed 5+ years, * Integrate Organization 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. ## 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) - [Inside Bitpanda's Tech Stack: Scaling a European Fintech Leader - Markus Dorner](https://www.wearedevelopers.com/videos/1979-inside-bitpanda-s-tech-stack-scaling-a-european-fintech-leader-markus-dorner) - [Developing the Backend with Stefan Lingler, CTO at Shpock](https://www.wearedevelopers.com/videos/100360-developing-the-backend-with-stefan-lingler-cto-at-shpock) - [Debugging in the Dark](https://www.wearedevelopers.com/videos/1658-debugging-in-the-dark) - [Solving Real-world Problems with Blockchain at Algorand - Brian Whippo](https://www.wearedevelopers.com/videos/1368-solving-real-world-problems-with-blockchain-at-algorand-brian-whippo) - [Develop a Blockchain Application in JavaScript with Lisk SDK](https://www.wearedevelopers.com/videos/188-develop-a-blockchain-application-in-javascript-with-lisk-sdk) ## 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) - [From Hype to Code: Real Blockchain Use Cases for Developers](https://www.wearedevelopers.com/magazine/620-from-hype-to-code-real-blockchain-use-cases-for-developers) - [Why Blockchain?
