This is a unique opportunity to directly impact the security, scalability, and resilience of our blockchain operations, working hands-on to integrate and build the core components that underpin our next-generation financial services. Your expertise will be crucial in translating complex blockchain mechanics into enterprise-grade solutions, driving innovation and ensuring the integrity of our custody and tokenization platforms., * 7+ years of professional software engineering experience. * Hands-on experience building or integrating blockchain or distributed ledger systems. * Strong understanding of Layer-1 blockchain protocols and transaction lifecycles. * Experience building backend services, APIs, and infrastructure components. * Proficiency in one or more languages such as Go, Java, Rust, Python, or similar. * Ability to work effectively across custody, security, and platform teams. Strongly Preferred Qualifications * Experience with blockchain indexers, explorers, or chain analytics systems. * Familiarity with wallet architecture and blockchain signing workflows. * Exposure to crypto custody platforms or security-sensitive financial systems. * Strong debugging instincts in distributed, asynchronous environments. * Experience using AI tooling to support complex software development. ## Description As a Senior Engineer, you will be a hands-on contributor, operating at the intersection of blockchain protocol mechanics and institutional custody systems. You will work closely with lead engineers and security experts to ensure all blockchain interactions are secure, reliable, observable, and production-ready. Your contributions will establish strong foundations for scalable digital-asset custody and tokenization platforms, ensuring predictable, observable, and resilient integrations. * Integrate institutional systems with existing Layer-1 blockchains, evaluating and extending capabilities to meet custody, scalability, and resiliency needs. * Deeply understand chain-level mechanics such as transaction lifecycle, finality, forks, reorgs, and event propagation to ensure reliable integrations under stress and production loads. * Design and build core blockchain infrastructure services, including indexers, event processors, block explorers, observability tooling, chain data services, APIs, and interoperability components. * Ensure blockchain data pipelines are accurate, performant, and auditable, supporting operational tooling for troubleshooting, monitoring, and incident response. * Contribute to wallet architecture and development, focusing on blockchain-facing wallet services, transaction creation, signing workflows, and submission pipelines. * Integrate with custody key management systems (MPC, HSMs, signing services), ensuring clean separation of protocol logic, security controls, and business rules. * Partner closely with custody and security engineers to validate end-to-end transaction flows and ensure wallet and transaction pipelines behave correctly across normal and edge-case chain conditions. * Share responsibility for custody-related blockchain workflows, including on-chain transaction execution, event monitoring, reconciliation, and chain-specific failure handling and recovery patterns. * Help define safe patterns for interacting with smart contracts and token standards from custody platforms, ensuring workflows align with custody policies, approvals, and risk controls. * Apply modern engineering practices to build reliable, testable, and observable blockchain services, leveraging AI tools to accelerate protocol analysis, code development, testing, documentation, and knowledge sharing while maintaining engineering rigor., * Wallet and transaction pipelines behave correctly across normal and edge-case chain conditions. * Custody systems interact with blockchains safely and consistently. * Incidents related to blockchain dependencies are well understood and quickly diagnosed. ## 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) - [Blockchain Beyond Crypto: Technology Unlocking Opportunities across Various Industries](https://www.wearedevelopers.com/videos/998-blockchain-beyond-crypto-technology-unlocking-opportunities-across-various-industries) - [Future-Proofing FinTech With Blockchain Technology](https://www.wearedevelopers.com/videos/808-future-proofing-fintech-with-blockchain-technology) ## 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?
