Engineer - Blockchain Platforms

We are seeking a Senior Engineer - Blockchain Platforms to build and integrate the blockchain infrastructure supporting digital asset custody and tokenization platforms. This hands-on role focuses on Layer-1 blockchain integration, core infrastructure services, wallet engineering, and custody-related blockchain workflows. The engineer will collaborate with custody and security teams to ensure blockchain interactions are secure, reliable, observable, and production-ready., 1. Integrate enterprise platforms with Layer-1 blockchains and evaluate protocols based on custody, scalability, security, and resilience requirements.

1. Design and build blockchain infrastructure services, including indexers, event processors, chain-data APIs, observability tools, and cross-chain components.
2. Develop wallet services and transaction pipelines covering transaction creation, signing, submission, monitoring, and reconciliation.
3. Integrate wallet services with MPC, HSM, key management, and signing platforms.
4. Design for chain-specific conditions such as finality, forks, reorganizations, network congestion, and transaction failures.
5. Develop safe patterns for interacting with smart contracts, token standards, and blockchain networks.
6. Ensure blockchain data pipelines and services are accurate, scalable, testable, observable, and auditable.
7. Support troubleshooting, incident response, failure recovery, and root-cause analysis across distributed blockchain environments.
8. Use generative and agentic AI tools to accelerate protocol analysis, development, testing, documentation, and knowledge sharing.
