# Job Description : Senior Blockchain Specialis t

## 1. Role Overview

As a Senior Blockchain Specialist, you will be the lead expert responsible for connecting our core financial infrastructure to a diverse set of public blockchain networks. You will take ownership of the integration, reliability, and security of all interactions with protocols like Bitcoin, Ethereum, and various stablecoin platforms (e.G., Circle).

This is a senior, hands-on role for a deep technical expert in blockchain protocols and infrastructure. Unlike a pure smart-contract developer, your focus will be on the critical bridge between our off-chain systems and the on-chain world. You will be responsible for everything from integrating with institutional custody APIs like Fireblocks to ensuring the faultless broadcasting and confirmation of transactions. Your expertise will be vital for the 24x7 Settlement Engine and the Lombard Lending platform, ensuring the integrity and security of our multi-asset operations.

## 2. Key Responsibilities

• Lead Blockchain Integration Architecture :
• Design and implement robust, scalable, and secure integrations with multiple L1 and L2 blockchains, including Bitcoin and EVM-based networks.
• Architect the systems responsible for monitoring on-chain events, managing transaction nonces, and calculating network fees.
• Master Custody and Wallet Infrastructure :
• Serve as the technical lead for integrating with our institutional custody provider (Fireblocks), orchestrating the creation of vaults, management of wallets, and automation of transaction signing policies.
• Design and oversee the operational security procedures for multi-signature (MPC) signing and key management.
• Build Protocol-Specific Services :
• Develop the backend services required to interact with specific on-chain logic, such as orchestrating multi-sig vault operations for the Lombard Lending engine's collateral management.
• Integrate with third-party stablecoin providers (e.G., Circle APIs for USDC) to automate minting, redemption, and payment flows.
• Ensure Data Integrity and Reliability :
• Build and maintain the data pipelines that reliably ingest transaction data, balances, and state changes from various blockchains into our off-chain ledgers.
• Implement robust error handling and reconciliation mechanisms to guard against chain reorgs and other network instabilities.
• Technical Mentorship :
• Provide expert guidance to other backend engineers on the nuances of blockchain interaction, transaction lifecycle management, and security best practices.
