Job Overview

Citi is seeking a passionate and skilled Digital Assets Blockchain Web3 Engineer to join the Citi Integrated Digital Assets Platform (CIDAP) engineering team. This is a hands-on engineering role for a developer who is deeply enthusiastic about the intersection of decentralized technologies and institutional finance.

The successful candidate will contribute to the design, development, and deployment of Web3-native components and integrations that power Citi's digital asset infrastructure — spanning tokenization, smart contracts, on-chain settlement, and blockchain protocol integrations. You will work within a collaborative, globally distributed team of engineers, architects, and business technologists who are building the next generation of institutional digital finance capabilities.

We are looking for someone who brings strong Web3 engineering fundamentals, a curiosity for emerging blockchain ecosystems, and the ability to bridge decentralized technology patterns with enterprise-grade software standards.

Key Responsibilities

• Design, develop, and deploy Web3 components and integrations for Citi's Digital Asset Platform, including smart contracts, on-chain event listeners, wallet integrations, and blockchain protocol connectors
• Build and maintain backend services that interface with public and permissioned blockchain networks (e.g., Ethereum, Hyperledger Besu, Canton, Solana, or equivalent)
• Develop, test, and audit smart contracts written in Solidity or equivalent languages, ensuring security, correctness, and gas efficiency

Attention to Detail: Rigorous approach to testing, code quality, and documentation — particularly important given the immutable nature of on-chain deployments

Tooling Proficiency: Working knowledge of engineering tools including Git, Jira, Jenkins, Hardhat/Foundry, Docker, Helm, and observability platforms

Development Value

As a Blockchain Software Developer at Citi, you will be at the forefront of one of the most exciting and strategically significant technology domains in institutional finance. You will:

• Work on real-world, production-grade Web3 infrastructure at the scale and complexity of a global systemically important bank
• Gain deep exposure to institutional digital asset use cases — including tokenized securities, digital cash, on-chain settlement, and programmable finance
• Collaborate with world-class engineers, architects, and business leaders who are defining the future of digital finance at Citi
• Build expertise across both Web3-native and enterprise technology stacks, making you a uniquely versatile engineer in a rapidly growing field
• Access continuous learning opportunities, including emerging protocol research, industry conferences, and internal innovation programs
• Contribute to a platform with global reach and real commercial impact, with visibility across Citi's technology and business leadership
