What is a Web3 developer?

A Web3 Developer builds decentralized applications (dApps) that run on blockchain networks, utilizing smart contracts and protocols like Ethereum, Solana, or Polkadot. They work with technologies such as Solidity, Rust, and Web3.js to create secure, trustless applications. Web3 Developers focus on decentralization, cryptographic security, and interoperability while integrating blockchain with front-end and back-end systems. Their work is crucial in sectors like DeFi, NFTs, and DAOs, shaping the next generation of the internet.

What are the key skills and qualifications needed to thrive as a Web3 developer?

To thrive as a Web3 Developer, you need a solid foundation in blockchain technologies, smart contract development (particularly with Solidity or Rust), and decentralized application (dApp) design, often backed by a computer science degree or similar experience. Familiarity with tools such as Ethereum, Web3.js, Truffle, and relevant blockchain testnets is crucial, and industry certifications like Certified Blockchain Developer (CBD) can be advantageous. Strong problem-solving skills, adaptability, and effective communication are important soft skills for collaborating with cross-functional teams in a fast-evolving ecosystem. These competencies ensure that you can build secure, scalable decentralized solutions and effectively navigate the dynamic landscape of Web3 technology.

What are some common challenges Web3 developers face in their daily work?

Web3 Developers often encounter the challenge of rapidly changing technologies and standards in the blockchain space, which requires continual learning and adaptation. Security is a major concern, as smart contracts are immutable once deployed and can be vulnerable to exploits without thorough auditing. Developers also face complexities in integrating decentralized systems with traditional web infrastructure and ensuring a smooth user experience. Collaborative problem-solving with team members, including product managers and security auditors, is a routine part of the job to produce robust and compliant applications.

Job description

Discover your future at Citi
Working at Citi is far more than just a job. A career with us means joining a team of more than 230,000 dedicated people from around the globe. At Citi, you'll have the opportunity to grow your career, give back to your community and make a real impact.
Job Overview
Citi is seeking a passionate and skilled Digital Assets Web3 Blockchain 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
  • Integrate Web3 libraries and SDKs (e.g., Web3J, Web3JS, Ethers.js, Viem) into enterprise Java and/or Node.js backend services
  • Implement asynchronous, event-driven architectures to handle on-chain events, transaction lifecycle management, and blockchain state synchronization
  • Collaborate with architects and senior engineers to contribute to the design of scalable, secure, and resilient Web3 infrastructure
  • Participate in code reviews, providing and receiving constructive technical feedback to maintain high engineering standards
  • Support the integration of digital asset custody solutions, tokenization frameworks, and DeFi/TradFi bridging components
  • Contribute to technical documentation, including smart contract specifications, integration guides, and architecture notes
  • Stay current with the rapidly evolving Web3 ecosystem - tracking protocol upgrades, new token standards, Layer 2 solutions, and emerging tooling relevant to institutional use cases
  • Work within Agile/Scrum frameworks, participating in sprint planning, stand-ups, and retrospectives within a distributed global team
  • Help identify and resolve technical issues across the Web3 stack, escalating where appropriate to ensure delivery quality and timelines

Qualifications / Experience
  • Bachelor's degree in Computer Science, Engineering, or a related discipline; MS is a plus
  • 10 to 15 years of overall software engineering experience, with a strong backend development foundation
  • 3 to 5 years of hands-on experience in Web3 and blockchain application development, including smart contract development and blockchain protocol integration
  • 8 to 12 years of experience with backend development using Java/Spring, Node.js, or equivalent enterprise frameworks
  • Proficiency in smart contract development, including testing frameworks (Hardhat, Foundry, Truffle) and security best practices
  • Hands-on experience with Web3 libraries such as Web3J, Web3JS, Ethers.js, or Viem
  • Solid understanding of blockchain fundamentals - consensus mechanisms, transaction lifecycle, gas models, wallet infrastructure, and key management
  • Experience with token standards (ERC-20, ERC-721, ERC-1155, ERC-3525, or equivalent) and tokenization patterns
  • Familiarity with blockchain networks (Hyperledger Besu, Solana, Canton) is a strong plus
  • Experience with asynchronous programming, event-driven systems, and message queuing (Kafka, RabbitMQ, or equivalent)
  • Familiarity with DevOps practices, containerization (Docker, Kubernetes), and CI/CD pipelines
  • Understanding of cryptographic concepts - digital signatures, hashing, PKI, and secure key management - as applied to blockchain systems
  • Exposure to Layer 2 scaling solutions (Polygon, Optimism, zkSync, etc.) and cross-chain interoperability protocols is a plus
  • Experience in financial services or regulated industries is a plus
  • Familiarity with Agile/Scrum methodologies and distributed team collaboration tools

Competencies / Skills
  • Web3 Engineering Depth: Strong command of the Web3 technology stack - from smart contract development to on-chain/off-chain integration patterns and blockchain node interaction
  • Backend Engineering Fundamentals: Solid grounding in enterprise software engineering - API design, microservices, data structures, algorithms, and design patterns
  • Security Mindset: Awareness of common smart contract vulnerabilities (reentrancy, front-running, integer overflow, etc.) and best practices for secure on-chain development
  • Curiosity & Adaptability: Genuine enthusiasm for the Web3 ecosystem and the ability to rapidly learn and apply new protocols, standards, and tooling
  • Collaborative Spirit: Strong team player who communicates clearly and constructively with engineers, architects, and non-technical stakeholders
  • Delivery Orientation: Ability to manage personal delivery commitments, prioritize effectively, and produce high-quality output within sprint cycles
  • 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

  • Work on real-world, production-grade Web3 infrastructure at the scale and complexity of a global systemically important bank

  • 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
