How does a Web3 JS developer typically collaborate with blockchain engineers and front-end teams during a project?

A Web3 JS developer often acts as a bridge between blockchain engineers, who build and maintain smart contracts, and front-end developers, who design user interfaces. They are responsible for integrating smart contract functionality into web applications, ensuring seamless communication between the blockchain and the user-facing components. Collaboration involves frequent code reviews, shared planning sessions, and troubleshooting issues that arise when connecting decentralized networks to web platforms. This role requires strong communication skills and the ability to translate complex blockchain logic into intuitive user experiences.

What are the key skills and qualifications needed to thrive as a Web3.js Developer, and why are they important?

To thrive as a Web3.js Developer, you need solid JavaScript programming skills, a strong understanding of blockchain concepts, and experience integrating decentralized applications (dApps) with Ethereum or similar networks. Familiarity with the Web3.js library, smart contract development (often using Solidity), and tools like Truffle or Hardhat is typically required. Strong problem-solving abilities, attention to detail, and effective communication set outstanding developers apart in this role. These skills ensure secure, scalable, and user-friendly blockchain applications that leverage the latest in decentralized technology.

What is Web3.js and what is it used for?

Web3.js is a collection of JavaScript libraries that allows developers to interact with the Ethereum blockchain. It enables web applications to read and write data to smart contracts, query blockchain data, and manage user accounts and transactions. Web3.js is commonly used to build decentralized applications (dApps) that run in users’ browsers and communicate with Ethereum nodes. It is a key tool for developers working in the blockchain and decentralized finance (DeFi) space.

Job description

DRW is a diversified trading firm with over 3 decades of experience bringing sophisticated technology and exceptional people together to operate in markets around the world. We value autonomy and the ability to quickly pivot to capture opportunities, so we operate using our own capital and trading at our own risk.
Headquartered in Chicago with offices throughout the U.S., Canada, Europe, and Asia, we trade a variety of asset classes including Fixed Income, ETFs, Equities, FX, Commodities and Energy across all major global markets. We have also leveraged our expertise and technology to expand into three non-traditional strategies: real estate, venture capital and cryptoassets.
We operate with respect, curiosity and open minds. The people who thrive here share our belief that it's not just what we do that matters-it's how we do it. DRW is a place of high expectations, integrity, innovation and a willingness to challenge consensus.
The UP-Trade Operations team builds software that enables DRW's trading operations teams to manage our growing DeFi footprint. A big part of what makes this work interesting is figuring out where DeFi instruments map to traditional financial concepts, where they extend them, and where they are something entirely new. We need engineers who can reason about these protocols financially, not just technically, and build reliable systems around them at institutional scale.
We work from high-level requirements where programmers are expected to gain an intimate understanding of the business. We strive for an environment where developers have the autonomy to pursue business solutions without arbitrary management constraints. We are a group of polyglots and technologists always seeking to find the right tool for each problem. Broadly, the development teams at DRW believe in rapid deployment and feedback, automated testing, and cohesive, transparent, lightly-coupled service architectures.
Problems You'll Work On:
  • Ingesting and normalizing data across multiple chains (Ethereum, Solana, and L2 rollups like Arbitrum) and custody platforms
  • Integrating with DeFi protocols -- AMMs, lending platforms, options vaults, staking providers -- to query on-chain state and track positions
  • Building services that bridge on-chain activity to off-chain reporting: token balances, transfers, margin positions, settlement, and fees across different ERC standards
  • Developing APIs and UIs that give traders and operations teams real-time visibility into DeFi positions and risk
  • Modeling DeFi instruments (liquidity pools, lending markets, perpetuals, yield products) alongside their traditional finance equivalents for unified reporting and risk

Responsibilities:
  • Building systems with a constant focus on testing, reliability, scalability, and maintainability
  • Designing, modeling, and programming in a variety of languages and technologies
  • Working on legacy code as well as greenfield development
  • Taking initiative and driving projects to completion
  • Learning and promoting new technologies with a focus on best practices
  • Providing on-call support as needed
  • Sometimes working alongside other developers on the same task

Professional Experience:
We expect strong engineering fundamentals, but what truly sets candidates apart is hands-on experience navigating the DeFi landscape.
DeFi & Blockchain:
  • Hands-on experience with EVM internals, smart contract ABIs, and libraries like ethers.js or web3.js
  • Familiarity with DeFi protocols: AMMs (Uniswap), lending (Compound), options/structured products, or staking
  • Understanding of multi-chain architectures -- L1s, L2 rollups, bridging, and cross-chain data challenges
  • Exposure to Solana or other non-EVM chains is a plus
  • Experience with oracle systems (Chainlink) or on-chain pricing
  • Ability to reason about DeFi protocols from a financial perspective, e.g. how different AMM designs affect pricing, how lending rates compare across protocols, or what distinguishes different stablecoin mechanisms

Engineering & Stack:
  • Multiple years of server-side development
  • Willingness to learn Clojure, one of the team's primary languages
  • Confident JVM knowledge
  • Working knowledge of Node.js/TypeScript
  • A solid understanding of micro-service architectures
  • Proficiency in domain-driven design and domain modeling
  • A good understanding of functional paradigms and type theory

Infrastructure & Tools:
  • Kubernetes, Docker, ArgoCD
  • PostgreSQL, Oracle, SQS, RabbitMQ
  • Linux, Ansible, Nginx, Git

The annual base salary range for this position is $130,000 to $225,000 depending on the candidate's experience, qualifications, and relevant skill set. The position is also eligible for an annual discretionary bonus. In addition, DRW offers a comprehensive suite of employee benefits including group medical, pharmacy, dental and vision insurance, 401k (with discretionary employer match), short and long-term disability, life and AD&D insurance, health savings accounts, and flexible spending accounts.
