Senior Software Engineer - DeFi

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 platformsIntegrating with DeFi protocols -- AMMs, lending platforms, options vaults, staking providers -- to query on-chain state and track positionsBuilding services that bridge on-chain activity to off-chain reporting: token balances, transfers, margin positions, settlement, and fees across different ERC standardsDeveloping APIs and UIs that give traders and operations teams real-time visibility into DeFi positions and riskModeling DeFi instruments (liquidity pools, lending markets, perpetuals, yield products) alongside their traditional finance equivalents for unified reporting and riskResponsibilities:Building systems with a constant focus on testing, reliability, scalability, and maintainabilityDesigning, modeling, and programming in a variety of languages and technologiesWorking on legacy code as well as greenfield developmentTaking initiative and driving projects to completionLearning and promoting new technologies with a focus on best practicesProviding on-call support as neededSometimes working alongside other developers on the same taskProfessional 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.jsFamiliarity with DeFi protocols: AMMs (Uniswap), lending (Compound), options/structured products, or stakingUnderstanding of multi-chain architectures -- L1s, L2 rollups, bridging, and cross-chain data challengesExposure to Solana or other non-EVM chains is a plusExperience with oracle systems (Chainlink) or on-chain pricingAbility 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 mechanismsEngineering & Stack:Multiple years of server-side developmentWillingness to learn Clojure, one of the team's primary languagesConfident JVM knowledgeWorking knowledge of Node.js/TypeScriptA solid understanding of micro-service architecturesProficiency in domain-driven design and domain modelingA good understanding of functional paradigms and type theoryInfrastructure & Tools:Kubernetes, Docker, ArgoCDPostgreSQL, Oracle, SQS, RabbitMQLinux, Ansible, Nginx, GitThe annual base salary range for this position is $130,000 to $225,000 depending on the candidate’s experience, qualifications, and relevant skill set.
