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 Data Ecosystem team is an important part of DRW’s Unified Platform (UP) organization, building the platform capabilities, managed infrastructure, and metadata management systems that underpin our common query layer and power thousands of batch and streaming pipelines delivering data across DRW.  As a Senior Data Engineer in our Unified Platform organization, you will design, build, and operate the data platform and managed services used by Traders, Quantitative Researchers, and Back-Office personnel. You will own engineering projects and service components, work directly with platform users to solve technical problems, and contribute to metadata management and governance capabilities. This is a hands-on role combining technical design ownership, software development, production support, and mentorship within the broader platform architecture.  Key Responsibilities  • Design, build, and operate managed platform services for data storage, distributed query execution, batch and streaming processing, and workload orchestration.  • Own technical designs and implementation decisions for services and components within the broader platform architecture, and lead their delivery from requirements through deployment and support.  • Automate provisioning, configuration, upgrades, and monitoring for managed services, reducing manual operations and improving consistency across deployments.  • Build and integrate metadata management tools, including data catalogs and lineage tracking, to help users discover datasets and understand their structure, ownership, and dependencies.  • Implement schema governance, data quality checks, access controls, and usage tracking in line with established policies, working with security and data stakeholders on technical requirements.  • Work with users of managed services to diagnose integration and performance issues, clarify technical requirements, and improve the services their workloads depend on.  • Improve the reliability and performance of managed services and shared processing infrastructure through observability, capacity management, and testing. Participate in production support and incident response for these services, resolving root causes and maintaining operational runbooks.  • Deliver platform upgrades and data migrations with appropriate validation and compatibility checks to protect downstream workloads.  • Lead design and code reviews for the services you own, document technical trade-offs, and contribute improvements to architectural patterns shared across the team.  • Mentor less experienced engineers through hands-on collaboration and feedback, promoting maintainable code, automated testing, and sound operational practices.  Required Qualifications  • 7+ years of experience working with modern data technologies and/or building data-intensive distributed systems.  • Expertise in Java and/or Python, with a proven ability to deliver high-quality, maintainable production software, and strong familiarity with SQL, Bash, and Linux environments.  • Experience building and operating managed data or infrastructure services offered to other teams, including operational automation and production support.  • Demonstrated ownership of engineering projects or service components from technical design through deployment and ongoing operation.  • Strong understanding of distributed systems trade-offs, including fault tolerance, concurrency, partitioning, and recovery from partial failures.  • Production experience with batch and streaming systems, including practical knowledge of state management, retries, replay, and data consistency.  • Experience with data processing or query technologies such as Flink, Spark, or ClickHouse, and the ability to evaluate their performance and operational trade-offs.  • Experience with multiple storage technologies, including object storage, relational or NoSQL databases, and event streaming systems such as Kafka. Familiarity with open table formats such as Iceberg or Delta Lake.  • Practical experience with data modeling, schema governance and evolution, and data quality controls. Experience integrating metadata management, data cataloging, or lineage capabilities into data systems.  • Experience with data formats and serialization systems such as Arrow, Parquet, Protobuf, or Avro.  • Experience with cloud-native data infrastructure, including Kubernetes, workflow orchestration, automated deployment, and production monitoring.  • Strong communication and problem-solving skills, with the ability to troubleshoot issues with platform users, collaborate across teams, prioritize competing work, and deliver in a fast-paced trading environment.  Desirable Qualifications  • Experience extending or scaling data catalogs or lineage tracking tools across multiple storage and compute technologies.  • Experience implementing access controls, usage tracking, or other governance capabilities in shared data environments.  • Familiarity with financial datasets and the needs of trading, quantitative research, or back-office users.  The annual base salary range for this position is $160,000 to $250,000 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.
