Core Data Engineer - Real Time

Join Flow Traders as a Core Data Engineer with a Focus on Real-Time Analytics

Flow Traders is looking for a Core Data Engineer with a distinct focus on real-time analytics solutions. In this role, you will be responsible for owning the end-to-end lifecycle of our most critical data products that bring low-latency analytical capabilities to end users. This is a unique opportunity to join a leading proprietary trading firm with an entrepreneurial and innovative culture at the heart of its business. We value quick-witted, creative minds and challenge them to make full use of their capacities.

You will be the architect and executor of the blueprint for these real-time data products, enhancing our Data Platform to develop and monitor automated pipelines. Your goal is to ensure that stakeholders across the organization have immediate access to reliable data whenever it is needed. You will further become an expert in these dynamic data sets—drawing from sources such as market data, network traffic and application logs—to optimize their use and explore additional sources for unlocking value in real time.

As the steward of our most vital real-time data products, you will be uniquely positioned to influence Flow Traders’ operations. Your accountability will lie in delivering these data products at exceptional quality—with a focus on low latency—to drive future growth. Ultimately, your work will provide substantial, real-time benefits felt across all divisions daily, laying one of the most crucial foundations for the firm’s strategic expansion in the years ahead.

What you will do:

• Be accountable for timely and high-quality delivery of core data products to the rest of the organization: Market Data, Trades/Orders/Quotes/Inquiries, Application Logs with a specific focus on low-latency analytics
• Develop and own the end-to-end lifecycle of these data products: build and maintain pipelines, develop quality checks, correct day-to-day issues, and systematize/automate manual processing steps
• Define and manage project plans to assume ownership of these data products
• Create and refine a common processing model (esp. fast vs slow path, use of alternative T3 solutions) across these data products
• Investigate currently available sources of data and ensure that Flow extracts maximum information and value from them
• Explore, evaluate, and onboard additional sources of available data (both independently and at the request of stakeholders)
• Work closely with other teams to: automate existing workflows, develop real-time capabilities as platform offering, ensure pipelines leverage standard Flow technologies, provide guidance on data-related architecture/design topics, ensure licensing and access control are appropriate

What you need to succeed:

• Organized with strong attention to detail and quality
• Innately driven to generalize, systematize, and automate
• Strong interpersonal skills, works very well with both technical and non-technical stakeholders
• Ability to balance individual stakeholder requirements in order to preserve quality and wide applicability of data
• Ability to define, manage, and execute projects (often several in parallel) while effectively triaging operational concerns
• Primarily technical, but domain-literate (exchange market data, network traffic data, security reference/pricing data, ETF compositions, application log data; should not be solely exposed to Flow conventions)
• Domain expertise a huge plus (but not strictly necessary)
• Excellent programming skills (any language, Python preferred)
• Working proficiency with Linux, SQL and relational databases, and version control systems
• Proven experience with real-time OLAP databases like ClickHouse, Apache Pinot, StarRocks required
• Experience with Airflow, Kafka, and GCP (esp. GKE, Dataproc, and Big Query) highly desired
• Experience with Pandas, Spark, Apache Beam, Apache NiFi a plus
