Core Data Engineer

Flow Traders is looking for a Core Data Engineer to own the end-to-end lifecycle of our most fundamental data products, including our Security Master; our reconciled ETF Compositions; high-resolution historical market data; and records of our trades, orders, quotes, and inquiries. High-quality data is the cornerstone of Flow Traders' strategic direction - beyond reducing complexity and BAU for stakeholders across the organization, quality data is a key requirement for our growth of quantitative trading styles.
In this role you will craft and execute the blueprint for these products, leveraging our Data Platform to build and monitor automated pipelines which ensure that users across the organization have reliable data at their fingertips when they need it. Further, you will become an expert in these data sets, leveraging that knowledge to optimize our use of the data we have and explore new sources for additional value. Finally, you will constantly collaborate with teams across the organization to ensure that our in-house systems are designed with data in mind, streamline additional data-related workflows, and work with stakeholders to maximize the value they extract from our data.
As the architect and guardian of our most valuable data, you will have a unique opportunity to make your mark on Flow Traders. You will be accountable for delivering these data products at an exceptional level of quality, ensuring that they are not only timely and pristine, but powerful enough to drive Flow Traders' future growth. Ultimately, your work will deliver one of the most important building blocks to the firm's strategic growth for the years to come.
What you will do:

• Be accountable for timely and high-quality delivery of core data products to the rest of the organization
• Develop and own the end-to-end lifecycle of these data products: build and maintain pipelines, develop quality checks, correct day-to-day operational issues, and systematize/automate manual processing steps
• Define and manage project plans to assume ownership of these data products

• Create and refine a common data model (esp. identifiers, normalized schemas, use of master data) 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, 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:

• Excellent programming skills (any language, Python preferred)
• Working proficiency with Linux, SQL and relational/non-relational databases
• Demonstrated ability to work with large datasets and familiarity with big data solutions
• Experience with Airflow, Kafka, and GCP (esp. GKE, Dataproc, and Big Query) highly desired
• Experience with Spark, Polars, Pandas, Apache Beam, Apache NiFi a plus
• 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
• Able to balance individual stakeholder demands to preserve quality and wide applicability of data
• Organized and able to define, manage, and execute projects (often several in parallel) while effectively triaging operational concerns
• Primarily technical, but domain-literate (exposure to symbology, security reference/pricing data, ETF compositions, exchange market data)
