About your Team:
The Enterprise Architecture organization is looking for a Senior Data Platform Engineer to join the team and help build the next generation of data infrastructure and AI-enabled workflows. In this role, you will design, build, and operate the scalable data lake platform, cloud infrastructure, and self-service tooling that internal teams across IBKR rely on to ingest, govern, and analyze data  will partner closely with internal development teams and IT leadership to architect platform solutions for diverse use cases across the organization, ranging from cloud-native data lakes and infrastructure as code to AI knowledge bases and advanced analytics.

Your work will focus on delivering robust, well-documented data platform capabilities and establishing best practices for data engineering and platform operations across the enterprise. What will be your responsibilities within IBKR:
Design, build, and operate the data lake platform and infrastructure, including S3-based storage and the AWS Glue data catalog, delivered as a governed, self-service platform that internal teams can build on Design and implement data governance and fine-grained access control across the platform using AWS Lake Formation, ensuring secure, least-privilege, and compliant access to data domains Automate infrastructure provisioning as code (e.g., Terraform), giving internal teams a repeatable, self-service path to stand up new platform resources Contribute to the GenAI knowledge base platform and Python-based services that internal teams use to build retrieval-augmented (RAG) and knowledge-driven AI applications Build or contribute to real-time streaming data pipelines (e.g., using Kafka) for event-driven analytics and data processing, as platform needs evolve Build and maintain scalable ETL/ELT pipelines and data crawlers to ingest data from various sources, transforming structured, semi-structured, and unstructured data (text, images, audio, video) for analytics and AI/ML workloads Monitor, troubleshoot, and continuously optimize the platform for performance, reliability, data quality, and cost efficiency, treating observability as a core platform capability Collaborate with internal development teams, data scientists, and stakeholders to understand requirements, architect platform solutions, and enable teams through clear standards and technical documentation Write clean, maintainable, well-tested code following software engineering and data engineering best practices What required skill’s you need:
Core Data Platform & Cloud Engineering 5+ years of hands-on data engineering or data platform experience, including building infrastructure, platforms, or tooling used by other engineering teams Strong experience with AWS cloud services, particularly S3, AWS Glue, Athena, and EMR

Experience with data governance and fine-grained access control, including AWS Lake Formation

Experience with infrastructure as code (e.g., Terraform) to build and manage cloud infrastructure and governance in a versioned, repeatable way Solid understanding of data lake architectures, cataloging, and partitioning strategies Proficiency in Python, with experience building and maintaining scalable ETL/ELT pipelines for data processing and automation

Experience with PySpark on EMR for large-scale data processing Strong SQL skills for data analysis and transformation

Experience with CI/CD practices, version control (Git), and containerization (Docker) AI/GenAI Platform Foundational understanding of GenAI concepts such as RAG architectures, vector databases, or semantic search, with willingness to build deeper hands-on…
