Our client is developing an AI-powered analytics layer on top of a network security data platform.
As a Senior Data Engineer on this engagement, you will design and deliver the core data infrastructure to derive security policies from operational technology network logs.
You will work with diverse, complex data exports from industrial security platforms - such as network monitoring systems - and transform them into a well-structured DynamoDB database. Once the data foundation is in place, you will connect it to AWS QuickSight to deliver interactive BI dashboards that give stakeholders immediate visibility into network behavior, security events, and policy gaps.
Responsibilities
- Design and implement DynamoDB databases to serve as the main analytical store for network and security log data
- Define table structures, partition keys, sort keys, and Integral Secondary Indexes for high-volume, time-series event data
- Optimize database performance and cost efficiency by leveraging DynamoDB features and establishing data archival strategies




- Build robust ETL pipelines to ingest data from Excel, CSV, and API feeds from network‑monitoring tools
- Cleanse, validate, normalize, and enrich raw security‑event data, handling inconsistent schemas and missing values
- Automate orchestration, scheduling, and error handling to ensure reliable pipeline execution and timely data delivery
- Connect DynamoDB to AWS QuickSight to create interactive dashboards and reports for security events and network traffic patterns
- Design and maintain QuickSight datasets, calculated fields, and visual analyses, iterating on dashboard design based on feedback
- Collaborate with cybersecurity experts, AI/Analytics Engineers, AI Architects, and stakeholders to translate business requirements into data architecture
- Produce clear technical documentation including schema definitions, data dictionaries, pipeline specifications, and operational runbooks

Requirements
- Minimum 3 years of experience in da
