• Assist in defining and implementing data models within ServiceNow to support security operations and compliance initiatives.
• Work with third-party services for design review and optimal deployment configuration for enterprise cloud service utilization (relevant to integrations).
•  Design and implement data collection strategies for AppDynamics, ensuring comprehensive monitoring of application performance and infrastructure.
• Integrate AppDynamics data with Splunk for centralized visibility and correlation with other security and operational logs.
• Troubleshoot problematic service deployments and data flows, utilizing forensic tools and audit log review (relevant to monitoring and analysis).
• Develop methods to leverage AppDynamics data for identifying potential risks and optimizing application performance.
• General Data Engineering & Systems Expertise:
• Collaborate with mission partners to develop long-term enterprise audit solutions and normalize non-standard data sets.
• Engineer and maintain secure virtualized and cloud environments  for data platforms.
• Deploy and harden servers running Linux OS in accordance with CIS and other STIG guidelines.
• Develop runbooks, SOPs, and documentation for new processes and systems.
• Perform liaison duties between service providers and clients to bridge communication gaps and ensure adherence to SLAs.
• Review and evaluate data integrity and develop use cases for various data sets.
• Maintain system baselines and configuration management for data engineering tools.
• Contribute to the development of plans to safeguard data against unauthorized modification, destruction, or disclosure.
