• Work within Linux and shell environments to support scripting, scheduled jobs, cron processing, log reviews, and troubleshooting.
• Implement data validation, error handling, monitoring, and traceability controls.
• Troubleshoot pipeline failures, data discrepancies, performance issues, and integration defects.
• Collaborate with client, security, infrastructure, data engineering, and delivery teams.
• Communicate technical issues, risks, and recommendations clearly to technical and nontechnical stakeholders.
• Participate in Agile planning, status reporting, documentation, issue tracking, and cross-team coordination.

• Strong Python programming experience supporting data transformation, integration, automation, or pipeline operations.
• Experience parsing, transforming, and validating XML-based data.
• Experience working in Linux and shell environments, including scripting, scheduled jobs, cron, and log troubleshooting.
• Experience implementing data validation, error handling, pipeline monitoring, and production troubleshooting.
• Strong written and verbal communication skills.
• Ability to explain technical concepts clearly to clients and stakeholders.
• Ability to collaborate across security, infrastructure, engineering, and delivery teams.
• Self-motivated and proactive, with a positive and collaborative approach.
• U.S. citizenship is required.
• Must be willing and able to undergo a background investigation for a Public Trust suitability determination.

Preferred Qualifications

• Experience using Python as the primary language for data pipeline automation, transformation, monitoring, or production troubleshooting.
• Experience supporting Java-based applications, services, or integrations.
