Role Responsibilities

• Architect, build, and optimize scalable ETL/ELT pipelines using Palantir Pipeline Builder and advanced Python.
• Manage end-to-end movement and ingestion of structured and unstructured data into local and enterprise storage repositories using compliant, approved methods.
• Create one-time extraction scripts and automated recurring ingestion pipelines from heterogeneous data sources.
• Transform raw, disparate datasets into clean, well-governed enterprise and standalone data models suitable for production analytics.
• Build direct integrations with external systems via RESTful APIs, parsing responses into clean, typed data objects.
• Design, build, and configure mission-focused user interfaces within Palantir Workshop.
• Write, test, and deploy custom application functions using TypeScript to extend interface capabilities and user interactions.
• Develop custom tools, reusable code libraries, and micro-services to automate operational data engineering workflows.
• Act as a Tier 2 escalation point to diagnose, triage, and remediate technical data issues reported by end-users.
• Convert customer feedback and operational pain points into detailed functional and technical requirements, including clear downstream impacts to the environment.
• Collaborate with Data Scientists, analysts, and project stakeholders to define data schemas, exploration formats, and analytical transformation rules.
• Perform operations and maintenance (O&M), performance tuning, and feature enhancements on existing data pipelines and codebases.
• Participate in peer code reviews, architectural brainstorming, and solution design sessions.
• Create and maintain engineering documentation, including ETL field-level mappings, code location references, user guides, and access protocols.
