How will you CONTRIBUTE and GROW?

Pipeline & ETL Management: Own and manage the Google Apps Script-based CI Portfolio Library. Ensure the automated extraction, transformation, and loading (ETL) of monthly reporting data from project templates runs seamlessly via automated, time-based triggers without human intervention.

Data Governance & Lifecycle: Enforce strict data governance and structural integrity by leveraging validation flags (Hub_Validated, CIG_Validated) and auditing automated modification logs. Manage system performance by routing closed project data into cold-storage Azure containers (portfolio-archive) to avoid Google Sheets cell limits.

Access Control & Security Architecture: Maintain granular Row-Level Security (RLS) mappings that tie Azure User Principal Names (UPN) to specific data visibility dimensions. Proactively manage backend Google Workspace file permissions to prevent automated script execution failures.

System Maintenance & Stabilization: Monitor local error logs to diagnose and resolve Apps Script runtime issues, frozen UI popups, and Azure API connection drops. Manually manage system safety locks (e.g., clearing stalled execution timestamps) and keep hardcoded environment parameters (email alerts, Daylight Savings Time arrays) up to date.

Are you a match?

Advanced Workaround Engineering: Ability to design, implement, and maintain "chained trigger" methodologies to bypass strict platform limitations (such as Google's 6-minute execution limit) and optimize memory constraints when handling massive datasets via getDataRange().getValues().

Operational Risk & Continuity Management: Competency in managing trigger ownership transfers smoothly during personnel transitions to avoid system-wide operational outages.

Precision Diagnostics & Troubleshooting.

Data Transformation Execution: Ability to dynamically map named ranges, transform complex multi-dimensional arrays into flat, CSV-ready records, and execute highly accurate data reconciliation engines

Education: Bachelor’s Degree or equivalence in work experience. Discipline: Preferably Computer Science, Information Technology, or Data Engineering, alternatively Software Engineering or/and Business Analytics.

Work Experience: 3-5 years.

Foreign Language: English, others desirable. Level required: Fluent.
