Original job description

Role Overview

We are looking for an ETL QA Engineer with strong experience in Databricks and PySpark, combined with hands-on exposure to AI-assisted development and prompt engineering. The ideal candidate will be responsible for validating large-scale data pipelines, ensuring data quality, and leveraging tools like GitHub Copilot, GitHub Actions/Runners, and AI agents to improve testing efficiency and coverage. You will also contribute to building and validating AI-powered knowledge bases.

Required Skills & Experience

Core Technical Skills
- Strong hands-on experience in Databricks (notebooks, jobs, clusters, Delta Lake, SQL).
- Expert-level PySpark skills, including transformations, actions, window functions, and optimization techniques.
- Solid understanding of ETL/ELT concepts, data warehousing, and data modeling (star/snowflake schemas, dimension/fact tables).
- Proven experience in data validation, data quality checks, and reconciliation techniques.
- Practical experience with GitHub, GitHub Copilot, and GitHub Actions/Runners for CI/CD pipelines.
AI & Prompt Engineering
- Experience crafting effective prompts for large language models (LLMs) for coding, testing, and documentation.
- Exposure to agent-based architectures or tools (e.g., workflow/agent frameworks that orchestrate multi-step AI tasks).
- Familiarity with AI-based tools for code analysis, test generation, or knowledge management.
Knowledge Base & Documentation
- Experience building AI-driven knowledge bases or documentation systems (e.g., using vector search, embeddings, or LLM-based retrieval).
- Strong documentation skills, with the ability to translate complex data/QA concepts into clear knowledge articles.
Testing & QA Practices
- Strong understanding of QA methodologies: test planning, test design, defect management, and regression testing.
- Experience with automated testing frameworks (Python-based testing libraries such as pytest, unittest, or similar).
- Familiarity with data quality tools/practices (e.g., validation rules, thresholds, anomaly detection).

Key Attributes

Strong analytical and problem-solving skills with a detail-oriented mindset.
Passion for data quality, automation, and continuous improvement.
Ability to work in an agile, fast-paced environment and collaborate across multiple teams like Business and operations team and AD team.
Curiosity and openness to adopting new AI tools and practices for QA.
