Role Description

As a QA Automation Lead for Data Engineering at Juniper Square, you will be the primary owner of data quality and reliability for your project. You are expected to drive the end-to-end data testing strategy, ensuring the integrity, accuracy, and performance of our data pipelines and analytical platforms, and oversee release readiness. You will collaborate closely with data engineering, product, and data science teams to help define and drive our manual and automated testing efforts. You must be detail-oriented, passionate about data accuracy, and a strong advocate for high-quality data products and the end-user experience.

What You'll Do

• Quality Roadmap & Planning: Partner with Data Engineering and Product leadership to define the data validation and automation strategy for data platform features and new architecture releases.
• Backend & Pipeline Testing: Design and execute complex test cases targeting backend data systems, focusing on data integrity, distributed systems logic, data transformation consistency, and asynchronous batch or stream processing.
• AI-Augmented Testing: Leverage AI-powered tools like Cursor or Augment to rapidly prototype, scaffold new test suites, diagnose failures, and generate advanced data validation test scenarios.
• Data Automation Excellence: Develop, maintain, and extend scalable data automation frameworks and data quality monitoring suites by leveraging LLMs.
• Governance & Standards: Establish and enforce data QA best practices, coding standards, and rigorous code review processes for the automation team. Foster a culture of technical excellence and proactive problem-solving.
• Advocate for Automation: Champion an automation-first approach to data quality, minimizing reliance on manual data reconciliation, and partner with data engineering to systematically decrease manual testing effort.

Qualifications

• Bachelor's degree in Computer Science, Data Engineering, or equivalent professional experience.
• 7–10 years in Software Quality Assurance, including demonstrated ability to lead end-to-end testing efforts across the full software and data lifecycle.
• Knowledge of relational databases and strong proficiency in SQL with the ability to write complex queries for data validation, reconciliation, and root cause analysis.
• Solid understanding of data engineering concepts including data pipelines, ETL/ELT workflows, data warehouse architecture, and OLAP technologies (e.g., Redshift, Snowflake, BigQuery, or equivalent).
• Strong proficiency in Python including the ability to read, understand, and debug data pipeline code.
• Proven experience in QA automation, including designing and implementing automated test frameworks, test suites, and CI/CD-integrated testing pipelines.
• Proactive in using AI-powered tools (e.g., Augment, Cursor, Gemini) to accelerate test authoring, assist in debugging automation scripts, and optimize data documentation workflows.
• Experience managing the full release cycle for data features, from scoping testing requirements to final "Go/No-Go" delivery decisions.
• Excellent analytical and problem-solving abilities, exceptional attention to detail, and the ability to work independently in fast-paced Agile development teams with minimal supervision.
• Strong written and verbal communication skills in English.

AI & LLM Testing Experience

• Proactively leverage AI tools (e.g., Cursor, Gemini) to accelerate test authoring, debugging, and maintenance of data automation frameworks.
