Zensar is looking for a Onsite QA at Toronto, Canada - French-speaking candidates are preferred
- We are looking for a technical Senior QA
- This is a backend-heavy engineering role focused on high-volume trade simulation and data integrity.
- You will use Python to build automation frameworks that simulate thousands of real-time trades, ensuring our systems can handle market volatility.
- You will use complex SQL to deep-dive into our databases, validating that every byte of data flowing through our AWS pipelines is accurate, compliant, and timely.
- If you enjoy breaking data pipelines, automating complex scenarios, and working in a high-stakes trading environment, this is the role for you.
Key Responsibilities
- Build Simulation Frameworks: Design and maintain Python-based automation scripts (using Pytest/Requests) to simulate thousands of real-time trades and stress-test our trading platforms.
- Data Pipeline Validation: Validate ETL/ELT processes within AWS. Ensure data flows correctly from ingestion to storage, identifying data loss or transformation errors.
- Deep-Dive Analysis: Execute advanced SQL queries against MySQL/Snowflake/Hive databases to verify data accuracy, consistency, and completeness across the Datalinx ecosystem.
- Performance Engineering: Identify bottlenecks in the data product lifecycle. Analyze how the system behaves under high load and work with developers to optimize performance.
- Root Cause Analysis: Go beyond "reporting bugs." Trace issues back to the specific service, API endpoint, or database procedure causing the failure.
The Tech Stack
- Language: Python (Heavy scripting, Pytest, Pandas, Requests).
- Database: SQL (MySQL, Snowflake, Hive, Athena).
- Cloud: AWS (S3, Data Pipelines, EC2, EMR, Lambda functions, REST APIs).
- Tools: GitHub, JIRA, Confluence
Must-Have Qualifications
- 5+ years in Software Quality Assurance with a specific focus on Data QA and Backend Automation.

- Advanced SQL Skills: You can write complex joins and window functions to validate large datasets without relying on a GUI.
- AWS & Cloud Data: Proven experience testing data pipelines and understanding how data moves through cloud infrastructure (AWS preferred).
- API Testing: Strong experience testing RESTful APIs and integrating them into automation suites.
- Performance Testing: Experience with load testing tools and strategies (simulating high-volume transactions).
- Operational Support: Support releases during off-business hours, when planned. Also providing support in case of adhoc issues to ensure system reliability.
Nice to Haves
- Capital Markets Experience: Understanding of equity markets, trade lifecycles, and financial instruments.
