What you’ll do:

As a QA Engineering Intern for the Customer Portals team, you will help ensure that our clients have a seamless and reliable experience when interacting with Zefr’s products. Success in this role involves identifying potential user-facing issues before they reach production and validating that the data displayed in our portals is accurate. You will play a vital role in the engineering ecosystem by bridging the gap between complex data processing and the final user interface, helping the team maintain high deployment velocity with confidence.

  • Build and Execute automated test cases to verify the functionality, usability, and visual integrity of customer-facing web applications.

  • Validate API responses to ensure the data being sent to our portals is accurate, structured correctly, and performing efficiently.

  • Perform data quality checks by writing Python scripts and SQL queries to compare the information displayed on the UI against the underlying database records.

  • Document clear, reproducible bug reports in our tracking system to help developers identify and resolve technical issues quickly.

  • Collaborate with senior QA engineers to maintain and extend automated UI test suites using Playwright framework.

  • Participate in agile ceremonies, including sprint planning and daily stand-ups, to understand feature requirements and provide input on testability.

  • Assist in regression testing during release cycles to ensure new updates do not negatively impact existing portal functionality.

What we’re looking for:
  • Education: Currently pursuing a Bachelor’s or Master’s degree in Computer Science, Information Technology, or a related technical field.

  • Experience: Previous internship experience or academic project work involving software testing, web development, or data analysis (0–1 years of experience).

  • Programming Skills: Foundational knowledge of Python or another scripting language, with an interest in learning automated testing frameworks (e.g., Selenium, Playwright, or PyTest).

  • Database Skills: Basic proficiency in SQL for data retrieval and verification.

  • Technical Familiarity: Understanding of how web applications work, including basic knowledge of HTML, CSS, and how browsers interact with APIs (JSON/REST).

  • Analytical Mindset: Strong attention to detail and a natural curiosity for "breaking" software to find edge cases.

  • Communication: Excellent written and verbal communication skills to effectively describe technical issues to cross-functional team members.

  • Professionalism: A proactive learner who takes initiative to ask questions and seeks to understand the "why" behind product features.

Compensation (for US based employees):

The anticipated compensation for this position is between $25 and $30 per hour. Within the range, individual pay is determined by factors such as job-related skills, experience, and relevant education or training.
