Senior QA Engineer

At NOVACARD , we’re redefining how people use credit.

We are the first interest-free and no-annual-fee credit card in Mexico, designed to simplify personal finances and give users complete control – all from a mobile app. With NOVACARD, users can access up to $200,000 MXN in credit, only pay when they use it, and manage everything digitally in under 5 minutes. Our mission is to empower people to make smarter financial decisions by offering flexibility, transparency, and the freedom they need to reach their goals. Simple finances, big goals.

About the Role

We are looking for a Senior QA Engineer to ensure the quality, reliability, and seamless operation of our mobile and backend products. You will work across the full product flow — from a user action in the Android or iOS app through APIs, message queues, and databases — helping the team deliver secure and stable financial services to our customers.

This role is ideal for an experienced QA professional who enjoys investigating complex systems, identifying risks before release, and collaborating closely with product, development, analytics, and QA teams in a fast-paced fintech environment.

The role is fully remote, with occasional business trips if required.

Key Responsibilities

• Analyze new functionality, create test designs, and write and maintain test cases.
• Perform functional, integration, regression, and end-to-end testing.
• Test NOVACARD’s mobile applications on Android and iOS, including behavior across OS versions, screen resolutions, application updates, push notifications, and deeplinks.
• Validate complete user scenarios across the application, APIs, message queues, and databases — from user action to final data state.
• Prepare and maintain test data, including customers at different lifecycle stages, tariffs, credit limits, and product offers.
• Analyze test results, identify defects and risks, and provide clear, timely testing reports.
• Review requirements, identify cross-team dependencies, and align them with relevant teams before testing begins.
• Estimate testing effort, contribute to the maintenance and expansion of the regression test suite, and support release planning.
• Investigate logs, trace requests across services using correlation or trace IDs, and collaborate with developers to diagnose complex issues.
• Continuously improve QA processes, testing coverage, and product quality together with engineering and QA teams.
