About the Role

Zama is a leader in privacy-preserving cryptography. Our Blockchain division builds the secure infrastructure and SDKs that empower developers to build private applications.

As a Senior QA Engineer, you will be the guardian of reliability. You won't just find bugs; you will build the automated infrastructure that ensures our cryptographic primitives and blockchain services work flawlessly in the real world.

What You Will Do

• Build the Foundation: Design and maintain the end-to-end test platform, including deterministic environments and mocks for SDKs and APIs.

• Automate Everything: Create and integrate automated tests (Python/Bash) into our CI/CD pipelines (GitHub Actions) to ensure production readiness.

• Ensure Resilience: Beyond standard testing, you will conduct performance, stress, and chaos testing to see how our systems behave under pressure.

• Root Cause Analysis: Investigate failures deeply, diagnose the "why," and work with developers to fix issues and reduce test flakiness.

• Set the Standard: Define QA processes and templates that help the entire engineering team maintain high-quality unit and integration tests.
