Vos missions au quotidien
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.
Ce que l’on cherche
Experience: 5+ years in QA for distributed or multi-service systems.
Scripting: Strong scripting skills in Python and Bash within Linux environments.
Languages: Familiarity with Rust and TypeScript/JavaScript to work with our test frameworks and tooling.
Infrastructure: Hands-on experience with Docker/Kubernetes, CI/CD pipelines, and databases (PostgreSQL, Redis).
Observability: Experience using tools like Grafana, Prometheus, or OpenTelemetry to diagnose system health.
Mindset: You enjoy “breaking things” to make them stronger and have a developer-centric approach to quality.
Bonus Points
Experience with K6 or similar load-testing frameworks.
A background in software development.
Previous experience in blockchain or cryptography.
