Senior Test Automation Engineer - Enterprise Backup

As a Senior Test Automation Engineer Enterprise Backup, you will lead the design and maintenance of a reliable automated testing framework for backend services written in Go or Python. You will treat the testing environment as production code with a clear focus on reliability, isolation, and maintainability at every level. This deep engineering role involves ownership of layered testing, including unit, integration, and end-to-end suites, as well as managing complex dependencies to support the fast and confident release of critical services.

What you will be doing:

Go Ecosystem

• Mastery of the native Go testing stack (testing, t.Cleanup(), TestMain)
• Strong DI and mocking via interfaces
• Integration with Docker and Testcontainers Go SDK
• CLI and table-driven test validation
• Database testing (Postgres, Kafka, Redis)

Python Ecosystem

• Advanced use of Py test with fixtures and parameterization
• Deep knowledge of unit test mock and DI patterns
• Integration with Docker and Testcontainers Python SDK
• CLI and sub process validation
• Database testing (Postgres, Kafka, Redis)

Cross-platform implementation

• Develop backend services that run efficiently in Linux-based environments.
• Ensure system portability, performance, and reliability across platforms.

Collaboration & ownership

• Take full ownership of your projects as an individual contributor, from design to deployment.
• Collaborate with DevOps, QA, and product teams to ensure seamless integration and delivery.
• Contribute to improving internal processes and code quality standards.

What we expect from you:

• Build Clean Frameworks: Design the core testing architecture using principles like Dependency Injection (DI) to ensure tests are fast, modular, and fully isolated.
• Advanced Integration: Implement and manage Testcontainers to automatically spin up and tear down real external services (databases, storage systems) for high-fidelity, repeatable integration tests.
• Guarantee Stability: Enforce strict cleanup policies (using Go's t.Cleanup() or Pytest fixtures) to ensure all temporary resources are reliably removed after every test run.
• Full E2E Automation: Develop robust End-to-End (E2E) tests, including validating CLI tools, outputs, and exit codes from the perspective of a real user.
• Optimize and Enforce: Optimize the entire test workflow for speed and enforce high code coverage standards (80% or higher) within our CI/CD pipelines.
