- Build resilience and chaos testing capabilities, including fault injection, network partition and latency simulation, pod and node failure scenarios, dependency degradation, and automated recovery verification.
- Improve test-suite reliability through flake detection and quarantine, test impact analysis, selective execution, parallelization, and reduced CI wall time.
- Build observability into the testing layer, including coverage reporting, test-health dashboards, failure-triage tooling, and signals identifying under-tested code.
- Create project templates and shared libraries so new services start with complete testing setups.

- Experience designing integration-test infrastructure for distributed systems, including ephemeral-environment provisioning and dependency management.
- Practical experience with load and performance-testing tools such as **k6**, **Locust**, **Vegeta**, **JMeter**, or **Gatling**.
- Solid **Kubernetes** and **Docker** fundamentals.
- Advanced understanding of **CI/CD** and large-scale test-suite optimization.
- A track record of measurably improving testing practices and culture on an engineering team.
- Comfort working independently on ambiguous, high-impact infrastructure challenges.
