Who You Are

You have 3+ years in QA with hands-on mobile testing experience. You test more than UI flows, you dig into the full stack, from SDK behavior on device to the backend systems behind it, using tools like Kreya and k9s to investigate services, and Kibana and Grafana to monitor system health. You're comfortable working with AWS services and understand how container orchestration ( Kubernetes, Docker), databases, and messaging systems ( Kafka, SQS) behave under real conditions.

What You’ll Do

• Own testing end-to-end: develop and execute comprehensive test strategies (regression, smoke, and beyond) and take ownership of post-release and post-implementation validation. You don’t just report bugs—you understand the system well enough to know why they happen.
• Test more than UI flows; investigate SDK behavior on device and backend systems behind it.
