I’m looking for a highly experienced Senior SDET / Automation Engineer to help build a reliable end-to-end automation system for a large-scale Android device farm. This includes orchestrating multi-device and multi-box environments, managing ADB/TCP/OTG transitions, integrating with existing Java-based automation services, and ensuring the system performs consistently under real-world hardware conditions. The role requires someone with true engineering depth—not just scripting—who can diagnose, architect, and implement automation that is stable, scalable, and production-ready. Your first responsibility will be to investigate and understand the existing project structure, hardware behavior, device lifecycle flow, and current automation logic. You will identify the correct integration points, evaluate technical risks, and propose a clear approach for achieving a unified one-click startup process that prepares all devices reliably. This discovery phase is hands-on: you’ll explore real devices, read system logs, analyze current interactions, and determine where automation must be hardened or redesigned. Once the architecture is understood, you will work hourly on implementing the required pieces: multi-box detection, OTG sequencing, device registration stabilization, Java service integration, error handling, retries, and health checks. The goal is to create a robust automation layer that can control a large number of devices with zero manual steps. I’m looking for someone who writes clean, maintainable code, communicates clearly, and thinks like an engineer—not a script runner.
