Android Automation Engineer (ADB / AccessibilityService)

We operate a fleet of company-owned Android devices that run automated workflows: capturing notifications, reading on-screen state from apps and pushing structured events into our backend. We are looking for an engineer who lives inside the Android runtime rather than on top of it, and who can keep a large device fleet running reliably without babysitting. This is not a standard app development role. There is no design handoff and very little UI work. The job is making Android do things it was not really built to do, at scale, and keeping it stable across OEMs and OS versions. What you will own Build and maintain an AccessibilityService that traverses node trees across third-party apps and emits reliable, structured events Build and maintain a NotificationListenerService that captures, parses and deduplicates notifications across apps Write and maintain versioned selector maps so that a UI change in a target app degrades gracefully instead of breaking the fleet silently Manage a fleet of 50 to 200 physical devices over ADB: provisioning, health checks, remote restarts, log collection, session recovery Keep services alive under Doze, battery optimisation and aggressive OEM process killers (Xiaomi, Oppo, Vivo, Samsung) Build the on-device data pipeline: local buffering, dedupe, idempotent delivery, retry, backpressure when the network is unavailable Own observability: per-device heartbeats, capture success rates, alerting when a device silently stops reporting
