Design, build, and maintain an Android observability SDK used by external developers in production at scale
Work on crash capture (JVM and NDK), ANR detection, performance tracing, and session orchestration
Develop and maintain native (C/C++) components including signal handling and JNI bridges
Evolve the SDK’s OpenTelemetry integration, spans, traces, and distributed tracing via W3C Traceparent
Build reliable mechanisms for offline storage, batching, retries, and telemetry delivery
Optimize for minimal SDK overhead: startup time, memory footprint, thread usage, and binary size
Own API surface design, binary compatibility, and versioning for a public SDK
Debug complex issues across devices, OS versions, OEMs, and customer environments
Contribute to architectural decisions across a modular SDK codebase
Establish best practices for testing, release safety, and code quality
Partner with cross-platform SDK teams (React Native, Flutter, Unity) to maintain internal bridge interfaces and ensure native changes do not break downstream consumers

Requirements

Strong proficiency in Kotlin, with solid working knowledge of Java
Deep understanding of Android runtime fundamentals: lifecycle, threading/Looper, memory, startup behavior
Experience working with native code (C/C++) on Android (NDK / JNI)
Track record building or maintaining SDKs, libraries, or developer-facing platforms
Experience using Git and modern CI/CD workflows
Experience optimizing for performance and reliability
Comfort debugging issues in production mobile environments
Openness to AI-augmented engineering workflows
Strong written and verbal communication skills, especially when discussing technical tradeoffs.
Experience with Android Gradle Plugin internals, custom Lint rules, or bytecode instrumentation (bonus points).
Open-source contributions (bonus points).
Experience designing and evolving public APIs (bonus points).
Experience maintaining backward compatibility (bonus points).
Experience optimizing startup impact, memory footprint, or runtime overhead (bonus points).
Exposure to cross-platform frameworks (React Native, Flutter, Unity), particularly understanding how native SDK changes ripple through those ecosystems (bonus points).
Familiarity with modern Android tooling/ecosystem trends (bonus points).
