Job description

We are seeking an experienced Senior Software Engineer with strong expertise in modern C++, Linux/Android, and AOSP/embedded Android development. This role requires an engineer who is comfortable working across the technology stack, from device-level native software and Android system services to backend services, telemetry, diagnostics, and data analysis.

The ideal candidate has strong engineering fundamentals, a quality-first mindset, and the ability to independently own complex technical problems from investigation through implementation, testing, deployment, and production support.

Key Responsibilities

• Design, develop, debug, and maintain C++17+ software on Linux and Android platforms.
• Develop and troubleshoot AOSP/embedded Android components, including native services, AIDL/Binder IPC, system properties, SELinux, and Android build systems.
• Build highly testable software using gtest/gmock, mocks, automation, and robust test strategies.
• Develop thread-safe applications involving concurrency, IPC, shared memory, and synchronization.
• Work across device and backend layers using C++, Hack/PHP, Python, Java, or Kotlin.
• Use SQL to analyze large datasets, including joins, aggregations, and percentile-based analysis.
• Create automation and engineering tools using Python and shell scripting.
• Investigate device logs, crashes, telemetry, performance issues, and production failures.
• Participate in code reviews, Git-based development, multi-branch releases, and production/on-call support.
• Own technical issues end-to-end and communicate progress, risks, and blockers proactively.
• Use AI-assisted development tools effectively for coding, testing, debugging, and engineering productivity.

Required Qualifications

• 10+ years of professional software development experience with modern C++ (C++17 or later).
• Strong development experience on Linux and/or Android.
• Hands-on experience with AOSP or embedded Android, including:
• Native services
• AIDL / Binder
• ADB
• System properties
• Strong unit-testing experience with gtest/gmock.
• Solid understanding of multithreading, mutexes, concurrency, IPC, and shared state.
• Backend programming experience in Hack/PHP, Python, Java, or Kotlin, with willingness to work regularly in Hack/PHP.
• Strong SQL and data-analysis skills.
• Experience with Python and shell scripting for automation.
• Proficiency with Git, code reviews, cherry-picks, and multi-branch development/release workflows.
• Strong written communication and ability to work independently.
• Ability to work primarily during Pacific business hours, including flexibility for on-call handoffs and launch‑critical activities.

Preferred Qualifications

• Telemetry, logging, or analytics pipeline experience, including protobuf, serialization, sampling, batching, and data uploads.
• Android/Linux crash diagnostics experience with tombstones, minidumps, symbolication, bug reports, or log collection.
• Backend development experience with Hack/PHP, Thrift/gRPC, or protobuf.
• Experience developing dashboards, monitoring, and alerting for event or time-series data.
• Experience supporting production services, including on‑call, incident triage, monitoring, and incident follow‑up.
• Android/iOS companion‑app or device‑to‑phone end‑to‑end automation experience.
• Experience with performance benchmarking, memory analysis, and resource‑constrained devices.
• Practical experience using AI coding tools to accelerate engineering and test development.

What We’re Looking For

A strong candidate will be a hands‑on, full‑stack systems engineer who can move comfortably between:

The engineer should demonstrate strong ownership, disciplined testing, proactive communication, and careful handling of sensitive devices, diagnostic, and user data.
