Description and Requirements

Lenovo is building the next generation of intelligent device experiences powered by Qira , our crossdevice Personal AI platform. We are hiring a CrossDevice OS System Architect to define the endtoend architecture of OS system components that span multiple operating systems - including Android, Linux, Windows, and RTOS - across Lenovo and Motorola devices.

This is a highimpact individual contributor role for a senior technologist responsible for shaping platform architecture, defining crossdevice system interfaces, and designing scalable, secure, highperformance system layers that unify experiences across phones, PCs, tablets, and IoT/embedded products.
The role operates at the intersection of OS design, HAL/middleware architecture, crossdevice orchestration, and systemlevel performance engineering , aligned with Lenovo's nextgen AI strategy.

Location: The preferred work locations are San Jose, CA or Chicago, IL.

What You'll Do

• Define multiOS system architecture for OS components that operate across Android, Linux, Windows, and RTOSbased platforms.
• Define crossOS system architecture to support ondevice AI and agentic orchestratio n, enabling efficient coordination between local intelligence, OS services, and device resources across multiple platforms.
• Architect HAL, middleware, and systemservice layers that provide consistent abstractions across heterogeneous devices and siliconvendor ecosystems.
• Design crossdevice system capabilities and interdevice communication models that support Qira's seamless AI experiences across Lenovo's device portfolio.
• Lead the creation of OSlevel interfaces, runtime components, and platform contracts that unify device capabilities and ensure longterm extensibility.
• Drive deep performance engineering , including latency reduction, memory optimization, power efficiency, and thermal tuning across multiple OS architectures.
• Collaborate with internal platform teams and external silicon partners to define requirements, debug interactions, and optimize system performance endtoend.
• Conduct complex crosslayer investigations across frameworks, native services, IPC paths, HAL boundaries, and kernel/driver interfaces .
• Create and maintain highquality architecture documentation, technical specifications, interface definitions, and design guidelines for internal engineering teams.
• Influence Lenovo's OS roadmap by providing thought leadership and architectural direction across device categories and OS environments.
• Serve as a technical mentor and architect for senior engineers, helping elevate systemdesign maturity across the organization (IC leadership role).

Basic Qualifications

• 12+ years of hands-on experience in OS level engineering, embedded systems, system architecture, HAL or middleware development across Android, Linux, Windows, or RTOS platforms.
• Bachelor's degree in Engineering is required.
• Deep expertise in framework system service middleware HAL driver interactions across multiple operating systems.
• Strong proficiency in C/C++ for embedded and systemlevel development; familiarity with platform languages such as Java/Kotlin, C#, Python, or Rust .
• Proven experience designing and shipping system components on consumer or embedded devices (phones, PCs, tablets, smart devices, IoT).
• Background in enabling AIdriven system features , sensor pipelines, or multimodal data flows across devices.
• Demonstrated mastery of system performance tuning , including profiling, memory optimization, scheduling behavior, and power/thermal management.
• Extensive experience leading crossOS, crossdevice, or multiplatform system architecture initiatives as a senior individual contributor.
• Strong communication skills and the ability to articulate complex architectural decisions to engineering leadership and crossfunctional teams.

Preferred Qualifications

• Experience architecting crossdevice frameworks, multiplatform system interfaces, or distributed runtime components.
• Master's Degree in Engineering is preferred.
• Deep familiarity with integration of silicon vendor technologies.
• Experience with modular or updatable OS components (Android APEX/Mainline, Linux modular systems, Windows system modules).
• Strong debugging capability for issues that span native services, IPC, HAL layers, kernel, and lowlevel drivers .
• Passion for system architecture, OSlevel craftsmanship, and building unified platform foundations that scale across heterogeneous device categories.

The base salary budgeted range for this position is $190K - $220K. Individuals may also be considered for bonus and/or commission.
