About this role
Job Requirements At Quest Global, it’s not just what we do but how and why we do it that makes us different. With over 25 years as an engineering services provider, we believe in the power of doing things differently to make the impossible possible. Our people are driven by the desire to make the world a better place—to make a positive difference that contributes to a brighter future. We bring together technologies and industries, alongside the contributions of diverse individuals who are empowered by an intentional workplace culture, to solve problems better and faster. Position Overview We are seeking a highly skilled Senior Embedded Systems Engineer to lead the hardware bring-up and low-level software enablement of our next-generation Augmented Reality (AR) platform. In this role, you will be at the absolute forefront of wearable computing, bridging the gap between cutting-edge silicon and advanced spatial computing frameworks. Your primary responsibility will be the foundational bring-up of our AR hardware platform using Android XR. You will architect, develop, and debug kernel-space drivers, optimize critical display pipelines, and ensure seamless communication across high-speed interfaces like MIPI and QSPI. If you thrive on solving complex low-level engineering challenges to make immersive hardware a commercial reality, we want to talk to you. Core Responsibilities Platform Bring-up: Lead the low-level software bring-up of advanced AR platforms using the Android XR operating system on Qualcomm Snapdragon architecture. Driver Development: Architect and write robust Linux/Android kernel-space display drivers utilizing the DRM/KMS framework. Subsystem Integration: Configure and optimize the Android display subsystem (SurfaceFlinger, Hardware Composer) to meet strict AR latency and frame-rate targets. Interface Enablement: Implement, tune, and validate high-speed protocols including MIPI DSI and QSPI for micro-display panels and peripherals. Hardware/Software Debugging: Collaborate closely with the hardware engineering team to isolate and resolve signal integrity issues, power sequencing anomalies, and bus protocol bugs. Required Technical Skills Qualcomm Ecosystem: Direct, hands-on experience with Qualcomm Snapdragon processors, with a strong preference for dedicated wearable/spatial computing chipsets (e.g., AR1, XR2 Series). Display Protocols & Interfaces: Expert-level knowledge of MIPI DSI and QSPI communication interfaces, including timing configurations and register-level tuning. Android & Linux Kernel: Proven experience in writing Android/Linux kernel drivers, particularly within the display framework (DRM/KMS), alongside deep familiarity with SurfaceFlinger. Programming Languages: Mastery of C and C++ for low-level embedded software, system-level development, and RTOS environments. Lab Equipment & Diagnostics: Proficient with hardware debugging tools, including oscilloscopes, logic analyzers, and MIPI protocol analyzers to troubleshoot physical layer and protocol-level anomalies. Good to Have (Nice to Have) Familiarity with Qualcomm proprietary development, flashing, and diagnostics tools (QPST, QFIL). Experience with cutting-edge micro-display technologies (Micro-LED, Micro-OLED, or optical waveguides). Deep understanding of strict power management, dynamic voltage scaling, and thermal optimization for ultra-compact, wearable form factors. Experience implementing or optimizing low-latency AR pipelines (e.g., asynchronous time warp, foveated rendering, or late-stage reprojection). We are known for our extraordinary people who make the impossible possible every day. Questians are driven by hunger, humility, and aspiration. We believe that our company culture is the key to our ability to make a true difference in every industry we reach. Our teams regularly invest time and dedicated effort into internal culture work, ensuring that all voices are heard. We wholeheartedly believe in the diversity of thought that comes with fostering a culture rooted in respect, where everyone belongs, is valued, and feels inspired to share their ideas. We know embracing our unique differences makes us better, and that solving the worlds hardest engineering problems requires diverse ideas, perspectives, and backgrounds. We shine the brightest when we tap into the many dimensions that thrive across over 21,000 difference-makers in our workplace.
