The Role

As Nex’s Senior Embedded Software / AOSP Engineer, you bring Nex Playground to life. Your OS and firmware run on millions of devices, turning family living rooms into playgrounds where body motion, software, and on-device AI come together as one experience. You will lead the bringup of new platforms and hardware, and craft the HAL and framework layers that fuse our games, system maps, peripherals, and CV/ML pipelines with the silicon beneath.

You will architect the OS and own the full stack — SoC, GPU, NPU, Camera, ISP, WiFi, Bluetooth, HDMI, and power — squeezing best-in-class performance out of consumer-grade hardware. You will champion stability and security end-to-end, from a hardened boot chain to deep-stack profiling and disciplined root-cause analysis of field issues. As a technical anchor for the platform, you will help shape Nex’s hardware roadmap and the future products that millions will play on next. You’ll report to the Director of Hardware Engineering.

The Mindset

You build technology that improves people’s lives — especially where the physical and digital worlds meet. You live at the boundary of software and hardware, with deep instincts for how systems behave from the boot loader up. You chase root causes, not symptoms, and take pride in products that hold up at scale. You raise the bar for the systems and the people around you.

What You’ll Do

• Bring up new platforms and hardware, and optimize Playground’s AOSP-based OS across SoC, GPU, NPU, Camera, ISP, WiFi, Bluetooth, HDMI, and power for best-in-class performance.
• Design and implement system APIs, HAL, and framework layers in close partnership with the app, game, and CV/ML teams.
• Tune state-of-the-art image processing, CV, and ML pipelines to run efficiently on-device.
• Own system security end-to-end — harden the boot and verification chain, manage keys, and keep security patches current.
• Profile and debug deep into the stack with tools like perfetto, systrace, tcpdump, and Arm Mobile Studio, and drive field issues to root cause.
• Partner with SoC vendors and ODM / JDM partners on BSP drops, escalations, and silicon-level issues.
• Support manufacturing and factory operations — device provisioning, calibration data, key storage, and factory test images.

Must Have

• 5+ years building embedded system software.
• Hands-on experience across multiple AOSP versions, including BSP and SoC bringup.
• Working knowledge of the AOSP build system and release tooling.
• Track record shipping massively deployed embedded products.
• Deep knowledge of Android and Linux internals — kernel, device drivers, HAL, multi-processing, SELinux, verified boot, and performance optimization.
• Proficiency in low-level system debugging.
• Proficiency in C, C++, and Python.
• Good English communication.

Nice to Have

• Experience with TV, set-top-box, video conferencing, or gaming platforms.
• Domain knowledge of cameras, ISPs, and image processing pipelines.
• Domain knowledge of NPUs and deploying ML at the edge.
• Domain knowledge of Arm Cortex CPUs and Mali GPUs.
• Depth in the connectivity stack — WiFi supplicant, Bluetooth, and HID / controller pairing for peripherals.
• Hands-on experience with SoC vendor platforms such as Amlogic, Rockchip, MediaTek, or Qualcomm.
• Open-source contributions to the Linux kernel, AOSP, or related projects.

The Role

We’re looking for a QA Engineer who loves games, sweats the details, and enjoys learning new technology. Motion-based QA is different from traditional game QA: you’ll test with your whole body in real-world environments (lighting, room sizes, player heights, 1–4 players, etc.). Prior motion-gaming experience is not required—strong QA fundamentals and a learning mindset are.

What You'll Do

• Create and execute test plans and test cases for motion-based games and the Nex Playground experience.
• Validate core player experience for living-room play: onboarding, clarity, responsiveness, and “is this fun and understandable?”
• Test motion-game fundamentals such as responsiveness/latency, recognition consistency, occlusion handling, and edge cases.
• Perform functional, usability, regression, localization, and device/compatibility testing across the product surface area.
• Write excellent bug reports with clear repro steps, expected vs. actual results, environment details, and short video captures when helpful.
• Collaborate cross-functionally: clarify requirements, ask good questions, and flag risk areas early.

What We're Looking For

• 1–2 years of experience in IT or the game industry (or equivalent hands-on experience).
• Strong understanding of QA methodologies, tools, and processes.
• Excellent analytical and problem-solving skills.
• Strong attention to detail and a commitment to quality.
• Good communication and teamwork skills.
• Ability to work independently and manage multiple tasks simultaneously.
• Good command of written and spoken English.
• Hands-on comfort with hardware and TV setups, including basic troubleshooting (network, setup flows, updates)
• Willingness to perform physical movements during testing and appear in internal test recordings.
• A genuine interest in games and player experience—especially party/family-friendly titles.

Nice to Have

• Cantonese and/or Mandarin fluency
• Experience testing camera-based, motion, AR, or computer vision products.
• Experience testing multiplayer/local co-op or party games.
• Familiarity with Unity, Android-based hardware, or mobile gaming.
• Experience setting up consumer electronics (TVs, consoles, streaming devices).
• Experience with test automation or scripting (even small personal projects).
