Embedded Systems Engineer for Advertising IoT: Embedded Linux, Rockchip, Hardware Integration

Mission

At OOHAi ( https://www.oohai.au/ ), we’re building edge AI systems that make the physical world measurable, interpretable, and responsive. You’ll play a key role in developing the embedded platform that powers our intelligent camera-based hardware — integrating custom electronics, AI acceleration, and real-time analytics into reliable, production-ready systems.

Core Responsibilities

• Design and optimize camera/vision pipelines (capture → preprocessing → inference → app I/O) to meet defined latency and FPS targets.

• Integrate and tune AI acceleration chips (e.g., Hailo) for real-time face detection and other inference workloads.

• Support transition from Raspberry Pi 5 to a fully custom hardware platform, collaborating remotely with our hardware manufacturer in China.

• Debug and integrate custom PCB boards, including power, communication buses, and peripheral bring-up.

• Harden embedded Linux systems — handle kernel modules, device trees, and low-level driver configuration.

• Ensure reproducible, maintainable deployments, including packaging, containerization, and CI integration.

• Maintain small device fleets with remote update capability, diagnostics, telemetry, and rollback safety.

• Document key procedures and produce clear reproducible examples (“golden path” builds, debug steps, and setup guides).

Must-Have Expertise

• Embedded Linux Development: Strong in both Python and C/C++ for low-level programming and service logic.

• Computer Vision Pipelines: Experience with camera capture APIs, multimedia frameworks, format negotiation, and latency/buffering optimization.

• Accelerator Integration: Model deployment and performance tuning on NPUs, DSPs, or GPUs (e.g., Hailo, Jetson).

• Linux Systems & Build Operations: systemd, udev, journald, Docker builds, cross-compilation, CI/CD with pinned toolchains.

• Electronics & Hardware Integration:

  • Read and interpret schematics and PCB documentation.

  • Bring-up via I²C, SPI, UART, GPIO, handle pull-ups, resets, and power sequencing.

  • Familiar with power integrity, thermal, and EMI/EMC considerations.

  • Comfortable with lab tools: oscilloscope, logic analyzer, multimeter.

• Kernel & Drivers: Device trees, driver configuration, and debugging using dmesg/logs.

• Networking & Remote Ops: Secure SSH access, port forwarding, and fleet management basics.

• Version Control: Clean Git hygiene, structured commits, bisecting, and reproducible build history.

Nice-to-Have Skills

• Understanding of camera sensor tuning, exposure/gain control, and MIPI CSI-2 fundamentals.

• Experience with ARM-based SBCs (Raspberry Pi, Rockchip, Jetson, etc.) and OS image customization.

• Familiarity with lightweight API layers for inference (e.g., FastAPI/gRPC).

• Practical experience with LTE/5G modems, watchdogs, and field device connectivity.

• Performance analysis tools: perf, flamegraphs, eBPF probes, and multimedia profiling utilities.

• Secure Boot and Device Security: Experience implementing trusted boot chains, encryption, and hardware-level security features.
