Embedded Systems Engineer: Real-Time, High-Throughput & OTA

OriginFlow; Hong Kong; On-site; HKD 300,000 - 600,000; Full time

Job summary

OriginFlow seeks an experienced embedded firmware engineer to develop low-level drivers and firmware for multi-sensor systems. You will design interrupt- and DMA-based data acquisition with zero-copy data paths and implement bootloaders and OTA frameworks for reliable updates.

Join a team building time-synced hardware with microsecond accuracy and high-throughput pipelines, including USB 3.0/Type-C streaming. Priorities include power optimization and comprehensive diagnostics and documentation.

Qualifications

• Strong C/C++ skills with real-time embedded systems.
• Experience with low-power embedded platforms and sensor drivers.
• Hands-on development with I2C, SPI, MIPI and UART.
• Familiarity with RTOS such as FreeRTOS or Zephyr.
• Experience debugging high-speed data acquisition systems.

Responsibilities

• Develop low-level drivers and firmware for multi-sensor systems.
• Design interrupt- and DMA-based data acquisition with zero-copy data paths.
• Implement bootloaders, OTA update frameworks, and core system services.
• Build hardware-level time synchronization with microsecond accuracy.
• Design high-throughput data pipelines for 200MB/s+ streams.
• Implement USB 3.0 / Type-C data transfer for real-time streaming.
• Optimize system power consumption and develop diagnostics tools.
• Author API references, integration guides, and troubleshooting documentation.
