Qualifications

• Bachelor's degree in Computer Science, Computer Engineering, Electrical Engineering, or a related discipline with a focus on embedded systems.
• 5-8 years of professional experience in embedded software development.
• Strong proficiency in C/C++ for embedded systems.
• Experience with RTOS or bare-metal development, including interrupt handlers, timers, DMA, context switching, and memory management.
• Demonstrated experience developing low-level drivers and hardware interfaces (SPI, I²C, UART, GPIO, timers, DMA, display or sensor interfaces).
• Familiarity with image processing or digital signal processing concepts.
• Hands-on experience debugging embedded systems using oscilloscopes, logic analyzers, JTAG/SWD, and in-circuit debugging tools.
• Ability to contribute independently to embedded development while working within a cross-disciplinary engineering team.

Responsibilities

• Design, implement, and maintain firmware and low-level embedded software for portable and wearable devices.
• Develop device drivers, hardware abstraction layers, and board support package components for custom ARM- and MCU-based platforms.
• Optimize image-processing and digital signal-processing algorithms for real-time execution on resource-constrained embedded hardware.
• Implement and manage multithreading, interrupt handling, and task scheduling inside RTOS or bare-metal environments.
• Utilize co-processing units (DSP blocks, GPU pipelines, SIMD, or FPGA-accelerated paths) to increase computational throughput.
• Work closely with hardware engineers to define firmware-to-hardware interface requirements, timing expectations, and configuration sequences.
• Troubleshoot and debug system-level issues involving display timing, sensor data alignment, memory bandwidth, and peripheral communication.
• Apply knowledge of discrete filters, Fourier transforms, linear systems, and fixed-point arithmetic to practical signal-processing tasks.
• Participate in full software lifecycle activities including design documentation, code reviews, unit tests, regression tests, and integration testing.
• Contribute to imaging, display, or sensor-based demo applications used for internal evaluation and customer demonstrations.
• Collaborate with Systems Engineering to ensure embedded implementations satisfy system requirements, timing budgets, and performance margins.
• Maintain firmware architecture and ensure modularity, clarity, and long-term maintainability across code bases.
