About The Position

We are seeking a Senior Embedded Software Developer to design and develop production-grade software for automotive IoT telemetry, embedded gateway, and intelligent battery-sensing products. This role spans heterogeneous embedded platforms, including bare-metal and RTOS-based ARM Cortex-M microcontrollers, embedded Linux on ARM Cortex-A processors, and machine-learning workloads running on dedicated NPUs. The successful candidate will contribute across the complete embedded software lifecycle—from hardware bring-up and low-level drivers to custom Linux distributions, connected applications, real-time firmware, and edge-ML integration. Target platforms include modern multicore SoCs such as the NXP i.MX 9 family, combining Linux application processors, real-time microcontroller cores, and neural processing accelerators.

Requirements

• Bachelor’s degree in Computer Engineering, Electrical Engineering, Computer Science, or a related discipline.
• 5+ years of professional embedded software development experience.
• Expert-level proficiency in embedded C and C++.
• Strong experience developing bare-metal firmware for ARM Cortex-M microcontrollers.
• Production experience with at least one embedded RTOS, preferably Zephyr or FreeRTOS.
• Strong understanding of: Interrupts, exceptions, and boot sequences, Concurrency and synchronization, Real-time scheduling and timing analysis, Memory-mapped I/O and DMA, Cache coherency and memory barriers, Linker scripts, startup code, and memory layouts, Low-power and resource-constrained design.
• Embedded Linux development experience on ARM Cortex-A platforms.
• Practical experience creating and maintaining custom Linux images with the Yocto Project.
• Experience with Linux kernel configuration, device trees, bootloaders, system services, and userspace development.
• Experience developing or integrating Linux device drivers and low-level hardware interfaces.
• Experience with common embedded communication interfaces and protocols, including: CAN and CAN FD, UART, SPI, I²C, Ethernet, USB.
• Experience with embedded networking and connected-device protocols such as TCP/IP, TLS, MQTT, HTTPS, or similar technologies.
• Experience using Git, automated builds, static analysis, unit testing, and continuous integration.
• Strong troubleshooting skills across hardware, firmware, operating systems, networking, and applications.
• Ability to translate system requirements into maintainable software architectures and well-tested implementations.
• Strong written and verbal communication skills.
