Senior Engineer, Embedded Software

What we look for 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. How you will do it Architect, design, implement, test, and maintain embedded software for automotive telemetry gateways and intelligent battery sensors. Develop bare-metal C/C++ firmware for ARM Cortex-M microcontrollers. Develop real-time applications using Zephyr RTOS and FreeRTOS , including tasks, synchronization, interrupt handling, timing, and resource management. Develop Board Support Packages, boot code, peripheral drivers, and hardware abstraction layers. Build and maintain custom embedded Linux distributions using the Yocto Project , including: BitBake recipes and layers Machine and distribution configurations Kernel, bootloader, device-tree, and driver integration Package selection, image generation, and update strategies Reproducible build and release processes Develop Linux userspace services and applications for LTE-connected automotive gateways. Develop software for heterogeneous SoCs containing ARM Cortex-A, ARM Cortex-M, and NPU cores. Design communication and coordination between Linux, RTOS, and accelerator domains using mechanisms such as RPMsg, OpenAMP, shared memory, IPC, and vendor-provided frameworks. Integrate and optimize machine-learning inference workloads for NPUs and other edge accelerators. Develop telemetry data acquisition, processing, storage, and secure cloud-communication pipelines. Develop firmware for intelligent battery sensors and analog front ends that measure battery voltage, current, and temperature. Implement or integrate algorithms supporting battery State of Charge (SOC) and State of Health (SOH) estimation. Integrate LTE modems, GNSS receivers, sensors, vehicle networks, and other gateway peripherals. Implement robust fault detection, diagnostics, logging, watchdog, recovery, and over-the-air update capabilities. Analyze system performance, memory utilization, timing, power consumption, and communication reliability. Debug complex hardware/software and multicore issues using oscilloscopes, logic analyzers, JTAG/SWD debuggers, trace tools, and protocol analyzers. Produce software requirements, architecture documents, interface specifications, design documentation, and verification evidence. Conduct code and design reviews and mentor other embedded software developers. Collaborate with systems, hardware, cloud, data science, cybersecurity, validation, manufacturing, and product teams. Support prototype development, system integration, vehicle testing, production launch, and field-issue resolution.
