** 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:  + Bit Bake recipes and layers  + Machine and distribution configurations  + Kernel, boot loader, 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.  
** What we look for
**** Required
* ** Bachelor’s degree in Computer Engineering, Electrical Engineering, Computer Science, or a related discipline.
* ** 5+ years of professional embedded software development experience**.
