Embedded Software Engineer

Embedded Software Engineer

Responsibilities
Design, develop, and maintain C/C++ software for RTOS, Real-Time Linux, and Linux-based embedded controllers for real-time sensing, communication, monitoring, and device control.
Develop multi-threaded and real-time applications, including task scheduling, interrupts, synchronization, IPC, timers, state machines, watchdogs, and fault handling.
Develop and integrate low-level hardware interfaces and communication protocols including GPIO, UART, SPI, I²C, CAN/CAN-FD, Ethernet, TCP/IP, and UDP.
Develop and debug device drivers, BSP/HAL components, and hardware/software interfaces.
Perform system-level debugging and performance analysis, including latency, jitter, CPU/memory utilization, and communication performance.
Support networking and application interfaces including REST, MQTT, gRPC/Protobuf, and related technologies.
Develop Python tools for test automation, diagnostics, data collection, and hardware validation.
Participate in architecture/design reviews, code reviews, testing, integration, and system validation.
Required Qualifications
BS/MS in Computer Engineering, Electrical Engineering, Computer Science, or related field, with 5+ years of embedded/real-time software development experience.
Strong proficiency in C/C++ and working proficiency in Python.
Strong foundation in computer organization and architecture, including Von Neumann/Harvard architectures, CPU operation, registers, instruction execution, buses, and memory-mapped I/O.
Strong understanding of memory architecture, including cache, SRAM/DRAM/Flash, stack/heap, virtual/physical memory, DMA, and memory management.
Strong knowledge of Real-Time Operating Systems, including tasks/threads, scheduling, priorities, context switching, mutexes/semaphores, queues, synchronization, priority inversion, latency, jitter, and deterministic execution.
Strong understanding of hardware/software interrupts, ISRs, interrupt priorities, exceptions, interrupt latency, and interrupt-to-task interaction.
Hands-on experience with embedded controllers/microprocessors/SoCs and hardware interfaces such as GPIO, UART, SPI, I²C, CAN/CAN-FD, ADC/DAC, and Ethernet.
Experience with Embedded/Real-Time Linux, multithreading, IPC, sockets, device interfaces, and user-space/kernel-space concepts.
Ability to read schematics, datasheets, register maps, memory maps, and timing diagrams and debug hardware/software interactions.
Preferred Qualifications
Experience with FreeRTOS, Zephyr, QNX, VxWorks, ThreadX, PREEMPT_RT, ARM-based controllers, device drivers, BSPs, Yocto/Buildroot, industrial communication protocols, and JTAG/GDB/oscilloscope/logic-analyzer debugging.
Experience with BESS/HESS, BMS, PCS, power electronics, industrial controls, automotive, robotics, or other real-time control systems is a plus.
UL 60730 experience is a plus
