Description supplied by the original job listing.
KAEM is looking for an experienced Embedded Hardware & Firmware Engineer to support the development of a professional embedded communication system.
The role will involve both electronic hardware development and embedded firmware development, from schematic and PCB design through prototype bring-up, debugging, and system integration.
The ideal candidate should be comfortable working across both hardware and firmware and be able to take ownership of a product from engineering design through a working prototype.
Responsibilities
Review and refine system architecture and hardware requirements
Design complete electronic schematics
Develop multilayer PCB layouts using Altium Designer or equivalent tools
Design embedded systems using high-performance microcontrollers
Integrate external memory, digital audio, displays, wireless communication modules, sensors, and peripheral interfaces
Design power-supply, protection, filtering, reset, clock, and debug circuitry
Develop embedded firmware in C/C++
Develop firmware using an RTOS such as FreeRTOS
Implement low-level drivers for UART, SPI, I2C, I2S, PCM, TDM, GPIO, USB, Ethernet, and similar interfaces
Develop real-time audio communication and routing functions
Implement state machines, device control, watchdogs, fault recovery, and system diagnostics
Develop touchscreen/HMI applications using embedded GUI frameworks such as LVGL
Integrate wireless communication modules and external embedded devices
Perform prototype board bring-up and hardware debugging
Debug firmware and hardware using oscilloscopes, logic analyzers, JTAG/SWD debuggers, and other laboratory equipment
Optimize the system for reliability, low latency, EMI/EMC, thermal performance, and power integrity
Prepare designs for PCB fabrication and PCBA manufacturing
Support prototype testing, design revisions, and production release
Maintain clear technical documentation, source code, schematics, PCB files, and test procedures
Required Qualifications
Bachelor’s degree in Electrical Engineering, Electronics Engineering, Embedded Systems, Computer Engineering, or a related field
Minimum 5 years of professional embedded hardware and/or firmware development experience
Strong experience with schematic design and PCB layout
Strong proficiency with Altium Designer or similar professional PCB design tools
Strong embedded C/C++ programming skills
Experience with ARM Cortex-M based microcontrollers
Experience with FreeRTOS or another real-time operating system
Experience with high-performance MCU designs, external RAM/Flash, and multilayer PCBs
Experience with digital communication interfaces such as UART, SPI, I2C, USB, Ethernet, I2S, PCM, or TDM
Experience with mixed-signal electronics and audio circuitry
Experience with wireless or RF module integration
Good understanding of signal integrity, power integrity, grounding, EMI/EMC, ESD, and surge protection
Experience with board bring-up and hardware/firmware debugging
Experience taking electronic products from design through prototype and production
Preferred Experience
Real-time audio or communication systems
Intercom, conferencing, professional audio, or telecom products
NXP i.MX RT or similar high-performance microcontrollers
LVGL or embedded graphical interfaces
BGA PCB design and external memory routing
Industrial or automotive electronics
Wireless voice communication systems
Audio DSP, echo cancellation, or microphone processing
Embedded Linux integration
Product certification and EMC testing
What We Are Looking For
We are looking for an engineer who can work independently, make sound technical decisions, identify risks early, and collaborate with external manufacturers and technology vendors.
The ideal candidate should have practical experience taking a product through:
Architecture review → Schematic design → PCB layout → Firmware development → Prototype bring-up → Debugging → Design revision → Production readiness
Location: Saudi Arabia, Eastern Province / Al Khobar
Work Arrangement: On-site
Candidates should include examples of previous embedded hardware and firmware projects, particularly projects involving complex multilayer PCBs, real-time firmware, audio, wireless communication, or industrial electronics and share your resume to hr@kaemsolutions.com
