Job Title : Senior Embedded Hardware Engineer, IoT & Wearable Devices

Company: NOOG Technologies

Location: Remote Employment Type: Full-time / Contract

About NOOG :NOOG is developing an intelligent wearable tracking device designed for camels and livestock. Our device combines motion tracking, health monitoring, GPS positioning, and wireless connectivity to provide real-time insights into animal movement, behaviour, and health. We have already developed and successfully tested a functional hardware prototype.

We are now entering the next phase of development, focused on hardware redesign, power optimization, cellular connectivity, sensor integration, and preparing the device for scalable production.

We are looking for an experienced Senior Embedded Hardware Engineer to lead the electronics engineering and hardware redesign of our next-generation device.

The Role

You will work closely with our software engineering team and industrial/product designers to redesign and enhance our existing IoT wearable device. This is a hands-on engineering role requiring practical experience in PCB design, embedded electronics, wireless communication, low-power hardware architecture, battery management, and sensor integration. You will be responsible for taking our existing hardware design and transforming it into a more reliable, power-efficient, compact, and production-ready product.

Key Responsibilities

1. PCB Design & Hardware Architecture

- Review and analyze our existing schematics, Gerber files, PCB layouts, and hardware architecture.
- Redesign and optimize the existing PCB to accommodate new hardware components.
- Select appropriate electronic components, sensors, communication modules, and power-management ICs.
- Develop and validate updated schematics, PCB layouts, and manufacturing files.
- Ensure hardware reliability, durability, and suitability for outdoor livestock applications.

2. GSM / 4G LTE Connectivity

- Research, evaluate, and integrate low-power 4G LTE cellular modules.
- Identify suitable modules supporting UAE telecom frequency bands and regional/global deployment.
- Evaluate LTE Cat-1 bis, LTE-M, NB-IoT, and other suitable cellular technologies based on coverage, power consumption, and data requirements.
- Design SIM-based connectivity, allowing each device to communicate directly with our cloud platform without requiring customers to install additional network infrastructure.




- Evaluate the technical and commercial feasibility of retaining LoRa alongside cellular connectivity.

3. Power Management & Solar Integration

- Redesign the power architecture to improve battery life and overall energy efficiency.
- Evaluate lithium-ion and alternative battery technologies for extended operating time.
- Research and integrate adaptable, laminated solar panels for supplementary charging.
- Design battery charging, protection, and power-management circuits.
- Optimize power consumption across GPS, GSM, sensors, and embedded electronics.
- Target extended autonomous operation with minimal manual charging requirements.

4. Sensor Integration & Wearable Technology

- Integrate temperature and heart-rate sensors directly into the bottom surface of the device for skin-contact measurements.
- Research suitable optical heart-rate sensing technologies and temperature sensors.
- Evaluate sensor placement, contact pressure, signal quality, and measurement accuracy.
- Work with the product designer to develop an ergonomic enclosure that maintains reliable sensor-to-skin contact.
- Integrate IMU, accelerometer, gyroscope, barometric, and other relevant sensors.

5. Embedded Firmware & Communication

- Develop and optimize embedded firmware for the redesigned hardware.
- Implement sensor data acquisition, processing, and communication protocols.
- Support offline data storage and synchronization when connectivity becomes available.
- Implement remote configuration and secure OTA firmware updates.
- Optimize GPS tracking, cellular communication, and power-saving modes.
- Work with the software team to ensure reliable hardware-to-cloud communication.

6. Prototyping, Testing & Production

- Build and validate functional hardware prototypes.
- Perform power-consumption, battery-life, connectivity, sensor-accuracy, and environmental testing.
- Debug hardware and firmware issues.
- Coordinate with PCB manufacturers and electronic component suppliers.
- Prepare technical documentation, BOMs, manufacturing files, and testing procedures.





Required Technical Skills

- 3–5+ years of hands-on experience in embedded hardware engineering, electronics design, or IoT product development.
- Strong experience with PCB design tools such as Altium Designer, KiCad, or equivalent.
- Proven experience designing and modifying multilayer PCBs.
- Experience with STM32, ESP32, or similar microcontroller platforms.
- Practical experience integrating 4G LTE/GSM modules and wireless communication technologies.
- Strong understanding of LTE modules, SIM interfaces, antennas, RF design, and cellular frequency bands.
- Experience with lithium-ion battery systems, charging circuits, solar charging, and low-power electronics.
- Experience with IMU, GPS, temperature, and biometric sensors.
- Proficiency in C/C++ and embedded firmware development.
- Experience with UART, SPI, I2C, USB, and other hardware communication interfaces.
- Strong troubleshooting, prototyping, and hardware validation skills.

Good to Have

- Experience developing wearable technology or health-monitoring devices.
- Experience with optical heart-rate sensors (PPG) and skin-contact temperature measurement.
- Experience with LoRa / LoRaWAN and mesh networking.
- Experience developing solar-powered IoT devices.
- Experience with GPS tracking and geofencing.
- Experience designing rugged, waterproof, and dust-resistant electronic devices.
- Experience taking hardware products from prototype to mass production.

What We Are Looking For We are looking for someone who is not just familiar with electronics but has actually designed, developed, tested, and delivered working hardware products.

You should be comfortable making technical recommendations, evaluating alternative components, identifying engineering limitations, and taking ownership of the complete hardware development lifecycle. Previous experience developing a complete IoT or wearable hardware product is highly preferred.
