Embedded & Hardware Product Engineer

We are looking for an experienced Embedded & Hardware Product Engineer to join us in developing a new AI-powered scientific calculator.

The product will combine a physical scientific calculator with a camera, AI-powered problem solving, connectivity, and a custom embedded system. We are currently at the research/prototyping stage and are looking for someone who can help us turn the concept into a reliable, production-ready hardware product.

We are looking for someone with strong hands-on experience in:

Embedded Systems

• C/C++
• ESP32 / STM32 or similar microcontrollers
• FreeRTOS or similar RTOS
• GPIO, I2C, SPI, UART, PWM
• Firmware architecture and development
• Device communication with REST APIs / cloud backends
• Wi-Fi / Bluetooth
• OTA firmware updates
• Device authentication and secure communication
• Low-power and battery-powered embedded systems

Hardware / Electronics

• Digital and analog electronics
• Schematic design
• PCB design and layout
• KiCad / Altium Designer or equivalent
• Power management and voltage regulation
• Li-ion/Li-Po battery systems
• USB-C charging and power management
• Display/LCD integration
• Keypad/matrix input systems
• Camera module integration
• Wi-Fi/Bluetooth module integration
• Component selection and BOM preparation
• Hardware debugging and testing

Product Development

• Rapid hardware prototyping
• PCB prototyping and revision
• Working with prototype manufacturers
• SMT/PCB assembly
• Hardware bring-up and validation
• Firmware + hardware integration
• Design for Manufacturing (DFM)
• Design for Assembly (DFA)
• Production testing / QA
• Troubleshooting hardware and firmware issues
• Experience taking a prototype toward a production-ready product

Experience with:

• Embedded Linux / Linux-based SoCs
• Camera + image processing
• OCR / computer vision devices
• 4G LTE modules
• BLE provisioning
• Cloud-connected IoT devices
• Secure device provisioning
• Hardware OTA systems
• 3D/CAD collaboration
• Injection-molded plastic product development
• CE / FCC / RED / EMC compliance
• RoHS / REACH / WEEE requirements
• Working with OEM/ODM manufacturers
• Consumer electronics manufacturing

You will be involved in designing and developing:

• Custom calculator hardware
• Main MCU/SoC architecture
• Scientific keypad system
• Display system
• Camera integration
• Wi-Fi/Bluetooth connectivity
• Optional cellular connectivity
• Battery and charging system
• Custom PCB
• Embedded firmware
• Device-to-cloud communication
• OTA update mechanism
• Hardware testing and validation
• Prototype development
• Manufacturing preparation

This is not a simple Arduino/ESP32 hobby project.

We are looking for someone who understands the full journey from:

Concept → Prototype → PCB → Embedded Firmware → Hardware Integration → Testing → Production Preparation

Experience with real-world consumer electronics or IoT products will be highly valued.

You do not necessarily need to have built a calculator before. However, you should have strong experience building and shipping embedded hardware products.

You will work closely with our Software/AI Engineer, who will handle:

• Backend
• AI integration
• APIs
• Database
• Cloud infrastructure
• Web/mobile software
• Overall software architecture

Your responsibility will primarily be the embedded, electronics, hardware integration, and physical product engineering side.

Please include:

1. Your CV / LinkedIn profile
2. GitHub or portfolio (if available)
3. Examples of embedded/hardware products you have worked on
4. Your specific role in those projects
5. PCB/firmware work you personally handled
6. Whether you have experience taking a prototype into production
7. Your expected rate/salary
8. Your availability

If you have experience with ESP32/STM32 + custom PCB + consumer electronics + production, please mention it clearly in your application.

• We are looking for someone who can take ownership of the hardware side and help us build a reliable, production-quality product, not just a proof of concept.
