R/D Software Engineer

You will architect and implement embedded‑to‑cloud solutions and Android interfaces for our next‑generation hardware. You’ll collaborate with mechanical and electronics teams to turn concepts into reliable, user‑friendly products.

Key Responsibilities:

Embedded Systems & Firmware Development

Design, develop, and test firmware for ARM Cortex (STM32), AVR (ATmega), ESP32, and Arduino microcontrollers.
Write efficient, real-time embedded C/C++ code for motor controllers, solar charge controllers, and sensor-based systems.
Develop and optimize PID control loops for precision tasks (e.g., leveling in laser land levelers).
Interface microcontrollers with various peripherals (PWM drivers, ADCs, encoders, relays, MOSFET drivers, etc.).

Implement and troubleshoot communication protocols:

UART, SPI, I2C
Modbus (RS-485), CAN Bus, LIN
Wireless: BLE, Wi-Fi, LoRa

GNSS System Integration

Integrate GNSS modules such as:

u-blox NEO-M8N, u-blox NEO-M9N
ZED-F9P (RTK-capable for high precision)
Ublox F9H / RTK dual-band modules
Parse and use NMEA, UBX, and RTCM protocols for position and correction data.

Develop algorithms for:

Real-time geolocation tracking
Heading and orientation determination
Precision land leveling, path-following, and area mapping
Implement support for RTK (Real-Time Kinematic) positioning using base-rover architecture.

Hardware-Software Interfacing

Work closely with the hardware team to design PCBs optimized for firmware functionality.
Assist in component selection, schematic validation, and PCB troubleshooting.

Use tools like:

Altium Designer
Eagle / KiCad
Logic Analyzers & Oscilloscopes
ST-Link, JTAG, AVR ISP programmers

Testing, QA & Deployment

Build test benches for lab simulations and functional testing.
Conduct field testing in agricultural and industrial environments to ensure performance in harsh conditions.
Perform debugging and root-cause analysis for failed modules or unexpected system behavior.
Maintain version control using Git and document all revisions and findings in project logs.

IoT & Data Integration (Bonus)

Design systems that can optionally upload field data to the cloud via MQTT or RESTful APIs.
Experience with platforms like ThingsBoard, Firebase, or AWS IoT Core is a plus.
Develop dashboards for field performance metrics, usage logs, and predictive maintenance.
