Key Responsibilities
As an Embedded Firmware Engineer, you will:
- Develop and maintain production-grade firmware for STM32 H & F Series MCUs.
- Utilise STM32CubeIDE, HAL, LL drivers, and CMSIS for efficient development.
- Design and implement robust, modular firmware architectures.
- Integrate multitasking functionalities using FreeRTOS.
- Implement and optimise industrial communication protocols.
- Develop secure bootloaders and Over-The-Air (OTA) update mechanisms.
- Optimise memory (Flash/RAM) and CPU utilisation to ensure high performance.
- Manage real-time constraints and develop solutions for interrupt-heavy systems.
- Conduct comprehensive debugging using JTAG/SWD, logic analysers, and oscilloscopes.
Required Qualifications & Skills
- Educational Background: Bachelor's degree in Electronics Engineering, Computer Science, or a related technical field.
- Experience: Minimum of 2 years of hands-on experience with STM32 microcontrollers.
- Programming Proficiency: Strong command of C programming for both bare-metal and RTOS environments.
- Debugging Expertise: Proven ability to debug effectively at both firmware and hardware levels.
- Embedded Systems Knowledge:
- Experience with STM32CubeIDE / HAL / LL drivers / CMSIS.
- Proficiency in FreeRTOS for multitasking implementations.
- Familiarity with DMA, Timers, ADC, PWM, and interrupt-driven architectures.
- Experience with communication protocols such as RS485 (Modbus RTU), UART, SPI, I2C, LoRaWAN (SX127x / SX126x), MQTT / MQTTS, and BLE provisioning.
Desired Attributes (Good to Have)
- Experience with high-performance MCUs (e.g., H7 dual-core).
- Knowledge of external memory interfaces (QSPI / SDRAM).
- Understanding of cryptography and secure firmware signing.
- Prior experience with field-deployed IoT devices.
- Exposure to agricultural or industrial automation systems.
- Ability to independently own firmware development for a device.
- Commitment to clean, scalable code architecture.
- Strong debugging mindset and problem-solving skills.
- Comfortable collaborating closely with hardware engineers.
- Adept at troubleshooting field issues and optimising power consumption.
- Experience with clock tree configuration and MPU/FPU usage (especially in H-series).
What We Offer
- A challenging and rewarding role in a rapidly growing Agri-tech sector.
- Opportunity to work on cutting-edge IoT solutions that make a real difference.
- A collaborative and innovative work environment.
- Competitive salary and benefits package (commensurate with industry standards and experience).
