Firmware Development Engineer

Role Summary

You will develop embedded application firmware that runs on real‑time microcontrollers (ARM Cortex‑M, ESP32, RL78, etc.) within our product range. The firmware controls energy diversion, load management, CT clamp data reading, battery state, charging schedules based on tariffs, and delivers a reliable, safe, and responsive product experience.

Key Responsibilities

• Develop and maintain embedded C application firmware for real‑time microcontrollers (ARM Cortex‑M, RL78, ESP32).
• Implement and maintain low‑level peripheral drivers (SPI, I²C, UART, CAN, ADC, PWM, timers).
• Write clean, readable, well‑structured firmware code adhering to MISRA‑C guidelines.
• Implement and debug state machines and control logic for product features.
• Write unit tests and contribute to test frameworks; participate in hardware‑in‑the‑loop testing.
• Use Git for version control and Jira for task and sprint management.
