Firmware Engineer

We're looking for a Firmware Engineer to build and maintain reliable embedded systems for sensor-driven hardware, working closely with the Lead Firmware Engineer across sensor integration, connectivity, and power management.

Responsibilities:

• Develop and maintain RTOS-based firmware for embedded devices, keeping real-time performance stable.
• Implement drivers and communication logic for sensors over I2C, SPI, or UART, and support arbitration across shared buses.
• Support BLE-based firmware development for reliable data transfer between devices and the cloud.
• Contribute to firmware-level battery charging safety, thermal cutoff logic, and clock stability under real-world conditions.
• Support OTA update mechanisms, including testing rollout and rollback behavior before release.
• Debug hardware-firmware interaction issues using tools such as oscilloscopes and logic analyzers.
• Write and maintain unit and hardware-in-the-loop tests to catch issues before they reach the field.

Requirements:

• You have a B. Tech in Electronics, Computer Science, or a related field from a Tier 1 institute (IIT, NIT, BITS Pilani, or equivalent) mandatory.
• You have 4+ years of embedded firmware experience.
• You have a solid understanding of RTOS concepts and at least one communication protocol used in sensor-based systems (I2C, SPI, UART, or BLE).
• You're proficient in C and C++ for embedded and microcontroller-based systems.
• You're comfortable reading datasheets and debugging at the hardware-firmware boundary.
• Bonus: experience with battery charging circuits or power-path management.
• Bonus: exposure to OTA update mechanisms for fleet-deployed embedded devices.
• Bonus: experience working with thermal sensors, IMUs, or camera modules.
