Job summary

Essc India in Hyderabad is seeking an Embedded Software Engineer to join our embedded systems team to develop and test low-level firmware for custom electronics in real-time and RF-based applications.

The candidate should have strong C, Embedded C, and C++, hands-on bare-metal firmware experience, and be proficient with microcontrollers (PIC, STM32, Atmel) and interfaces like SPI, I2C, and UART.

Qualifications

• Strong programming skills in C, Embedded C, and C++.
• Proficiency in bare-metal embedded software development (without RTOS).
• Hands‑on experience with PIC, STM32, or Atmel (AVR/SAM) micro-controllers.
• Solid understanding of communication protocols: I2C, SPI, UART – design and debugging.
• Experience with memory‑mapped I/O, clock configuration, and bootloader/firmware updates.

Responsibilities

• Develop embedded firmware from scratch for micro-controllers (bare-metal) using C, Embedded C, and C++.
• Program and interface PLLs over SPI, I2C, and UART.
• Work on PIC, STM32, and Atmel micro-controllers for real-time and low-level system applications.
• Perform unit testing, integration testing, and hardware validation using oscilloscopes and debugging interfaces.
• Collaborate with hardware teams to Bring up and test new PCB designs and embedded platforms.
• Optimize firmware for performance, memory, and power in embedded environments.
• Write clear documentation and maintain version-controlled code repositories.
