Location R&D Centre - Hyderabad
Internal Stakeholders Design Team

1. JOB PURPOSE

To work as an Embedded Software Engineer with strong expertise in navigation systems, including INS (Inertial
Navigation Systems), IMU (Inertial Measurement Units), and GNSS (Global Navigation Satellite Systems). The role
involves navigation algorithm design, embedded firmware development, and sensor integration, along with rigorous
testing and calibration of navigation sensors to ensure accuracy and reliability in real-world environments.

2. PRINCIPAL ACCOUNTABILITIES
Accountabilities Major Activities

Software Analysis

• Develop, test, and optimize embedded C firmware for STM32 (ARM Cortex-M)
microcontrollers.
• Work with RTOS (FreeRTOS or equivalent) for real-time task scheduling and
system performance.
• Optimize code for real-time execution, memory efficiency, and power
consumption.
• Design and develop navigation and sensor fusion algorithms for INS, IMU, and
GNSS systems.
• Implement attitude estimation techniques using quaternions and Euler angles.
• Work on coordinate transformations, motion tracking, and filtering
techniques (e.g., Kalman filters).

Designing & Developing
embedded S/W

• Planning & Designing the S/W for embedded products.
• Firmware Coding
• Working on various communication interfaces like UART, SPI, I2C, CAN,
RS422, RS485 etc.
