Job title: Embedded Software Engineer
Department: Information Technology
Reports to: Embedded Systems Lead
Location: [City], [office, branch or site]
About the role
An Embedded Software Engineer writes the software that runs inside devices and machines, from appliances and medical equipment to automotive and industrial controllers. At the entry level they write and test embedded C code, work with microcontrollers and sensors, and debug on real hardware under senior guidance. A good junior embedded engineer writes efficient code that fits tight memory and timing limits and tests carefully on the target board. The role sits in a product or R and D team and reports to an embedded lead or senior engineer.
Key responsibilities
- Write and test embedded C or C plus plus code for microcontrollers from clear specifications.
- Interface with sensors, actuators and peripherals over protocols such as I2C, SPI and UART.
- Debug code on real hardware using a debugger, logic analyser and oscilloscope with guidance.
- Write firmware routines that respect tight memory, power and timing constraints.
- Read datasheets and reference manuals to configure microcontroller peripherals correctly.
- Create unit and on target tests to confirm behaviour before integration.
- Fix defects found in testing and confirm the fix on the target board.
- Document code, pin configurations and test results for the team.
- Support hardware engineers during board bring up and integration.
- Learn the toolchain, real time concepts and debugging skills with support from seniors.
Requirements
- Graduate in electronics, electrical or computer engineering (B.E. or B.Tech)
- Working knowledge of embedded C and microcontrollers
- A hardware project or portfolio is an advantage
- Fresher or up to 2 years in embedded development

What does an embedded software engineer do?
An embedded software engineer writes the software that runs inside devices and machines, such as appliances, medical equipment and industrial controllers. They write embedded C code for microcontrollers, interface with sensors and peripherals, and debug on real hardware. Their code must fit tight memory, power and timing limits, so careful testing on the target board is essential.
What is the difference between embedded software and firmware?
The terms overlap. Firmware usually means the low level code stored in a device that controls the hardware directly. Embedded software is a broader term for any software running on an embedded device, which can include firmware plus higher level application logic. In practice many engineers use the words interchangeably.
Which degree is best for embedded engineering in India?
Electronics, electrical or computer engineering degrees suit embedded roles best, because the work sits between hardware and software. Employers look for embedded C skills, knowledge of microcontrollers and protocols, and hands on projects. A strong final year hardware project or internship often matters more than the exact branch of engineering.
