Job Summary

Mid-Level Embedded Systems Engineer . In this hands-on role, you will design and develop microcontroller-based electronic systems, from writing firmware to creating simple custom PCBs.

Responsibilities

Develop and debug firmware in C/Assembly for 8051, Arduino, and STM32 microcontrollers.

Design simple, reliable application PCBs for microcontroller-based systems.

Perform schematic entry, component selection, PCB layout, and basic design verification.

Test and validate hardware + firmware integration.

Support prototyping, troubleshooting, and minor design iterations.

Required competencies and certifications

Bachelor’s degree (B.E./B.Tech or equivalent) in Electronics Engineering, Electrical Engineering, Computer Engineering, or a related field.

3–5 years of hands-on experience in embedded systems development, specifically with microcontroller-based projects.

Strong proficiency in Embedded C (and basic Assembly where needed).

Proven experience programming the following microcontrollers:

8051 family (Keil μVision IDE preferred)

Arduino/AVR platform

STM32 (STM32CubeIDE, HAL/LL drivers, or STM32CubeMX)

Experience designing simple application PCBs using common 8051-type or similar microcontrollers:

Schematic capture and PCB layout

Familiarity with at least one PCB design tool (KiCad, Eagle, Altium Designer, or EasyEDA)

Basic understanding of component selection, power supply design, and signal integrity for low-to-medium complexity boards

Knowledge of common communication protocols (UART, I2C, SPI, etc.) and peripheral interfacing.

Hands-on debugging skills using tools such as oscilloscopes, logic analyzers, multimeters, and in-circuit debuggers (JTAG/SWD).

Ability to take a project from concept → schematic → PCB → firmware → testing/prototyping

Preferred competencies and qualifications

Experience with soldering, prototyping, and board bring-up.

Familiarity with version control (Git) and basic documentation practices.

Knowledge of real-time operating systems (RTOS) or bare-metal firmware design.

Any exposure to industrial, consumer electronics, or IoT projects.
