As a Firmware Engineer, you will design, develop, and test embedded firmware solutions for cutting‑edge IoT and consumer electronics devices, ensuring high reliability and performance in real‑world deployments. You will work closely with hardware teams to translate schematics and specifications into efficient, maintainable C code, while also collaborating with software and quality assurance teams to deliver end‑to‑end product excellence. Your role will involve troubleshooting complex firmware bugs, optimizing power consumption, and adopting industry‑standard version control and CI/CD pipelines to accelerate product releases. You will also contribute to the continuous improvement of our iterative development processes, mentor junior team members, and stay abreast of emerging microcontroller architectures and secure coding practices.
**Requirements**
𝗞𝗲𝘆 𝗥𝗲𝘀𝗽𝗼𝗻𝘀𝗶𝗯𝗶𝗹𝗶𝘁𝗶𝗲𝘀
Develop and maintain firmware in C for microcontroller and SoC platforms.
Design low‑level drivers and interface modules for peripherals (UART, SPI, I2C, GPIO, ADC, etc.).
Perform code reviews, static analysis, and unit testing to ensure firmware quality.
Work with hardware engineers to debug timing, signal integrity, and power‑management issues.
Create and maintain documentation, including design specifications, application notes, and release notes.
Collaborate with SW teams to implement RTOS‑based tasks and real‑time communication protocols.
Optimize code for memory footprint, execution speed, and power consumption.
Participate in hardware‑software integration testing and field validation.
Research and evaluate new tools, IDEs, and MCU families to enhance development workflows.
Contribute to the development and maintenance of CI/CD pipelines for firmware builds and deployments.

3+ years of professional experience writing firmware in C for embedded systems.
Strong understanding of microcontroller architectures, interrupt handling, and peripheral interfacing.
Experience with RTOS fundamentals, task scheduling, and inter‑task communication mechanisms.
Proficiency in debugging tools such as JTAG, SWD, and logic analyzers.
Familiarity with version control systems (Git) and CI/CD pipelines for embedded firmware.
Ability to write clear, concise technical documentation and release notes.
Excellent problem‑solving skills and a methodical approach to diagnosing hardware‑software interaction issues.
Comfortable working in a cross‑functional team environment with Agile/Scrum workflows.
Passion for staying up‑to‑date with industry trends, new MCUs, and secure firmware practices.
This guide is for freshers and working developers in India who use Git every day and now have to explain it in an interview: campus hires, engineers at service companies moving to product teams, and leads who review pull requests. It has 60 questions in three levels. Easy covers the staging area, commits, branches, merges and remotes. Medium covers what goes wrong at work: rebasing, conflicts, reset versus revert, lost commits, rejected and forced pushes. Hard covers Git internals, branching strategies, protected branches, merge queues, large repositories and GitHub Actions security. Every command output shown comes from running Git 2.43 on small practice repositories. Run the commands in a scratch repository of your own, then take the mock test.
