What Employers Look For
The qualifications that appear most often in firmware jobs.
- Proficiency in C and C++ for bare-metal and RTOS-based embedded development
- Experience with common communication protocols including SPI, I2C, UART, CAN, and USB
- Familiarity with debugging tools such as JTAG, SWD, oscilloscopes, and logic analyzers
- Bachelor's degree in electrical engineering, computer engineering, or computer science
- Experience with at least one RTOS such as FreeRTOS, Zephyr, or VxWorks
- Understanding of hardware schematics and ability to collaborate directly with hardware engineers
Tips for Your Firmware Job Search
Tailor your resume for embedded depth
List the specific microcontrollers, RTOSes, and communication protocols you've worked with rather than generic terms like 'embedded systems.' Hiring managers scan for STM32, FreeRTOS, CAN bus, and SPI because those are the tools their team uses daily.
Show hardware bring-up experience clearly
Firmware roles often screen for candidates who've taken a board from bare silicon to running code. If you've done bring-up work, call it out by name in your resume and describe the toolchain, debugger, and any silicon errata you navigated.
Apply early to roles that fit
Migrate Mate lists firmware openings from across the United States in one place, so you can find roles that match and apply directly to each listing.
Target job postings by target architecture
Filter your search by the processor architecture you know best, such as ARM Cortex-M, RISC-V, or AVR. Roles built around a specific architecture move fast and rarely require the full ramp time that generalist postings do.
Prepare a code sample or project teardown
Many firmware interviews ask you to walk through real code before any technical screen. Have a short, well-commented driver or state machine ready to share, and be prepared to explain every design decision including interrupt handling and memory constraints.
Negotiate scope, not just compensation
After an offer, ask which hardware platform you'd own first and whether the role includes schematic review responsibilities. Clarifying ownership early prevents situations where firmware engineers spend months debugging undocumented hardware without the authority to flag design issues upstream.
Firmware Jobs: Frequently Asked Questions
Which companies are hiring the most firmware engineers?
The companies hiring the most firmware engineers right now include Apple, Tesla, and AMD, with the largest share of openings in California, Texas, and Massachusetts, based on current listings on Migrate Mate as of September 2026. Hiring is particularly active in automotive, medical device, and consumer electronics segments.
How many firmware jobs are remote?
About 39% of firmware openings are fully remote or hybrid as of September 2026, which is lower than most software disciplines because hardware access and lab time are often required. Roles focused on higher-level application firmware, protocol stacks, or firmware tooling tend to offer the most remote flexibility.
How do you become a firmware engineer?
Start by building a strong foundation in C programming and computer architecture, then work through hands-on projects using a development board such as an STM32 or Arduino to write drivers and interface with peripherals. Learn how an RTOS schedules tasks and handles interrupts, read datasheets and reference manuals regularly, and build a portfolio of small projects that demonstrate real hardware interaction before applying.
Can you get a firmware job with little experience?
You can get an entry-level firmware role with limited professional experience if you can demonstrate hands-on project work. Build two or three projects that show you can write peripheral drivers, handle interrupts, and read a datasheet independently. Roles at smaller companies and startups in consumer electronics or IoT often hire candidates who show strong fundamentals and a history of shipping working embedded code, even without prior employment in the field.
What does the firmware interview process look like?
Most firmware interviews begin with a recruiter call covering your background and the role, followed by a technical phone screen that tests C fundamentals, bitwise operations, and basic hardware concepts. A take-home coding exercise or live coding session involving a driver or state machine is common next. Final rounds typically include a system design discussion, a code walkthrough of your own past work, and conversations with hardware and software team members you'd collaborate with directly.
Where can I find and apply to firmware jobs?
You can find and apply to firmware jobs on Migrate Mate, which lists current openings from across the United States. Find roles that match your background and apply directly to each listing without leaving the platform.
