Embedded Software Engineer Job Description (2026): Duties, Skills and Salary

An embedded software engineer writes the software that runs directly on hardware: firmware for sensors, motor controllers, medical devices, automotive systems and consumer electronics. The work sits closer to the metal than most software jobs, with memory, timing and power constraints that general application code never has to think about.

Embedded engineers typically work in C or C++, read schematics and datasheets, and debug with oscilloscopes and logic analyzers as often as with a debugger. The role varies by industry: automotive and medical device work leans heavily on safety standards and testing rigor, while consumer electronics moves faster and iterates more loosely.

About [Company]

[Two or three sentences on what your company does, who it serves and why this team matters now.]

About the role

[Company] is hiring an embedded software engineer to develop firmware for [product, e.g. a sensor module, motor controller or IoT device]. You'll write and debug low-level code, work closely with hardware engineers, and help ship a product that has to work reliably in the field.

What you'll do

  • Design and write firmware in [C / C++] for [microcontroller/platform].
  • Debug issues using [oscilloscope, logic analyzer, JTAG debugger] alongside standard tools.
  • Work with hardware engineers to define interfaces and resolve hardware/software issues.
  • Write and maintain drivers for [sensors, communication protocols: I2C, SPI, UART, CAN].
  • Optimize code for memory, power and real-time performance constraints.
  • Write unit and integration tests, and support hardware-in-the-loop testing.
  • Document firmware architecture, interfaces and known limitations.
  • Support bring-up of new hardware revisions and field issue investigation.

What you'll bring

  • [X]+ years writing embedded software in C or C++.
  • Experience with microcontrollers and real-time operating systems (RTOS) or bare-metal programming.
  • Comfort reading schematics and datasheets, and debugging at the hardware/software boundary.
  • Experience with communication protocols such as I2C, SPI, UART or CAN.
  • Familiarity with version control and embedded build/toolchain workflows.
  • Strong debugging skills under real-time and resource constraints.

Nice to have

  • Experience with [specific RTOS: FreeRTOS, Zephyr, VxWorks].
  • Background in [automotive, medical device or industrial] safety standards.
  • Experience with wireless protocols (BLE, Wi-Fi, LoRa).
  • Python or scripting for test automation and tooling.

What we offer

  • [Pay range: e.g. $X–$Y base salary, plus bonus or equity if offered]
  • [Hardware lab access, conference budget, equipment stipend for home setup]
  • [Health cover, retirement or pension plan, paid time off, parental leave]
  • [Work authorization: whether you can sponsor a visa or hire through an employer of record]

[Our process: a recruiter call, a technical phone screen on C and embedded fundamentals, a take-home or live debugging exercise, and an on-site or virtual panel with the hardware and firmware teams.]

[Your equal opportunity statement, and how candidates can ask for adjustments during the process]

Put the pay range in the ad. Several US states, including California, Colorado, New York and Washington, require it in job postings, and the EU Pay Transparency Directive gives applicants the right to know the starting pay or its range before the interview.

Embedded Software Engineer duties by seniority

What the job usually looks like at each level. Pitch the ad at one level and say which in the title.

Junior

  • Implements well-scoped drivers and features under review.
  • Learns the hardware platform and debugging toolchain.
  • Fixes bugs identified by testing or senior engineers.

Mid-level

  • Owns firmware for a subsystem or product line.
  • Debugs complex hardware/software interaction issues independently.
  • Works directly with hardware engineers on new designs.

Senior

  • Architects firmware for new products and sets coding and review standards.
  • Leads bring-up and root-cause analysis on field failures.
  • Mentors engineers and represents firmware in cross-functional design reviews.

Embedded Software Engineer career path

  1. Embedded Software Engineer
  2. Senior Embedded Engineer
  3. Staff/Principal Embedded Engineer
  4. Embedded Systems Lead or Engineering Manager

Embedded engineers usually enter from an electrical engineering or computer engineering degree, or from a software background with a strong interest in hardware. The path deepens toward staff or principal roles focused on architecture, or moves into engineering management over a hardware/firmware team.

Embedded Software Engineer job description FAQ

What does an embedded software engineer do?

Writes firmware that runs directly on hardware: drivers, communication protocols and real-time logic for devices like sensors, controllers and IoT products. The work includes hardware-level debugging, not just writing code.

What languages and skills should an embedded engineer job description list?

C and C++ are the core languages, along with RTOS or bare-metal experience and familiarity with protocols like I2C, SPI or CAN. List the specific microcontroller platform and protocols the role actually uses.

Do embedded software engineers need an electrical engineering background?

Not always, but comfort reading schematics and datasheets and debugging at the hardware/software boundary is expected. Some embedded engineers come from EE degrees, others from CS with strong hardware interest.
