What is a firmware engineer?

Firmware Engineers are professionals who design, develop, test, and maintain the low-level software (firmware) that allows hardware devices to function. This firmware acts as a bridge between the device's hardware and higher-level software, ensuring that hardware components operate correctly and efficiently. Firmware Engineers typically work with embedded systems, writing code in languages like C or C++ for microcontrollers, sensors, and other electronic devices. Their work is crucial in industries such as consumer electronics, automotive, medical devices, and telecommunications.

What are the key skills and qualifications needed to thrive as a firmware engineer, and why are they important?

To thrive as a Firmware Engineer, you need a solid background in embedded systems, C/C++ programming, and a relevant engineering degree such as Electrical or Computer Engineering. Familiarity with hardware debugging tools, version control systems like Git, and real-time operating systems (RTOS) is typically required. Strong problem-solving abilities, attention to detail, and effective communication skills help firmware engineers excel, especially when collaborating with hardware and software teams. These skills and qualities are crucial to ensure reliable, efficient firmware that seamlessly integrates with hardware products.

What are some common challenges firmware engineers face when working with cross-functional teams?

Firmware Engineers often collaborate closely with hardware designers, software developers, and QA teams. A common challenge is ensuring clear communication of technical requirements and constraints, as firmware must interface seamlessly with hardware and higher-level software. Misalignment or delays in one area can impact overall delivery, so Firmware Engineers need strong problem-solving and collaboration skills to address integration issues and keep projects on track. Regular cross-team meetings and thorough documentation help mitigate these challenges.

What is the difference between Firmware Engineer vs Embedded Software Engineer?

AspectFirmware EngineerEmbedded Software Engineer
CredentialsBachelor's in Electrical Engineering, Computer Engineering, or related fields; knowledge of hardware and low-level programmingBachelor's in Computer Engineering, Electrical Engineering, or related fields; strong programming skills in C/C++
Work EnvironmentDesigning and developing firmware for hardware devices, often working closely with hardware teamsDeveloping software for embedded systems, often in real-time environments
Industry UsageElectronics, consumer devices, IoT, automotiveConsumer electronics, medical devices, industrial automation

Firmware Engineers focus on creating low-level code that directly interacts with hardware components, while Embedded Software Engineers develop software that runs on embedded systems, often with a broader scope. Both roles require similar technical skills and often overlap in industries like consumer electronics and IoT.

How much money does a firmware engineer make?

A firmware engineer's salary varies by experience, location, and industry, but typically ranges from $80,000 to $130,000 annually in many regions. Entry-level positions may start lower, while experienced engineers with specialized skills in embedded systems and real-time operating systems can earn higher salaries. Certifications and proficiency with tools like C and assembly language can also influence compensation.

What does a firmware engineer do?

A firmware engineer designs, develops, and tests low-level software that controls hardware devices such as microcontrollers and embedded systems. They work with programming languages like C or C++, use tools like debuggers and oscilloscopes, and often collaborate with hardware engineers to ensure proper device functionality and performance.

Job description

About Us   

Fluxergy is a rapidly growing in vitro diagnostics company innovating on the cutting-edge of laboratory testing. We’re developing the first and only multi-modal point-of-care platform that enables molecular, clinical chemistry, immunoassay, and hematology testing on the same system.  

Our platform spans many markets including the clinical, veterinary, and food safety industries. We are seeking self-motivated problem solvers who are excited to help decentralize traditional laboratory infrastructure.  

At the core of our company’s identity is a strong foundation in engineering. We take great pride in our commitment to critical thinking and pragmatic problem-solving through a modular and systemic perspective. We hold the conviction that transparent communication, coupled with the flexibility to adjust to evolving scenarios and the willingness to venture beyond familiar territories, is crucial to both our success and yours.

About the Role

We’re looking for an engineer who’s ready to level up—not just in skill, but in impact. This role is built for someone who enjoys solving complex, not-fully-defined problems and wants to play an active part in shaping the product. You’ll be working on a system that’s evolving in real time, where your ideas and contributions directly influence what gets built and how it performs. 

You thrive in collaborative environments where ownership is shared, ideas are challenged, and progress happens as a team. You’re naturally curious, comfortable with ambiguity, and motivated by building something meaningful—not just maintaining it. If you enjoy turning complexity into clarity and want to grow alongside a team tackling hard problems together, you’ll feel right at home here. 

Team culture: 
- Positive 
- Proactive 
- Accountable  
- Team oriented 
- Continuous learner
- Great communicator  
- Build strong working relationships 
- Contribute to a productive team culture
 
What You Will Do
  • Develop, test, and release firmware for embedded and IoT-based systems
  • Ensure firmware reliability, performance, and quality across all stages of development
  • Bring up, verify, and debug new hardware systems, including the Fluxergy Analyzer
  • Collaborate with cross-functional teams to support system integration and troubleshoot issues
  • Identify, analyze, and resolve bugs or system-level challenges as they arise
  • Design and improve intra-device communication interfaces (UART, SPI, I2C)
  • Explore and implement new methodologies to enhance existing features, backed by data-driven analysis
  • Participate in code reviews across teams and contribute to engineering best practices
  • Create and maintain clear, thorough technical documentation
  • Build internal tools to support development, testing, and team efficiency
  • Be an awesome team member (see team culture bullets above).   
What You'll Need to Have
  • 5+ years developing and releasing firmware for embedded or IoT devices
  • Familiarity with embedded Linux, Yocto, and at least one RTOS
  • Proficiency in C (C98) and C++ (C++11)
  • Experience with bring-up, verification, and troubleshooting of embedded systems
  • Ability to design and improve communication protocols like UART, SPI, and I2C
  • Willingness to experiment, iterate, and apply quantitative analysis to improve systems
  • Ability to work effectively across teams and clearly document and share work
  • Comfort navigating ambiguity and tackling unforeseen challenges in a system built from the ground up
  • Background in medical devices or similar industries is highly valued 
Strong plus if you: 
  • Have worked on an FDA regulated project 
  • Are familiar with safety critical design processes and controls 
  • Ability to read schematics
