Freelance Embedded Firmware Engineer information

What does a freelance embedded firmware engineer do?

A Freelance Embedded Firmware Engineer designs, develops, and tests low-level software (firmware) that controls hardware devices. They often work on projects such as microcontroller programming, developing drivers, or integrating sensors and peripherals in embedded systems. As freelancers, they typically work with multiple clients, providing expertise in areas like C/C++ programming, hardware interfacing, and debugging. Their role is crucial in making electronic devices function efficiently and reliably.

What are the key skills and qualifications needed to thrive as a freelance embedded firmware engineer?

To thrive as a Freelance Embedded Firmware Engineer, you need strong expertise in C/C++ programming, microcontroller architectures, and embedded systems design, usually supported by a degree in electrical engineering, computer engineering, or a related field. Familiarity with debugging tools, version control systems (like Git), real-time operating systems (RTOS), and relevant industry certifications such as ARM or IoT certifications is often required. Excellent problem-solving, self-management, and client communication skills are crucial for coordinating projects and delivering solutions independently. These abilities are essential to meet client expectations, deliver robust firmware solutions, and succeed in a highly technical and autonomous work environment.

What are some common challenges faced by freelance embedded firmware engineers when working with remote clients?

Freelance embedded firmware engineers often encounter challenges such as aligning on hardware specifications without physical access, navigating diverse toolchains or development environments, and ensuring clear communication across time zones. Managing expectations and maintaining thorough documentation is key, especially when troubleshooting or delivering updates remotely. Building trust with clients requires proactive status reporting, flexibility in accommodating client workflows, and strong problem-solving skills to address unforeseen hardware or integration issues.

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

Job description

This position has the option to be located in either our Cincinnati, OH or Mooresville, NC office.
Corvid Technologies is seeking a talented and motivated Firmware Engineer to join our Electrical Engineering team. In this role, you will be responsible for designing, developing, and debugging low-level software that brings our next-generation hardware products to life.
This position will work closely with cross-functional teams consisting of hardware engineers, systems engineers and key stakeholders to deliver embedded solutions from concept to production. Success in this role requires active, hands-on lab work utilizing oscilloscopes, logic analyzers, and similar tools to bring up and validate hardware prototypes.
Key Responsibilities:
  • Architecture & Development: Lead the design and implementation of modular, maintainable, and robust firmware utilizing Embedded C and C++ in both bare-metal and Real-Time Operating System (RTOS) configurations. Extensive knowledge of state machines and similar designs patterns
  • Hardware Integration & Bring-Up: Work closely with Electrical Engineering (EE) teams during schematic design, layout reviews, and initial board bring-up. Evaluate and troubleshoot sub-circuits within the custom PCB and validate sensor functionality to resolve complex hardware/software interaction issues
  • Peripheral & Protocol Development: Architect and optimize hardware abstraction layers (HAL) and low-level communication protocols including SPI, I2C, UART, CAN bus and USB
  • Testing & CI/CD: Develop test suites for hardware-in-the-loop (HIL) testing and unit testing. Implement code-review standards and drive automated firmware compilation through CI/CD pipelines
  • Communication & Customer Interface: Capability to define and adapt requirements and break down problems to achieve defined development schedules. Exhibits strong problem-solving skills and knowledge to assist both internal and external customers through the project life cycle and design reviews

Requirements:
  • Ability to obtain/maintain a DoD Secret Clearance is required.
  • Bachelor's degree in Electrical Engineering, Computer Engineering, Computer Science, or a closely related technical field
  • 3+ years of professional engineering experience delivering production-ready firmware for commercial or industrial embedded systems
  • Mastery of Embedded C and C++. Experience with Python or Bash for scripting and testing is a strong asset as well as the ability to adapt new languages and software frameworks to various projects
  • Hands-on experience developing for microcontrollers and microprocessors leveraging ARM Cortex and RISC-V architectures. Knowledge of Field-Programmable Gate Arrays (FPGA), System on Modules (SoM) and single board computers (SBC).
  • Experience using physical hardware debugging infrastructure via JTAG / SWD and standard electronic lab bench equipment.
  • Proficiency with modern version control systems (Git) and Agile project management lifecycles
