Freelance Embedded System Software Engineer information

What does a freelance embedded system software engineer do?

A Freelance Embedded System Software Engineer designs, develops, and tests software that runs on embedded systems, which are specialized computing systems within larger devices like cars, appliances, or industrial machines. They typically work independently or on a contract basis, collaborating with clients to understand requirements and deliver customized software solutions. Their responsibilities often include writing low-level code, optimizing for performance and memory usage, and troubleshooting hardware-software integration issues.

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

AspectFreelance Embedded System Software EngineerEmbedded Firmware Developer
CredentialsTypically requires a degree in electrical engineering, computer science, or related fields; certifications are optionalSimilar educational background; certifications like Certified Embedded Systems Engineer can be advantageous
Work EnvironmentIndependent, project-based work often remote; collaborates with multiple clientsUsually employed by a company or works on in-house projects; may work on-site or remotely
Industry UsageUsed across various industries including IoT, automotive, consumer electronicsPrimarily in product development, consumer electronics, automotive, and industrial systems

Both roles require embedded programming skills and knowledge of hardware. The main difference lies in the work setting: Freelance Embedded System Software Engineers work independently on diverse projects, while Embedded Firmware Developers are often employed by companies focusing on firmware development for specific products.

How do freelance embedded system software engineers typically manage project scope and communication with clients?

Freelance embedded system software engineers often work independently or as part of small remote teams, making clear communication and project scope management essential. They regularly use project management tools and set milestones to clarify deliverables and timelines with clients. Addressing technical constraints and hardware integration challenges early in the process helps avoid misunderstandings. Frequent status updates and transparent discussions about changes or obstacles ensure projects stay on track and meet client expectations.

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

To thrive as a Freelance Embedded System Software Engineer, you need a solid background in embedded C/C++ programming, microcontroller architecture, and real-time operating systems, often supported by a degree in electrical engineering or computer science. Familiarity with hardware debugging tools, version control systems (like Git), and development platforms such as ARM, AVR, or PIC is typically required. Strong problem-solving skills, self-motivation, and clear client communication help freelancers stand out in this role. These competencies ensure reliable, efficient solutions and successful project delivery in dynamic and client-driven environments.

Job description

Qrypt's mission is to protect the world's data and restore privacy. Qrypt hardens cybersecurity and future-proofs encryption against quantum attacks by eliminating key transmission. Qrypt's unique technology independently generates symmetric keys at multiple endpoints for critical workflows today. We are a passionate team of engineers, physicists, and cryptographers committed to transforming the way the world safeguards data and communications!

Qrypt is looking for an Embedded Software Engineer to join our team. The Embedded Software Engineer will own the design, development, and test of digital logic and embedded software.

This position is in Germantown, MD (hybrid — 4 days in office per week)

What you'll do
  • Lead the design, development, and test of systems composing of hardware, digital logic, embedded software, Linux kernel modules, and user-space Linux software
  • Assist in the design, review, and debug of analog/mixed signal circuit boards
  • Develop a deep understanding of the domain (quantum random number generators, network security systems) to architect future products and systems and validate existing products and systems
  • Lead hardware/FPGA/software integration efforts
  • Develop manufacturing and test tools and procedures, and supervise their execution
  • Use AI-assisted and agentic development tooling to accelerate your work while owning the correctness and quality of everything you ship
  • Help shape how the team adopts AI-assisted development (instruction conventions, review standards) as tooling matures
  • Assist in project planning and management
What you'll need
  • Bachelor's degree in Electrical or Computer Engineering, or a similar technical field, (Math, Physics, Engineering) and/or relevant work experience
  • 4+ years of experience developing software for embedded platforms or the Linux kernel
  • Expertise in the design and development of embedded systems
  • Proficiency with C, C++, bash and/or Python
  • Experience in the installation, upgrade, configuration, and performance tuning of Linux-based servers
  • Experience with bringing up hardware

  • Familiarity with RF and low-noise analog circuit and board design
  • Familiarity with electronics lab/test equipment (oscilloscope, logic analyzer, etc.)
  • Familiarity with implementing signal processing and/or control system algorithms
  • Fluency with AI-assisted development and the judgment to apply it where it adds real leverage — reviewing, correcting, and taking full ownership of AI-generated work
  • Strong written and verbal communication skills
Benefits & Perks
  • Competitive Pay & Equity participation
  • Comprehensive health, dental and vision coverage
  • Strong 401(k) match
  • In-office lunch and snacks
  • The opportunity to be part of a company solving one of the most critical technology challenges of our time!
