American IT Systems; Waukesha (WI); On-site; USD 120,000 - 160,000; Full time

Job summary

American IT Systems seeks a self-directed firmware engineer to contribute to embedded software for MR platforms. You will work across firmware, systems, hardware, and architecture teams to translate requirements into reliable software, leveraging strong C++ fundamentals and practical embedded development experience.

You will own firmware features, learn existing code and hardware interfaces, and help ensure high-quality software through unit tests, CI, and rigorous design reviews.

Qualifications

• Bachelor's degree or equivalent in Computer Engineering, Electrical Engineering, Computer Science, or related field.
• 5+ years of professional experience developing embedded or firmware software.
• Strong C++ programming skills, including OO design, memory management, concurrency, debugging, and maintainable production code.
• Hands-on experience with hardware interaction, real-time systems, device interfaces, or resource-constrained embedded platforms.
• Proven ability to learn unfamiliar technologies and codebases independently, break down ambiguous problems, and deliver results with minimal guidance.
• Experience with embedded development and diagnostic tools such as debuggers, emulators, protocol or logic analyzers, and system logs.
• Experience with Linux-based development environments, Git, and build/container workflows.
• Experience with CI, automated testing, and disciplined code reviews.
• Clear written and verbal communication, able to explain technical decisions and collaborate across functions.

Responsibilities

• Own firmware features from requirements through design, implementation, integration, verification, and defect resolution.
• Learn existing code, hardware interfaces, development tools, and system behavior independently.
• Develop maintainable embedded software in modern C++ with sound OO design and proper error handling.
• Collaborate with systems, hardware, FPGA, software, and architecture teams to clarify requirements and resolve cross-functional issues.
• Use debuggers, emulators, analyzers, and logs to isolate complex software/hardware interaction problems.
• Create unit and integration tests, contribute to automated testing, and support CI to improve quality and regression coverage.
• Participate in design and code reviews and provide constructive feedback.
• Estimate, plan, and track work through user stories and communicate risks and blockers.
• Follow quality processes and produce documentation for design traceability and maintenance.
• Work with globally distributed teams and contribute to consistent design and architectural improvements across MR platforms.
