• Test Automation: Design, build, and maintain automated test scripts and hardware-in-the-loop (HIL) testing environments.
• Verification & Validation: Execute functional, regression, and stress testing against technical product specifications; document test protocols and bug tracking.
• Hardware Debugging: Utilize lab equipment such as oscilloscopes, logic analyzers, and digital multimeters to debug software-hardware integration issues.
• Code Review: Participate in peer code reviews and contribute to firmware architecture and safety-compliance standards.
• Collaborate with hardware and software teams to improve testability, traceability, and reliability across the product lifecycle.

Qualifications

• Eligible to obtain a U.S. Security Clearance – U.S. Citizenship required.
• Bachelor’s degree in Electrical Engineering, Computer Engineering, Computer Science, or a related field.
• Experience: 3 to 6 years of professional experience in embedded software development and software verification.
• Technical Skills: Strong proficiency in C/C++, real-time operating systems (RTOS), and bare-metal programming.
• Protocols: Direct experience with communication protocols such as I2C, SPI, UART, CAN, or USB.
• Testing Tools: Experience with automated testing frameworks (e.g., Python scripts, Unity, Ceedling, or similar) and standard lab hardware tools.

Working Conditions

Employees may be called upon to participate in in-person meetings, trainings, or company functions at Knowmadics offices or other designated locations. Travel in support of business operations may also be required, and employees are expected to comply with these obligations as part of their position.

Should be willing to work in a variety of settings as needed. Flexible to work long hours as required.

Physical Requirements

Prolonged periods working at a desk and computer, as well as in a laboratory or prototyping environment. Frequent use of hand tools, soldering equipment, and electronic test instruments. Must be able to lift and move equipment weighing up to 40 pounds.

All qualified applicants will receive consideration for employment without regard to race, color, religion, sex, sexual orientation, gender identity, national origin, disability, or protected veteran status.
