• Develop low-level drivers and interfaces for embedded peripherals, including SPI, I2C, UART, GPIO, ADC, PWM, and timer modules.
• Apply electrical engineering principles to the development, testing, and implementation of electrical components, equipment, and systems.
• Participate in requirements analysis, system design, integration, verification, and validation activities.
• Profile and optimize embedded firmware for performance, power consumption, memory utilization, and system constraints.
• Collaborate with hardware engineers, systems architects, project leaders, program managers, and product teams to translate system requirements into firmware solutions.
• Support technical reviews, troubleshooting, and root cause analysis for electrical and embedded system issues.
• Execute engineering activities within established development processes while supporting program and customer requirements.

Qualifications:

• U.S. Citizenship is required by Federal Law
• Department of Defense Secret security clearance required at time of hire.
