  • Experienced in code development in C/C++ and assembly language for embedded targets using ARM Cortex-M processors. 
  • Understanding of SoC (System on Chip) architecture, bus systems, and memory hierarchy. Experience with general-purpose data movement engines, memory management units, memory protection, L1/L2 caches, inter-processor communications, shared memories, and dual-port memories. 
  • Experience in power optimization for embedded systems. Expertise in voltage and frequency scaling, clock gating, and sleep/wake cycles. Familiarity with low-power modes of processors and peripherals. 
  • Experience with profiling and analyzing power consumption at software and hardware interaction layers. 
  • Hands-on experience with tools like oscilloscopes, power analyzers, and logic analyzers. 
  • Familiarity with software power modeling tools and simulators. 
  • Experience in writing functional allocation and software requirements specifications with an eye towards customer use cases and testability. 
  • Knowledge of the power requirements of wireless protocols (BLE, WiFi, 802.15.4) is a plus. 
  • Familiarity with at least one MCU IDE on Windows from ARM/Keil, IAR, Eclipse, or others. 
  • The candidate must be able to independently manage assigned tasks, prioritize workload, and meet deadlines with minimal supervision. Proactive problem-solving skills and the ability to seek clarification when needed are essential.

Why are you being asked to complete this form?

We are a federal contractor or subcontractor. The law requires us to provide equal employment opportunity to qualified people with disabilities. We have a goal of having at least 7% of our workers as people with disabilities. The law says we must measure our progress towards this goal. To do this, we must ask applicants and employees if they have a disability or have ever had one. People can become disabled, so we need to ask this question at least every five years.

Completing this form is voluntary, and we hope that you will choose to do so. Your answer is confidential. No one who makes hiring decisions will see it. Your decision to complete the form and your answer will not harm you in any way. If you want to learn more about the law or this form, visit the U.S. Department of Labor’s Office of Federal Contract Compliance Programs (OFCCP) website at www.dol.gov/ofccp.
