 Position Overview 

We are seeking a Staff / Principal Firmware Engineer to lead the design and development of embedded software for our medical devices. This is a high-impact technical leadership role where you will own firmware architecture and execution while contributing directly to product development from concept through commercialization. 

You will work closely with cross-functional teams (product, electrical, mechanical, and quality) to translate product requirements into robust, scalable embedded solutions. In addition to hands-on development, you will help define engineering standards, guide architectural decisions, and mentor other engineers. 

Our current stack is based on STM32 microcontroller devices, using Micrium C/OS III and SEGGER emWin. 

What You'll Do 

  • Lead firmware design, development, and verification for SleepRes products  
  • Architect scalable embedded systems and guide technical direction  
  • Translate user and system requirements into reliable firmware solutions  
  • Contribute to embedded GUI development and user experience implementation  
  • Participate in code reviews, design reviews, and risk management activities  
  • Support technical documentation (requirements, design, and test artifacts)  
  • Collaborate closely with cross-functional engineering teams  
  • Mentor engineers and help elevate team technical capability (Staff/Principal level)  

What We're Looking For 

  • BS in EE, CS, Biomedical Engineering, or related field (MS preferred)  
  • 7+ years (Staff) or 10+ years (Principal) of embedded firmware development experience  
  • Strong proficiency in C/C++ and ARM-based embedded systems  
  • Experience developing commercial firmware products  
  • Hands-on experience with embedded GUI development (e.g., emWin or similar)  
  • Experience with connected devices (cellular, Wi-Fi, BLE) 
  • Familiarity with embedded cybersecurity (secure boot, encryption, OTA updates)  
  • Strong systems thinking, debugging ability, and attention to detail  
  • Comfortable working in cross-functional, fast-paced environments  

Nice to Have 

  • Medical device experience (Class II)  
  • Experience with FDA submissions (e.g., 510(k)) and DHF documentation  
  • Signal processing or sensor-driven systems experience  
  • Exposure to manufacturing, test, and bring-up processes, including working with contract manufacturers  
  • Startup or early-stage product development experience

Compensation 

  • Staff: $170K – $200K 
  • Principal: $200K – $225K
