Staff / Principal Embedded Firmware Engineer
About SleepRes
SleepRes is developing next-generation sleep apnea therapy technologies that improve patient outcomes. We are a small, fast-moving R&D team focused on building high-quality medical devices that make a real-world impact.
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
