Firmware Engineer, Wearable Medical Devices

Firmware Engineer – Embedded Systems (Wearable Medical Devices)

Full-time | On-site

This role is for a stealth medical device company incubated by Pareto Holdings.

We are building a next-generation wearable biosensor platform that measures biomarkers critical to managing clinical conditions. The company is venture-backed and operating in stealth while developing novel sensing technology at the intersection of biology, hardware, and software.

This is a hands-on engineering role at an early-stage operating company — not a venture capital or finance position.

We are seeking a Firmware Engineer to help design, implement, and validate embedded firmware for a wearable medical device platform. You will work closely with electrical engineers, mechanical engineers, and electrochemists to develop reliable, production-grade firmware that interfaces with novel biosensors and low-power hardware systems.

This role is ideal for an engineer who enjoys working close to hardware, writing performance-critical embedded code, and taking ownership of firmware from early prototypes through regulated production environments.

• Design, develop, and maintain embedded firmware for wearable medical devices
• Implement low-level drivers for sensors, peripherals, and communication interfaces
• Collaborate closely with electrical engineering on board bring-up, debugging, and system integration
• Develop firmware for data acquisition, signal processing, power management, and wireless communication
• Support integration of firmware with higher-level software and mobile applications
• Write clean, testable, and well-documented embedded code
• Participate in firmware validation, verification, and testing activities
• Support regulatory and quality requirements for medical device development (IEC 62304, ISO 13485)
• Assist with transitioning firmware from R&D prototypes to pilot-scale and production systems
• Troubleshoot firmware issues in development and released products as part of sustaining engineering

• Bachelor’s degree in Computer Engineering, Electrical Engineering, Computer Science, or a related field
• 3+ years of experience developing embedded firmware for hardware products
• Medical devices or wearables strongly preferred
• Strong proficiency in C/C++ for embedded systems
• Experience with microcontrollers and embedded platforms (ARM Cortex-M or similar)
• Familiarity with real-time operating systems (RTOS) and bare-metal development
• Experience interfacing with sensors, ADCs, and low-power peripherals
• Hands-on experience with wireless communication protocols (BLE required; Wi-Fi, NFC, or RF a plus)
• Comfort debugging firmware using JTAG/SWD, logic analyzers, and oscilloscopes
• Familiarity with hardware–software co-design and board bring-up
• Exposure to regulated product development (IEC 62304, ISO 13485, FDA design controls) is a strong plus
• Strong problem-solving skills and ability to work in a fast-paced, multidisciplinary environment
• Clear written and verbal communication skills
• Nice to have: experience with low-power firmware optimization or wearable form factors

This role includes a combination of office work, laboratory testing, and hands-on prototype development.

• Medical, dental, and vision insurance
• Health savings and flexible spending accounts
