• Create and maintain device drivers, hardware abstraction layers (HAL), bootloaders, diagnostics, and production test software
• Support board bring-up, hardware/software integration, debugging, and troubleshooting
• Work with RTOS and/or bare-metal embedded systems
• Develop communication interfaces using protocols such as UART, SPI, I2C, CAN, BLE, Wi-Fi, MQTT, or similar
• Participate in software architecture, requirements development, verification, risk controls, and traceability
• Execute unit, integration, regression, and system testing
• Support manufacturing, design transfer, production ramp-up, and post-market product maintenance
• Ensure compliance with quality and regulatory requirements throughout the software development lifecycle

Required Qualifications

To be considered, candidates should have:

• Bachelor's degree in Electrical Engineering, Computer Engineering, Computer Science, Embedded Systems Engineering, or a related technical discipline
• 3+ years of embedded firmware development experience
• Strong programming experience in Embedded C/C++
• Experience developing firmware for embedded microcontrollers
• Experience using embedded development tools, debuggers, and version control systems (Git, Azure DevOps, Jira, etc.)
• Experience with communication protocols such as UART, SPI, I2C, CAN, BLE, Wi-Fi, or MQTT
• Experience debugging embedded systems using JTAG/SWD debuggers, oscilloscopes, logic analyzers, or similar lab equipment
• Experience working with RTOS or bare-metal embedded systems
• Strong understanding of software lifecycle processes, testing, verification, and documentation

Important Candidate Requirements

Please apply only if you have experience with ALL of the following:

• Embedded firmware development (not application or web software)
• Embedded C/C++
• Microcontroller-based products
• Hardware/software integration and debugging
• 3+ years of embedded software engineering experience

What Makes Someone Successful

You are:

• A hands-on embedded engineer who enjoys working close to the hardware
• Comfortable collaborating with electrical, systems, manufacturing, quality, and regulatory engineers
• Detail-oriented with strong documentation skills
• Passionate about building reliable, safety-focused products
• Able to balance innovation with quality and regulatory compliance

Strongly Preferred

Medical device experience OR experience developing products in another regulated industry (aerospace, industrial controls, automotive safety systems, etc.)

Preferred Qualifications

We're especially interested in candidates who have experience with:

• Medical device software development
• Other highly regulated industries such as aerospace, automotive safety systems, industrial controls, or life sciences
• IEC 62304 , ISO 13485, ISO 14971
• Software traceability and Design History Files (DHF)
• Secure firmware development and cybersecurity for connected devices

You'll work on products that directly improve patient care while collaborating with a multidisciplinary engineering team dedicated to innovation, quality, and regulatory excellence. This is an opportunity to develop technology that makes a meaningful difference in the lives of families around the world.
