About the Role

As our Lead Firmware Engineer, you will own the "brain" of our next-generation breast pump technology. This is a high-impact role where you will bridge the gap between complex motor control and seamless wireless connectivity. You will work closely with a small team of engineers, contributing to technical direction while staying hands-on in the codebase.

You will ensure our products are not only innovative but meet the highest safety and regulatory standards for Class II medical devices.

Key Responsibilities

• Architecture & Development: Lead the design and implementation of firmware for our wearable breast pumps, focusing on motor control algorithms, power management, and sensor fusion.
• Connectivity: Architect and optimize BLE (Bluetooth Low Energy) communication protocols to ensure rock-solid pairing between the device and our mobile application.
• Regulatory Compliance: Ensure all firmware development follows IEC 62304 software lifecycle standards and supports ISO 13485 quality management systems.
• Hardware Abstraction: Work closely with the Electrical Engineering (EE) team on hardware bring-up, debugging, and component selection (MCUs, drivers, batteries).
• Testing & Validation: Develop automated test frameworks and unit tests to ensure 100% reliability in a mission-critical medical context.
• Prototyping & Cross-functional Collaboration: Work closely with mechanical and electrical engineers to bring new breast pump and maternal health prototypes to life, from early concept through functional validation.

Required Qualifications

• Education: BS/MS in Computer Science, Electrical Engineering, or a related field.
• Firmware Expertise: 7+ years of experience in embedded C/C++. Experience with RTOS (e.g., FreeRTOS, Zephyr) and/or bare-metal development.
• Connectivity: Experience with BLE stacks and mobile-to-device data synchronization. STM32WBxxx series experience a plus.
• Motor Control: Familiarity with PWM or PID loops for motor control.
• Regulated Industry Experience: Proven experience shipping products in a regulated environment — medical devices (FDA/CE), aerospace, automotive (ISO 26262), or similar. Direct IEC 62304 / ISO 13485 experience is a strong plus but not required.
• Leadership: Experience leading technical projects or mentoring engineers in a fast-paced environment.

Bonus Points If You Have...

• Experience implementing hardware-based security features (e.g., Secure Boot, TrustZone, Cryptographic Co-processors).
• Experience with low-power optimization for battery-operated wearables.
• Familiarity with Over-the-Air (OTA) update implementation.
• Direct experience shipping Class II medical devices under FDA/CE pathways.
• A passion for women's health and FemTech innovation.

Location

This is a hybrid role based in Mountain View, CA. We expect 2–3 days per week on-site for hands-on hardware bring-up, lab debugging, and close collaboration with our engineering team. We aim for flexibility outside of those needs.
