Description
We are seeking an experienced Principal Software Engineer to lead the firmware development and cybersecurity engineering efforts for a Class III medical device. In this role, you will oversee embedded firmware architecture, direct security strategy (in partnership with third-party consultants), and drive excellence in software development planning and process.
 
You will collaborate closely with systems engineering, hardware, software, quality, regulatory, and clinical teams to deliver high-integrity, compliant, and secure solutions that meet both regulatory requirements and clinical needs. This is a full time on-site position and will require reporting to our offices located in Los Gatos, CA. 
 
Responsibilities, Skills & Hands-On Experience
Serve as the internal technical lead for cybersecurity. Review and evaluate third-party deliverables, including architecture reviews, threat models, penetration testing, and security summary reports.
Integrate safety and security considerations into design decisions, balancing clinical requirements with robust threat mitigation strategies.
Work closely with quality and engineering to drive adherence to software development processes compliant with IEC 62304, ISO 14971, FDA 21 CFR Part 820, and recognized cybersecurity standards. Recommend and implement SOP updates to advance best practices within the software organization.
Lead the embedded firmware development lifecycle — from architecture and design through implementation, verification, and release — ensuring alignment with system and product-level requirements.
Establish and maintain development plans.
Support regulatory submissions and responses, including cybersecurity documentation and technical justifications. 
Coordinate with the Clinical group to prepare and maintain customer-facing security documentation, including the Manufacturer Disclosure Statement for Medical Device Security (MDS2).
 
Education & Work Experience
Bachelor’s or Master’s degree in Computer Science, Computer Engineering, or related discipline.
Strong knowledge with IEC 62304, ISO 14971, FDA cybersecurity guidance, and SBOM/VEX practices.
10+ years of combined software and firmware development experience in the medical device industry.
Strong proficiency in C and C++, real-time embedded systems, bare-metal programming, and low-level driver development (I²C, SPI, UART, ADC/DAC).
Proven experience with formal software lifecycle processes, version control (e.g., Git), static analysis, and automated testing tools.
Skilled in using oscilloscopes, logic analyzers, DVMs, and hardware debuggers.
Demonstrated success in managing external cybersecurity vendors, including defining scopes of work and evaluating deliverables.
Strong understanding of microcontrollers, hardware interfaces, safety-critical systems, and secure design principles.
Excellent communicator and proven leader who can mentor engineers and improve processes.
Nice to Have: Motor control, cardiac device experience, STM32/TI-C2000, and prior regulatory submission exposure.
 
 Our salary ranges are calculated by role, level, and location. Please note that your position within that range will be determined by your job-related knowledge, location, skills, experience, relevant education, and training/certifications.
