• Lead embedded firmware development for Casana’s next-generation Smart Seat platform, from early board bring-up through production.
• Partner closely with hardware engineering to:
• Evaluate and select microcontrollers, wireless solutions, and supporting components based on system-level tradeoffs
• Rapidly develop prototype designs
• Identify and design field-replaceable units (FRUs) and configurable hardware options
• Develop an effective power management scheme
• Evolve Casana’s existing firmware platform to support the new hardware design while preserving higher-level application logic and system behavior.
• Architect and implement hardware abstraction layers that allow for:
• Multiple board variants
• Incremental hardware upgrades
• Long-term firmware reuse
• OTA updates
• Strong security
• Design and implement low-power firmware, including sleep/wake strategies, radio usage optimization, and battery-driven operation.
• Develop firmware for wireless charging-capable battery systems, including charge state management and fault handling.
• Build and maintain manufacturing and factory tooling, including:
• Board test and diagnostics firmware
• Programming and provisioning workflows
• Calibration and verification utilities
• Collaborate with cloud and algorithm teams to define firmware interfaces and data exchange formats.
• Provide technical leadership through code reviews, architectural guidance, and mentorship.
• Help define the technical roadmap for the Smart Seat platform as it evolves beyond a single hardware configuration.
• Contribute to the development of technical roadmaps and architecture for the firmware system.
• Stay up-to-date with the latest trends, technologies, and regulations in embedded software development, and proactively contribute ideas to enhance product capabilities and features.
• Perform other responsibilities as needed.

What You’ll Bring:

• Bachelor's degree in Computer Science, Software Engineering, computer engineering or a related engineering field. Master’s degree preferred.
• 7+ years’ experience in embedded software development within the medical device industry.
• Proficiency in C/C++ programming languages for embedded systems.
• Solid understanding of real-time operating systems (RTOS), device drivers, bootloaders, and low-level programming.
• Familiarity with microcontroller architectures, communication protocols (e.g., SPI, I2C, UART), securing IoT devices, and hardware/software integration.
• Proven experience migrating firmware across hardware revisions while preserving application-level behavior.
• Proficiency using AI tools to enhance productivity.
• Comfort working in real-world codebases that require refactoring, extension, and pragmatism rather than clean-slate rewrites.
• Experience with electronic test equipment, software debugging tools, emulators, and software version control systems.
• Knowledge of software development life cycle (SDLC) processes and methodologies.
• Attention to detail and commitment to delivering high-quality software solutions.

What You Need to Succeed:

• Comfortable operating in a fast-moving startup environment with incomplete information and evolving requirements.
• Able to balance speed and quality, knowing when to optimize and when to ship.
• Strong sense of ownership, you care deeply about the system working in the real world, not just passing unit tests.
• Clear communicator who can work cross-functionally without heavy process overhead.
• Willing to roll up your sleeves and solve problems wherever they appear.
• Strong analytical and problem solving skills.
