The Senior Firmware Engineer is responsible for designing, developing, verifying, and maintaining embedded firmware for advanced scientific imaging and automation instruments. The role supports shared and complementary embedded technologies across the imaging instrument platforms, including real-time control, precision motion, imaging hardware, communications, firmware updates, environmental control, diagnostics, and multi-board integration.

This position reports to the Software Engineering Manager and is part of the Engineering team located in San Jose, California. This is an on-site role supporting hands-on instrument development and integration.

In this role, you will have the opportunity to:

• Design and deliver production embedded firmware in C and modern C++ for STM32-based controllers, creating maintainable architectures for multi-board scientific instruments and board-specific applications.

• Lead hardware bring-up, subsystem integration, and performance optimization across motion, imaging, illumination, sensing, temperature control, and other instrument functions in partnership with electrical, mechanical, systems, test, application software, and manufacturing teams.

• Develop and troubleshoot real-time FreeRTOS and CMSIS-RTOS applications, including task scheduling, synchronization, queues, notifications, timers, interrupts, DMA, memory usage, and fault recovery.

• Implement reliable device communication and update capabilities, including peripheral drivers, framed host-device protocols, CRC-protected messaging, Ethernet/TCP services, embedded networking, bootloaders, flash programming, image verification, and persistent configuration.

• Strengthen product quality and technical execution by building unit, integration, hardware-assisted, and hardware-in-the-loop tests; maintaining build and continuous-integration workflows; leading design and code reviews; documenting interfaces and decisions; mentoring engineers; and driving root-cause analysis of regressions and field issues.

The essential requirements of the job include:

• Bachelor’s degree in Computer Engineering, Electrical Engineering, Computer Science, or a related technical discipline, or equivalent practical experience.

• 5+ years of professional embedded firmware development experience, including ownership of production systems through development, integration, release, and maintenance.

• Expert proficiency in embedded C and strong proficiency in modern C++ for resource-constrained microcontrollers, with practical experience on STM32 or comparable Arm Cortex-M platforms.

• Hands-on experience developing RTOS-based and non-RTOS embedded systems, including interrupts, DMA, timers, concurrency, memory constraints, and fault handling. Experience designing and maintaining hardware-facing firmware using UART, I2C, SPI, PWM, ADC/DAC, GPIO, Ethernet/TCP, or comparable interfaces. Ability to read schematics and datasheets and diagnose hardware–firmware interactions using oscilloscopes, digital multimeters, logic analyzers, and other standard bench tools.

• Demonstrated experience with code reviews, automated testing, technical documentation, and disciplined root-cause analysis for complex embedded products.

Travel, Motor Vehicle Record & Physical/Environment Requirements:

• Willing and able to travel up to 10%.
• Able to lift up to 50 pounds.

It would be a plus if you also possess previous experience in:

• Experience developing scientific instruments, microscopy systems, laboratory automation, imaging systems, or other complex electromechanical products.
• Experience integrating device drivers with application software.
