Firmware Engineer

FIRMWARE ENGINEER

Every unit we ship runs bare-metal firmware that controls link bring-up, signal conditioning, real-time diagnostics, and fault recovery—firmware that must work reliably across thousands of deployed devices. We are seeking a Firmware Engineer to architect and implement the low-level software that pushes our optical hardware to its limits. You will own everything from bootloaders and device initialization to timing-critical signal control, adaptive link training, and production firmware validation.

RESPONSIBILITIES

• Architect and implement low-level firmware that controls all aspects of transceiver behavior, including link bring-up, signal conditioning, and real-time diagnostics
• Develop and tune algorithms for automatic eye opening, link training, and adaptive signal optimization under varying conditions
• Design robust boot, initialization, and fail-safe mechanisms, ensuring reliable startup and recovery across thousands of deployed devices
• Own firmware validation and release workflows, including automated test coverage, factory flashing procedures, and traceability of shipped code
• Interface directly with hardware teams to define control schemes for custom silicon, power management, thermal behavior, and I/O signaling
• Continuously optimize for performance, power, and reliability, pushing bare-metal systems to operate at the limits of the hardware platform

QUALIFICATIONS

• BS in Computer Science, Computer Engineering, Electrical Engineering, or related discipline
• Demonstrated experience bringing up real-time embedded systems from scratch
• Proficiency in C or C++ and Python
• Experience writing and optimizing high-performance drivers for I²C, SPI, ADC sampling, DMA, or similar protocols
• Familiarity with application development and distributed systems architecture in a Linux environment
• Strong first-principles problem-solving skills and a focus on designing bug-free, maintainable software
• Excellent written and verbal communication skills; able to work effectively in dynamic, cross-functional teams
• Willingness to work extended hours and weekends as needed

PREFERRED EXPERIENCE

• Experience reviewing hardware schematics and defining HW/SW interfaces
• Demonstrated expertise architecting and implementing high-performance DSP and signal-processing algorithms
• Hands-on familiarity with real-time operating systems, build systems, and hardware-in-the-loop testing
• Background in robotics, controls, or physical-systems integration
• Leadership experience mentoring engineers and driving complex firmware/software projects to completion
