Firmware Engineer

Firmware Engineer Gardena, CA Mesh Optical Technologies was founded on the belief that optical photons will be at the center of advanced technologies in the coming century. Making advanced technology ubiquitous means building at scale, and that's exactly what we're doing at Mesh. 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 Compensation and Benefits: Pay range: Firmware Engineer: $140,000.00 - $170,000.00/per year Title and base salary are determined on a case by case basis commensurate with experience and merit. In addition to base salary, compensation for this role includes: Eligibility for long-term incentives including company stock options and discretionary bonuses awarded for exceptional achievements. Comprehensive medical, vision, and dental insurance with significant cost covered by the company for yourself and dependents. Paid parental leave and flexible PTO (3 weeks accrued vacation and 10 company holidays per year). 401(k) retirement plan access. Relocation assistance to sunny Los Angeles. Mesh Optical Technologies
