Firmware Engineer

FIRMWARE ENGINEERMesh 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.RESPONSIBILITIESArchitect and implement low-level firmware that controls all aspects of transceiver behavior, including link bring-up, signal conditioning, and real-time diagnosticsDevelop and tune algorithms for automatic eye opening, link training, and adaptive signal optimization under varying conditionsDesign robust boot, initialization, and fail-safe mechanisms, ensuring reliable startup and recovery across thousands of deployed devicesOwn firmware validation and release workflows, including automated test coverage, factory flashing procedures, and traceability of shipped codeInterface directly with hardware teams to define control schemes for custom silicon, power management, thermal behavior, and I/O signalingContinuously optimize for performance, power, and reliability, pushing bare-metal systems to operate at the limits of the hardware platformQUALIFICATIONSBS in Computer Science, Computer Engineering, Electrical Engineering, or related disciplineDemonstrated experience bringing up real-time embedded systems from scratchProficiency in C or C++ and PythonExperience writing and optimizing high-performance drivers for I²C, SPI, ADC sampling, DMA, or similar protocolsFamiliarity with application development and distributed systems architecture in a Linux environmentStrong first-principles problem-solving skills and a focus on designing bug-free, maintainable softwareExcellent written and verbal communication skills; able to work effectively in dynamic, cross-functional teamsWillingness to work extended hours and weekends as neededPREFERRED EXPERIENCEExperience reviewing hardware schematics and defining HW/SW interfacesDemonstrated expertise architecting and implementing high-performance DSP and signal-processing algorithmsHands-on familiarity with real-time operating systems, build systems, and hardware-in-the-loop testingBackground in robotics, controls, or physical-systems integrationLeadership experience mentoring engineers and driving complex firmware/software projects to completionCOMPENSATION AND BENEFITS:Pay range:Firmware Engineer: $140,000.00 - $170,000.00/per yearTitle 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.
