The ideal candidate brings deep experience in optical engine firmware, defines ARM- and RISC-V-based control architectures, generates digital requirements for custom optical control ASICs, drives robust firmware development flow and CI, and mentors engineers across programs. The position is open for San Jose, CA or Woburn, MA. Responsibilities Architect, develop, debug, and release embedded firmware for optical engine platforms. Define MCU/processor, memory, boot, and peripheral requirements for optical module and optical engine control subsystems. Generate and own digital requirements and specifications for custom optical control ASICs, including control, telemetry, monitoring, interfaces, boot, memory, diagnostics, and testability. Partner with ASIC, RTL, verification, optical systems, and DSP teams to drive architecture definition, implementation alignment, bring-up, and debug. Develop firmware for PIC control algorithms and integrated photonic IC control functions; specify and integrate DAC/ADC requirements for control, monitoring, and calibration loops. Implement and maintain CMIS-compliant firmware for module control, telemetry, diagnostics, state management, and host interfaces. Lead firmware and digital bring-up for new optical module, optical engine, and control ASIC platforms. Develop firmware for manufacturing, test, screening, calibration, and production enablement, including calibration tables and calibration engines. Define and improve the firmware development flow, including build and release processes, automated testing, regression coverage, and continuous integration (CI). Drive root-cause analysis across lab bring-up, qualification, manufacturing, and field-return scenarios. Mentor engineers through technical leadership, design reviews, code reviews, and debug support. Main Requirements and Qualifications BS, MS, or PhD in Electrical Engineering, Computer Engineering, Computer Science, or related field. 7+ years of relevant experience for Senior Principal; 10+ years for Distinguished. Strong background in optical module firmware development, including optical engines. Proven experience defining embedded firmware architecture, including MCU/processor selection, memory sizing, boot, and peripheral requirements. Experience with ARM and RISC-V embedded architectures. Experience generating digital requirements for custom optical control ASICs. Hands-on experience with firmware and digital bring-up of complex hardware systems. Experience implementing CMIS for optical modules. Experience developing firmware for manufacturing, test, and calibration environments, including calibration tables and calibration engines. Strong knowledge of embedded interfaces, including I2C, I3C, SPI, MDIO, GPIO, etc. Experience specifying or using DAC/ADC devices for integrated photonic IC control. Strong proficiency in embedded C and low-level hardware/firmware debug. Experience establishing firmware development workflows and CI for embedded systems. Demonstrated success working cross-functionally with optical systems, DSP, ASIC, manufacturing, test, calibration, and reliability teams. Proven ability to mentor and develop engineers. Preferred Qualifications Experience with root of trust, secure boot, and secure firmware upgrade mechanisms. Experience leading architecture across multiple optical module, optical engine, or control ASIC programs. Experience supporting product qualification, reliability investigations, and failure analysis.
