Active Electrical Cable Module Firmware Engineer – Tech Lead

• Smart Cable Module Firmware
• Architect, develop, optimize, and maintain production-quality MCU firmware for smart cable modules.
• Implement firmware in C on ARM-based STM32 or comparable microcontroller platforms using RTOS-based designs.
• Develop Python scripts and tools for test automation, configuration, characterization, manufacturing test, and data analysis.
• Module Control, Telemetry, and Link Management
• Implement firmware for module power, thermal behavior, device configuration, signal conditioning, calibration, and upgrade.
• Develop management, telemetry, diagnostics, fault-handling, and health-monitoring features for manufacturing and field deployments.
• Integrate firmware with retimers or signal-conditioning devices, drivers, ADCs, DACs, sensors, and hardware control interfaces such as I2C and SPI.
• Bring-Up, Debugging, Validation, and Quality
• Lead MCU, board, and module bring-up, including boot-sequence development, peripheral initialization, hardware diagnostics, and root-cause analysis.
• Debug firmware and system behavior to resolve issues across hardware, firmware, control algorithms, and high-speed links.
• Partner with electrical, systems, validation, ASIC FW, and manufacturing teams to characterize, tune, and qualify smart cable modules.
• Establish unit-testing strategies and maintain automated tests that improve firmware quality, coverage, and release confidence.
• Apply disciplined version-control, code-review, documentation, and release practices throughout the development lifecycle.

• Bachelor’s degree in Electrical Engineering, Computer Engineering, Computer Science, or a related technical field.
• 5–10 years of experience developing embedded firmware or software for smart cables, networking, communications, semiconductor, or other high-reliability products.
• Strong programming skills in C and Python, with experience developing software for ARM-based STM32 or comparable microcontroller platforms.
• Experience with RTOS-based embedded development, embedded programming methods, hardware interfaces, and low-level device control.
• Proven experience with unit testing, version control, debugging, and hardware bring-up.
• Understanding of high-speed electrical physical-layer concepts, including signal integrity, channel behavior, equalization, and link training.
• Ability to analyze and resolve complex problems across firmware, hardware, control algorithms, and system-level behavior.

• Experience with active electrical cables, active copper cables, retimers, signal conditioners, optical modules, or related connectivity products.
• Experience with CMIS or other module-management standards, including telemetry, diagnostics, monitoring, and control requirements.
• Knowledge of high-speed link behavior, equalization, thermal management, power sequencing, and module calibration.
• Familiarity with JTAG, oscilloscopes, logic analyzers, protocol analyzers, and high-speed electrical test equipment.
• Demonstrated technical leadership, strong cross-functional collaboration, and the ability to drive an ambiguous problem from concept to production.
• Ability to work effectively with geographically diverse teams across different time zones.

Base salary range is $169,000 to $200,000 depending on experience, level, and business need. This role may be eligible for discretionary bonus, incentives and benefits.
