Summary: VIAVI (NASDAQ: VIAV) is a global provider of network test, monitoring and assurance solutions for telecommunications, cloud, enterprises, first responders, military, aerospace, and railway. VIAVI is also a leader in light management technologies for 3D sensing, anti-counterfeiting, consumer electronics, industrial, automotive, government and aerospace applications.About the RoleAs a Senior Firmware Developer at VIAVI Solutions, you will design, develop, debug, and maintain embedded firmware for the MAP modular optical test platform and its cassette ecosystem. The MAP platform is a rack‐mounted chassis hosting hot‐swappable optical test modules (cassettes) covering a broad range of fiber optic test and measurement applications.You will work across multiple cassette architectures as well as chassis‐level infrastructure including FPGA bridges, microcontrollers, and Linux kernel/driver integration.Key ResponsibilitiesCassette Firmware DevelopmentDevelop and maintain firmware for ARM‐based cassettes (embedded Linux, C/C++) and DSP‐based cassettes (uClinux, C/C++)Implement SCPI command protocol handlers for instrument control and measurement data acquisitionDevelop multi‐threaded real‐time signal processing pipelines using FFT, DSP, and SIMD optimizationsInterface with optical hardware components via I2C, SPI, UART, and USBFPGA Interfacing & DevelopmentInterface cassette firmware with FPGA co‐processors for signal processing, optical triggering, and hardware acceleration via memory‐mapped registersMaintain and enhance the MAP platform PCIe bridge FPGA (Verilog)



which provides bus translation between the host processor and cassette backplaneDebug FPGA register‐level interactions and timing issues across SPI and PCIe domainsMicrocontroller FirmwareDevelop firmware for bridge board microcontrollers (C) that manage FPGA programming, card‐present detection, I2C register interfaces, and chassis power sequencingMaintain power management microcontroller firmware controlling chassis power rails, standby/power‐cycle sequencing, and watchdog functionalityKernel & System‐Level WorkContribute to Linux kernel and device tree customization on the chassis controllerDebug and resolve hardware‐software integration issues including I2C bus contention, display pipeline conflicts, IRQ handling, and power managementDevelop and maintain system services, udev rules, and shell scripts for chassis lifecycle management (boot, hot‐plug, reboot, shutdown)Cross‐Functional CollaborationWork closely with hardware engineers on board bring‐up, schematic review, and signal integrity debuggingCollaborate with the software team on communication between cassette firmware and the web GUI / front panel applicationsSupport manufacturing with calibration firmware, production test scripts, and factory provisioning toolsLeverage AI‐augmented development workflows (e.G., AI coding assistants) to accelerate firmware development, debugging, analysis and unit‐testingRequired QualificationsBS or MS in Electrical Engineering, Computer Engineering,
