Silicon Validation Engineer

What MatX Is Building MatX is on a mission to be the compute platform for AGI. We are developing vertically integrated full-stack solutions from silicon to systems including hardware and software to train and run the largest ML workloads for AGI. MatX is seeking silicon micro-architects and design engineers to join our team as we create best-in-class silicon for high-performance and sustainable GenAI. Successful candidates for these roles will be responsible for delivering performant and functionally accurate silicon for MatX products across compute, memory management. High-speed connectivity and other key technologies. What You'll Do Here Own silicon bring-up and validation from first power-on through feature validation and production readiness. Develop and execute validation plans for chip-level and SiP-level functionality, performance, reliability, and system behavior. Validate boot, reset, initialization, power management, recovery, memory, interconnect, high-speed interfaces, and package-level functionality. Work across Top-level DV, Palladium emulation, lab validation, and package validation to improve coverage and correlation between environments. Debug complex failures using logs, registers, traces, waveforms, firmware output, and lab equipment. Analyze issues across RTL, firmware, software, board, package, and silicon boundaries. Collaborate with architecture, design, DV, emulation, firmware, software, and product engineering teams. Define observability and debug requirements and improve validation automation, execution, and failure triage. Who You Are Strong hands-on experience in silicon validation, post-silicon bring-up, hardware emulation, Top-level DV, or a related field. Experience validating complex SoCs, accelerators, or highly integrated silicon products. Strong understanding of digital hardware, SoC architecture, and hardware-firmware interaction. Proven ability to debug complex cross-functional failures and drive them to root cause. Experience working with real silicon and lab platforms. Familiarity with firmware, embedded software, drivers, and low-level hardware access. Ability to read and understand C or C++ code for debug purposes. Python or similar scripting experience. Ability to read specifications, register descriptions, validation plans, and relevant RTL. Strong ownership, communication, and cross-functional collaboration skills. Bonus Points If You Have Experience with both pre-silicon and post-silicon validation. Experience with Cadence Palladium. Experience with SystemVerilog, UVM, assertions, coverage, or waveform debug. Experience bringing up first silicon. Experience with HBM, DDR, PCIe, CXL, Ethernet, die-to-die interfaces, or advanced packaging. Familiarity with JTAG, oscilloscopes, logic analyzers, or protocol analyzers.
