At d-Matrix, we are focused on unleashing the potential of generative AI to power the transformation of technology. We are at the forefront of software and hardware innovation, pushing the boundaries of what is possible. Our culture is one of respect and collaboration.
We value humility and believe in direct communication. Our team is inclusive, and our differing perspectives allow for better solutions. We are seeking individuals passionate about tackling challenges and are driven by execution. Ready to come find your playground? Together, we can help shape the endless possibilities of AI.
d-Matrix is looking for a Staff Analog Design Engineer to lead analog-mixed signal IC design for our next-generation AI inference accelerators. This role owns circuit design for two critical subsystems: our in-memory-compute engine and the die-to-die serial interface that enables scale-out. You will drive design from schematic through silicon bring-up, guiding layout engineers working in deep sub-micron process nodes (7nm and below) and ensuring designs meet low-power performance targets across process-voltage-temperature corners. You will partner closely with layout engineers, backend/digital integration teams, and cross-site colleagues to deliver silicon-ready designs. This is a high-impact role for someone who wants to shape the analog foundations of state-of-the-art AI hardware.
Design analog-mixed signal circuits using industry-standard tools such as Cadence and Synopsys
Develop schematic-level circuit designs and conduct system-level performance analysis
Build test benches to support simulation and verification, including Monte Carlo yield analysis across PVT corners
Guide layout engineers on circuit layout in deep sub-micron process nodes (7nm and below), including hands-on minor layout adjustments as needed
Partner with backend engineers to integrate design and layout, and provide circuit models to support backend verification
Support testboard design for silicon bring-up, bench debug, and characterization
Build scripts to support silicon bring-up and test feature validation
BS, MS, or PhD in Electrical Engineering with 5+ years of related professional experience in high-speed circuit design (e.g., phase interpolators, clocking, PLL design)
Experience with schematic capture, SPICE simulation, and Monte Carlo simulation
Experience with circuit layout, extraction, and back-annotated simulation
Experience with channel modeling using MATLAB or similar tools
Strong cross-functional communication and collaboration skills, with the ability to work effectively across distributed, cross-site teams
Strong analytical and problem-solving skills, with the ability to manage multiple priorities in a fast-paced environment
We'd be excited about candidates with deep expertise in any one of the following areas:
SerDes verification & characterization — building/maintaining analog verification infrastructure (testbenches, regressions, Monte Carlo campaigns), migrating blocks across process nodes, or reliability analysis (EM, IR drop, ESD/latch-up)
Clocking & CDR — ownership of a low-jitter PLL, phase interpolator, or CDR loop through silicon at 25 Gbps+ per lane, including bang-bang/baud-rate/DSP-assisted CDR architectures
TX/RX datapath — high-speed driver or receive front-end design (CTLE, VGA, samplers), DFE/FFE equalization, or PAM4/DSP-based receiver architectures
Die-to-die interconnect experience (UCIe, BoW, or proprietary D2D PHY), familiarity with relevant specs (OIF CEI-112G/224G, IEEE 802.3, PCIe Gen6/7), or standards body participation
