Teams at Lumai

Own Lumai’s day-to-day IT environment, including device fleet management, machine builds, identity and access, software licensing, office networking, printers, meeting-room technology, onboarding, and offboarding. Resolve end-user issues across macOS and Windows, establish repeatable IT processes, maintain security and asset records, and automate repetitive workflows using scripts, custom agents, and API integrations.

Own dense, high-layer-count PCB layout from schematic handoff through fabrication release. Develop stackups, HDI structures, controlled-impedance routing, differential pairs, BGA breakouts, libraries, design rules, and manufacturing documentation. Translate SI/PI constraints into layout rules, conduct DFM/DFA/DFT reviews, manage revisions, and coordinate with fabricators and assembly houses. The role requires expert Cadence Allegro or equivalent Altium experience, production-proven high-speed board design, IPC knowledge, and advanced HDI and fine-pitch package expertise.

Own signal and power integrity for high-speed boards and packages. Perform pre- and post-layout channel analysis, SI/PI modeling, via and connector optimization, PDN design, and chip-package-board co-simulation. Correlate simulations with VNA, TDR, and oscilloscope measurements, evaluate materials and fabrication tolerances, and establish reusable methodologies, model libraries, and design guidelines for reliable high-speed hardware.
