Top Tech Jobs & Startup Jobs

Research and model performance of Lightmatter-enabled hardware systems for ML training and inference. Build performance modeling tools, design rack-scale reference platforms, collaborate with product and engineering, publish academic and industry research, and act as the in-house ML systems expert.

Designs, tests, analyzes, integrates, qualifies, and documents mechanical hardware for AI server chassis and rack platforms. Responsibilities include CAD, drawings, BOMs, thermal and structural analysis, prototype builds, design reviews, root-cause investigations, contract manufacturer oversight, supply-chain coordination, and production scaling. The role focuses on electronics and photonics packaging, thermal management, manufacturability, and collaboration with cross-functional engineering and program teams.

The Staff Physical Design Engineer will implement digital blocks using advanced tech nodes, focusing on timing closure and power integrity, while collaborating with teams on ASIC design.

Implement and sign off complex digital blocks from synthesis through physical verification in advanced process nodes. Drive full-chip STA and timing closure, power analysis, floorplanning, IO and clock distribution, DRC/LVS cleanup, and functional/timing ECOs. Automate flows with TCL/Python/Shell, collaborate across teams, and work with EDA vendors to resolve tool issues.

The Photonics Technical Lead will create scalable laser solutions for silicon photonics AI communications, collaborating across teams to ensure design feasibility and meet performance specifications.

Lead development and qualification of silicon foundry processes for integrated photonic AI platforms. Define process flows, collaborate with foundries and design teams, establish yield and reliability metrics, and drive product tapeout through production and lifetime characterization.

Lead design verification for integrated digital, analog, and photonic devices using UVM, mixed-signal/AMS methods, RNM, and emulation. Define DV methodology, create reusable testbenches, run block and full-chip verification, integrate analog IP and behavioral models, close coverage and signoff, and collaborate with architects and designers for performance and post-silicon validation.

The Sr./Principal Mixed-Signal Digital Architect will design digital circuits for photonic-based communication, collaborate with teams, and lead product development.

The engineer will architect wafer, package, and system level characterization and test strategies for silicon photonics products, and work closely with architecture and design teams, vendors, and validation teams.

Develop high-speed analog transceiver solutions while collaborating with architects and engineers for optical communication systems.
