Zusammenfassung

Lightmatter is hiring a Digital Design Engineer to develop an ASIC for AI computing architectures. You will collaborate with world-class scientists and engineers to deliver RTL modules, achieve high-performance, low-power digital designs, and integrate silicon photonic concepts into accelerator designs.

The role requires a Bachelor’s in ECE with 5+ years in ASIC/HS design, SV/Verilog proficiency, and strong debugging of complex logic.

Qualifikationen

• Bachelor’s degree in Electrical or Computer Engineering (or related fields)
• At least 5 years of experience in ASIC design or similar high-speed chip design with multiple successful tape outs
• Proficiency in SystemVerilog or Verilog for digital logic design
• Proven experience debugging complex logic and mixed-signal simulations using industry-standard EDA tools (e.g., Synopsys VCS, Cadence Xcelium, Questa, or equivalent)
• Demonstrated track record of delivering high-performance, low-power digital designs in advanced semiconductor process nodes

Aufgaben

• Develop RTL (i.e. system Verilog) modules with DFT considerations for IC development
• Debug complex logic and mixed signal simulations
• Understand and integrate silicon photonic communication and compute technology into digital accelerator design
• Actively work with Architecture, Design Verification, Physical Design, Photonic, Analog and Software teams to realize high performance, low power designs in advanced technology nodes
• Create design specifications and documentation to facilitate collaboration with partner teams
• Generate documentation for modules, including functionality and timing
• Manage RTL implementation to achieve functionally correct, performant designs within project schedules by identifying, communicating and mitigating risks.
