Lightmatter is solving the problem of enabling next-generation AI and HPC workloads through the development of extreme-scale data center infrastructure using its 3D-stacked photonics engine, Passage™.
Requirements
5 years of related experience with a PhD, or 8 years with a Master's degree in Electrical Engineering, Computer Engineering, Physics, or related disciplines.
Highly proficient in digital and/or analog modeling in software.
2+ years of experience in Python, MATLAB, C++ or other scripting/coding language.
Familiar with hardware description and/or verification languages such as Verilog, VHDL, SystemVerilog, or VerilogA.
Expertise in verification and testing methodologies, including the development and execution of comprehensive hardware and software testing activities.
Experience with version control systems, particularly Git, and issue tracking tools like JIRA.
Experience with cocotb or other coroutine-based cosimulation testbench environment for verifying verilog, VHDL, verilogA and/or SystemVerilog using Python.
Responsibilities
Develop, enhance, and maintain models in digital, analog, and photonics domains.
Integrate and maintain a mixed-signal, co-simulation framework built on top of multiple simulators (e.g., Xcelium, Spectre, Python + cocotb).
Write and maintain code in Python and System Verilog to support modeling and simulation across multiple domains.
Develop automated testbenches and verification scripts using Python and HDL simulation framework.
Work closely with cross-functional teams, including design engineers, verification teams, and photonics specialists, to understand tool requirements and deliver effective solutions.
Provide technical support and troubleshooting for simulation tools, addressing issues promptly to minimize downtime.
Create and maintain comprehensive documentation for tool development processes, user guides, and technical specifications.
Other
5 years of related experience with a PhD, or 8 years with a Master's degree in Electrical Engineering, Computer Engineering, Physics, or related disciplines.
Tech lead experience, including gathering user requirements, planning sprints, and ensuring simulation tools meet the needs of design and verification teams, verifying value delivery to end customers.
Demonstrated strong problem solving skills, specifically pertaining to problems that do not have obvious solutions.
Excellent written and verbal communication skills.
Candidates should have capacity to comply with the federally mandated requirements of U.S. export control laws.
