Analog/Mixed Signal Architect

About the role

Lightmatter builds chips that enable extreme-scale AI computing clusters. We are hiring an Analog and Mixed-Signal (AMS) Architect.

Key Responsibilities

• Propose innovative solutions high-speed (50G and beyond) AMS circuit blocks custom to optical transceivers, such as drivers, TIAs, equalizers, ADC/DACs, PLLs, CDRs.
• Work closely with the analog engineering design team to performance, power, and area estimates of the analog devices within Passage.
• Actively collaborate with the photonics engineering team to provide a high-bandwidth photonic interconnect solution.
• Author, review, and validate architectural specifications.

Qualifications

• PhD in electrical engineering, physics, applied physics, or a discipline related to analog design.
• Experience in designing and testing optical front-end receivers and transmitters (TIAs, drivers), CTLE, DFE, ADC, DAC, oscillators, etc. in advanced CMOS.
• Power user of simulation tools Cadence Virtuoso, Cadence Spectre, Verilog-A, IBIS-AMI simulators.
• Able and willing to collaborate in a cross-disciplinary team.
• Excellent written and communication skills.
• Demonstrated strong problem-solving skills specifically pertaining to problems that do not have obvious solutions.

Preferred Qualifications

• Understanding of signal processing (i.e., equalization, digital signal processing, and coding) and signal integrity in optical communication.
• Experience in silicon photonic devices (Mach-Zehnder and microring modulators, thermally tuned components).
