Digital Architect

About the role

Lightmatter builds chips that enable extreme-scale artificial intelligence computing clusters. We are hiring a Digital Architect for high-speed photonic (mixed-signal) communication chips.

Responsibilities

• Responsible for the digital architecture from initial concept through high-volume production.
• Architect and specify system level digital designs integrating complex AMS and photonic circuits.
• These circuits include high-speed drivers and receivers, SerDes, ADC/DAC, photonic modulators and detectors.
• Work closely with test and validation engineers to validate hardware against simulation prediction.
• Actively collaborate with the RTL and DV teams to enable block-level implementation and verification, respectively.
• Author, review, and validate architectural specifications.

Qualifications

• 3+ years and a Masters’ degree in Electrical or Computer Engineering.
• Knowledge of power-efficient digital design flow for high-speed AMS electronics, preferably on photonic communication channels.
• Understanding of digital circuit design in a high-speed analog/photonic link, including device bring-up, control, and digital signal processing.
• Demonstrated strong problem solving skills specifically pertaining to problems that do not have obvious solutions.
• Demonstrated strong written and verbal communication skills.

Preferred Qualifications

• Ability and desire to collaborate in a cross-disciplinary team.
• Power user of multiple development tools, including CAD tools, SPICE simulators, IBIS-AMI simulators, and general programming languages (e.g., MATLAB or Python).
• Willing and able to learn quickly. Self-starter with a “no task is too big or small” attitude.
• Innovative and flexible; realizes that a one-size-fits-all approach will not always solve the problem at hand.
• Data-driven and analytical; translates numbers into actionable strategies.
• Process-oriented and programmatic: builds structure through processes that can be relied upon across the organization.
