Principal Digital Architect

The role

The Principal Digital Architect will define the architecture of digital circuits for a photonic-based communication fabric. This role involves providing technical documents, collaborating with cross-functional teams, and managing the digital architecture from concept through high-volume production.

What you will do

• Be the digital architecture owner of Lightmatter’s Passage product.
• Responsible for the digital architecture from initial concept through high-volume production.
• Lead direct collaboration with top tier semiconductor customer(s) at the system architecture level.
• Architect and specify system level digital designs integrating complex AMS and photonic circuits.
• Collaborate with the product team to develop future technological and product roadmaps.
• Work closely with test and validation engineers to validate hardware against simulation prediction.
• Collaborate with the RTL and DV teams to enable block-level implementation and verification.
• Author, review, and validate architectural specifications.
• Provide architectural direction to RTL, DV, analog, photonics, and firmware teams.
• Own digital control architecture for AMS and photonic circuits.

Required qualifications

• 12+ years and a Masters’ degree in Electrical or Computer Engineering
• In-depth knowledge of power-efficient digital design flow for high-speed AMS electronics
• Proven track record of delivering successful high-volume silicon in the market
• Proven understanding of silicon product development flow
• Demonstrated ability to ramp quickly into new domains and drive toward clarity with incomplete information
• Hands-on RTL development experience for AMS control logic, state machines, and interface blocks
• Device bring-up, closed-loop control, and DSP experience required
• Strong problem solving skills for problems without obvious solutions
• Strong customer communication

Nice to have

• Photonic circuit experience
• Experience with SoC architecture, including digital interfaces, configuration networks, embedded processor subsystems, and debug infrastructure
• Experience with hardware-software co-design
• Power user of multiple development tools, including CAD tools, SPICE simulators, IBIS-AMI simulators, and general programming languages (e.g., MATLAB or Python)
• Ability and desire to collaborate in a cross-disciplinary team
• Willing and able to learn quickly
• Self-starter with a “no task is too big or small” attitude
• Innovative and flexible
• Data-driven and analytical
