Analog​/Mixed Signal Architect

Analog and Mixed-Signal (AMS) Architect

Lightmatter builds chips that enable extreme‐scale AI computing clusters. We are hiring an Analog and Mixed‑Signal (AMS) Architect who will partner with internal engineering teams to deliver groundbreaking products to the market. The selected candidate will provide detailed technical documents, model and analyze solutions, and represent the company at technical conferences.

• Propose innovative solutions for high‑speed (50 G and beyond) AMS circuit blocks custom to optical transceivers, such as drivers, TIAs, equalizers, ADC/DACs, PLLs, and CDRs.
• Work closely with the analog engineering design team to evaluate 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.

• Ph.D. 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, and IBIS‑AMI simulators.
• Ability and desire to collaborate in a cross‑disciplinary team.
• Excellent written and communication skills.
• Demonstrated strong problem‑solving skills for non‑obvious problems.

• Understanding of signal processing (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).
• A culture champion for Lightmatter, aligning with the company’s light‑hearted culture.
• Willing and able to learn quickly; a self‑starter with a “no task is too big or small” attitude.
• Innovative and flexible; recognizes that a one‑size‑fits‑all approach may not 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.

• Competitive base salary and total compensation that includes equity, annual performance‑based equity, and other rewards.
• Retirement Savings Matching Program.
• Life Insurance (Basic, Voluntary & AD&D).
• Generous Time Off (Vacation, Sick & Public Holidays).
• Paid Family Leave.
• Short‑Term & Long‑Term Disability.
• Training & Development.
• Flexible, hybrid workplace model.
• Equity grants (applicable to full‑time employees).
• Benefits eligibility may vary depending on employment status and location.
