Lightmatter
Location: San Jose, CA
Employment Type: Full‑time
Seniority Level: Mid‑Senior level
Analog Architect Lightmatter is leading the revolution in AI data center infrastructure, enabling the next giant leaps in human progress. The company invented the world’s first 3D‑stacked photonics engine, Passage™, capable of connecting thousands to millions of processors at the speed of light in extreme‑scale data centers for the most advanced AI and HPC workloads.
As an Analog Architect, you will spearhead pathfinding efforts and work on early prototypes of innovative analog and mixed‑signal solutions for Lightmatter’s next‑generation optical‑engine products. You will then work closely with the engineering team to take your ideas to high‑volume production. This role requires a deep understanding of high‑frequency systems‑on‑chip (SoCs), high‑speed (100+ Gbaud) serial and electro‑optic interfaces. The role also requires creativity, analytical skills, and clear communication skills. You may represent the company at technical conferences as an example of our technical leadership.
Responsibilities
Architect high‑speed (200 Gbaud and beyond) electro‑optical interfaces for Lightmatter’s next‑generation co‑packed optics (CPO) solutions.
Design next‑generation high‑speed DACs, linear drivers and TIAs in the latest FinFET process nodes.
Actively collaborate across disciplines—with electronics, photonics, and mechanical engineering teams—to specify the requirements and solutions for circuit blocks, SoCs, debug, and validation.
Collaborate with the product team to develop our future technological and product roadmap in the context of industry trends.
Work closely with test and validation engineers to validate hardware against simulation prediction to ensure high performance and high yield.
Publish and present novel ideas and participate in premier technical conferences.
Qualifications
A Ph.D. degree in Electrical Engineering or similar discipline with at least 5+ years of experience designing high‑speed analog circuits in TSMC N3/N5/N7.
Hands‑on experience in high‑speed SERDES design in advanced process nodes (7 nm and below).
Deep technical background and a proven track record of innovation in their area of expertise.
Strong understanding of how the layout impacts the SERDES performance.
Familiarity with analyzing the impact of package and PCB on SERDES performance.
Familiarity with UCIe, PAM4, and other high‑speed SerDes.
Strong background with using circuit and electromagnetic simulation tools needed for high‑speed mixed‑signal circuit design: Cadence virtuoso, Verilog‑A, EMX or equivalent tools.
Benefits
Comprehensive Health Care Plan (Medical, Dental & Vision)
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
Commuter Benefits
Flexible, hybrid workplace model
Equity grants (applicable to full‑time employees)
Salary Range: $200,000 USD - $280,000 USD (total compensation includes base salary, equity grant, performance‑based equity and other rewards).
Lightmatter recruits, employs, trains, compensates, and promotes regardless of race, religion, color, national origin, sex, disability, age, veteran status, and other protected status as required by applicable law.
Export Control: Candidates should have capacity to comply with the federally mandated requirements of U.S. export control laws.
Benefits eligibility may vary depending on your employment status and location.
