Sr. Mixed-Signal Digital Architect

Lightmatter builds chips for artificial intelligence computing that leverages unique properties of light for efficient computing and communications. If you're a collaborative engineer or scientist who has a passion for innovation, solving challenging technical problems and doing impactful work...work like building the world's first optical computers, consider joining the team at Lightmatter!

We are hiring a Senior Mixed-Signal Digital Architect. The selected candidate will partner with external facing teams at Lightmatter and the internal engineering team to deliver groundbreaking products to the market. As an architect, you will provide detailed technical documents that describe what needs to be built to the engineering team. This will require a solid understanding of process technology, state of the art in chip design, and clear communication skills. You will represent the company externally at technical conferences as an example of our technical leadership.

In this role, you will be defining the (micro-)architecture of the digital circuits that enable a ground-breaking photonic-based communication fabric. Your work will not only enable the AMS/photonic devices at low-level but also enable the necessary interfaces with the firmware/software.

You will report directly to the Chief Scientist, but you will also work closely with our digital, analog, photonic, and software teams to define and optimize the features needed to improve the power, performance, and area (PPA) of the next generation product. We are particularly looking for someone with expertise in architecting digital circuits for enabling high-speed AMS (and preferably photonic).

Join a tight-knit team where each individual’s contributions directly influence the success of the company and product. You'll have the opportunity to build a new kind of computer from the ground up and to solve groundbreaking challenges along the way. Work with people who love to build and who thrive in technically diverse environments where great ideas are prioritized.

Key Responsibilities:

• Along with the rest of the architecture team, be the digital architecture owner of Lightmatter’s Passage product. 
• Architecting and specifying digital sections of complex AMS and photonic circuits. These circuits include SerDes, ADC/DAC, photonic modulators and detectors.
• Work closely with the RTL and DV teams to enable block-level implementation and verification, respectively.
• Actively collaborate with the analog & photonic engineering teams to provide a high-bandwidth, low-latency photonic interconnect solution.
• Author, review, and validate architectural specifications.
• Identify possible pitfalls or difficulties, as well as mitigation strategies, around the execution of the proposed architecture.

• 12 years of related experience with a Bachelors’ degree, or 8 years and a Masters’ degree in Electrical or Computer Engineering.
• In-depth knowledge of high-speed and power-efficient digital design flow.
• Proven track record of delivering successful mixed-signal silicon.
• Ability and desire to collaborate in a cross-disciplinary team.
• Demonstrated strong problem solving skills specifically pertaining to problems that do not have obvious solutions.

Preferred Qualifications:

• In-depth knowledge of digital circuit design in a high-speed analog/photonic link, including device bring up, control, and digital signal processing.
• Understanding of forward error-correction schemes.

• Comprehensive Health Care Plan (Medical, Dental & Vision)
• 401k matching
• 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
• Stock Option Plan

Base Compensation Range: $190,000 - $230,000. In accordance with the Colorado, California and New York law, the range provided is Lightmatter's reasonable estimate of the compensation for this role. Actual pay will be based on several factors including work experience, location and education.

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.
