Job description

About this Role

Lightmatter builds chips that enable extreme-scale artificial intelligence computing clusters. If you're a collaborative engineer or scientist who has a passion for innovation, solving challenging technical problems, and doing impactful work like building the world's first optical computers, consider joining the team at Lightmatter!

We are hiring a Digital Architect for high-speed photonic (mixed-signal) communication chips. The selected candidate will partner with 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. In this role, you will be defining the 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. We are particularly looking for someone with expertise in architecting digital circuits to enable high-speed AMS circuits, with a strong preference for someone with experience in photonic circuits.

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
  • 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.

This is not a complete listing of the responsibilities. It's a representation of the things you will be doing. 

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.
