Silicon, Hardware, & Photonics Engineering - Internship

The Engineering team at Lightmatter

The Engineering team at Lightmatter takes photonic computing from research to reality, overseeing silicon photonics manufacturing, system integration, and 3D Co-Packaged Optics (CPO) development across the full stack, from chip to rack-scale data center deployment.

Responsibilities

Depending on your background, you'll contribute to one or more of these areas:

• Photonics & Silicon Engineering — Support design and simulation of optical components and photonic interconnects that move data at the speed of light.
• Product Engineering — Help develop and run tests that validate silicon photonics products from the lab bench to manufacturable hardware.
• Analog — Assist in the design and verification of analog and mixed-signal circuits that drive and control photonic components.
• Laser Development — Contribute to the characterization and integration of laser sources powering Lightmatter's photonic interconnect fabric.
• Systems Engineering — Support board bring-up, lab validation, and system integration of Lightmatter's photonic computing platforms.
• Digital Design — Work on RTL development, modeling of photonics circuitry, and developing algorithms and control logic for cutting-edge photonic interconnect SoCs.
• Design Verification — Help build testbenches and run simulations to verify complex chip designs meet functional and performance targets.
• Physical Design — Synthesis and timing analysis with floor planning, place-and-route, or physical verification of ASIC blocks using industry-standard EDA tools.
• Firmware Engineering — Help develop low-level drivers, active laser control algorithms, and system-level telemetry to power photonic interconnect platforms.

Qualifications

• Pursuing or recently completed a BS, MS, or PhD in Electrical Engineering, Physics, Computer Engineering, or a related field.
• Hands-on experience through coursework, capstone projects, research labs, or past internships.
• Familiarity with at least one relevant tool — SolidWorks, ANSYS, ADS, Cadence.
• Curious, collaborative, and comfortable asking questions.
