Lightmatter The Silicon, Hardware, & Photonics Engineering Intern at Lightmatter contributes to photonic computing development across design, testing, and integration. Interns support areas such as photonics engineering, analog design, laser development, and firmware engineering.

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.
