Silicon Intern - Hardware & Photonics Engineering

## 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.
