Original job description

Lightmatter is leading the revolution in AI data center infrastructure, enabling the next giant leaps in human progress. The company invented the world’s first 3D-stacked photonics engine, Passage™, capable of connecting thousands to millions of processors at the speed of light in extreme-scale data centers for the most advanced AI and HPC workloads.

Lightmatter raised $400 million in its Series D round, reaching a valuation of $4.4 billion. We will continue to accelerate the development of data center photonics and grow every department at Lightmatter!

If you're passionate about tackling complex challenges, making an impact, and being an expert in your craft, join our team of brilliant scientists, engineers, and accomplished industry leaders.

Lightmatter is (re)inventing the future of computing with light!

About this job

Are you ready to do meaningful internship work on technology that is changing how AI systems are built? The System Level Test team owns the final at-speed test of our silicon photonics products. These are cutting-edge high-speed optical interconnects built to move data between the processors that power AI datacenters, where copper is running out of reach and light is taking over. We build the test methods, the automation, and the data behind the pass vs fail decision. This summer's project is a hands-on optical characterization and correlation study aimed at improving how our products are tested in production. You will work on real optical hardware in the lab, build the measurement automation, generate the data, and write the recommendation that decides whether the approach moves forward. The result will directly influence how our next products are tested.

Responsibilities:

Characterize a set of silicon photonics units on bench optical instrumentation, measuring output power, modulation amplitude, extinction ratio, and wavelength.
Build automation to run measurements, control the lab setup, and log results in a consistent, reusable data format.
Correlate unit measurements against a calibrated laboratory reference and quantify per-unit offsets and population spread.
Measure unit stability across time, temperature, and repeated re-insertion, and analyze repeatability and drift.
Deliver a feasibility and gap assessment with a clear recommendation, including the calibration and maintenance scheme needed for production deployment.

Requirements:

Currently enrolled in a Bachelor's program in Electrical Engineering, Physics, Optical Engineering, or a related field.
Coursework or project experience in at least one of: integrated circuit design, device or circuit characterization, or electrical or optical testing.
Hands-on experience with standard lab equipment such as oscilloscopes, multimeters, power supplies, or optical power meters, from coursework, research, or a prior internship.
Programming experience in Python or a similar language, including reading and plotting measurement data.

Preferred Qualifications

Research, lab, or prior internship experience in photonics or semiconductors.
Experience automating lab instruments (PyVISA, SCPI, or similar).
Familiarity with basic statistics: mean, standard deviation, repeatability, and gauge or measurement uncertainty.
Publications, projects, or open-source contributions related to the role.

Our internship hourly rates are a standard pay determined based on the position and your location, year in school, degree, and experience.

Hourly Rate in USD

$43 - $47 USD

Benefits

Comprehensive Health Care Plan (Medical, Dental & Vision)
Retirement Savings Matching Program
Life Insurance (Basic, Voluntary & AD&D)
Generous Time Off (Vacation, Sick & Public Holidays)
Paid Family Leave
Short Term & Long Term Disability
Training & Development
Commuter Benefits
Flexible, hybrid workplace model
Equity grants (applicable to full-time employees)

Benefits eligibility may vary depending on your employment status and location. 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.
