Hardware Test Engineering, Intern (Summer 2027)
$43 USD hourly
Originally posted 13 November 2026 by the employer.
About the role
The System Level Test team owns the final at-speed test of Lightmatter's silicon photonics products. This internship focuses on a hands-on optical characterization and correlation study to improve production testing for high-speed optical interconnects.
What you'll do
- 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.
What you'll need
- 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.
Nice to have
- 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.

How we counted: 667 open Silicon Test Engineering (DFT Test) roles from 85 employers tracked in the SemiconductorJobs index, counted 13 Nov 2026. Specialty figures count only roles carrying this exact specialty label, so an employer's related work in neighbouring specialties is not included there, and is counted in the wider Silicon Validation & Test family row. Days are counted from when our index first saw each posting, not from the employer's original posting date.
