Scientist II, Silicon Photonics
Cambridge, MA$128k - $170kfull-timePosted 1mo ago
About the role
Scientist II focused on building measurement, analysis, and data-quality foundations for electro-optic materials and silicon photonics devices. Owns characterization from thin-film material properties to electro-optic modulators at chip and wafer levels, and collaborates with simulation and ML teams to turn measurements into trusted data and scalable infrastructure.
Responsibilities
- Own characterization spanning thin-film material properties, passive photonic structures, and electro-optic modulators, at chip and wafer level.
- Define measurement strategies that produce reliable, decision-grade material and device performance data.
- Design, assemble, calibrate, and debug optical and optoelectronic test setups.
- Create measurement methods for novel thin film materials where no standard protocol exists, with calibration and quality-control practices that make results comparable across material variants and process conditions.
- Develop wafer-level measurement approaches that provide statistical insight into material and process variation and accelerate design iteration.
- Analyze data through material properties, device physics, process variation, and measurement uncertainty.
- Feed characterization results back into material, design, and fabrication decisions, and partner with simulation and ML teams.
- Prototype measurement methods for the automation team to scale into reliable infrastructure.
- Document procedures, data standards, and measurement limitations clearly for cross-functional teams.
Qualifications
- PhD in Electrical Engineering, Applied Physics, Materials Science, or a related field.
- Hands-on experience characterizing photonic materials and devices at chip and wafer level, spanning thin-film and material-level measurements through passive and active device testing.
- Experience measuring thin-film optical and electro-optic properties, including extraction of electro-optic coefficients.
- Experience testing passive photonic structures such as waveguides, resonators, and couplers, including loss and dispersion characterization.
- Experience with electro-optic modulators or related active integrated photonic devices.
- Experience building and debugging optical and optoelectronic measurement setups, including alignment, calibration, and noise control.
- Experience developing measurement methods where no standard protocol exists, including defending measurement validity and data quality.
- Experience interpreting data through material properties, device physics, process variation, measurement uncertainty, and repeatability.
- Familiarity with high-speed RF/electronics, fiber optics, and electro-optic testing workflows.
- Proficiency in Python, MATLAB, or an equivalent language for automated workflow and data analysis, and collaboration with ML and automation teams.
- Ability to work across design, fabrication, simulation, and automation teams while owning the measurement-quality standard.
