About the role

  • You will work closely with teams across electronics, manufacturing, test, packaging, and system validation to translate device-level results into robust system-level performance.
  • The hiring level and scope for this role will be calibrated to the selected candidate's experience and strengths.
  • Candidates with relevant PhD/postdoctoral exposure, as well as those with additional industry experience, are encouraged to apply.

Responsibilities

  • Own high-speed electro-optic characterization and validation of active photonic devices, circuits, and subsystems, including electro-optic phase shifters, switches, modulators, and related components.
  • The candidate will need to work across different test configurations, including wafer-level probing, connectorized photonic/electronic devices, packaged assemblies, and integrated builds incorporating photonic chips, PCBs, drivers, FPGAs, firmware, and related hardware.
  • Develop new characterization methods, automation tools, and analysis workflows as needed.
  • Collaborate closely with multidisciplinary teams across photonics, electronics, packaging, manufacturing, test, firmware, and system validation to help design, build, test, and improve high-performance photonic chips and assemblies.
  • Document measurement methods, calibration procedures, results, and conclusions clearly and rigorously.

Requirements

  • Experience with high-speed electro-optic measurements, including electro-optic S-parameters, high-speed waveform measurements, bandwidth, and related device- and circuit-level metrics.
  • Strong understanding of RF measurement concepts, including S-parameters, impedance matching, bandwidth, signal integrity, calibration, de-embedding, and measurement uncertainty.
  • Excellent written and verbal communication skills, with the ability to communicate technical results clearly to a range of audiences.
  • MS or PhD in electrical engineering, applied physics, optical engineering, photonics, or a related technical discipline. Industry experience is a plus.
  • Deep understanding of integrated photonic devices and circuits, including passive and active components such as waveguides, electro-optic phase shifters, switches, modulators, and related high-speed photonic devices.
  • Hands-on experience with standard RF, microwave, and optical test equipment, including oscilloscopes, signal generators, VNAs, high-speed probes, optical power meters, lasers, photodetectors, and related laboratory equipment.
  • Experience developing automated test systems, measurement scripts, data pipelines, or analysis tools for photonic, RF, or high-speed electro-optic characterization.
  • Strong data analysis skills, including data visualization, statistical interpretation of measurement results, and data-driven decision-making.
  • Ability to translate device requirements and experimental learning goals into clear test plans, execute measurements, analyze results, and communicate conclusions.
  • Understanding of photonic-electronic interfaces and integrated build architectures, including PCBs, RF interconnects, high-speed drivers, FPGAs, TIAs, firmware-controlled test systems, wirebonds, and related electronics, is a plus.
  • Experience designing, simulating, or modeling photonic and electro-optic components using tools such as Ansys Lumerical, Tidy3D, COMSOL Multiphysics, Meep, or similar platforms is a plus; experience with RF or high-speed electronic simulation tools such as HFSS, ADS, Cadence AWR, or SPICE-based tools is also a plus.
  • Able to work independently with limited direction while maintaining strong alignment with project goals and cross-functional priorities.
