Photonics Test Engineer - TFLN Platform (Toronto)

Your Role And Responsibilities

Architect and develop advanced experimental test procedures, assembling and automating the necessary hardware to characterize active optical devices. Drive the comprehensive characterization of various electro-optic components—with a primary focus on the thin-film LN platform—including electro-optic modulators (EOMs), tunable phase shifters, and beam splitters within our Photonic Integrated Circuits (PICs).Directly interface with the design, fabrication, instrumentation, and tooling teams to align, define, and execute strategic roadmaps toward successful device characterization. Define rigorous measurement and qualification routines for our devices, acting as the central hub for analyzing performance data and exchanging actionable insights with company stakeholders.Plan and execute our roadmap for testing activities in lockstep with development teams, keeping a strong vision toward future production requirements and scaling test procedures from the lab to High-Volume Testing. Evaluate emerging test methodologies in the photonics space and continuously optimize our characterization capabilities within a dynamic and challenging professional environment.Basic Qualifications And Experience

MSc degree in Electrical Engineering, Physics, or related field. 1+ years experience as a testing or product engineer of electro-optical devices and/or circuits products/wafers in a professional setting. Extreme attention to detail and a systematic approach to experimentation, with a focus on minimizing both systematic and statistical errors.Deep understanding of the characteristic properties of the TFLN as a material and the physics governing active photonic devices in this platform. Proven experience testing integrated photonic devices (EOMs, phase shifters etc.) at both chip and wafer scale. Performed high-frequency characterization and bias drift analysis on integrated modulators.Proficiency in Python for instrument control and experience with standard lab equipment (SMUs, OPMs, oscilloscopes, VNAs, LCR meters). Experience handling complex experimental datasets, including fitting to models, refining simulations, and performing rigorous error analysis. Ability to operate independently in a fast-paced environment and manage multiple competing priorities.Preferred Qualifications And Experience

Ph.D. thesis in the field of electro-optical characterization of semiconductor devices. 2+ years experience as a testing or product engineer of electro-optical devices. Practical experience with ISO 17025/9001 frameworks, specifically regarding measurement traceability and the creation of uncertainty budgets.Proficiency in gauge R&R and ANOVA to validate test station stability and isolate device performance from setup-induced noise. Experience working with commercial test solutions (e.g., FormFactor, Ficontec, MPI) and scaling R&D procedures for production environments. Understanding of sources of loss in photonic devices and their relation to fabrication processes. Experience in TCAD/COMSOL simulations for semiconductor devices to correlate physical models with experimental data. Base Salary and Benefits
