Photonics Fabrication Process Engineer - SNSPD Nanofabrication Responsibilities As part of the Hardware Team, you will work with our established team of physicists and engineers to support existing efforts to improve the performance of photon number resolving (PNR) cryogenic detectors. In this role you will contribute your experience spanning cleanroom fabrication, thin‑film characterization and metrology, all aimed at fabricating state‑of‑the‑art superconducting nanowire single photon detectors (SNSPDs). You will join the Fabrication Process Engineering Team dedicated to the development and optimization of fabrication processes required to build Xanadu’s photonic quantum computing hardware. A key part of the role will involve travel within Canada for cleanroom development in partner facilities. In addition, you will interface with internal stakeholders to understand the critical performance requirements of the detector technologies you will be building. Required Qualifications Ph.D. in Physics, Engineering, Experimental Sciences, or related discipline Proven track record of 5+ years of cleanroom process development experience with a focus on device fabrication Experience operating cleanroom tools including photolithography, electron beam lithography, deposition (PVD, CVD), wet & plasma etching (ICP RIE), and characterization (AFM, SEM, ellipsometry) Knowledge of optical thin‑film stack metrology, characterization and optimization Experience developing cleanroom recipes and maintaining detailed process documentation Experience with statistical process control (SPC) Experience working in a collaborative team‑based development environment Ability to operate autonomously in a fast‑paced environment and manage multiple competing priorities Ability to travel between the University of Waterloo and McMaster University cleanroom facilities as needed; requires a valid driver’s license and reliable vehicle Preferred Knowledge and Experience 2+ years of postdoctoral or industry experience in Physics, Engineering, Experimental Sciences, or related discipline Hands‑on experience with CMP for planarization of thin films and multi‑layer device stacks Understanding of the physics of optical detector technologies, including superconducting devices Experience fabricating and working with cryogenic detectors or their applications, e.g., TES, MKID, or SNSPDs Experience writing Python code Experience with large data set analysis and statistical reporting Compensation Base salary: 120,000 - 180,000 CAD, commensurate with location and experience.
