Quantum Experimental Scientist
Rotonium is expanding its quantum experimental team to advance the development and validation of on-chip photonic quantum technologies. For this reason, Rotonium is looking for a highly skilled Quantum Experimental Scientist (Mid/Senior) for a full-time position based in Padova (hybrid).
​​
The ideal candidate has strong hands-on experience with optical laboratory measurements, integrated photonics characterization, and free-space optical setups, and is motivated to work in a fast-paced environment at the intersection of quantum optics and photonic engineering.
Key Responsibilities
-
Perform optical laboratory measurements for the characterization of integrated photonic circuits and quantum photonic devices.
-
Set up and operate free-space optical experiments (beam splitters, mirrors, filters, polarization optics, etc.)
-
Perform fiber–chip coupling and alignment for on-chip characterization.
-
Use tunable lasers, detectors, and instrumentation for linear and nonlinear photonic measurements.
-
Develop automated measurement routines and data processing pipelines using Python.
-
Analyze datasets to extract device performance metrics and validate integrated photonic functionalities.
-
Collaborate closely with the PIC design, theory, and electronics teams to define experiments and interpret results.
-
Contribute to improving internal laboratory workflows, documentation, and measurement infrastructure.
Must-have
-
≥3 years of hands-on experience in optical laboratory measurements or experimental quantum optics.
-
University Master’s degree or PhD in Physics, Photonics, Optical Engineering, Quantum Technologies, or a related field (or equivalent experience).
-
Strong experience with:
-
Free-space optical components (beam splitters, mirrors, filters, waveplates).
-
Fiber alignment, chip coupling, and integrated photonics characterization.
-
Tunable lasers, detectors, power meters, and optical instrumentation.
-
Proven ability to design, execute, and troubleshoot complex optical setups.
-
Strong Python skills for data analysis, automation of measurements, and visualization.
-
Ability to work autonomously in the lab and manage experiments end-to-end.
-
Professional working proficiency in English.
-
Nice-to-have
-
Experience with quantum or nonlinear optical measurements (e.g., photon correlations, SPDC, SFWM, squeezing, interferometric measurements).
-
Familiarity with quantum photonics concepts relevant to integrated implementations.
-
Experience with integrated photonics platforms (SiN, SOI, TFLN).
-
Knowledge of electronics for experiment control and synchronization.
What We Offer
-
Full-time permanent position.
-
Hybrid working mode.
-
A role with direct impact on Rotonium’s quantum photonic roadmap and experimental validation workflows.
-
Fast-paced, collaborative environment working at the intersection of quantum optics and integrated photonics.
