Photon Source Engineer

Salary: £60,000‑£71,000 per annum.

Psi Quantum is seeking a Photon Sources Engineer to support the development of our rapidly maturing photon sources platform. In this role you will be responsible for exploring long‑term strategies to guide the development of photon sources and accompanying technologies, working closely with the rest of the team and other device designers. You will play a fundamental role in the down‑selection of future photon source technologies by combining innovative ideas with experimental data and rigorous model closure.

• Design and maintain computational tools required for modelling photon‑pair sources.
• Model and optimise nonlinear optical systems, validating models using experimental measurements.
• Collaborate with designers to identify clear paths forward to improved device performance.
• Generate detailed reports based on experimental findings, providing evidence to direct the development roadmap of photon source technologies.
• Design new experimental techniques for specialised photon source/material characterization.
• Assess the impact of photon‑source performance/requirements on the infrastructure of large‑scale photonic systems, identifying key technological gaps and how they might be overcome.

• PhD in Photonics, Physics, Electrical Engineering, or a related field.
• Strong experimental and theoretical background in integrated optics and nonlinear device characterisation.
• Proficiency in Python for experiment automation and data analysis.
• Proficiency in the use of COMSOL/Lumerical for modelling complex optical systems.
• Hands‑on experience with complex optical measurement setups.
• Some experience with fabrication would be useful for influencing design decisions.

• Knowledge of quantum optics and nonlinear optical systems.
• Familiarity with the design challenges of a photon‑generation platform.
• Experience with novel integrated photonic material platforms.
• Experience leading technical projects.
• Proven experience in computational thinking.
• Proven skill in Applied Physics.
• Experience with Mathematica would be beneficial but is not required.
