Qualifications
Work experience
MUST (Required Qualifications)
Ability to create development documentation (e.g., dimensional drawings, test reports) at a level that enables third-party reproducibility.
Ability to evaluate optical and electrical subsystems as an integrated system.
Experience with 3D CAD tools such as Fusion 360, SolidWorks, or FreeCAD.
Hands-on experience in end-to-end design, evaluation, and improvement of experimental systems that include both optical and electrical components.
Experience in quantification and process definition, and in compiling these into formal specifications.
Nice to Have (Preferred Qualifications)
Experience in designing, aligning, and stabilizing experimental optical systems (free-space and/or fiber-based).
Knowledge of quantum optics, interferometric measurement, and laser stabilization.
Deep technical expertise in the implementation of quantum repeaters.
Experience with EMI mitigation, low-noise circuit design, and thermal and vibration control.
Personality / Mindset
Ability to prioritize cost, reproducibility, and stability, and to choose practically viable implementation solutions over theoretically elegant but impractical research solutions.
Ability to articulate why a researcher-built experimental setup is unstable, and clearly explain the underlying causes.
Possesses deep technical understanding of demonstration or deployment target technologies, either through hands-on implementation or solid theoretical knowledge.
