Senior Optical Fibre Engineer

Responsibilities

• Use simulation and analytical tools to evaluate the behaviour and performance of advanced fibre designs and fibre-based optical systems
• Assess modal properties, loss mechanisms, dispersion, coupling, and other key fibre characteristics
• Design and execute experiments to measure, verify, and interpret fibre properties and subsystem performance
• Correlate simulation and experimental results to guide development decisions
• Work with external development partners to assess technical options and steer fibre design
• Translate system requirements into meaningful fibre performance targets
• Collaborate across photonics, systems, and experimental teams to support integration

Requirements

• PhD in photonics, optics, physics, engineering, or related field, or equivalent industry experience
• Significant experience in fibre optics, guided-wave photonics, or optical system development
• Strong understanding of advanced and specialty optical fibre behaviour
• Experience with optical simulation tools such as FDTD or related electromagnetic modelling methods
• Hands-on experience designing and executing experiments to characterize optical properties
• Experience analysing and reconciling modelling and experimental data
• Ability to operate independently in a hands-on R&D environment
• Strong communication skills for working with internal teams and external partners

Preferred Qualifications

• Experience with advanced or specialty fibre platforms
• Experience working closely with fibre development, fabrication, or research groups
• Experience in both modelling and experimental verification of fibre or waveguide performance
• Familiarity with demanding optical system environments prioritizing low loss
• Experience translating early-stage optical concepts into robust engineering outcomes
