Senior Optical Fibre Engineer

About the role

The Senior Optical Fibre Engineer will develop and evaluate advanced optical fibre for high-performance optical systems. This role involves a combination of optical modelling, design trade-off analysis, and hands-on experimental validation to translate performance requirements into practical technical direction.

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 relevant to demanding optical applications.
• Design and execute experiments to measure, verify, and interpret fibre properties and subsystem performance.
• Correlate simulation and experimental results to build understanding, validate assumptions, and guide development decisions.
• Work closely with external development partners to assess technical options, review results, and help steer fibre design and performance tradeoffs.
• Translate system or subsystem requirements into meaningful fibre performance targets and evaluation criteria.
• Collaborate across photonics, systems, and experimental teams to support integration of advanced fibre technologies into larger optical platforms.
• Contribute technical judgement to the down-selection, maturation, and validation of advanced fibre solutions
