• Detailed understanding of optical beam quality and aberration minimisation. 

• Experience with optical simulation tools (ANSYS Zemax preferred). 

• Experience using optical test equipment such as beam profilers, polarimeters, optical spectrum analysers, wavemeters, polarimeters, wave-front sensors and photodiodes. 

• Excellent written and verbal communication skills. 

Desirable Skills and Knowledge 

• Experience with design for beam stability in power, pointing, polarisation and phase. 

• Experience with laser beam distribution, modulation and delivery 

• Experience with imaging system design and camera selection 

• Experience with laser systems, micro-optics, photonically integrated circuits or metasurface components. 

• Understanding of tolerance requirements for optical components and mounts. 

• Experience with 3D CAD software (SolidWorks preferred). 

• Entrepreneurial drive, intellectual agility and personal eagerness to develop with the needs of the business. 

• Passion for solving complex problems and challenges in a highly technical and scientific environment. 

• Ability to work comfortably in a highly collaborative, cross-functional, team-oriented, and matrixed environment.
