About the Role We are looking for a highly skilled and experienced Senior Laser Engineer to help in designing, developing and optimising an integrated system for writing and reading encoded information using laser. The ideal candidate will possess strong hands-on experience with class 4 Nd:YAG nanosecond pulsed laser operation, frequency doubling, laser optics, polarisation control, beam shaping, combined with computer skills to automate optical components control using software. You will join a small, interdisciplinary team and play a central role in advancing a next-generation optical security and sensing technology platform. Key Responsibilities Design and implement optical setup for encoding and retrieval of information using laser writing. Develop and characterise laser writing in a range of materials using nanosecond-pulsed Nd:YAG laser in a variety of optical ranges (266 nm / 532 nm / 1064 nm). Lead a small team to build and align free-space optical systems involving apertures, waveplates, galvo mirrors, beam splitters, illumination filters, spatial light modulators, detectors, and scanning stages. Create algorithms and control software for: Spatial light modulators Laser pulse triggering and modulation Galvo and waveplates control Develop calibration and characterisation procedures for optical components and detectors. Perform experiments to measure laser-written signatures, contrast, and stability. Document optical designs, test results, safety protocols, and build procedures. Contribute to IP development, patent drafts, and design reviews. Qualifications
