Optical Engineer

RxSight® is an ophthalmic medical technology corporation headquartered in Aliso Viejo, California that has commercialized the world’s first and only adjustable intraocular lens (IOL) that is customized after cataract surgery. The company’s mission is to revolutionize the premium cataract surgery experience by allowing surgeons to partner with their patients to achieve optimized results for every unique eye.

RxSight is seeking a highly motivated and innovative Optical Engineer to join the IOL Development Group. The successful candidate will contribute to the development, characterization, optimization, and validation of next‑generation intraocular lens (IOL) technologies and related ophthalmic systems.

This position requires a strong foundation in optical engineering, ophthalmic optics, computational modeling, and experimental characterization. The Optical Engineer will work collaboratively with cross‑functional teams to develop innovative solutions that improve visual outcomes for cataract patients. Responsibilities include optical design, wavefront analysis, optical metrology, multiphysics modeling, finite element analysis (FEA), experimental validation, and data‑driven support of product development activities from concept through commercialization.

The ideal candidate combines hands‑on laboratory experience with strong analytical and computational modeling skills and is passionate about developing technologies that advance personalized vision correction.

This is a fully onsite position at our headquarters in Aliso Viejo, CA so candidates must reside in or near this city.

• Design, model, and evaluate intraocular lenses and ophthalmic optical systems using optical engineering principles and industry-standard software tools.
• Perform optical simulations, tolerance analyses, and sensitivity studies to optimize product performance.
• Analyze optical quality using metrics such as wavefront error, modulation transfer function (MTF), point spread function (PSF), Strehl ratio, and visual image quality metrics.
• Develop analytical methods to predict and evaluate clinical optical performance.
• Support optical optimization activities for existing and next‑generation ophthalmic products.

• Develop, validate, and maintain computational models used to support lens design, material development, and system‑level product performance.
• Create multiphysics models that describe interactions between optical, mechanical, thermal, diffusion, and material‑property phenomena.
• Perform finite element analysis (FEA) to evaluate lens deformation, stress distributions, dimensional stability, and implant behavior under physiological and manufacturing conditions.
• Model interactions between lens geometry, polymer material properties, diffusion processes, mechanical deformation, and optical performance.
• Correlate modeling results with experimental measurements and clinical observations to improve model accuracy and predictive capability.
• Apply simulation tools to support product design decisions, risk reduction, and process optimization.

• Design and conduct laboratory experiments to characterize optical performance of lenses, materials, and ophthalmic systems.
