Meridial is seeking an entrepreneurial Optics & Photonics Engineer to join as a core technical contributor on our multi-photon microscopy platform. This is a hands-on role spanning optical system design, prototyping, iterative development and maintenance in close partnership with our neuroscience and engineering teams. This role reports to the Director of Engineering. You will own the optical stack end-to-end — from ultrafast laser source to sample and detector — and play an active part in identifying and solving technical challenges as our platform grows in capability and ambition.

The position calls for substantial practical experience with multi-photon microscopy and the ability to engage deeply with custom optical design, including working directly with specialty manufacturers to specify and refine components beyond off-the-shelf solutions. It will also involve interfacing with expert contractors who have deep familiarity with specific aspects of our platform, so a genuine eagerness to learn quickly and apply that knowledge effectively is essential. More broadly, the ideal candidate will bring strong optical engineering fundamentals and a startup-friendly mindset that keeps development moving forward in a fast-paced build-and-iterate environment.
