  • Overview

    We are seeking a Computational Physicist with a specialty in optics possessing a strong background in numerical simulations, particularly ray tracing simulations and multi-physics analysis of optical systems to join our development team. The successful candidate will play a lead role in design, development, characterization, and optimization of algorithms targeting specific customer applications, and will be responsible for developing the computational foundation of our current and future platforms for improved optical discrimination. The successful candidate must be able to work both independently and with multiple technical staff as required during product development. The candidate should be a confident, self-motivated computational physicist / scientist / engineer who can lead investigations to explore the properties of advanced algorithms, using state-of-the-art computational methods including Monte Carlo and related techniques, with a focus upon the parameterization of the contributions these phenomena make to imaging system performance. The candidate's experience should reflect an ability to do so with minimal technical supervision. The candidate should be prepared to author reports and publications, and to deliver presentations to share results with colleagues and customers.

    Responsibilities

    Primary tasks include developing computational algorithms to model the physical optics, exploring and developing computational algorithms to improve upon the imaging performance in real time imaging environments, establishing test methods and supporting test systems development, and reporting results in a concise and lucid format through written reports and presentations. A high commitment to both technical and software quality is mandatory. The successful candidate must possess strong communication skills, and enjoy analyzing and solving problems while working with customers and business development staff. Proficient verbal and written communication skills are essential to effectively collaborate in a team environment to present and explain technical information.
