Molex possesses a rich heritage in the optical industry. We provide the highest performing field‑proven optical connectivity solutions from components to assemblies, optoelectronics and integrated solutions. Continuous innovation in passive component function integration, miniaturization, and manufacturing automation, cutting‑edge optical interconnect technology and comprehensive optical, mechanical capabilities enable us to serve the needs of high‑density, high‑bandwidth, and flexible optical networks.

We serve large, global clients in telecom, datacom and medical industries in providing next‑generation optical interconnect product to support the growing need for data and communications.

We are developing optical connectivity solutions, optoelectronic solutions, wavelength selective solutions and fiber‑optic assemblies and arrays.

We are looking for a Senior Photonics Engineer with a strong focus on innovative design of optical systems. The Senior Photonics Engineer leads development of optical systems by generating optical design concepts, guiding new product development projects, solving design issues, optimizing the design for product performance, manufacturing processes, and reliability. This person must have a strong understanding of optical principles, optical design tools, materials, manufacturing processes, optical performance tests, and product reliability to lead the optical design effort.

As a principal member of the team and a lead optical designer, this position is responsible for all the optical aspects of a new product development as well as new technology development activities. This expertise will lead to the advancement of our products and services in the fields of optical communication.

What You Will Do
  • Innovation of optical design/architecture of optical fiber to photonic chip optical systems
  • Conduct thorough analysis of optical system requirements and specifications
  • Create, design and analyze optical architectures in Zemax, or other design tools
  • Plan and manage prototyping and characterization of optical designs including DOE plan, alignment plan, test coordination, data analysis
  • Utilize advanced simulation tools and modeling techniques to evaluate and optimize the performance of optical systems including free‑space optics and integrated photonics
  • Conduct experimental testing and validation of optical components, adhesives, and other related material used in our optical product systems
  • Generate technology development ideas for future product applications
  • Collaborate with multi‑disciplinary design teams to integrate optical systems with other hardware, materials and mechanical components
  • Mentor other engineers and cross‑functional groups on optical design and engineering
  • Develop new tools and techniques as needed to continuously improve our ability to model and understand optical designs accurately
  • Interface with vendors of fibers, materials, adhesives and components
  • Provide direct and indirect support for product managers, sales, business development managers and customers
Who You Are (Basic Qualifications)
  • Master's degree in Engineering, Physics, Photonics or related technical field. PhD. is plus
  • At least 5 years of industry experience with optical fibers, interconnects, and free-space optical design
  • Experienced in leading the development of free space optical systems
  • Extensive experience with optical simulation tools such as Zemax
  • Strong hands‑on experience with optical benchtops and fiber coupling techniques
  • Experience with optical system design for manufacturing, design and cost

For this role, we anticipate paying $175,000 - $225,000 per year. This role is eligible for variable pay, issued as a monetary bonus or in another form.

At Koch companies, we are entrepreneurs. This means we openly challenge the status quo, find new ways to create value and get rewarded for our individual contributions.
