Original job description

Requisition Number: 79596

The company built on breakthroughs. Join us.

Corning is one of the world’s leading innovators in glass, ceramic, and materials science. From the depths of the ocean to the farthest reaches of space, our technologies push the boundaries of what’s possible.

How do we do this? With our people. They break through limitations and expectations – not once in a career, but every day. They help move our company, and the world, forward.

At Corning, there are endless possibilities for making an impact. You can help connect the unconnected, drive the future of automobiles, transform at-home entertainment, and ensure the delivery of lifesaving medicines. And so much more.

Come break through with us.

Our Optical Communications segment has recently evolved from being a manufacturer of optical fiber and cable, hardware and equipment to being a comprehensive provider of industry-leading optical solutions across the broader communications industry.This segment is classified into two main product groupings – carrier network and enterprise network. The carrier network product group consists primarily of products and solutions for optical-based communications infrastructure for services such as video, data and voice communications. The enterprise network product group consists primarily of optical-based communication networks sold to businesses, governments and individuals for their own use. Scope of Position

The Prototyping Engineer helps design, build, and coordinate prototypes for optical connectivity solutions used in fiber optic networks. This is a hands-on role on a low-volume, development-oriented prototype team. The engineer works with technicians, engineering, Quality, Supply Chain, Manufacturing, and external suppliers. Customer interaction happens alongside a Senior Engineer or project lead.
The position turns defined product and customer needs into prototype designs, materials, tooling, assembly processes, and build plans. It does this under the guidance of senior team members. The engineer supports fiber optic connector and cable assembly development, process improvement, and technical troubleshooting. The engineer also helps hand off solutions to Technology Teams or manufacturing operations.
Projects may support any Corning division, customer opportunity, or R&D initiative. The engineer begins building an internal and external network of product experts, suppliers, fabrication shops, contract manufacturers, cable assembly houses, and tooling providers.

Day to Day Responsibilities

Collaborate with engineers, technicians, lab managers, suppliers, and supply chain to build and deliver prototypes for optical connectivity solutions. Support Market Development, Product Line Managers, and customers as directed.
Develop prototype designs, build plans, bills of materials, work instructions, process documentation, and acceptance criteria for defined project scopes. Contribute to schedules.
Execute technical work on fiber optic connector, cable assembly, and optical connectivity prototype builds and process-development trials. Lead smaller builds and support larger ones.
Work directly with technicians to give technical guidance, troubleshoot build issues, and clarify process requirements. Escalate complex issues to senior engineers.
Support development and improvement of processes for fiber optic components.
Help coordinate materials, tooling, fabrication, equipment, supplier activity, and prototype delivery timelines.
Design and improve fixtures, tooling, and workstations that support quality, safety, ergonomics, and process consistency. Senior engineers review the work.
Collect and analyze prototype build, inspection, test, yield, and defect data. Participate in root-cause analysis and corrective actions, and lead them on straightforward issues.
Provide design-for-manufacturability, assembly, testability, and reliability feedback to product and technology teams.
Support global manufacturing teams in assessing manufacturability and in technology transfer or initial process implementation.
Build relationships with internal experts and external fabrication, tooling, equipment, supplier, and contract manufacturing resources.
Capture prototype results, customer feedback, technical risks, and potentially patentable ideas.

Required Qualifications

BS in Mechanical Engineering
3-5 years of experience in a development, experimental laboratory, manufacturing, or comparable environment working with electrical/mechanical assembly and testing. Relevant internships, co-ops, and research or project experience qualify.
Mechanical aptitude and structured problem-solving ability.
Ability to learn, document, troubleshoot, and improve precision assembly or manufacturing processes.
Ability to interpret drawings, specifications, tolerances, bills of materials, travelers, and test or inspection data, or the willingness to develop this skill quickly.
Ability to communicate technical ideas clearly through written documentation, presentations, and direct interaction with technical teams.

Desired Qualifications

CAD design skills for products or manufacturing processes (ProE / Creo preferred, or other 3D CAD with willingness to learn).
Ability to interpret and begin generating drawings and schematics.
Basic familiarity with fiber optic theory, or interest in learning it.
Exposure to project management tools and practices.
Collaborates across the organization and contributes to technical culture.
Exposure to discrete assembly processing.
Exposure to developing processes and parameters, for example through coursework, internships, or lab work.
Collaboration with internal and external designers.

This position does not support immigration sponsorship.

The range for this position is $85,304.00 - $117,293.00 assuming full time status. Starting pay for the successful applicant is dependent on a variety of job-related factors, including but not limited to geographic location, market demands, experience, training, and education.
