4d•Onsite

About The Position

Serve on an engineering team designing, developing, and qualifying optical fiber submarine cable hardware, with emphasis on Undersea Network Element (UNE) cover assemblies. This includes welded cover structures that maintain pressure-boundary sealing integrity and electrical/optical pigtail interfaces required for system interconnection. The role supports new product development and introduction from concept through production ramp, custom project designs, sustaining engineering, continuous improvement, material analysis, and qualification testing. The engineer works with factory process and reliability engineers, manufacturing operators, program managers, and vendors to develop hardware for deep-water undersea environments.

Requirements

Bachelor of Science in Mechanical Engineering or Materials Science.
At least 6 years of mechanical engineering experience with a deep foundation in mechanics and analysis.
Experience with finite element, finite differences, and other analysis tools.
Experience with CAD tools such as Creo, SolidWorks, and ANSYS or similar.
Excellent written and oral communication skills.
Must be legally authorized to work in the United States; employment eligibility verification is required at hire. Visa sponsorship is not available.
A resume must be attached to the application.

Nice To Haves

A Master's degree is preferred.
Internal candidates should have 5+ years of experience.

Responsibilities

Perform development, analysis, and testing of UNE cover assemblies and opto-electric splice trays, including new product design, process development, documentation, and qualification.
Lead teams implementing New Product Development and Introduction programs for undersea cable and hardware from concept through production ramp.
Develop special cover assembly designs for custom projects requiring customer-defined opto-electric interconnections; interface with vendors and select components to meet network design requirements.
Perform structural analyses and corrosion protection studies of deployment structures for custom projects.
Drive production process improvements through Value Analysis/Value Engineering activities, including qualifying designs that reduce assembly time in areas such as cover assembly design, fiber splice, power conductor soldering, and cover closure.
Maintain and streamline existing undersea hardware drawings and documentation through Sustaining Engineering, including clarifying and restructuring drawing packages and reducing duplication.
Perform material analyses to validate designs for extreme environments, considering structural integrity, temperature resistance, leak tightness, thermal management, electrical insulation, and corrosion.
Collaborate with factory process engineers, reliability engineers, manufacturing operators, and program managers.
Create and conduct qualification testing programs for new undersea hardware designs.
Write clear, concise summaries of analyses, test results, and other work output.
Develop a comprehensive understanding of materials for structural integrity, manufacturability, and thermal management in deep-water undersea environments.
