Principal Mechanical Engineer (5713)

SubCom • Newington, NH

2d • Onsite

About The Position

Work as part of the engineering team focused on the design and development of optical fiber submarine cable hardware product development, with special focus on the exterior of undersea network elements (UNEs), including the external protective structure (pressure housings, covers, cones, and pressure seals) and interconnectivity components (electrical/optical pigtail).

Requirements

• Bachelor of Science in Mechanical Engineering or Materials Science is required, Master’s is preferred.
• Minimum of 12 years of mechanical engineering experience with a deep foundation in mechanics and analysis.
• Experience in Finite Element, Finite Differences and Other Analysis tools.
• CAD tools such as Creo or SolidWorks, and experience with ANSYS (or similar) is required.
• Excellent communication skills, both written and oral.

Responsibilities

• Perform development, analysis, and testing of undersea hardware for opto-electric Undersea Network Element (UNE) housings, covers, cones, seals, and pigtails. Includes new product design, process development, documentation, and qualification.
• Lead teams in the implementation of New Product Development and Introduction (NPDI) programs for undersea cable and hardware from the concept phase through to production ramp.
• Maintain existing undersea hardware designs through Sustaining Engineering. Includes providing support to Manufacturing and performing Value Analysis/Value Engineering (VAVE) activities to maximize the functionality of designs while driving down overall cost.
• Perform material analyses to support designs for extreme environmental condition applications with special consideration for structural integrity, extreme temperature resistance, leak tightness, thermal management, electrical insulation, corrosion, etc. Materials include, but are not limited to, beryllium copper, copper, steel, and polyethylene.
• Perform Finite Element Analyses in support of the SubCom Design community. Analyses may focus on issues such as mechanical stress, high voltage electrical fields, thermal performance, and may relate to other mechanical areas of undersea systems, such as joints, cable, etc.
• Advise department engineers on best practices for FEA simulations by establishing standardized workflows, conducting technical workshops, and providing general guidance.
• Work collectively with a team of diverse professionals including factory process engineers, reliability engineers, manufacturing operators, and program managers.
• Create and perform undersea hardware qualification testing programs of new designs.
• Write clear and concise reports with summaries of analyses, test results, and other work output.
• Demonstrate a comprehensive understanding of various materials as pertaining to structural integrity, manufacturability, thermal management, and longevity for high reliability products in deep water undersea environments.
• Exhibit a deep knowledge of high-pressure test systems, TIG welding, brazing, x-ray equipment, Helium leak detection equipment and operation, polyethylene molding, etc.

Benefits

• SubCom offers a comprehensive benefits package, including but not limited to: competitive salaries, medical, dental, vision, life and disability insurance coverages, FSA, HSA, generous vacation, paid sick leave, paid parental leave, paid holidays, tuition reimbursement, adoption assistance, and a 401(k) plan with generous company match.
