• Conduct feasibility studies, engineering calculations, design analyses, tolerance evaluations, prototype development, and design verification to assess cable performance and manufacturing feasibility.
• Apply advanced engineering principles to optical cable construction, mechanical performance, materials selection, and environmental durability; evaluate polymers, strength members, water-blocking materials, coatings, and jacketing systems.
• Develop and execute mechanical, optical, thermal, environmental, and reliability test plans; evaluate prototypes against applicable ICEA, Telcordia, IEC, customer-specific, and internal performance requirements; analyze results and document conclusions.
• Independently manage technical aspects of assigned product development and New Product Introduction projects, including schedules, deliverables, technical risk, design reviews, issue resolution, and engineering documentation.
• Collaborate with Manufacturing, Process Engineering, suppliers, and Quality on manufacturing samples, production trials, process compatibility, scale-up, and implementation; improve capability, quality, cost, and yield.
• Support customer evaluations, product qualifications, demonstrations, field trials, new product introductions, production ramp-up, and commercialization; coordinate technical activities with suppliers and external testing organizations as needed.
• Investigate and resolve material performance, mechanical reliability, and manufacturing compatibility challenges through failure investigations, root-cause analysis, and corrective action; support Manufacturing and Quality with product and process troubleshooting.
• Maintain accurate design records, engineering drawings, technical reports, test results, product specifications, engineering changes, laboratory equipment records, and calibration documentation.
• Serve as a technical resource for cable development, testing, qualification, and product-related challenges; provide design reviews, mentoring, and technical guidance to less-experienced engineers and technical personnel.
• Collaborate with Product Management, Manufacturing, Quality, Supply Chain, and Commercial teams; participate in technical reviews and customer discussions and clearly communicate engineering findings, recommendations, status, risks, and tradeoffs.
• Apply CAD, simulation, statistical analysis, Design of Experiments (DOE), design failure mode and effects analysis (DFMEA), and structured problem-solving methods; promote sound engineering practices, technical documentation, and continuous improvement.
• Research emerging materials, cable architectures, and manufacturing technologies; identify improvements in cable density, flexibility, durability, environmental performance, material efficiency, process optimization, and cost; contribute invention disclosures, technical documentation, and patentable innovations and stay current with industry developments.

• Bachelor’s degree in Mechanical Engineering, Materials Science, Polymer Engineering, Chemical Engineering, Electrical Engineering, or a related technical discipline required; a master’s degree in Mechanical Engineering, Materials Science, Polymer Engineering, Chemical Engineering, or a related field is preferred.
• Typically, 7+ years of progressive experience in research and development, product engineering, or technology development within fiber-optic cable, telecommunications cable, or a closely related industry.
• Demonstrated experience in product design, development, testing, and qualification of cable products or related technologies, including application of engineering analysis, testing methodologies, and structured problem-solving techniques.
• Direct experience developing optical fiber cable products for outside plant, indoor, data center, or specialty applications; knowledge of high-fiber-count, high-density, compact, and specialty cable architectures is preferred.
• Strong technical understanding of cable construction, materials, optical and mechanical performance, and manufacturing processes; experience with polymer materials, mechanical design, environmental testing, and product reliability is preferred.
• Strong analytical problem-solving capability in engineering calculations, design analysis, root-cause investigations, technical decision-making, and evaluation of design alternatives.
• Demonstrated ability to independently manage complex technical assignments, coordinate project activities, prioritize competing demands, and achieve development milestones and engineering objectives.
• Experience collaborating with research, engineering, manufacturing, quality, product management, and commercial teams to support development and manufacturing implementation; ability to provide engineering guidance and mentor less-experienced colleagues.
• Strong organizational, written, verbal, presentation, and interpersonal skills; ability to communicate complex technical concepts, engineering findings, and recommendations clearly to technical and nontechnical stakeholders.
