Senior R&D Engineer-Cable

Carrollton, GA- Onsite

Office: Work is primarily performed in a standard office environment utilizing typical office equipment and technology.

Job Summary

The Senior R&D Engineer – Cable is responsible for the research, design, development, testing, and optimization of fiber-optic cable products and technologies. This position provides advanced technical expertise in cable design, materials, optical and mechanical performance, and manufacturing processes to support new product development, innovation, and continuous improvement.

Working collaboratively with R&D, Product Management, Manufacturing, Process Engineering, Quality, Supply Chain, Commercial, and other cross-functional teams, the Senior R&D Engineer independently leads complex engineering assignments from concept and feasibility through design verification, qualification, manufacturing scale-up, and implementation. The role translates customer, industry, and business requirements into innovative, reliable, manufacturable, and cost-effective cable solutions.

This is a senior technical individual-contributor role requiring specialized knowledge of fiber-optic cable technologies, strong analytical and problem-solving skills, and sound engineering judgment. The engineer provides technical guidance and mentoring to less-experienced colleagues and contributes to the Company’s product development objectives and technological capabilities.

Major Duties and Responsibilities

Design, develop, and optimize fiber-optic cable products, components, materials, and technologies for telecommunications and other applicable markets; independently lead complex engineering assignments from concept through qualification and production implementation.
Translate customer, market, reliability, cost, and manufacturing requirements into engineering designs, product specifications, test plans, qualification requirements, and technical development plans; evaluate design alternatives and recommend balanced technical solutions.
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.

Job Qualifications

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.
Business acumen and an innovation and continuous improvement mindset, including understanding of product cost, manufacturability, customer requirements, and the commercial implications of engineering decisions; proficiency with Microsoft Office applications required.
Additional Requirements:
Familiarity with cable manufacturing technologies, including extrusion, stranding, jacketing, buffering, and related processes, and with applicable ICEA, Telcordia, IEC, and customer-specific product standards is preferred.
