Cable Design Engineer

Job Purpose

To design and engineer cable constructions that meet customer requirements, applicable national/international standards, and manufacturability norms, while providing accurate technical documentation (BOM, drawings, specifications) that serves as the base for production, quality, and costing functions.

Key Responsibilities

• Interpret customer specifications, tender documents, and enquiries to determine cable construction requirements (voltage grade, current rating, application, environment).
• Design cable constructions including conductor sizing and stranding, insulation and sheathing type/thickness, screening, armoring, and overall cable layup.
• Select appropriate raw materials (conductor metal, insulation/sheathing compounds, armor materials) in line with technical and commercial feasibility.
• Perform electrical and mechanical calculations resistance, voltage drop, short-circuit rating, current carrying capacity, bending radius, etc.
• Ensure designs comply with relevant standards (IS, IEC, BS, UL, ASTM, customer-specific standards) and obtain/maintain product certifications.
• Prepare detailed Bill of Materials (BOM), construction data sheets, technical drawings, and specification sheets for new and existing products.
• Support new product development (NPD) — from concept design through prototype, type testing, and approval.
• Coordinate with production and quality teams to validate designs during trial runs and resolve manufacturability issues.
• Respond to technical queries from customers, sales team, and regulatory/certification bodies.
• Conduct or coordinate type tests and routine tests as required by standards and customer specifications.
• Maintain and update the technical database/library of standard designs, drawings, and specifications.
• Evaluate alternate/value-engineered designs (e.g., material substitution) in coordination with the costing team without compromising performance or compliance.
• Review and approve engineering change requests and maintain revision control of design documents.

Key Deliverables

• Bill of Materials (BOM) and construction/specification sheets for each cable design.
• Technical drawings and datasheets for customer approval and production reference.
• Type test reports and certification documentation.
• Design validation sign-off for new products and engineering changes.

Required Qualifications & Skills

• Bachelor's degree in Electrical / Electronics / Mechanical Engineering (or related field).
• Sound knowledge of cable construction principles and relevant standards (IS, IEC, BS, UL, ASTM).
• Proficiency in electrical calculations and design software/tools (CAD, cable design calculation tools, MS Excel).
• Understanding of raw materials used in cable manufacturing (conductors, polymers/compounds, armoring materials).
• Strong analytical, technical documentation, and problem-solving skills.
• Ability to coordinate cross-functionally with production, quality, costing, and sales teams.

Experience

2–8 years of experience in cable design/engineering within a cable manufacturing environment (experience range may vary by seniority level — Junior/Senior/Lead Design Engineer).

Key Interfaces

• Internal: Costing Team, Production, Quality Assurance, Sales & Marketing, R&D.
• External: Customers, Testing/Certification Agencies, Raw Material Suppliers.
