Overhead Lines Technologist

The WSP Africa Power and Energy team is seeking a competent and responsible OHL Design Engineer to join the team. The role involves delivering detailed design packages for overhead powerlines, conducting OHL-related studies, and using PLS- Suite extensively. The ideal candidate should have experience for voltages ranging from 132kV to 765kV. The successful candidate will contribute to both local and international projects, ensuring compliance with local and international standards.

Technical Leadership

• Responsible for tower spotting and line profiling activities for OHL projects using PLS-Suite (e.g. PLSCADD and PLS Pole)
• Define optimum tower positions considering clearances, spans, conductor sags, terrain, and servitude constraints.
• Ensure alignment of spotting outputs with electrical, structural, and civil requirements.
• Drive compliance with Eskom guidelines, SANS 10280, BS EN 50341, and international OHL design standards.
• Lead and manage independently OHL projects ( local and international) - 132kV to 765kV
• Design Management
• Prepare and check line profiles, stringing charts, and plan-and-profile drawings.
• Manage inputs from survey data, LiDAR/DEM, and topographical models into PLS-CADD.
• Evaluate alternative line routes and tower configurations for cost, constructability, and environmental impact.
• Ensure spotting outputs are coordinated with foundation locations and access road planning.
• Full design packages (FEED, CONCEPTUAL, DETAILED and EXECUTION READY) - (132kV - 765kV)

Quality & Compliance

• Maintain accuracy of spotting and profiling models, ensuring correct application of clearance rules and safety codes.
• Conduct peer reviews and internal audits of PLS-CADD outputs.
• Champion continuous improvement of tower spotting standards, workflows, and digital datasets.

Project Delivery

• Provide tower spotting inputs for feasibility studies, detailed design, and construction planning.
• Support construction teams with staking sheets, tower schedules, and setting-out data.
• Resolve site issues related to terrain discrepancies, clearance adjustments, or route deviations.
• Contribute to BOQs, material take-offs, and project cost estimates.
• Assist junior engineers and designers in PLS-CADD modelling, tower spotting logic, and clearance verification.
• Build team capacity in LiDAR integration, terrain modelling, and advanced spotting methodologies.
• Review outputs from junior staff, providing technical coaching and QA feedback.

Client & Stakeholder Engagement

• Present spotting methodologies, clearance compliance, and route optimization studies to clients.
• Provide technical input for tender submissions, proposals, and client workshops.
• Act as the PLS-CADD subject matter expert in multidisciplinary design review sessions.
• Strong client relationships and team culture
• International Travel and local travel when required

Health and Safety

• Upholding standards for SHEQ performance and behaviour consistent with the company's health, safety, environmental and quality vision, and policies by influencing those around you.
• Contributing to the identification of SHEQ risks and driving processes to achieve Zero Harm.
• Embracing, displaying, and promoting the company values and ensuring a safe working environment is always maintained.

• Education: Bachelor's in Electrical/Mechanical/Structural Engineering.
• Professional Registration: Ideally hold Pr. Eng or Pr. Tech Eng registration or be registered as a candidate engineer
• Software Proficiency: Highly proficient in PLSCADD. including: PLS Pole and PLS Tower, AutoCAD, CDEGS will be advantageous.
• Experience: Minimum of 3 years' OHL experience
