Start here. Grow here. Are you ready to lead a team of talented engineers and shape the future of energy infrastructure? In this crucial role, you will be a key member of our Transmission & Distribution Overhead Lines team dedicated to leading and engaging with our clients to deliver technically challenging OHL design projects. Your primary focus will be to provide project technical support for the delivery of our major transmission projects, encompassing overhead transmission lines up to 400kV – including National Grids Great Grid Upgrade. You'll support a dynamic engineering team throughout the project lifecycle, providing detailed drawings from feasibility to construction and as‑built stages, playing a key role in maintenance of CAD standards, ensuring quality, accuracy, and consistency across all OHL design outputs.
Responsibilities
* Produce detailed 2D and 3D CAD drawings for overhead line structures, route layouts, and associated components.
* Prepare wire clearance diagrams, including ground profiles, crossing assessments, statutory clearances, and conductor behaviour envelopes.
* Generate detailed insulator set drawings, including string configurations, hardware assemblies, phase spacing, and structure interface details for 132kV-400kV OHL systems.
* Support Design engineers in producing PLS-CADD Plan & Profile drawings.
* Produce construction drawings, General Arrangements (GAs), fabrication details, schematics, and as-built drawings.
* Integrate survey data, LiDAR/point clouds, GIS information, and PLS-CADD outputs into CAD deliverables.
* Develop and maintain drawing libraries, templates, and symbols for the OHL discipline.
* Ensure full adherence to NG/ET/SR_135 – Drawings Management Process for any work affecting National Grid transmission assets, including design revisions and approvals through ECM/IDMS systems.
* Prepare drawing packs, as well as support and maintain Site Drawing Index (SDI), Contract Drawing List (CDL) and the Development Document Register.
* Review existing site drawings and suitability to reuse, assist with review master drawings (ECM/IDMS) and verify records are up-to-date and non-conflicting ahead of projects starting.
* Ensure all modified or new drawings comply with NG/ET/SR_135 and NG/ET/SR_188 Design Management requirements, providing coordination support by taking part in drawing reviews and commissioning workshops.
* Provide excellent technical support to milestone projects; interpret engineering calculations to produce and validate accurate technical drawings using PLS-CADD outputs. Deliver engineering support in route optimisation, clash detection, access planning and constructability reviews.

* CAD experience within the power transmission, overhead line, utility, or civil/structural engineering sector preferred.
* Experience using AutoCAD, MicroStation, Bentley tools, or similar CAD platforms.
* Strong experience with PLS-CADD including plan/profile generation and 3D clearance analysis (optional).
* Experience producing drawings for 132kV, 275kV, and/or 400kV OHL projects highly desirable.
* Prior experience working under National Grid or DNO standards.
* Ability to work with Georeferenced point clouds, LiDAR, GIS data, and 3D terrain models.
* Understanding of OHL design principles, conductor sag/tension behaviour, and structure spotting highly desirable.
* Excellent attention to detail, accuracy, and consistency; strong communication/coordination skills.
* Quality driven and meticulous.
