Principal Structural Engineer

Structural analysis and design of lattice towers, wood pole (single, H-pole, trident) and steel pole structures

Tower/pole capacity studies for reconductoring, uprating, and line diversion schemes — assessing existing structures against revised loading

Review of PLS-CADD / PLS-POLE structural outputs and integration with the wider OHL design process

Structural input to feasibility studies and options assessments for new-build and refurbishment OHL schemes

Structural design of substation gantries, busbar support structures, plant support steelwork, and cable sealing end structures

Structural assessment of existing substation structures for plant replacement or uprating schemes

Coordination with electrical and civil disciplines on substation structural interfaces

Work directly alongside incumbent senior structural engineers during a structured handover period, to capture corporate knowledge, historic design precedent, and client-specific practice

Mentor and technically supervise Senior and Intermediate Structural Engineers within the team

Support recruitment, onboarding, and development of the wider structural engineering function

Champion structural engineering competency development across the OHL and substation design team

Ensure all structural design outputs comply with technical specifications, and client-specific standards

Author and review Designers Risk Assessments and structural design intent documentation under CDM 2015

Contribute to Temporary Works design and checking where structural expertise is required (tower propping, guying, temporary support systems)

Champion safe-by-design principles across all structural outputs

Degree in Structural, Civil, or Mechanical Engineering (or equivalent); Chartered Engineer (CEng) with IStructE, ICE, or equivalent professional body

Minimum 10 years structural engineering experience, with demonstrable experience of slender, guyed, or dynamically-loaded structures (lattice towers, masts, poles, or similar)

Strong working knowledge of structural steel design and structural analysis principles applicable to lattice and pole structures

Experience of foundation design principles for structures subject to overturning, uplift, and lateral loading

Demonstrated ability to lead technically complex structural assessments and provide design authority sign-off

Strong mentoring and team leadership capability, with experience developing less experienced engineers

Full UK driving licence

Direct experience of OHL lattice tower, wood pole, or steel pole structural design

Experience of PLS-CADD / PLS-POLE or equivalent OHL structural analysis software

Experience of substation structural design (gantries, plant support steelwork)

Experience of structural design in adjacent disciplines — telecoms masts, transmission towers, bridges, or other wind/dynamically-sensitive structures — where transferable to OHL

Experience of tower/pole capacity assessment for reconductoring or uprating schemes

Experience of SSE, SPEN, NGED, or National Grid framework delivery

CDM 2015 Principal Designer or Designer experience

Senior-level salary package commensurate with experience

Hybrid working arrangement — Horsham preferred, Glasgow or Warrington considered

A genuinely succession-critical role with direct handover from long-standing incumbent technical authorities

Structured mentoring into OHL-specific structural practice for candidates from adjacent disciplines

Chartership support and CPD funding

Company pension scheme

25 days annual leave plus bank holidays
