• Develop and maintain design criteria, technical specifications, and engineering standards.

• Oversee production of models, calculations, reports, drawings, and technical deliverables to required quality standards (BIM/L2 or L3).

• Coordinate their requirements with structural, architectural, fire engineering, electrical, RAMS, and rail systems teams.

• Manage interfaces with the client, contractors, HS2 / Network Rail teams, utilities providers, and third-party stakeholders.

• Ensure their systems integrate with station operations, control systems, and emergency procedures.

• Lead design assurance activities including compliance with UK Building Regulations, fire strategy, railway standards (e.g., NR/L2, HS2 standards), and relevant British/European codes.

• Manage hazard identification, risk assessments and safety documentation in accordance with CDM.

• Support System Safety, EMC, RAMS, and HAZOP/HAZID processes.

• Develop design programmes, monitor progress, manage risk, and ensure design delivery to schedule and budget.

• Ensure as-built documentation and design changes are accurately captured.

• Chartered Engineer (CEng) with ICE, IMechE, CIBSE or equivalent.

• 10+ years of design experience in major rail, metro, or large-scale infrastructure projects.

• Deep knowledge of ventilation, HVAC, smoke control, and MEP systems for complex transport environments.

• Strong understanding of BIM, digital design workflows, and multidisciplinary coordination.

• Track record of leading teams in high-value, multi-stakeholder engineering projects.

• Excellent communication, documentation, and leadership skills.

• Experience with HS2, Crossrail, or major UK station design.
