Job Summary:

We are looking for a highly skilled and experienced individual to join our engineering team as a Senior Draughtsman specialising in Substation (Mechanical Engineer) for Fire Fighting Systems. This role presents a unique opportunity for a draughting professional with expertise in mechanical substation systems and fire safety infrastructure to produce technical drawings and documentation of the highest standards. The successful candidate will be an essential part of multidisciplinary teams, ensuring the coordinated delivery of substations and fire protection systems aligned with regulatory standards and client requirements.

Key Responsibilities – Substation Mechanical Draughting & Fire Fighting Systems Design

• Prepare accurate and detailed mechanical drawings, layouts, and schematics for substation fire fighting systems, including fire suppression, detection, and safety systems.
• Develop general arrangement drawings, isometrics, P&IDs (Piping and Instrumentation Diagrams), fabrication details, and installation layouts for mechanical fire protection infrastructure.
• Revise and update mechanical drawings throughout all stages of substation and fire fighting system projects, ensuring accuracy and alignment with evolving requirements.
• Work collaboratively with multidisciplinary engineering teams, project managers, and external contractors to ensure all documentation complies with project specifications, safety codes, and regulatory guidelines.
• Maintain organised drawing registers and version control for all mechanical system schematics and project documents.
• Conduct site visits for surveys, as-built verifications, or to resolve design and installation coordination issues as they arise.
• Contribute to continuous improvements and standardisation of mechanical draughting methods and fire protection system documentation within the department.
  
  

• Advanced proficiency in AutoCAD, Revit, or similar CAD software for mechanical design and 3D modelling.
• Strong attention to detail and commitment to producing high-quality, accurate and compliant technical drawings.
• Effective organisation skills, capable of managing multiple simultaneous projects and prioritising tasks to meet deadlines.
