Overview

A mining sector client is looking for a P&ID Designer with solid COMOS software experience to join their engineering team. You will develop and maintain Piping and Instrumentation Diagrams for mining, minerals processing and heavy industrial projects. This is a permanent full time role based in Johannesburg with site work in Pretoria. If you have 3 to 7 years of EPCM experience and enjoy working closely with process engineers on complex technical drawings, this could be a great fit for you.

About the role

Our client in the mining sector needs a P&ID Designer with proven COMOS software experience to become part of their Project Delivery Team. You will focus on developing and maintaining Piping and Instrumentation Diagrams using COMOS, and you will design, update and manage technical drawings and databases across mining, minerals processing and heavy industrial projects.

You will work closely with process engineers, designers and cross functional teams to make sure project deliverables integrate smoothly. The role also requires a willingness to work on site in Pretoria when needed.

Day to day you can expect to interpret process flow diagrams and engineering calculations, update P&IDs throughout the design lifecycle, and support multidisciplinary design coordination. You will also take part in design reviews and help resolve technical queries related to P&ID development.

  • Proven experience with COMOS software is essential
  • Proven experience with CAD tools such as AutoCAD, SolidWorks, MicroStation or similar
  • Strong understanding of engineering and design principles
  • Strong understanding of P&ID symbols, standards and drafting conventions
  • Ability to interpret process and instrumentation requirements
  • Excellent problem solving and communication skills
  • Ability to manage time effectively and work in a fast paced environment
  • Strong attention to detail and accuracy
  • Must be willing to work on site
  • Exposure to multidisciplinary design coordination
  • Familiarity with data centric engineering systems

Responsibilities

  • Develop and maintain P&IDs using COMOS according to project standards and specifications
  • Interpret process flow diagrams, engineering calculations and design criteria to produce accurate P&IDs
  • Update P&IDs throughout the design lifecycle, including changes from design reviews, HAZOPs and client feedback
  • Ensure consistency and integrity between P&IDs and related engineering deliverables
  • Design, update and manage technical drawings and databases
  • Work on engineering projects involving COMOS and CAD software
  • Collaborate with cross functional teams to ensure seamless integration of project deliverables

Success Guide

If you are applying for this P&ID Designer role, put your COMOS experience front and centre. This is the one skill the client has flagged as essential, so make sure your CV clearly shows which projects you used COMOS on and what you delivered. Also highlight any mining, minerals processing or heavy industrial exposure you have, because that is the environment you will be working in.

With 3 to 7 years of EPCM experience needed, this is a mid level position. Be ready to talk about how you handle design changes from HAZOPs and client feedback, and how you keep your P&IDs consistent with other engineering deliverables. Since the role involves site work in Pretoria, mention that you are willing to travel or work on site. A short cover note explaining why this mining project interests you can go a long way.
