About the role

Lead Mariana Minerals' piping design group and own the 3D model development, design workflows, and engineering standards for refining and minerals processing facilities.

Responsibilities

  • Build and lead Mariana's piping design group. Hire, develop, and directly manage piping designers and stress engineers
  • Manage the blended delivery team. In-house, staff-augs, high-value engineering centers, and third-party engineering firm piping groups
  • Load-balance work across concurrent projects, hold the schedule for piping deliverables, and coach designers through the work
  • Attract non-conventional engineering talent to piping design and engineering positions to develop advanced automation solutions
  • Own 3D model development end to end in Plant 3D and Revit. Plot plan and equipment layout through routing, supports, and IFC isometrics
  • Own how the model is built: structure and breakdown, project setup, naming conventions, revision control, and change rights
  • Own the spec catalogs and component libraries inside the model, so piping specs are enforced by the model rather than caught in review
  • Run 30 / 60 / 90% model reviews and Navisworks clash detection across disciplines, and drive resolution to closure
  • Define the model, drawing, and file format requirements EPCs and vendors deliver against, and integrate their content into Mariana's environment
  • Keep the model the single source of truth for quantities. Isometrics, BOMs, and take-offs generated from the model, not maintained beside it
  • Evaluate and implement state of the art agentic engineering and automation softwares
  • Develop and implement the piping design workflow itself. The path from P&ID to IFC, what gets checked at each gate, and who signs it
  • Build the standards behind it: piping design criteria, layout and access standards, drafting standards, iso and drawing templates, and support detail libraries
  • Establish squad check and design checking practice, with disciplined comment resolution, revision control, and IFR / IFA / IFC issue
  • Automate the repetitive work with our software team. Model-to-stress data exchange, spec-driven checks, quantity reporting, and QC scripting
  • Own the pipe stress program. Set the criteria, decide which lines are critical, and approve every package before it drives a support or a nozzle
  • Direct dynamic analyses. Slug flow, water hammer, relief valve transients, and vibration
  • Own piping material specifications, valve specs, and engineering standards, including material selection for hydromet, pyromet, and reagent services
  • Design and specify pipe supports, guides, anchors, expansion joints, and specialty components, and own the support detail standards
  • Ensure all piping systems comply with ASME B31.3, and B31.1 where applicable
  • Drive piping procurement and support construction and commissioning. Bulk material strategy, long-lead valves and specialty items, field RFIs, redlines, and as-built model closeout

Qualifications

  • 10+ years in piping design and engineering, delivered in an EPC, EPCM, or owner capital projects environment
  • Direct experience managing a piping design department or group
  • Demonstrated ownership of 3D model development on a capital project, concept through IFC, including multidiscipline reviews and Navisworks clash detection
  • Track record building piping design workflows and standards
  • Strong pipe stress background in Caesar II
  • Depth in ASME B31.3, including allowable load definition and nozzle load evaluation
  • Experience developing piping material and valve specifications and pipe support design criteria
  • Bachelor's degree in Mechanical Engineering or a related field
