Senior Mechanical Design Engineer

Location: Greater Toronto Area (Toronto, ON), Canada

Role Overview

Our client seeks a highly skilled, rigorous Senior Mechanical Design Engineer to own and steward the 3D spatial model for their prototype facility in the Greater Toronto Area. Reporting to the technical leadership of the project, you will lead complex physical plant integration, automated 3D clash detection, space envelope allocation, and configuration control across all reactor and plant divisions. In this key role, you will oversee the production of manufacturing-ready drawing packages and manage critical reconciliation between as-designed CAD models and as-built metrology data during physical hardware fabrication and facility assembly.

Core Responsibilities

• 3D Plant Master Model Custodianship: Serve as a primary owner and custodian of the master 3D spatial assembly model for the stellarator device, cryostat, vacuum vessel, internal components, and balance-of-plant infrastructure.
• Clash Detection & Spatial Integration: Execute continuous automated 3D spatial clash detection, space envelope management, and physical layout integration across multidisciplinary systems (magnets, heating, diagnostics, cooling loops, and structural frames).
• Configuration & Change Control: Apply engineering change control protocols (ECRs/ECOs), managing baseline CAD revisions, design trade-offs, and technical risk registers throughout formal phase-gate reviews.
• Design Guidance & Drafting Standards: Guide mechanical design engineers, CAD specialists, and drafting technicians, enforcing standardized CAD modeling guidelines, layer conventions, and PLM database structures.
• Manufacturing Drawing Packages: Generate, verify, and approve detailed 2D/3D manufacturing drawing packages, geometric dimension and tolerance specifications, drawing standards, and Bills of Materials (BOM) for internal fabrication and external precision suppliers.
• As-Designed vs. As-Built Reconciliation: Lead physical reconciliation between as-designed CAD baselines and as-built laser scanning / 3D metrology data during component fabrication, factory acceptance testing, and facility site assembly to resolve dimensional variances.
  
  

Required Qualifications & Experience

• Education: Bachelor’s or Master’s Degree in Mechanical Engineering, Systems Engineering, Aerospace Engineering, or a related technical engineering discipline.
• Experience: 5+ years of progressive engineering experience managing complex 3D CAD models, plant spatial layouts, and mechanical integration for major industrial, nuclear, or aerospace facilities.
• CAD & PLM Software Mastery: Expert proficiency in enterprise 3D CAD and Product Lifecycle Management (PLM/PDM) software suites (e.g., Siemens NX, Teamcenter, CATIA, SolidWorks, or Windchill).
• Manufacturing & GD&T Expertise: Deep technical command of Geometric Dimensioning and Tolerancing, precision machining tolerances, welded pressure vessel standards, and manufacturing drawing approval workflows.
• Metrology & Configuration Skills: Proven track record in configuration management (ECO/ECR), spatial envelope control, and integrating 3D laser scan / CMM metrology data for as-built CAD reconciliation.
