You as a Sr. Specialist, Geospatial and Reality Capture will:

Survey Control and Georeferencing

  • Establish, validate, and document survey control for reality capture engagements using GNSS and total station methods.
  • Own coordinate system and datum management across projects, including transformations between project grids, MTM Zone 10, UTM Zone 17N, and NAD83 (CSRS).
  • Tie point cloud, photogrammetric, and GIS datasets to project control, and verify registration and georeferencing quality before delivery.
  • Prepare accuracy statements for delivered datasets, reporting results against independent checkpoints rather than software-internal residuals.

Field Capture Operations

  • Plan and execute drone capture, including flight planning, airspace review, ground control placement, and site-specific risk assessment.
  • Operate terrestrial laser scanning equipment (Leica RTC360 and BLK series) and mobile mapping systems on active construction sites.
  • Determine the appropriate capture method, density, and accuracy class for each engagement based on the intended use of the data.
  • Maintain equipment calibration, service records, and field readiness for all geospatial and capture hardware.
  • Apply and uphold EllisDon health and safety requirements on every site deployment, including capture-day method statements.

Geospatial Data and Deliverables

  • Build and maintain geodatabases, layer schemas, and spatial data standards for VDC Services engagements.
  • Produce GIS deliverables including site and corridor mapping, orthomosaics, topographic surfaces, volumetrics, and client-facing dashboards.
  • Deploy field data collection workflows using ArcGIS Field Maps or equivalent for site verification and asset capture.
  • Develop the BIM to GIS integration path, connecting models and point clouds to geospatial context for project and portfolio use.
  • Automate repetitive processing, translation, and quality assurance tasks using scripting and data integration tools.

Delivery and Client Support

  • Provide effort estimates and technical input to proposals, statements of work, and scope definition for geospatial engagements.
  • Act as the technical point of contact for geospatial scope on assigned engagements, communicating effectively with both project office staff and field superintendents.
  • Identify scope variations against the agreed statement of work and escalate change-order conditions to the engagement lead.
  • Document workflows, standards, and lessons learned so capability is retained by the team rather than held by an individual.
  • Support the technical development of VDC Specialists in survey control, drone operations, and geospatial fundamentals.

Is this the right role for you?

  • Diploma or degree in Geomatics, Geospatial Engineering Technology, Survey Technology, Civil Engineering Technology, or a related field. A GIS graduate certificate combined with field survey experience is an acceptable equivalent.
  • Three to six years of applied field geomatics or survey experience, including construction, infrastructure, utility, or municipal environments.
  • Demonstrated competence with GNSS RTK and network RTK, total station work, and the establishment and validation of control networks.
  • Working fluency in coordinate systems, datums, projections, and geoid models, with the ability to explain the effect of a transformation on measurement quality.
  • Transport Canada RPAS Pilot Certificate for Advanced Operations, with a current flight review and a documented flight log.
  • Proficiency in photogrammetric processing using Pix4D, Agisoft Metashape, DroneDeploy, Propeller, or equivalent, including ground control and checkpoint practice.
  • Experience operating terrestrial laser scanners and registering point clouds in Leica Cyclone, Register 360, or Autodesk ReCap.
  • Proficiency in ArcGIS Pro and ArcGIS Online, including geodatabase design, spatial analysis, and dashboard or web map publishing. QGIS experience is an acceptable foundation.
  • Working ability in AutoCAD Civil 3D, including surfaces, alignments, and point cloud to surface workflows.
  • Ability to produce clear technical documentation, including accuracy statements and quality assurance reports.
  • Strong organisation, attention to detail, and the ability to manage multiple concurrent engagements with minimal supervision.
  • Valid Ontario G driver's licence and access to an insured vehicle.
  • The salary range for this role is $88,000 to $102,000.
