• Procon Consulting is seeking a Lead Indoor GIS / Digital Twin Developer (remote, US‑based) to plan, develop, integrate, and maintain indoor GIS “digital twin” solutions that connect BIM, ArcGIS Indoors, CMMS (e.g., Maximo), Survey123, cloud document repositories, ArcGIS‑oriented imagery, and other facilities data sources for operations and maintenance. • You will lead end‑to‑end delivery of indoor GIS / digital twin projects: scoping and planning work, coordinating with clients and partners, running Agile‑style sprints, and serving either as project manager or as technical lead reporting to a PM, depending on the engagement. • You will design and implement ArcGIS Indoors solutions (indoor geodatabases, facilities/floor layers, 2D/3D web maps and scenes) and build BIM‑to‑GIS workflows to convert validated Revit models (architectural, structural, MEP) and COBie asset data, prepared by BIM specialists, into indoor GIS, including georeferencing, level attribution, multipatch geometry, and points of interest. • Working closely with BIM specialists, you will consume and import vetted BIM models, COBie exports, and other curated asset data into GIS rather than performing primary BIM/COBie authoring or assessment yourself. • You will also import and integrate additional datasets such as historical drawings and legacy documentation in various formats (e.g., DWG, PDFs) as appropriate base or reference layers within the digital twin environment. • The role is responsible for implementing and enforcing data architectures and workflows that respect established “sources of truth” across BIM, GIS, CMMS, and document repositories, and for operating data reconciliation and visualization tools that depend on those validated inputs. • You will design, configure, and maintain integrations between indoor GIS and CMMS and related systems, using ETL/orchestration tools (such as FME or equivalent) and, where appropriate, direct API‑based integrations between ArcGIS and CMMS platforms. • A key focus is ArcGIS‑oriented imagery: designing workflows to ingest 360° construction and facility imagery (e.g., from OpenSpace or similar tools) into ArcGIS as oriented imagery datasets, using Python, APIs, and geoprocessing tools to expose imagery as services tied to floor plans and asset locations. • You will integrate these reality‑first imagery layers with Indoors maps/scenes so end‑users can navigate floorplans and launch context‑aware 360° views as part of the digital twin experience. • You will also lead GIS‑side data reconciliation and quality workflows (e.g., Experience‑Builder or similar apps) to help align BIM, GIS, and CMMS records based on already‑validated data, and develop reusable templates, reference geodatabases, and SOPs to scale solutions across portfolios. • In addition, you will support ongoing operations (model/data updates, performance tuning, user support) and contribute to proposals, estimates, and solution roadmaps for new and existing Procon clients. • This is a remote US‑based position with occasional travel to Procon HQ in Northern Virginia and to customer locations and conferences nationwide.
