• Curate canonical datasets: fiber routes/ducts, splice points, PoPs, customer sites, serviceability polygons, right‑of‑way constraints.
• Develop and maintain Python ETL/ELT pipelines (ArcPy/GeoPandas/Shapely/Fiona), data validation, schema mapping, and scheduled jobs.
• Implement and tune costing models (capex/opex parameters, trenching, aerial, wayleave, lease pricing), ensuring versioned models and audit trails.
• Integrate with OSS Inventory (resource/service models), CRM/Quotation, Order Management, and Document Management systems via REST/GraphQL/ETL.
• Enforce RBAC for map services and data access; secure credentials and API tokens; maintain audit logs.

Experience & Skills Requirements:

Must have:

• ArcGIS (Enterprise/Server/Pro): services publishing, geoprocessing, network analyst, data management, caching, security.
• Python: ArcPy, GeoPandas, Shapely, Fiona; building robust ETL/ELT pipelines; unit testing and packaging.
• Spatial databases: PostGIS / SQL Server / Oracle Spatial; query tuning, indexing, topology rules.
• Telecom OSS domain: Plan & Build, fiber design, serviceability; basics of Inventory models (resources/services, sites/PoPs, ducts/cables).
• Costing models: capex/opex drivers, labor/materials, route constraints; ability to version and audit.
• Integration patterns: REST/GraphQL, file‑based exchange, message queues; idempotency, retries, error handling.
• ITIL L2/L3: incident lifecycle, RCA authoring, problem records, change governance/CAB participation.
