Workflow Data Fabric (WDF) connects the ServiceNow AI Platform to enterprise data wherever it lives - querying it in place, streaming it in real time, and ingesting it at scale so workflows and AI agents act on trusted, current data. We are looking for a Senior Staff Software Engineer to be a senior technical leader across the WDF platform organization. You will set architecture direction across multiple scrum teams, stay hands-on in the code, and own the hardest performance, scalability, and reliability problems across our data-access and data-movement products. Zero Copy Connectors and Remote Process Sync are the anchor areas for this role, with cross-team technical leadership spanning Data Fabric, Trino-based connectors, Stream Connect, ETL/Import Sets, Analytics Ingestion, and data quality.What You'll DoOwn end-to-end architecture for Zero Copy Connectors: the federated query path from the ServiceNow platform through a Trino-based query engine to external warehouses and lakehouses (e.g., Snowflake, Databricks, BigQuery, Redshift, Oracle, Iceberg), including pushdown, connection pooling, caching, authentication, and connector-framework extensibility as the connector portfolio scales.Own the technical direction of Remote Process Sync, our instance-to-instance process synchronization framework, driving throughput, parallel processing, ordering guarantees, resiliency, and supportability for high-volume customer and product integrations.Drive the architecture of Private Connectivity (Reverse Tunnel), which gives the platform secure, outbound-initiated access to customer data sources behind firewalls. The work covers mTLS tunneling, SNI-based routing, stream multiplexing, and the scale, resiliency, and security needed for enterprise and regulated customers.Provide cross-team technical leadership across the WDF portfolio – Data Fabric tables, Trino data connectors, Stream Connect (Kafka), ETL and Import Sets, analytics ingestion pipelines, and native data quality – ensuring coherent designs, shared frameworks, and consistent security and governance patterns. Lead architecture and design reviews; write and approve technical specifications; make and document build-vs-buy, protocol, and platform trade-offs with long-term maintainability in mind.Write production code in critical paths, prototype new approaches, and review code across teams to raise the engineering bar.Define and drive performance and scalability strategy: benchmarks, capacity models, and end-to-end performance validation for query, sync, streaming, and ingestion workloads before release.Serve as the senior technical escalation point for complex production and customer issues; drive root-cause analysis and turn recurring issues into durable platform fixes, observability, and runbooks. Partner with Product Management, Engineering Managers, Quality Engineering, Support, and adjacent platform teams (query engine, security, cloud infrastructure) to shape roadmaps, sequence technical investments, and de-risk delivery commitments.Mentor and grow senior and staff engineers; build technical depth and knowledge continuity so that critical areas are never dependent on a single person.
