Software Development Engineer 3 - Graph Engineering

About the Role Adobe is seeking a passionate engineer to join the Adobe Genuine Engineering team. This group protects Adobe's ecosystem from fraud, abuse, and misuse using intelligent systems worldwide. In this role, you will compose and develop our unified graph along with the detection systems running on it. You will merge multiple isolated fraud graphs into one scalable source that identifies non-genuine and abusive signals across hundreds of millions of users. You will manage the entire lifecycle: starting from raw behavioral and account data, progressing through large-scale graph modeling and ingestion using Databricks and Spark, applying Graph Data Science algorithms and graph ML, and delivering production-ready detection for enforcement. This role is for an engineer eager to manage graph systems entirely, covering schema, pipelines, community detection, and graph ML rather than using pre-built solutions. Key Responsibilities Build and evolve a unified graph schema that merges multiple fraud and account data sources into one consistent, rebuildable model. Develop and enhance large-scale graph ingestion and feature pipelines on Databricks and Spark, converting raw behavioral and account events into refined graph nodes, edges, and properties. Apply Graph Data Science (GDS) algorithms including community detection (WCC, Louvain, Label Propagation), centrality (PageRank), and node embeddings (FastRP, Node2Vec) to identify abuse rings, shared-entity clusters, and coordinated fraud. Develop graph machine learning models, including Graph Neural Networks (GNNs), to extract high-value risk signals from network structure, and incorporate them into downstream ML workflows. Translate prototypes into production graph systems that are scalable, reliable, and observable, and drive query and inference performance through modeling and serving-side optimization. Own operational health of the graph platform: incremental refresh, supernode handling, monitoring, and cost efficiency at scale. Contribute to MLOps and data-engineering practices: pipeline orchestration, versioning, CI/CD, automated retraining, and production monitoring. Collaborate cross-functionally with data science, product, and platform teams; experimentation rigor, and responsible AI. Stay current with advances in graph ML and network science and bring relevant innovations into Adobe's products. Minimum Qualifications Bachelor's degree or graduate degree or equivalent experience in Computer Science, Machine Learning, Data Science, or related field. 6+ years of professional experience building and deploying data or ML solutions at scale. Solid programming skills in Python, with practical experience developing extensive data pipelines on Databricks and Spark. Practical experience working with graph platforms such as Neo4j, Amazon Neptune, TigerGraph, or Memgraph, along with applying the Graph Data Science (GDS) library. Practical experience implementing GDS algorithms like PageRank, Louvain/Label Propagation for community detection, or Node Embeddings (FastRP, Node2Vec) to extract insights from network data. Comprehensive knowledge of the entire data and ML lifecycle, covering ingestion, feature engineering, deployment, and monitoring. Strong grasp of data modeling, query optimization, and production system integration. Preferred Qualifications Experience in applying Graph Neural Networks (GNNs) and connecting GDS pipelines with downstream machine learning workflows. Experience in fraud detection, anomaly detection, or behavioral modeling. Familiarity with Neo4j Aura or other managed graph databases, and with large-scale incremental graph refresh and supernode management.
