Principal Applied Scientist

The Opportunity In SDC (Search, Discovery, and Content AI), we power semantic search, recommendations, and agentic experiences across Adobe’s creative ecosystem. A core priority is knowledge-grounded AI — integrating knowledge graphs, multimodal embeddings, LLMs, and ranking systems to deeply understand intent and creative content. We’re hiring a Principal Scientist to define how structured knowledge and foundation models work together at scale. You will architect next-generation graph-driven search, hybrid retrieval, and grounded generative systems that power real products used by millions. This is a deeply technical, high-ownership role! What You’ll Do You will build and evolve large-scale knowledge-grounded systems that connect queries, entities, concepts, and multimodal signals into coherent semantic architectures. Your work will span: Hybrid neural-symbolic retrieval and ranking Structured intent modeling and entity grounding Multimodal representations aligned with knowledge graphs Graph-grounded RAG and agentic systems You will also raise the scientific and architectural bar by: Defining evaluation frameworks for intent accuracy, entity grounding fidelity, graph coverage, and semantic relevance Establishing modeling and experimentation standards across teams Driving principled system building rooted in measurable impact Mentoring senior scientists and crafting cross-org technical direction Expect ambiguous problems, deep technical challenges, and visible product impact! Scope & Impact At the P60 level, you will build semantic architecture across multiple products and set the strategic direction for knowledge grounded AI. You will architect how our knowledge-graphs and foundation models evolve in tandem. You will be a recognized authority in knowledge-centric AI systems. Basic Qualifications PhD or equivalent experience (preferred) or MS in Computer Science, AI, ML, or related field 10+ years building and deploying large-scale AI/ML systems Deep expertise in knowledge graphs, information retrieval, NLP/intent modeling, multimodal learning, or LLM/RAG systems Proven track record delivering production-grade semantic platforms Preferred Qualifications Experience designing ontologies or evolving domain taxonomies Familiarity with graph embeddings, GNNs, or hybrid graph–LLM architectures Experience with entity linking, semantic parsing, or large-scale indexing systems History of cross-organizational technical influence What Sets You Apart You think in systems, not isolated models. You hold a high bar for rigor, clarity, and measurable impact. You influence through technical depth and sound judgment. You care about correctness — and building things that last!
