Senior Information Retrieval Engineer AIML Brand Concierge

Job description

Our Company

Changing the world through digital experiences is what Adobe’s all about. We give everyone-from emerging artists to global brands-everything they need to design and deliver exceptional digital experiences! We’re passionate about empowering people to create beautiful and powerful images, videos, and apps, and transform how companies interact with customers across every screen.

We’re on a mission to hire the very best and are committed to creating exceptional employee experiences where everyone is respected and has access to equal opportunity. We realize that new ideas can come from everywhere in the organization, and we know the next big idea could be yours!

The Opportunity

We are seeking a highly skilled Information Retrieval Engineer to lead the development and optimization of retrieval systems that power context-aware large language models (LLMs). This role focuses on building robust Retrieval-Augmented Generation (RAG) pipelines to ensure AI agents and applications have access to the most relevant, timely, and high-quality information.

You’ll work at the intersection of data engineering, machine learning, and knowledge management—enabling better reasoning, accuracy, and performance for enterprise-grade AI systems.

What you'll Do

RAG System Design

Architect and deploy scalable retrieval pipelines using vector databases (e.g., FAISS, Weaviate, Pinecone, Qdrant)

Implement semantic search infrastructure and hybrid retrieval systems (semantic + keyword)

Data Processing & Ingestion

Build ingestion pipelines for both structured and unstructured data sources

Implement document chunking strategies, embedding generation (e.g., OpenAI, Cohere, HuggingFace), and metadata tagging

Retrieval Optimization

Fine-tune relevance scoring, reranking algorithms, and query understanding mechanisms

Develop techniques to improve precision/recall for specific business domains or user tasks

Knowledge Enhancement

Create and maintain knowledge graphs to support context linking and disambiguation

Manage data freshness and version control to ensure consistency and reliability of retrieved content

Reasoning Support

Design and iterate on context window strategies that improve LLM reasoning (e.g., adaptive injection, task-based retrieval)

Collaborate with prompt engineers and model developers to align retrieval outputs with downstream model behavior

Performance Monitoring

Track key retrieval metrics such as accuracy, latency, and fallback rate

Implement caching, prefetching, and deduplication strategies to optimize system responsiveness

What you need to succeed

4+ years in data engineering, ML infrastructure, or information retrieval

Experience building and deploying RAG pipelines or semantic search systems

Strong Python skills and familiarity with retrieval libraries (e.g., Haystack, LangChain, Elasticsearch, Milvus)

Proficiency with embedding models, vector similarity search, and document indexing

Familiarity with cloud platforms and MLOps tooling (e.g., Airflow, dbt, Docker)

Preferred Qualifications

Knowledge of graph databases (e.g., Neo4j, TigerGraph) or knowledge graph design

Experience optimizing retrieval for LLMs (e.g., OpenAI, Anthropic, Mistral)

Background in IR/NLP, Search Engineering, or Cognitive Computing

Degree in Computer Science, Information Systems, or a related field
