About this role

Standard Job Description  Join our team as a Staff AI Engineer focused on ontologies, knowledge graphs, and production AI systems. You will define how complex enterprise data becomes trusted knowledge that AI applications can understand and use. This role uses a forward-deployed engineering model. You will work directly with users, domain experts, data owners, and engineering teams. You will identify high-value problems and turn unclear needs into secure, reliable production capabilities. You will remain responsible from initial discovery through deployment and operation. As a Staff individual contributor, you will set technical direction across projects and teams. You will solve complex system problems, guide senior engineers, and create reusable platform capabilities. You will lead through technical judgment, delivery results, and trusted relationships. Formal personnel authority is not required. Responsibilities include: Lead technical discovery with users, domain experts, data owners, and engineering teams. Convert business needs into system requirements, architecture decisions, and delivery plans. Define architectures for AI agents, ontologies, knowledge graphs, data integrations, and user applications. Design semantic models that represent business concepts instead of physical source structures. Establish methods for ontology governance, source traceability, evaluation, version control, and human review. Build AI agent workflows that create, test, and improve trusted knowledge artifacts. Define evaluation methods for AI quality, semantic accuracy, query results, reliability, cost, and latency. Integrate databases, APIs, files, cloud platforms, and enterprise data systems. Lead development across services, APIs, background jobs, web applications, and graph query systems. Guide deployment through automated pipelines, containers, and cloud platforms. Resolve complex failures across AI models, applications, data sources, and infrastructure. Make tradeoffs among user value, security, quality, schedule, cost, and long-term support. Convert engagement-specific solutions into reusable platform capabilities. Review architecture and code for quality, security, supportability, and system fit. Mentor engineers and establish consistent engineering practices across teams. Present technical decisions, risks, and results to technical and business leaders. Influence technical direction across teams without formal authority. Basic Qualifications  A bachelor’s degree in a related STEM field and nine years of relevant experience. A master’s degree with seven years or a PhD with four years can satisfy the education and experience requirement. Experience developing production software in Python and architecting distributed or cloud-based systems. Experience architecting and deploying production AI, LLM, machine learning, or agent-based systems. Experience designing ontologies or knowledge graphs with RDF, OWL, and SPARQL. Experience leading technical work across teams and converting unclear user needs into deployed solutions. Desired Skills  Advanced experience with OWL, SHACL, R2RML, SPARQL, ontology reasoning, or semantic validation. Experience defining ontology governance, model reuse, version control, and review practices. Experience with graph databases or virtual knowledge graph systems. Experience with Amazon Neptune, Ontop, RDFLib, or comparable semantic platforms. Experience with AI agent frameworks and enterprise model platforms. Experience with AWS Bedrock, Azure OpenAI, or comparable model services. Experience evaluating LLM systems for accuracy, traceability, reliability, security, cost, and latency. Experience designing human review and approval controls for AI-generated artifacts. Experience with Django, asynchronous Python, Celery, PostgreSQL, Redis, or comparable technologies. Experience with React, TypeScript, or full-stack application development. Experience integrating SQL databases, REST APIs, OpenAPI
