About the Role
As an AI Architect, you will be the technical authority for the AI systems that power Protégé within PatentSight+. You will work across the full stack, from the agentic layer down, ensuring every layer is coherent, scalable, secure, and aligned with RELX Responsible AI standards. This is a senior individual-contributor role with broad influence, partnering closely with Engineering Leads, Product Managers, Data Scientists, and data teams within LNIP.
Responsibilities
- Define and own the AI architecture vision for Protégé in PatentSight+, ensuring technical decisions are coherent, future-proof, and aligned with product strategy.
- Evaluate and recommend AI technologies, modelling approaches, and platform components.
- Stay up to date with advances in agentic AI and domain-specific AI research, translating emerging capabilities into practical architectural recommendations.
- Author and maintain Architecture Decision Records (ADRs) and system design documentation.
- Architect the agentic reasoning systems that enable Protégé to decompose complex patent questions, plan multi-step analyses, and compose insights from multiple data sources.
- Design retrieval and search architectures that deliver accurate, low-latency patent intelligence across both structured analytics and unstructured text corpora.
- Define patterns for AI-driven enrichment and classification of patent data at scale, ensuring results are dependable, auditable, and consistent with established IP metrics.
- Establish prompt engineering standards, evaluation harnesses, and quality frameworks to govern LLM behaviour and maintain output accuracy in production.
- Partner with Product Management to assess technical feasibility and shape the AI roadmap, translating product goals into deliverable system designs.
- Collaborate with Security and Platform teams to ensure AI systems meet enterprise requirements for access control, data privacy, and regulatory compliance.
- Ensure all AI systems comply with RELX Responsible AI Principles.
- Lead AI risk assessment activities, contributing to compliance with applicable regulatory frameworks.
- Communicate complex architectural decisions clearly to senior leadership, engineering teams, and non-technical stakeholders.
Requirements
- Strong professional software engineering expertise, with experience in a dedicated AI/ML architecture, principal engineer, or distinguished engineer role.
- Proven track record delivering production LLM-based systems, including RAG pipelines, agentic/tool-use frameworks, and multi-step reasoning workflows.
- Strong proficiency in Python for AI service development.
- Working knowledge of C# or equivalent compiled language for enterprise microservice integration.
- Hands-on experience with vector databases and semantic search pipeline design.
- Experience with Model Context Protocol (MCP).
- Experience with large-scale data platforms such as Databricks and search engines such as Elasticsearch, in an analytical or AI feature engineering context.
- Demonstrated ability to design enterprise-grade AI systems with strong non-functional requirements: security, privacy, reliability, cost governance, and observability.
- Experience communicating complex architectural decisions through written documents, diagrams, and presentations to diverse audiences.
- Background in the intellectual property, legal technology, or scientific information domain; familiarity with patent data structures and classification systems.
- Knowledge of Responsible AI Principles.
- Experience designing event-driven, cloud-native architectures using Kafka (or equivalent streaming platforms), including topic design, schema governance, and consumer patterns.
