Job Description
Role Overview
This role is part of a broader enterprise initiative to establish a Data Context Layer (DCL) - a foundational capability designed to provide consistent, reusable, and scalable @context across enterprise data products.
The DCL is intended to address challenges related to data fragmentation, lack of shared semantics, and inconsistent interpretation of data across systems and products . It establishes a unified layer for representing @context, relationships, and meaning, enabling downstream products to operate with greater consistency, interoperability, and intelligence.
In addition, the DCL plays a critical role in enabling agentic AI capabilities across the enterprise by providing the structured @context and semantic grounding required for intelligent agents to operate reliably. This includes ensuring that agent-driven workflows and decisions are based on consistent, governed, and interpretable data @context , reducing risks associated with fragmentation, ambiguity, and lack of control.
Within this initiative, we are seeking a Lead Architect to define and guide the conceptual and technical architecture for an enterprise platform that enables teams to publish, discover, and consume standardized data @context through self-service . This role will shape the target architecture, integration patterns, and technical standards that support scalable, secure, and production-ready @context services across the enterprise.
The ideal candidate has deep experience in enterprise architecture, data platforms, semantic technologies, and AI-enabled systems. Familiarity with ontologies, OWL, metadata-driven architectures, agentic AI, prompt engineering, and @context engineering is required, as the platform must support both human and AI-driven consumers of @context.
Key Responsibilities
Define the target architecture for the enterprise data @context self-service platform.
Establish architectural standards and patterns for:
@context publishing
discovery
access control
versioning
validation
lineage and provenance
observability and monitoring
Partner with product, engineering, service design, security, and governance teams to ensure the platform is technically sound and aligned to enterprise needs.
Evaluate and recommend technologies and integration patterns including:
ontology and semantic modeling approaches
OWL/RDF-based systems
knowledge graphs
semantic layers
MCP, A2A, and Timbr-like technologies where applicable
Design architecture that supports both self-service user workflows and AI/agentic consumption patterns.
Ensure @context can move from development to production in a governed, scalable, and supportable way.
Define non-functional requirements including performance, resilience, security, compliance, and operational maintainability.
Review solution designs and implementation plans to ensure adherence to architectural standards.
Create reference architectures, patterns, and decision records to guide implementation teams.
Collaborate with platform teams to support long-term scalability, reuse, and interoperability across domains.
Help shape how the platform supports agentic AI workflows , including structured prompt @context, tool access, and reliable data grounding.
Minimum Required Qualifications
Bachelors degree
8+ years of experience in enterprise architecture, solution architecture, data architecture, or platform architecture.
Strong technical background in data platforms, metadata systems, semantic technologies, or AI infrastructure.
Familiarity with ontologies, OWL, RDF, knowledge graphs, and semantic layer concepts .
Experience designing platforms that support self-service, enterprise-scale reuse, and governed access.
Expertise in agentic AI, prompt engineering, and @context engineering concepts.
Experience defining and enforcing technical standards across multiple teams.
Strong ability to communicate architecture decisions to both technical and non-technical stakeholders.
Preferred Qualifications
Experience with MCP, A2A, Timbr, or similar @context-serving or semantic interoperability technologies.
Background in enterprise data governance, metadata management, or data catalog architectures.
Experience supporting AI-enabled platforms or agentic workflows.
Knowledge of production concerns such as observability, testing, CI/CD, identity and access management, and lifecycle management.
Experience creating reference architectures and reusable patterns for platform teams.
Familiarity with regulated or security-sensitive enterprise environments.
What Success Looks Like
Success in this role means:
the platform has a clear, scalable Conceptual/Technical architecture
@context is served consistently and securely across the enterprise
teams can build and integrate using reusable patterns
development-to-production flows are reliable and governed
the platform supports both enterprise applications and AI/agentic use cases
architectural decisions reduce duplication and increase long-term maintainability
