Principal Information Architect - Metadata Thought Leadership

JPMorganChase; Greater London; On-site; GBP 120,000 - 180,000; Full time

Job summary

JPMorganChase seeks a Principal Information Architect to drive metadata and language architecture for AI-enabled platforms. You will develop metamodels, create metadata assets, and design domain-specific languages, while engaging with stakeholders to implement architecture standards across a large engineering environment.

You will collaborate with data offices, product teams, and engineers to ensure semantic consistency, provenance, and secure, auditable data flows across complex systems.

Qualifications

• Create logical and physical data models for technical and non-technical audiences.
• Use UML modeling tools to express models clearly.
• Apply metamodel concepts (UML/MOF) to govern modeling approaches.
• Work with controlled vocabularies and metadata standards for consistency.
• Produce and interpret mappings and lineage to explain data relationships.
• Translate models into languages and domain-specific languages with ASTs.
• Program in Java, JavaScript, Python, or C++ and build language tooling components.
• Collaborate with business and technical teams to translate and review requirements.
• Design metadata/language architectures supporting AI-enabled solutions.

Responsibilities

• Develop and maintain the metamodel to support business needs.
• Create and evolve metadata assets: vocabularies, mappings, lineage, and data content descriptions.
• Build and maintain mappings between metadata and software assets.
• Design and maintain DSLs representing metadata structures.
• Prototype tooling that captures, integrates, validates, and generates code from metadata.
• Engage stakeholders to communicate architecture vision and standards.
• Architect metadata foundations enabling AI capabilities across engineering workflows.
• Establish governance for metadata-driven patterns and AI-enabled platforms.

Job description

Job Description

Step into the role of a Principal Information Architect (Executive Director) at JPMorganChase and become a promoting force behind the development and adoption of cutting‑edge, cloud‑based technologies. Make metadata real, usable, and impactful in modern engineering. In this role, you'll sit at the intersection of Information Architecture and Software Engineering—building models, languages, and tooling that help teams move faster with clarity and control. You'll have room to grow your craft, deepen your technical breadth, and influence standards across a large, complex environment.

Job Responsibilities

• Develop and maintain the metamodel to support current and emerging business needs
• Create and evolve novel metadata assets, including controlled vocabulary, mapping, lineage, transformation, and data content descriptions
• Build and maintain mappings between metadata and software engineering assets
• Design and maintain domain‑specific languages that represent metadata, including their underlying structures
• Prototype and maintain tooling that captures, integrates, validates, transforms, generates code from, reports on, and presents metadata
• Engage with customers, the Chief Data Office, product owners, Information Architects, development teams, and other stakeholders to communicate the Information Architecture vision and standards, and support effective implementation
• Architect metadata and language foundations that enable AI solution capabilities, including semantic consistency, provenance/lineage, policy tagging, and interoperability across engineering workflows
• Establish reuse‑first, metadata‑driven engineering patterns and governance that support AI‑enabled platforms (e.g., traceability/auditability, resiliency, and security controls) through well‑defined models, DSLs, and tooling integrations

Required Qualifications, Capabilities, And Skills

• Create logical and physical data models and express them clearly for both technical and non-technical audiences
• Use UML modeling tools (for example, MagicDraw, PowerDesigner, or Eclipse‑based tooling)
• Apply metamodel concepts (for example, UML and MOF) to structure and govern modeling approaches
• Work with controlled vocabularies and metadata standards to drive consistency and reuse
• Produce and interpret mappings and lineage to explain how data is related, moved, and transformed
• Translate between what is in a model and its corresponding representation in programming and schema languages. Build or maintain domain‑specific languages, including their abstract syntax structures
• Program effectively in one or more languages such as Java, JavaScript, Python, or C++. Implement language tooling components such as parsers, interpreters, compilers, debuggers, or related frameworks
• Prototype solutions independently and navigate ambiguous design and functionality problems
• Collaborate with business and technical teams to understand, translate, review, and playback requirements
• Intimately understand the relationship between what is in a model and its corresponding representation in other programming and schema languages. Similarly, for domain specific languages and ASTs.
• Demonstrated experience designing metadata/language architecture that supports AI‑enabled solutions, including enforceable semantics, lineage/provenance, and integration into scalable platforms with resilience, security, and auditability requirements

Preferred Qualifications, Capabilities, And Skills

• Exposure to code generation patterns and the development or use of code generators. Familiarity with data management technologies such as relational or columnar databases, data integration (ETL), or API development
• Familiarity with data formats such as JSON, XML, Avro, or Google Protocol Buffers
• Comfort engaging with the algorithms and mathematics behind languages, tooling, and data processing
• Academic background paired with hands‑on implementation experience
• Interest in how strong Information Architecture and models enable modern software development and engineering discipline
• Awareness of how modeling and metadata practices support regulatory and control requirements

If you're someone who enjoys working across modeling, metadata, languages, and software engineering—and you like bringing clarity, standards, and practical tooling to complex environments, we'd like to hear from you.
