Lead Data Architect (Investment Management) (Contract)

Data architecture and modelling

• →Design and develop the conceptual, logical and physical data models for investment data domains: security and reference data, positions and holdings, transactions, valuations and pricing, performance, benchmarks, risk, compliance, accounting and client reporting.

• →Define and govern golden-source, reference-data and master-data standards for instruments, parties, legal entities, accounts and portfolios, including identifier strategy, entity resolution, lifecycle states, schema versioning and change control.

• →Produce implementation-ready artefacts: DDL, transformation and mapping specifications, interface contracts and data quality rules.

• →Define the IBOR / ABOR data design and the reconciliation points between investment and accounting books of record, with end-to-end auditability.

• →Define source-to-target data flows and mappings centred on SimCorp Dimension, covering market and reference data vendors, custodians, counterparties, and downstream reporting and analytics.

Unstructured data and retrieval architecture

• →Develop the conceptual, logical and physical data models for unstructured investment-information domains, including sell-side and broker research, market commentary, news, internal analytics and knowledge assets.

• →Define the architecture and standards for document ingestion, processing and indexing, ensuring that source context, document structure and temporal attributes are preserved.

• →Define metadata, taxonomy and classification standards for unstructured content to support governance, discoverability and retrieval.

• →Define the architecture and technical standards for the vector database and embedding lifecycle, including embedding model selection, index design, evaluation and retrieval optimisation, and guide the AI Engineer’s implementation.

• →Define the entity and metadata mappings that link unstructured content to portfolio holdings and trades, enabling relevant research and news to be retrieved against current exposures.

• →Design hybrid retrieval orchestration spanning all three layers (vector similarity combined with keyword filtering and metadata ranking) to support near-real-time market surveillance.

Platform and integration

• →Define integration patterns and interface standards for batch, API, messaging and event-driven exchange across the investment-data ecosystem.

• →Shape the target data platform for analytics and reporting across on-premise RDBMS / data warehouse and cloud lakehouse, and guide the migration path between them.

• →Evaluate technology and vendor options, weighing performance, resiliency, security, cost and operational complexity.

• →Take part in platform upgrades, replatforming and data migration, owning data mapping, parallel runs, cutover, reconciliation and legacy decommissioning.

Governance, quality and control

• →Develop the data-governance framework and accountable ownership model covering metadata, business and technical lineage, data quality, retention, and access rights.

• →Ensure designs meet MAS technology standards and Whole of Government compliance requirements.

• →Define data classification and access controls for sensitive investment data, applied consistently across all three layers including unstructured research content.

• →Define source-data lineage and audit requirements for reconciliation outcomes and AI retrieval; work with the AI Engineer to ensure end-to-end traceability across data, retrieval, model and application logs.

Leadership and delivery

• →Serve as the design authority for investment-data architecture, lead data design reviews, and steer change proposals through the MAS Architecture Review Committee to validate alignment with Enterprise Architecture standards.

• →Partner with portfolio management, investment operations, risk, finance, compliance and vendor teams to translate business needs into data designs.

• →Work to a defined cadence with the Investment Operations & Data Domain Expert to validate the holdings model, reconciliation logic and document classification against confirmed user stories, and with the AI Engineer to assess data-layer readiness for agent retrieval.

• →Hold decision authority for investment-data architecture. Make cross-cutting architecture and technical trade-offs jointly with the AI Engineer, subject to validation by the Domain Expert that the proposed design meets operational needs.

• →Translate complex data concepts for senior business and technology stakeholders.

• →Ensure that the data architecture provides governed metadata, semantic definitions and access controls for analytics, machine learning and generative AI use cases.

Must have:

• Degree in Computer Science, Information Systems, Engineering or a related field, or equivalent experience.

• At least 10 years of relevant experience across data architecture, data modelling or senior data engineering, with substantial experience designing data solutions for investment management, asset management, institutional investment, capital markets or closely related financial-services domains.

• Deep knowledge of investment data domains including security/reference data, positions and holdings, transactions, valuations/pricing, performance, benchmarks and IBOR/ABOR. Experience designing and implementing reconciliations across IBOR, ABOR, custodians, market data providers and downstream reporting systems.

• Hands on experience with modern data platforms such as Snowflake, Databricks, Spark, Kafka, or cloud-native data services on AWS or Azure; containerised deployment (Docker, Kubernetes).

• Strong relational database design experience, preferably Oracle, including performance and high-availability considerations.

• Track record of delivering at least one large-scale data migration or platform replatforming programme in financial services.

• Working knowledge of data governance, lineage, metadata management and data quality frameworks.

• Strong hands-on experience in conceptual, logical and physical data modelling, including relational and dimensional modelling, and in producing implementation-ready data specifications.

• Hands-on experience with vector search and embedding-based retrieval — including vector index design, embedding model selection, and hybrid search combining vector similarity with keyword and metadata filtering.

• Strong written and verbal communication, including producing clear architecture documentation.

Preferred:

• Hands-on experience with front-to-back investment management platforms, including their data models and data management capabilities.

• Hands-on experience with document parsing and OCR for scanned and text-native PDFs, including layout and table extraction, and with semantic chunking strategies suited to long-form research documents.

• Experience with market and reference data vendors such as Bloomberg, Refinitiv (LSEG) or ICE, and with economic indicator providers such as Macrobond.

• Knowledge of private markets data, ESG data, or multi-asset portfolios.

• Familiarity with data mesh, data products and federated governance concepts.

• Experience designing data foundations for retrieval-augmented generation or similar AI retrieval patterns in a regulated environment.

• Programming experience in SQL, Python or Java.

Personal attributes:

• Balances architectural standards with pragmatic delivery.

• Comfortable owning design decisions and defending them with evidence.

• Builds trust with business users and engineers alike.

• Develops others and raises the team’s design quality.

• Comfortable designing under a human-in-the-loop operating principle, where every automated output must remain reviewable and auditable.
