This is a great job for someone who is an experienced data architect who enjoys combining big‑picture thinking with hands‑on design. You’ll be comfortable simplifying complex operational data landscapes, modernising legacy data and integration patterns, and working closely with engineers and enterprise architects. You’ll thrive in a federated environment, influencing change through collaboration while delivering practical, high‑value improvements.
A bit about the job:
The Operational Data Architect designs and governs the architecture that underpins Aviva’s operational data flows and platforms. The role ensures operational data is accurate, trusted, secure, and efficiently delivered across systems, markets, and business functions. You’ll define and evolve target architectures for Operational Data Stores and operational data platforms, supporting key programmes such as Data Case for Change and Data Readiness for AI. Working closely with architecture, data governance, and engineering teams, you’ll balance short‑term delivery with long‑term strategic direction.
Skills and experience we’re looking for:
- Operational Data Architecture Expertise - Expert ability to design, govern, and optimise operational data — including transactional data modelling, operational data lineage, data quality controls, and end‑to‑end operational data flow patterns.
- Operational Data Store (ODS) Architecture & Engineering - Deep expertise in designing and governing Operational Data Stores (ODS), including structuring near‑real‑time data ingestion, ensuring performant storage patterns, decoupling consumption from source systems, enabling operational decisioning, and supporting downstream platforms such as AI, underwriting, and claims.
- Master & Reference Data Platform Architecture - Strong experience architecting and governing MDM and reference data platforms—covering domain mastering, matching/merging rules, golden‑record creation, publish/subscribe distribution, metadata‑driven governance, and integration of MDM with operational systems.
- OLTP & NoSQL Database Expertise - Hands‑on expertise with both OLTP relational databases (e.g., PostgreSQL, SQL Server, Oracle) and NoSQL datastores (e.g., DynamoDB, MongoDB, Cassandra). This includes schema design for transactional workloads, ACID properties, indexing, query optimisation, and high‑volume performance tuning, combined with NoSQL skills such as flexible schema modelling, partitioning, replication strategies, and scaling distributed data systems.
- Designing Performant, Resilient Operational Data Flows - Capability to architect scalable, resilient, compliant data‑flow and storage architectures that minimise duplication and ensure operational systems reliably serve business‑critical functions.
What you’ll get for this role:
Our purpose - with you today, for a better tomorrow – is a promise we make to our colleagues too. And one of the ways we live up to that promise is by investing in you.
