About the Opportunity
Amentum offers an exciting opportunity to join our growing team of IT professionals to work on a range of projects for our diverse client portfolio that covers Critical National Infrastructure, National Security, Defence, and Nuclear market sectors. Our team is growing and we are looking for proactive and collaborative professionals at all levels to provide a range of services to our clients.
With deep technical, commercial, and strategic expertise, we develop solutions that address our client’s critical challenges supporting digitalisation and security. We are looking for a Data Architect with strong experience across Enterprise Data Architecture and/or Solution Data Architecture to support a UK MOD programme delivering Defence-wide data and integration capabilities. Operating across the CADMID lifecycle, you will help define and implement enterprise data principles, standards, and architectures, while also contributing to hands‑on data modelling, integration design, and governance.
Key Responsibilities
* Define and maintain enterprise data architecture, including principles, policies, standards, and reference models aligned with JSP 453 and Defence-wide integration frameworks.
* Develop architecture artefacts including conceptual, logical, and physical data models, data flows, and architecture blueprints.
* Translate business and operational needs into data architecture designs, ensuring alignment between enterprise strategy and system‑level implementation.
* Design data integration patterns and approaches (e.g. APIs, data pipelines, event‑driven architectures) to enable interoperability across Defence systems.
* Establish and support data governance frameworks, including data quality, metadata, lineage, and master data management practices.
* Contribute to AI/data governance principles, emerging technology assessments, and horizon scanning activities.
* Support the development of reusable patterns, guidance, and communities of practice to uplift data architecture capability across Defence.
Requirements
* Degree qualified in Data, Computer Science, Engineering, or related discipline (or equivalent experience).
* Strong analytical and problem‑solving skills, with the ability to define solutions to complex challenges.
* Excellent communication and stakeholder engagement skills, with the ability to influence at all levels.
* Ability to produce high‑quality technical documentation for both technical and non‑technical audiences.
* Ability to lead, mentor, and collaborate within high‑performing teams.
Experience
* 5+ years proven experience as a Data Architect within UK Defence or Critical National Infrastructure environments.
* Experience working across enterprise architecture and/or solution data architecture layers, bridging strategic and technical domains.
* Experience delivering across full system lifecycles (e.g. CADMID), including concept, design, and in‑service improvement phases.
* Experience defining and implementing data strategies, governance frameworks, and standards, including understanding of data governance disciplines (data quality, metadata management, lineage, cataloguing).
* Strong expertise in data modelling (conceptual, logical, physical) and data architecture design, data integration approaches (ETL/ELT pipelines, APIs, streaming, event‑driven architectures), and database technologies (relational, NoSQL, cloud‑native data platforms) and data storage architectures.
Standards & Frameworks
* Strong understanding of MOD data and integration standards, including JSP 453 – Defence Information Architecture.
* Familiarity with enterprise architecture frameworks (e.g. TOGAF, MODAF, UAF).
* Knowledge of data governance and security standards (e.g. NIST, ISO/IEC 27001).
