The EL2 Domain (Data) Architect provides strategic architectural leadership across a defined business or technology domain. You will develop and maintain the domain architecture, target state and transition roadmap, ensuring technology investments and solutions align with organisational strategy, enterprise architecture principles and business priorities.

Working across programs, projects and multidisciplinary teams, you will provide authoritative architectural advice, guide solution design and ensure consistency and interoperability across the domain — identifying dependencies, opportunities for reuse and emerging architectural risks.

At EL2 the role operates with a high degree of autonomy and influence, advising senior executives and governance forums and leading the resolution of complex architectural issues that span multiple systems, programs and organisational boundaries.

Responsibilities

- Develop, maintain and communicate the architecture, target state and strategic roadmap for a defined domain.
- Provide authoritative architectural advice and technical leadership across programs, projects and initiatives.
- Ensure solution architectures and technology investments align with enterprise architecture, domain strategy and security requirements.




- Lead architectural analysis of complex problems and develop strategic options, recommendations and transition approaches.
- Establish and maintain domain-level architecture principles, patterns, standards and guardrails.
- Review and assure solution designs, identifying cross-domain dependencies, risks, gaps and opportunities.
- Work with enterprise, solution and security architects, data engineering leaders, business stakeholders and delivery teams.
- Influence investment and prioritisation decisions with transparent advice on architectural impacts, dependencies, risks and sequencing.
- Represent the domain at architecture and governance forums.
- Monitor emerging technologies and assess their impact on the domain.
- Lead the resolution of significant architectural issues and manage complex trade-offs between strategic direction, delivery priorities, risk, cost and technical constraints.
- Build architectural capability through leadership, guidance and mentoring.

Skills & experience

- 8+ years designing and delivering complex enterprise data initiatives and solutions, with at least 3 years at EL2 or equivalent principal architect level (or relevant industry experience).
- Demonstrated ability to translate organisational strategy,



business requirements and complex technology considerations into coherent domain architecture and strategic direction.
- Extensive experience developing and applying architecture principles, patterns, standards and governance across multiple programs, systems or delivery initiatives.
- Ability to analyse complex architectural issues, dependencies and trade-offs and provide authoritative, evidence-based recommendations to senior stakeholders and governance forums.
- Strong understanding of contemporary enterprise technology environments, data management practices, MDM, RDM, data modelling and data security.
- Demonstrated senior stakeholder leadership and communication skills, including the ability to influence executives, architects, technical specialists and delivery teams and achieve alignment across competing priorities.
