Enterprise Architect

Program Enterprise Architect – Platforms & Cyber Federal Government | Multi-Year Transformation Program | Canberra Based

A major Australian Government program is seeking a business-focused, results-driven Program Enterprise Architect with deep expertise across platforms, cyber security, and secure development environments. This role sits at the heart of a large, multi-stream modernisation initiative and provides end-to-end architectural leadership across technology, cyber, infrastructure, and application uplift activities.

You will join a central Enterprise Architecture function and play a pivotal role in shaping the target-state architecture, driving secure-by-design practices, and ensuring program delivery aligns with the whole-of-government standards, strategic roadmaps, and cybersecurity obligations.

This is a senior, influential position suited to an architect who thrives in complex environments, can lead across multiple delivery streams, and brings a strong blend of enterprise architecture, cyber uplift, and modern engineering practices.

Key Responsibilities: Program Architecture Leadership

• Lead architecture across multiple program streams, providing direction, integration, and assurance.
  
  
• Define and govern target state architectures aligned to strategic outcomes and enterprise standards.
  
  
• Manage cross-stream dependencies spanning ICT, cyber, infrastructure, and application remediation.
  
  
• Contribute architectural input into business cases, design artefacts, and delivery roadmaps.
  
  

Cyber Security Architecture

• Embed secure-by-design principles across identity, endpoint, network, and cloud domains.
  
  
• Ensure alignment to government security frameworks (e.g., Essential Eight, PSPF, ISM).
  
  
• Partner with cyber teams to uplift threat detection, prevention, and response capabilities.
  
  
• Provide authoritative guidance on risks, vulnerabilities, and mitigation strategies.
  
  

Developer Workstation Uplift (Key Accountability)

• Lead the uplift of secure developer environments across the program.
  
  
• Define and implement standardised, managed developer workstations (e.g., Intune-managed endpoints, approved toolchains).
  
  
• Drive secure software development practices, toolchain governance, and packaging/deployment models.
  
  
• Ensure developer platforms meet modern security, usability, and compliance expectations.
  
  

Architecture Governance & Assurance

• Represent architecture in governance forums, ensuring compliance and endorsement of designs.
  
  
• Conduct and oversee design reviews, solution assurance, and risk assessments.
  
  
• Ensure adherence to enterprise patterns, standards, and reference architectures.
  
  

About the Program: This multi-year federal initiative is delivering a major uplift of technology platforms, cybersecurity maturity, infrastructure, and legacy systems. The program is addressing long-standing technical debt, modernising core environments, and embedding secure by design practices across the organisation. Strong governance, executive sponsorship and sustained investment underpin the program’s success.

About You: You will bring:

• Extensive experience as an Enterprise Architect or Program Architect within large, complex transformation programs.
  
  
• Deep expertise across cyber security architecture (endpoint, identity, network, cloud).
  
  
• Strong understanding of DevSecOps, secure development environments, and developer tooling.
  
  
• Experience with endpoint management (e.g., Intune), device hardening, and secure workstation design.
  
  
• Proven ability to lead architecture across multi-stream programs with strong governance and assurance practices.
  
  
• Experience delivering technical debt reduction, modernisation, and platform uplift initiatives.
  
  
• Excellent communication skills and the ability to influence senior stakeholders.
  
  

Location & Clearance

• Canberra based
  
  
• Ability to obtain and maintain a baseline or NV1 clearance (existing clearance highly regarded)
  
  

Why This Role Matters This is a rare opportunity to shape the architecture of a major federal program with significant scope, visibility, and long-term impact. You will influence strategic technology direction, uplift cyber maturity, and modernise the environments that underpin critical national services.
