We are building a capability-led engineering function focused on evaluating, designing, and evolving complex technology services at scale.
This role is suited to a senior engineer, architect, or principal-level practitioner who operates comfortably in ambiguity and brings strong technical judgement to guide service design, modernisation pathways, and engineering decision-making.
You will work across multiple systems and stakeholders to define what should be retained, modernised, or transitioned, supported by deep technical analysis, structured documentation, and evidence-based recommendations.
Key Responsibilities
* Provide independent engineering advice to shape service and architecture decisions
* Define technical scope, assumptions, and design options across complex environments
* Develop service designs, architecture views, and supporting artefacts
* Establish baseline models of current services vs infrastructure
* Assess feasibility, risks, constraints, and trade-offs across multiple options
* Shape modernisation and transition strategies for existing services
* Contribute to validation approaches, including testing and assurance planning
* Document dependencies, constraints, and engineering rationale to support governance and investment decisions
Skills & Experience
* Experience operating as a Principal Engineer, Senior Engineer, or Solution/Technical Architect
* Strong background in complex, enterprise-scale environments with multiple dependencies
* Ability to influence through technical expertise and structured advice, not authority
* Deep experience in:
o Service design and architecture
o Systems engineering and integration
o Large-scale infrastructure and platform environments
* Strong capability in analysis, modelling, and technical documentation
* Experience working within structured governance, assurance, and compliance frameworks
* Comfortable working under broad direction with accountability for complex outputs
Requirements
* Must hold active NV1 clearance
* Based in Canberra
Why This Role
This is a decision-shaping role. You will operate at the intersection of engineering, architecture, and strategy, influencing how complex services evolve through technical insight, structured analysis, and defensible recommendations.
