Sydney, New South Wales, Australia Robert Walters Full time $125,000 - $175,000 per year
What you'll do:
  • Develop and maintain an enterprise architecture that supports organisational objectives and technology strategy while translating business dependencies into actionable architectures.
  • Lead architectural planning with a focus on cost optimisation by evaluating options based on capital versus operational expenditure impacts, especially in cloud platforms and operational technology convergence.
  • Establish and enforce comprehensive architecture governance frameworks by chairing review boards and defining principles, standards, and guardrails across all domains including cloud infrastructure and data.
  • Ensure project delivery teams adhere to approved architectural patterns by enforcing governance through solution design authorities within value streams.
  • Embed cybersecurity, resilience, and regulatory compliance into all aspects of architecture design-particularly for business-critical IT/OT systems-to safeguard operations.
  • Provide architectural leadership for digital transformation initiatives such as cloud migrations, advanced analytics deployments, IoT integrations, and automation projects.
  • Partner with infrastructure and data teams to ensure scalable, secure, and cost-optimised architectures for cloud-native platforms like AWS or Azure.
  • Facilitate architecture reviews and investment decisions by providing clear insights into business value, risk exposure, and cost implications for portfolio planning.
  • Act as a trusted advisor to executives by bridging strategic intent with practical execution while building consensus among diverse stakeholders.
  • Mentor architects across multiple domains to uplift maturity levels within the practice while fostering a collaborative culture focused on continuous improvement.
What you bring:
  • Extensive experience (7+ years) in enterprise architecture within complex environments such as utilities, energy or infrastructure sectors where asset intensity is high.
  • Proven track record in solution architecture delivery coupled with technical leadership roles overseeing large-scale projects from inception through execution.
  • Deep understanding of IT/OT integration challenges including hands-on experience navigating the convergence between operational technologies and information systems.
  • Expertise in designing architectures for cloud-native platforms (AWS/Azure), modern data platforms, analytics solutions, and supporting digital transformation initiatives.
  • Demonstrated ability to establish comprehensive governance frameworks-chairing review boards-and enforcing standards across multiple domains including security compliance.
  • Strong financial acumen enabling you to assess architectural decisions based on capital expenditure (CapEx), operational expenditure (OpEx), risk management considerations, and long-term value creation.
  • Exceptional stakeholder engagement skills allowing you to translate complex technical concepts into accessible language for executive audiences while building consensus among diverse groups.
  • Relevant certifications such as TOGAF for enterprise architecture or AWS Certified Solutions Architect for cloud specialisation; additional credentials in cyber security or risk management are highly regarded.
  • Experience working within regulated industries (e.g., energy sector) where compliance requirements shape architectural decisions is highly desirable.
