Amazon Web Services; Sydney; On-site; AUD 180,000 - 240,000; Full time

Job summary

Amazon Web Services is seeking a Pr. Delivery Consultant to lead the Application Modernisation workstream within AWS Professional Services. The role focuses on decomposing a decades-old Oracle monolith into domain APIs and delivering production-grade web APIs that balance future architecture with pragmatic delivery risk.

You will mentor teams, define domain boundaries, and advise senior stakeholders on architecture decisions that optimise change, risk, and business impact across multiple units.

Qualifications

• Experience managing and delivering large-scale enterprise IT projects.
• Experience with software development life cycle (SDLC) and agile/iterative methodologies.
• Experience implementing AWS services in a variety of distributed computing environments.
• Experience managing executive customer relationships and key business stakeholders.
• Experience with IT compliance and risk management requirements (e.g. security, privacy, SOX, HIPAA etc.)

Responsibilities

• Own the Application Modernisation workstream end-to-end: domain decomposition strategy, service boundary definition, API design, solution architecture, and delivery governance.
• Lead the decomposition of a ~30-year-old Oracle monolith into business-modelled domain APIs.
• Define and sequence the domain teardown across multiple business units, managing dependencies and minimising disruption to consuming applications.
• Design production, web-facing APIs with clear versioning strategies that avoid breaking existing consumers during progressive migration.
• Navigate the tension between future-facing domain contracts and pragmatic v1 designs that limit application rework and regression risk.
• Establish the end-to-end modernisation process: from legacy discovery and domain mapping through to API specification, solution design review, and cutover planning.
• Collaborate with the Agentic AI workstream lead to define how AI-assisted discovery integrates with human-led business architecture and domain design decisions.
• Advise senior customer stakeholders on architecture direction, sequencing trade-offs, and how much change to absorb per phase.
• Serve as the senior technical authority on legacy decomposition, working across modernisation architects, application developers, data engineers, and customer SMEs.
• Mentor and uplift team capability in legacy modernisation patterns, domain-driven design, and API-first delivery.
• Establish and maintain technical governance: solution design reviews, domain API design standards, and change impact assessment processes.
