- Advising customer architects, engineering teams and senior stakeholders
- Supporting workload prioritisation, migration waves and cutover risk
- Applying AI-assisted and Generative AI approaches to legacy code transformation
- Creating reusable modernisation playbooks, frameworks and reference architectures li>

What we're looking for:





You'll bring strong experience across both traditional mainframe environments and modern cloud technologies, including:

- 7+ years' mainframe experience across technologies such as z/OS, COBOL, PL/I, JCL, CICS, IMS, DB2 and VSAM
- 3+ years' AWS or equivalent cloud experience, ideally across migration and modernisation
- Experience with AWS Mainframe Modernization, DMS, SCT, Step Functions and/or Lambda
- Mainframe modernisation experience across replatforming, cloud-native refactoring or automated code transformation
- Experience migrating DB2, IMS or VSAM environments into cloud-native databases such as RDS, Aurora or DynamoDB
- Strong customer-facing consulting capability across complex enterprise transformation programs
- Exposure to AI-assisted code analysis, transformation or Generative AI tools would be highly regarded

Why consider it?

This is an prospect to work at the intersection of mainframe engineering, AWS cloud and AI-enabled modernisation, helping some of Australia's largest enterprise organisations transform business-critical legacy environments.

You'll remain highly hands-on technically, while also acting as a trusted advisor to customers and contributing to the broader modernisation capability.
