Remote (Australia-wide) + 1–2 weeks on-site in SA

n

3-month contract

n

This role is open to an experienced Mainframe Application Assessor to lead an architecture-focused assessment of a legacy mainframe application for a South Australian Government department.

n

This is a review and advisory engagement, not a development role.

n

You'll evaluate the current-state architecture of a mainframe application, map its dependencies, and deliver a transparent, well-reasoned modernisation recommendation to guide the department's future ICT direction — informed by real understanding of the technology, not just a template.

n

Location: Based anywhere in Australia, remote-friendly. You will need to be in office in South Australia for approximately 1–2 weeks for workshops, stakeholder interviews, and discovery sessions.

n

Engagement type: 3-month contract at this stage.

n

What you'll do:

n

n
Assess the current-state architecture of a mainframe application, including its technology stack (COBOL, PL/I, Assembler, CICS, IMS, DB2, VSAM, JCL)
n
Map integration points, data flows, and upstream/downstream system dependencies
n
Assess technical debt, supportability, licensing exposure,



and end-of-life risk
n
Apply a 6R modernisation framework (rehost, replatform, refactor, rearchitect, rebuild, retire) to develop a disposition recommendation
n
Identify risks, constraints, and indicative costs/effort for the recommended path
n
Run workshops and interviews with department SMEs, vendors, and platform owners to validate findings
n
Produce a comprehensive findings report and present to governance/steering forums
n

n

What you'll bring:

n

n
Demonstrated experience assessing or architecting mainframe-based enterprise applications
n
Working knowledge of mainframe technologies (COBOL/PL1/Assembler, CICS/IMS, DB2/VSAM, JCL) — hands‐on coding not required, but you need to genuinely understand the stack to assess it credibly
n
Experience applying modernisation or cloud migration frameworks
n
Robust stakeholder engagement skills — comfortable running workshops and presenting to senior government stakeholders
n
Excellent report‐writing and documentation skills
n
Prior government or regulated‐sector experience highly regarded
n
