Job Description

/n

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

/n

1. 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 explicit, 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 on-site in South Australia for approximately 1–2 weeks for workshops, stakeholder interviews, and discovery sessions.

/n

Engagement type: 3-month contract at this stage.

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 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

- Strong 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
