Want to protect Australia's most sensitive systems?

The custodian of some of Australia’s most sensitive government systems and databases is looking for applicants to fill its top cyber security role.

The Department of Human Services has advertised for a national manager of cyber security as part of a senior executive hiring spree within the agency’s CIO group.

The new cyber boss will enjoy a special level of authority, ranked at the third tier of seniority within the IT division, but still answering straight into the CIO Gary Sterrenberg.

The role had most recently been held by Mitch Levy, who is currently filling a general manager role elsewhere in the group. Glenn Mitchell ihas been acting in the cyber security position in Levy’s absence.

The successful candidate will be "accountable for the current and future strategic plan and strategy for cyber and information security in a fast paced, dynamic environment", leading what the DHS is calling a "new era in technology and service delivery".

They will be expected to manage the "governance, risk and delivery of some of the most critical technological strategies and solutions in Australia".

The cyber security team makes up one branch of what DHS boasts is the largest IT shop in the southern hemisphere, with 3000 staff and an annual budget of $962 million.

The department is also advertising for two general managers at the senior executive service level two ranking who will act as key deputies to Sterrenberg.

It is looking to fill vacancies at the head of its Canberra delivery centre and its production systems delivery centre.

DHS wants candidates with "demonstrated experience, underpinned by strong conceptual thinking, sound fiscal and governance leadership".

One rank down, applications are also open to become the national manager of enterprise architecture within Charles McHardie’s CTO branch.

The role oversees the ongoing sustainment of DHS information and systems, including architectural frameworks, strategy and information security.

DHS is similarly making another call for interest in any of the remaining national manager-level roles within CIOG. Of the 25 national manager positions, 11 are currently vacant or are being filled in an acting capacity while the title holder is seconded elsewhere.

DHS will take applications for the roles until 29 May 2016.
