Senior Physical Security Consultant

Senior Security Consultant

Core42 | $150,000–$170,000 + super + performance bonus

The work

You will lead security advisory work on Australia’s most consequential built-environment programs, including major airports and airside infrastructure, passenger and heavy rail, Defence estate and capability projects, and iconic public places. The work shapes how millions of people move through public space safely, and the security positions you set will be tested by designers, engineers, executives, and assurance reviewers across the project lifecycle.

You will partner directly with both Managing Directors and a team of specialist security advisors on projects that require fluency across executive stakeholders, program managers, designers, and state and federal authorities.

We are a lean team by design — under ten people, senior-led, with no layers between you and the decisions that matter.

What you will lead

• End-to-end security risk assessments — threat, criticality, vulnerability, treatment.

• Translation of risk findings into protective measures architects and engineers can understand, and build into a project.

• Physical security and electronic security design and specifications calibrated to the client's risk.

• The assurance position on high-stakes calls — what is defensible, what residual risk is being accepted, what governance has to follow.

• The senior client relationship on accounts where you are the named advisor.

• Enterprise engagement on non-built environment projects, including with senior executives and decision makers across government and commercial organisations.

• Winning, and delivering work with the support of a broader team.

Why work with Core42

Core42 is not a conventional security consultancy, and working here is not a conventional security career.

We are a small, specialist team advising on some of Australia's highest-profile built environment and public safety challenges, from national infrastructure and major transport corridors to crowded places and high-consequence events. We are the security partner of choice for several large government agencies across their enterprise, and our relationships continue to grow from boardrooms to operations. The work is technically demanding, intellectually serious, and visible in ways that matter.

What makes Core42 different as an employer comes down to a few things that larger firms cannot offer.

Your work shapes the field, not just the project. Core42 publishes peer-reviewed research, contributes to the national conversation on security, and actively works to change how security is integrated into the built environment. When you develop an idea here, there is a direct path from that idea to publication, to practice, to policy.

You work with the founders, not for a hierarchy. Decisions are made quickly, without layers of bureaucratic sign-off. If you have a better way to approach a problem, you say so, and it gets considered the same day. Strategic direction, service development, and firm positioning are conversations, not edicts.

The client base reflects the firm's reputation. Core42's clients return repeatedly, across sectors and projects, because the work is trusted. That means you spend your time delivering high-quality work rather than chasing work — and you build long-term professional relationships with sophisticated clients who value expertise over process compliance.

Your interests get pursued, not managed. If there is a research question you want to investigate, a methodology you want to develop, or a conference you want to present at, Core42 will support it.

The work is high-profile and the team is small. That combination means individual contribution is visible and meaningful. There is no anonymity, and there is no ceiling on impact.

Core42 is the right fit for someone who wants to do serious work, be taken seriously, and help build something that outlasts any single project.

What we are looking for

• Eight or more years across security risk analysis, threat assessment, and assurance on complex built-environment projects.

• Demonstrable depth in both physical security and electronic security design — calibrated to risk, integrated with architecture and engineering disciplines.

• A track record of advising senior client stakeholders directly.

• Fluency with HB167-aligned risk methodology, design-integrated CPTED practice, and assurance frameworks across the project lifecycle.

Compensation and working model

$150,000–$170,000 plus superannuation, with a transparent performance bonus structure on top.

Hybrid working from our Sydney or Perth offices preferred, we will consider applicants from other geographies (South Australia, Queensland, Victoria).

I nter-state travel is expected, but infrequent on a project-by-project basis.
