Careers at Core Sentinel
We’re a boutique offensive-security firm built on a simple principle: every engagement is run by a senior, certified tester — no junior bench, no scan-and-send. If you’re a skilled penetration tester who takes pride in doing the work properly and explaining it clearly, we’d like to hear from you.
Why work here
- Real work, real depth. Manual, methodology-led testing across web, mobile, infrastructure and wireless — not box-ticking.
- Senior team. Work alongside experienced, OSCE/OSCP-certified consultants and learn from genuine veterans of the field.
- Variety. Clients across banking, finance, government, defence, health and education — different environments, different challenges.
- Ownership. A small, expert team means your work matters and your voice is heard.
Who we look for
Penetration testers and security consultants with hands-on offensive experience and relevant certifications (OSCP, OSCE, and similar). We value clear written communication as highly as technical skill — our reports are part of the product. Australian work rights and the ability to pass background checks are required for many engagements.
How to apply
Send your CV and a short note about the kind of work you enjoy to info@coresentinel.com. Even if we don’t have an open role right now, we’re always glad to connect with strong testers.
Core Sentinel is a merits-based organisation. We make hiring and advancement decisions on the basis of merit alone — your skills, experience, character and ability to do the work. We are an equal-opportunity employer and welcome applicants of all backgrounds; every application is assessed fairly and on its merits.
