The companies here are whoever each fund lists on its portfolio jobs board, so established names sit alongside new ones; Antler's global board is narrowed to its Australian companies. A role disappears when the board drops it. We take no fee and have no part in hiring: each listing is the company's own, and the company is who you deal with.

Running an Australian security startup and hiring? If your investor runs a portfolio board, your roles will appear here within a day of being listed there. Otherwise get in touch.
