Why Janusnet?

For more than 20 years, Janusnet has been developing trusted information security solutions used by government, defence and commercial organisations across Australia and around the world.

We're big enough to work on complex, meaningful security challenges, but still small enough that every engineer has genuine influence over the products we build.

Here, you'll have the opportunity to challenge ideas, innovate, and help shape technology that protects organisations where security matters most.

If you're ready to build software that genuinely makes a difference, and want the opportunity to influence products from concept through to release we'd love to hear from you!
