Join Calexi
At Calexi, we look for the ones who never stopped asking why. The thinkers and the tinkers. The ones who pull things apart just to understand how they work and then rebuild them better. We want people with grit, with integrity, with a fire in their belly for technology and a hunger to learn. People who can communicate clearly, act decisively, and never settle for good enough. Our team is made up of those who lean into complexity, who thrive in the grey, who grow with us and push us to grow in return. If you are the kind of person who wants to leave your patch of the world better than you found it, we want you on our team.
Who We Are
Calexi is a Canberra-based consultancy delivering cyber security, engineering and ICT solutions for government, Defence and critical infrastructure. We work where trust matters most, bringing clarity, precision and unwavering focus to the most complex and high-stakes environments.
We are values-driven and purpose-led. We care deeply about what we do and who we do it with. We hire people who want their work to mean something—people with grit, curiosity and the courage to challenge the status quo. People who lean into complexity, speak with conviction and never settle for good enough. At Calexi, we believe in doing work that matters, for clients who demand the best, with a team that backs each other to deliver.
Who We’re Looking For
We hire people who:
- Thrive on complex problems and high-trust environments

- Value precision, integrity and follow-through

Calexi supports the employment of veterans and reservists. We value the unique skills, adaptability and leadership that Defence service fosters. Veterans are encouraged to apply, and voluntary disclosure of prior service is respected and appreciated.
