About Calexi
There comes a time in every campaign when the dust settles, the noise fades, and you look around to see who is still beside you. That is when you know who you are fighting with and what you are fighting for.
At Calexi, we know that feeling well. We have stood shoulder to shoulder in the toughest places where trust is earned, not issued, and where the margin for error is measured in more than numbers. We are a team built from those moments: people who refuse to quit, who steady their hands when the work gets hard, and who take pride in leaving things better than they found them.
We are more than a consultancy. Yes, we solve complex problems for Defence, government, and industry, but we also build. We design, test, and create systems and technologies that strengthen the digital backbone our nation relies on. Our solutions are shaped by the same curiosity and craftsmanship that define our people: practical, precise, and built to serve something larger than ourselves.
What unites us is not just what we do; it’s why we do it. We believe in service without ego, in the power of knowledge shared, and in the quiet confidence that comes from mastering your craft.
This is Calexi forged in purpose, driven by integrity, united by the belief that together we can build a safer, smarter, better world.
Purpose of the Role
The purpose of this role is to design, integrate, and sustain robust ICT systems that enable mission-critical operations for Calexi’s Defence, government and industry clients. You will work directly with customers to deliver end-to-end systems engineering outcomes across architecture, implementation, and sustainment. The role requires strong technical depth, attention to detail, and an understanding of how security, performance, and reliability intersect in complex environments. This is a hands-on engineering role that blends design, operations, and assurance. You will represent Calexi’s values in every interaction delivering capability that works, that lasts, and that earns trust through performance.
Veteran Commitment
Calexi proudly supports Australia’s veteran community. We recognise the unique leadership, resilience, and mission-focused mindset that veterans bring to our teams. We actively welcome applications from veterans, reservists, and Defence partners seeking meaningful roles in secure ICT, cyber, and engineering domains.
