Join Calexi
At Calexi, we’re building a different kind of Managed IT and Cyber Security company. We look for people who enjoy solving problems, taking ownership and delivering technology that genuinely helps our clients succeed. Whether you’re supporting users, securing Microsoft 365 environments or helping Defence contractors meet compliance requirements, your work will have a real impact.
We value curiosity, integrity and accountability. We hire people who communicate clearly, keep learning and take pride in delivering reliable outcomes. If you enjoy working with customers, improving systems and building secure technology that people can depend on, you’ll fit in at Calexi.
As a veteran-owned Australian business, we are committed to recruiting, supporting and retaining veterans. We encourage veterans to identify their prior service during recruitment and provide flexible working arrangements, mentoring, tailored onboarding and support for reservists. We are proud to build a workplace where Defence experience is valued and every team member has the opportunity to grow.
Who We Are
Calexi is a Canberra-based Managed IT and Cyber Security provider supporting Defence contractors and regulated organisations across Australia. We deliver managed IT, Microsoft 365, cyber security and Defence compliance services through Australian security-cleared engineers who understand the environments our clients operate in.
We’re values-driven and focused on building long-term partnerships with our clients. We hire people who take ownership, enjoy solving problems and are committed to delivering secure, reliable technology that keeps organisations productive and resilient. At Calexi, we believe the best outcomes come from trusted people, practical solutions and a commitment to continuous improvement.
