Senior Software Engineer

Talent Acquisition Lead @ Checkbox | Ex-Software Engineer The Company Checkbox is a VC-backed technology start-up entering our scale-up phase following a successful Series A funding round. Our mission is to enable meaningful work for all by empowering non-technical teams to build and automate their own workflows. We believe the power of digital creation should be accessible to everyone, not just IT teams. Our no-code platform is used by global organisations including Deloitte, Coca-Cola, Allianz, and the Singapore Government. More recently, we expanded our offering beyond automation with the launch of our AI-powered Matter Management product – the “JIRA for lawyers.” This forms part of our broader vision to become the Legal Service Hub within organisations, powering how legal work is raised, allocated, managed, and resolved. As a company, we are a tight-knit, high-performing team of around 50 people across Australia, the United States, and Asia, including Forbes 30 Under 30 co-founders and leaders from global SaaS success stories.
