Senior Software Engineer (Node.js)

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. Our culture is one of our greatest strengths: open, direct, collaborative, and built on trust and continuous growth.
