Job description

Senior Software Engineer | Backend Golang

The Company

Checkbox is an Aussie Scale-up success story with a mission to enable meaningful work for legal. To achieve this, we built a no-code automation platform with the belief that the power of digital creation needs to be accessible to everyone, not just IT teams. Whilst our mission is big, our focus is sharp. Our customers today are primarily in-house legal departments from companies including Disney, BMW, Pinterest, and Coca-Cola.

Recently, we expanded our offering to not only help people do meaningful work, but manage it too. This came with the launch of our AI-powered Matter Management product – the “JIRA for lawyers”. This is part of our broader vision to be the “Legal Service Hub” for organisations, responsible for how legal work is raised, allocated, managed, and resolved. We believe that one day the Legal Service Hub will be as ubiquitous for legal teams as the CRM for commercial teams and we believe that Checkbox will be the market leader for this.

As a company, we are a young and tight-knit team of about 90 people across APAC and the United States. Our culture is one of our superpowers. It's what people talk about when they join us, work with us, and leave us.
