About the job

Most people who face a legal problem do not get help from a lawyer. And for those who do, many find the experience expensive, uncertain and confusing. Josef’s mission is simple and ambitious: to make legal services more accessible for everyone, no matter who you are. 

Josef is an award-winning no-code platform that allows legal teams to easily build, launch and scale automated legal services. Since we were founded in 2019, we’ve used cutting-edge technology to help hundreds of thousands of people solve legal problems, ranging from public transport fines in Australia to domestic violence in North Africa, from complex tax questions in San Francisco to helping people deal with troublesome landlords in New York.

Our customers include in-house legal teams at companies like L’Oreal and Bupa, global law firms like Clifford Chance, law schools like New York University and Melbourne Law School, and legal aid organisations around the world, like Housing Court Answers in New York.

Josef doesn’t just build world-leading tech: we also lead the conversation. We’re regularly invited to present our research at conferences worldwide, including last year at the International Conference on AI and the Law in Braga, Portugal, and at Stanford’s JURIX conference in Maastricht, Netherlands.
