Headquartered in Paris, with additional offices in New York, London, and Singapore, Jus Mundi serves over 150,000 users, including top law firms, multinational corporations, government bodies, and academic institutions in more than 90 countries.

What Makes Jus Mundi the Place to Be
About the Role
Jus Mundi is looking for talented developers to join their EPD team (Engineering, Product and Design).
This is the opportunity to join a team not only driven by the tech, but working all together to make the best product in our field. This is not only words on paper: our metrics are not the number of lines of codes, but the value delivered in prod.
Concretely, it means that developers are owner of the features they ship, and can structure them in partnership with the product team and the design team. Writing the code is only a part of this thriving mission where you directly contribute to the transformation of the legal industry.
The Team
EPD team is split into mission driven squads, and you will be joining one of these squads alongside with other talented developers, a Product Manager, and an Engineering Manager.
Squads are also working in close partnership with the Platform Team, bringing expertise on the more technical topics.
There are several open positions, especially in 2 squads:
Your mission at Jus Mundi
As part of the Engineering Product and Design team, you will alternate between code writing and feature building. Every developer is regularly tech owner of an epic, meaning he follows every step of the feature, from design to Go To Market. Of course, you will not be alone into this journey, and you will be supported by the whole team at every step.
This is an incredible opportunity to challenge and shape the extraordinary product we are building, and measure the real impact of our work.
This position is for you if you are excited by challenges beyond the code, if you shine at building solutions to real problems, and if you are entertained by collaborative delivery rather by complex algorithms.
