Cosmian is looking for a passionate professional with a strong interest in Rust and cryptography.

Job Description

Your main responsibility will be to work along lead engineers on the engineering and development of Cosmian software solutions. The software is developed in Rust using the latest tools and techniques and mostly consists of backend code. As part of your daily activities, you will be working on multiple aspects of the backend code, from API servers to cryptographic libraries. Some WASM or python development may be required too.

The job is full-time and located in Paris, France, but knowledge of French is not mandatory. Remote work is possible with specific requirements. The package includes the full French social security and work protection benefits (CDI) as well as stock options (BSPCE). 

Salary will be adjusted according to qualifications, experience and work location, but the typical salary would be in the 40-50K for a developer based in Paris. Depending on the number of public holidays on workdays there are around 32-35 days off per year. Taking home office days is possible without bureaucracy.

Required skills/qualifications

You must be passionate about Rust (and software development in general), have 2-3 years professional experience or relevant experience on an Open Source Project as a major contributor. We expect that you have already worked in a team, know how to use modern CI, and are able to perform some basic git and linux command line wizardry.

Significant experience in Rust is not mandatory but significant experience in a major system/backend language will be required.
