HR Director of GravitHy
At GravitHy, we’re not just building a factory — we’re creating a new industry: cleaner, more inclusive, and more ambitious. Today, we are a young, dynamic, and deeply human company, where more than a dozen nationalities work together every day with respect and enthusiasm. We believe that diversity is a strength, inclusion is a force, and gender equality is a given. We’re proud to be based in Paris and Marseille — two vibrant, globally connected cities that offer an exceptional quality of life. But above all, what brings us together is our mission: to decarbonize the steel industry — a high-emission sector, but an essential one. If you’re looking to give meaning to your career, to join an extraordinary industrial and human adventure, or if our mission simply inspires you: our culture will welcome you.

What we like in Paris:
- Intellectual effervescence and access to innovation networks.
- A modern, flexible and connected work environment.

GravitHy welcomes talent from around the world.
Depending on the positions and individual situations, we may be required to support international mobility initiatives.
Yes. If you are interested in several positions, do not hesitate to apply for each one of them.
Our HR team will study your profile as a whole.
Some offers are located on a specific site, others are open to both locations.
We value internal mobility and the bridges between our offices.
Yes, GravitHy welcomes interns and apprentices in various fields: engineering, communication, HR, etc.
The offers are published on our website, but you can also send an unsolicited application.
Of course! If no offer matches your profile at the moment, you can submit an unsolicited application via the contact form available on our site or by writing to recruitment@gravithy.eu. We will study it carefully.

Each new employee benefits from a personalized onboarding process, including:
- An HR welcome, a security presentation and an overview of the company.
- Meeting with the teams.
- Access to an internal resource platform.
- A regular follow-up during the first weeks
(This process can be enriched during your integration to promote your skills development and well-being within the team).

- Support functions: human resources, finance, purchasing, etc.
We are looking for committed, curious talents capable of evolving in a fast-growing environment.
Skills in project management, technical coordination, or even in the regulatory and industrial environment are particularly appreciated.
French is an important asset, especially for interacting with local partners, suppliers or institutional stakeholders.
However, our work environment is multicultural and the main language used internally remains English, particularly in technical and cross-functional exchanges.
A good understanding of both languages is therefore strongly recommended to fully integrate into our teams and projects.
Yes, remote work is possible at GravitHy.
We offer a hybrid work mode, combining on-site presence and remote work, depending on the missions and the organization of the teams.
