About This Role

As a Staff Solutions Engineer for Firefox Enterprise in France, you'll bridge technical sales and deployment, helping large organizations adopt Firefox with tailored security and management. Your work directly impacts how critical sectors like finance and government secure their browsing environments.

💡 A Day in the Life

A typical day might start with a call with a French bank's IT security team to discuss their browser policy needs, followed by designing a proof-of-concept for Firefox deployment with GPO and SSO. Afternoon could involve creating a reference architecture for a public sector client and collaborating with the sales team on a proposal for a critical infrastructure operator.
