Why Thunderbird?

Thunderbird is one of the world's most trusted open-source email applications, empowering more than 20 million people globally. At MZLA, the team behind Thunderbird, we build privacy-respecting communication and productivity tools that help people manage their digital lives while staying in control of their data. We are open source by design. Our products are developed transparently and in collaboration with a global community of contributors, and that same spirit shapes how we work: collaboratively, inclusively, and with a shared commitment to putting users first. We are a small but growing company of 70+ people distributed across seven countries. As Thunderbird evolves beyond a single desktop application, we are expanding across desktop, mobile, paid services, and new product experiences that help people and organizations work more effectively without giving up control to big tech ecosystems. Our revenue model combines user donations, which help keep Thunderbird's apps freely available, with paid services that cover the costs of hosted offerings while supporting long-term sustainability and continued innovation.

The opportunity

We are looking for a finance leader with a

  • Own financial oversight of payroll across multiple providers in partnership with the People team.
