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.\nWe 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.\nWe 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.\nOur 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.\nA note about MZLA and Mozilla: MZLA Technologies Corporation is the nonprofit-owned company behind Thunderbird and part of the Mozilla family. MZLA is separate from Mozilla Corporation and has its own compensation programs, benefits, and employment policies.\nTo learn more, visit www.thunderbird.net\nThe opportunity\nWe are looking for a finance leader with a strong accounting or controllership foundation and the breadth to lead financial planning and analysis, finance operations, and organization-level decision support.\nAs MZLA grows across donations, subscription services, enterprise offerings, and international operations, our financial needs are becoming more complex.

This is a hands-on functional leadership role for someone who can provide experienced financial judgment, develop an established team, and remain close to the details while helping build the systems, controls, reporting, and finance practices the organization needs for its next stage of growth.\nThis role requires regular working-hour overlap with the COO, finance team, and other colleagues across North American time zones.
