Why Thunderbird?
Thunderbird is one of the world’s most trusted open-source email applications, empowering more than 20 million people globally. At 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.
A note about Thunderbird and Mozilla: Thunderbird Technologies Corporation is the nonprofit-owned company behind Thunderbird email and a growing portfolio of products. While part of the Mozilla family, Thunderbird is a separate entity from Mozilla Corporation and Mozilla Foundation with its own compensation programs, benefits, and employment policies.

The opportunity
We 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.
As Thunderbird grows across donations, subscription services, enterprise offerings, and international operations, our financial needs are becoming more complex. We need stronger integration across accounting and FP&A, experienced oversight of emerging revenue models and tax obligations, and clear financial analysis that helps leadership understand performance, risks, tradeoffs, and decisions.
Reporting to the Chief Operating Officer, the Senior Manager will serve as Thunderbird’s most senior finance professional and directly manage our Senior Staff Accountant and Senior FP&A Analyst. 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.
