About the role

Mozilla Corporation is the non-profit-backed technology company that has shaped the internet for the better over the last 25 years.
We make pioneering brands like Firefox, the privacy-minded web browser.
Now, with more than 225 million people around the world using our products each month, we're shaping the next 25 years of technology and helping to reclaim an internet built for people, not companies.

Own marketing tests end-to-end, leveraging and contributing to our Python-based measurement workflows.
Collaborate with senior ICs to address critical data infrastructure needs, support org-wide migrations, and develop new analytical and measurement solutions.
Develop reporting and monitoring tools that surface business insights and increase visibility into marketing performance and impact.
Along with thousands of volunteer contributors and collaborators all over the world, Mozillians design, build and distribute open-source software that enables people to enjoy the internet on their terms.
Mozilla exists to build the Internet as a public resource accessible to all because we believe that open and free is better than closed and controlled.
Join us to work on the Web as the platform and help create more opportunity and innovation for everyone online.

2-3 years of experience conducting quantitative analyses, ideally within a marketing or growth environment.
