We're looking for a Senior backend developer (Python) to be part of our Engineering Team. We are building a "data pipeline as a service" service that aims to deliver raw data, reports, and automated decisions to our clients' data warehouses or tools. We do this around a business niche - mobile marketing - that involves highly generalizable business processes and vast amounts of data. This position is ideally in Berlin. Remote can be considered if the candidate is able to work in the CET zone. Depending on seniority and experience, as the first full-time engineer of our new product, you might get the chance to shape and lead the future tech team.

Who Are We And What Do We Do

For User Acquisition Specialists, Data Analysts and Marketers fighting through the noise and gaining the attention of potential mobile users in this hyper-competitive market is a challenge.

This is expensive and at Tenjin we help democratize the possibility of success for new and upcoming apps by offering a much more economical GDI solution. We have helped some of your (and the world's) biggest apps.

Leveraging on our highly regarded reputation within the gaming and mobile advertising ecosystem globally, we launched a new product, Growth FullStack and this role if for this new product. Growth FullStack is an ETL product that allows mobile developers to take data from any source and store it in their data warehouse of choice. It is designed to turn data into powerful insights that drive growth for their business. With Growth FullStack, mobile publishers can now focus on building great games without spending time and resources dealing with complex datasets and hiring in-house data engineering teams.

Remote working is in our DNA. We are a diverse and highly collaborative team based all around the world. Our Headquarters are in San Francisco and Berlin, but we also have team members based in Atlanta, Chicago, Toronto, Shanghai, London, and Tokyo.
