Senior Backend Engineer

About Us:

Clue is the world’s fastest growing period tracking and fertility app. We are a 45-person, VC-­backed startup based in Berlin. Every month, millions of users track data about their bodies in Clue’s iOS and Android apps. With every data point, Clue users gain knowledge about their own health, impact the entire community of Clue users, and advance reproductive health care globally. Here’s some media coverage about us. We at Clue are committed to a culture of inclusivity and mutual respect.

The role:

We are building a team of backend and data engineers to take us to the next level of growth, both in terms of users and features. We’ve grown quickly to serve millions of users and expect to grow even faster over the coming years, as we evolve from being a period tracker app to a full-fledged female health platform.

Our backend is deployed as a growing array of microservices, running in docker containers on AWS, largely written in TypeScript on Node.js. For data storage and queuing we use a combination of Postgres, S3, SNS/SQS, RabbitMQ and more. We’re constantly working to improve our infrastructure to meet new scalability requirements, streamline development, improve our operations and -- last but not least -- develop powerful new data analysis features. Going forward we expect to run more diverse services in different languages where needed, and moving to more scalable data stores.

Your role would be to evolve, maintain and develop new features to our backend and infrastructure with a dedicated team of skilled engineers. You would also work closely with our product and data science teams.

Data science and analytics play an important role at Clue, both for our business and to improve our product with personalised insights based on users’ own data. Any experience with big data analysis and data pipelining is most welcome.

We need your help to take Clue to the next level. Apply now! We look forward to getting to know you. :)
