Engineering /
Back is a young software company from Berlin with the mission to enable companies to focus on what they do best. We’re building a collaboration and automation platform to untangle repetitive questions and workflows around the workplace. 

You will join our experienced engineering team to build our machine learning pipeline and develop some of our first machine learning supported features. If you are excited about building highly scalable solutions built on a modern stack using best practices then this role is perfect for you.

This position is based in our growing HQ in Berlin.

🔨 What you will do

    • You will take ownership of automation features from the beginning - understanding the problem - to the end - deploying the model on production -.
    • You will setup the environment to speed up our machine learning development.
    • You will implement and tune state-of-the-art ML models to get the best results given the available data.
    • You will effectively communicate and document your approach, progress, results and challenges with the team.
    • You will help us grow the machine learning team: enforce best practices, interview candidate, etc.

👩‍🔬 Who are we looking for

    • You can quickly grasp the business context of the problem and using your knowledge of how the model is going to be used, you can choose the right evaluation metric.
    • You can dig deep into the data to choose the right dataset split and identify pitfalls arising from non-iid samples.
    • You can combining both your practical and theoretical ML knowledge to set the right priorities when choosing which idea or approach to try next.
    • You find the simplest solution to solve complex problems programmatically.
    • You find joy in delivering features to your customer rather than doing academic research.
    • You like to work in a team and challenge your choices with your peers.

🦾 What challenges will you face

    • You'll work on complex NLP problems touching multiple domains: multiple language understanding and feature extraction.
    • You'll work on unbalanced datasets, not all our customers are the same size.
    • Our customers have different processes, different vocabulary. You will face dual-domain adaptation problems.
    • The good news: our application generates labeled data and we capture all the signals of our users' interactions, so you'll focus on training models, not labelling data. Yeah!
