Senior Data Scientist - Technical Lead

Job description

We are looking for a Senior Data Scientist - Technical Lead to join our ranks. You will become a crucial member of one of the Crunch Data Teams and work alongside the team's Project Owner to steer several projects in the right direction.


As a Technical Lead, you take up a two-fold role.


First of all, we bestow you with the responsibility of guaranteeing that the solution works – meaning that it solves the problem and generates value in a robust and cost-efficient way. You assume technical leadership over a project and help the Project Owner translate the business and technical challenges into sizeable chunks of data science wizardry.


On top of that, you coach more junior team members and act as a sounding board. You coach them regarding the technical challenges of a solution and their communication with different internal and external stakeholders.


We are looking for an experienced data scientist with a proven track record in advanced analytics cases. You have a solid understanding of how businesses operate and know how to use this knowledge to select the most suitable algorithm and architecture for the task at hand. You have a general understanding of software development and database design, enabling you to ensure that a complete solution is robust enough given the context in which to deploy it. Moreover, you are open and eager to share your knowledge and experiences with more junior team members to help your team succeed.


The successful candidate focuses on providing business value. To do so, you understand how to play to your team member's strengths and help ensure each task is done by the right person. You are unafraid to get your hands dirty and lead by example.


You will mainly be working on data-centric projects in retail & e-commerce, so experience in said or related industries is, therefore, a big plus.
