How do you make our customers happy?
Recommendations are at the heart of shopping at bol.com. Even veteran shoppers can use a little help when there are 41 stores and over 20 million items to choose from. That’s why we deploy a recommender system that helps customers discover and choose the perfect products for them. From suggesting products based on viewing and buying signals to providing deep category entrances and adding a touch of personalization, recommender systems can transform the customer journey from an uncomfortable paradox of choice to a smooth and enjoyable activity. We see this as an integral part of the customer experience. And we’re fortunate that our customers provide us with all the input we need to continue improving our recommendations on a daily basis. Can you further improve and run bol.com’s recommender systems for millions of items and users?
Your responsibilities to provide the best recommendations to our customers
As a Senior Data Scientist in the recommendations team, you improve the bol.com recommender systems that drives our customer experience and coach and mentor team colleagues. Together with the data scientists, data engineers and software engineers on your team, you apply your ML and statistical expertise and experience to develop and experiment with applied ML systems that drive conversion and sales, using metrics such as CTRs and order rates. You accomplish this with state-of-art learning technologies (such as neural nets) as well as old-fashioned bandits and linear learners. Whatever gets the job done because, you guessed it: we take a pragmatic approach. Pragmatism is also necessary in your communication style. You’ll sharing your ideas with a broad audience, from store specialists to C-level executives, across a large part of our organization (as this is an important business domain, albeit a highly technical one). And of course, we do not conduct data science as an intellectual exercise but in order to add value in a production environment. Given our scale and performance requirements, this also calls for engineering skills.
Bol.com in numbers
Bol.com doesn’t drop numbers to impress, but we do want to put the responsibilities of this position in perspective. We’re talking about
- Sorting through over 20 million products
- For over 9.5 million customers, who
- Can place 17 orders per second, sustained (Black Friday, 2017)
3 reasons why this is(n’t) for you
- Because you want to apply your technical background and applied ML expertise (preferably in recommender systems!) at bol.com scale
- Because you thrive in an inclusive and cooperative cross-functional environment
- Because you think in code and engineering
- Because you’re a 100% academic researcher who considers practical applications inconsequential
- Because you have no affinity with software engineering and shrug when we mention stuff like NoSQL, cloud, and massive parallelization
- Because you only want to work on new things and hate to take care of legacy when needed.
