Job Description

Analytics at Wolt is a business-critical competence team that covers three different teams - data science, product data analytics and business intelligence. In 2022 we’re going to further scale our data science operations at Wolt. We're now looking to double our current Data Science team and searching for Data Scientist, Operations Research to join our competence team of 40+ professionals working from Helsinki, Tallinn, Berlin, Copenhagen and Stockholm all united by our excitement to put Wolt’s valuable data assets into everyday use.

What you will be doing as a Data Scientist, Operations Research at Wolt

Logistics is one of the more complex parts of Wolt’s business and is a crucial building block of Wolt’s technology platform. Our logistics platform is responsible for courier task allocation, and generating delivery estimates that our customers, couriers, and merchants see. A more efficient logistics platform would benefit everyone in our ecosystem: our 130 000+ courier partners, our 60 000+ merchant partners, and our 18+ million customers. 

The logistics platform is being developed by a cross-functional team and by a mix of Data Scientists, Optimization Algorithm Developers, and Backend Engineers. It connects Courier Partners to tasks through our in-house route optimization service, which in turn relies on the delivery estimates that we generate for each step of the delivery process. All the different parts of the system come together to automatically manage customer expectations and delivery efficiency.

You would work as an embedded Data Scientist, Operations Research in the Logistics Optimization team, which owns the route optimizer, and the delivery estimates - your focus would be on the optimizer. You would have an impact on Wolt’s overall business as a key player in envisioning and finding new ways to increase our delivery efficiency while keeping our customers happy with accurate estimates, and keeping our couriers engaged with a steady stream of tasks. As an operations research expert, you would find where potential problems lie through data analysis and would work with the rest of the team to get proposed changes implemented. You’d then plan and implement the live logistics experiments needed to verify the hypotheses, and understand the business impact of the changes.

Our humble expectations

• You have plenty of hands-on experience with production-level operations research projects. From identifying opportunities and developing hypotheses, to finding ways to validate and test them, ultimately driving their implementation and measuring the impact.
• You’ve worked with experimentation before, designing, implementing and analyzing experiments (AB-testing and switchback experiments)
• Demonstrated ability to improve highly complex systems/solutions working together with experts from other fields
• You’ll have fluent programming skills in Python, which is our main language for data science projects, and experience with databases (SQL). And you’re comfortable with the rest of the tools of the trade.
• You’re analytical and curious, we’re looking for a self-starter with a drive to get things done. Also as well a good communicator, willing to collaborate with people in- and outside of the team
• Ideally, you’ll also have a degree in a field relevant to operations research or data science 
• We value delivery logistics business understanding, preferably deep domain experience.

Our offering to you

• Leave your mark in building the most efficient logistics optimizer in the industry.
• You can choose the location from our tech hubs Helsinki or Berlin, or you can work entirely remotely anywhere in Finland, Sweden and Estonia. You have the chance to decide the ways of working —· a hybrid, at the office, or remote within the location above. Read more about our remote setup. 
• In addition to our country-specific benefits, our compensation package includes a monthly salary based on your expertise and stock options. The latter makes it exceptionally easy to be excited about our company growing and doing well, as you'll own a piece of the pie.
• At Wolt, you’ll get to work in a company culture where we take ownership beyond the obvious, do common things uncommonly well, we think big but stay humble, do right by people, we treat others kindly and justly, recognise that if we don’t learn, we won’t stay still but fall behind and keep in mind that Luke was Yoda’s greatest achievement.
