Data Scientist, Operations Research, Wolt

Wolt is looking for Data Scientist, Operations Research to drive improvements on our logistics optimization process.

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. 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.

PhD position in Computer and Systems Sciences (University of Stockholm)

Please note, the deadline is April 15th, 2020!

Project description 
Sweden aims to transition to carbon neutrality by 2045 by relying on a 100 % renewable power system. Such a system will include more variable renewable energy sources, such as solar and wind power, and will function differently than the present one due to intermittency. In particular, flexible producers, e.g., hydropower plants, and the transmission network will become more important in balancing the system. This enhanced leverage for flexible producers increases their potential for market power and thwarts society’s objectives.

This project will develop game-theoretic models adapted to the Nordic power system both to identify such conflicts and to propose proactive mechanisms to mitigate their welfare losses. The ideal candidate should have a background in a quantitative subject, e.g., economics, operations research, or systems analysis, with programming and data-handling experience. Knowledge of electricity markets, energy policy, and environmental issues is also desirable.
