About Wolt

At Wolt, we create technology that brings joy, simplicity and earnings to the neighborhoods of the world. In 2014 we started with delivery of restaurant food. Now we’re building the delivery of (almost) everything and you’ll find us in over 500 cities in 30 countries around the world. In 2022 we joined forces with DoorDash and together we keep on dreaming big and expanding across the globe.

Working at Wolt isn’t always easy, but it’s definitely exciting. Here you’ll learn more, build more, and ship more than in most other companies. You’ll be challenged a lot, but also have a lot of fun on the way. So, if you’re a self-starter with drive and entrepreneurial spirit, this could be the ride of your life.

We’re seeking a Machine Learning Engineer to join our cross-functional Logistics department within the Courier Group. The team works on developing critical areas for logistics, including order assignment and delivery estimates, aiming to improve customer experience by efficient order allocation and improving delivery estimates.

Day-to-day in this role you’ll:

• Build the ML infrastructure to develop, train and deploy Wolt’s Logistics models from consumer facing estimates to operational estimates;
• Work end-to-end, from use case design to implementation, delivery and monitoring of your solutions;
• Maintain our production ML stack and raise the team’s ML engineering excellence bar;
• Liaise with Wolt’s ML Platform team to adopt different ML technologies and to create technical requirements for their solutions;

Our humble expectations*

• You bring solid experience in scaling solutions, monitoring ML stacks and troubleshooting ML deployments to the table. You can help with the technical issues the teams encounter;
• You are experienced in implementing real-time inference ML models in production;
• Good understanding of ML and MLOps principles as well as Software engineering experience in Python should complete your profile;
• Experienced in Docker, Kubernetes, workflow orchestration tools (e.g. Flyte), model and experiment registries (e.g. MLflow) and model serving systems (e.g. Seldon);
• You have solid communication and collaboration skills and are experienced in coordinating initiatives with your team and main stakeholders.

What we offer

You will own and drive technical solutions within the ML engineering space for the Logistics department, ensuring they are robust, scalable, and aligned with business goals. With a strong ability to work independently, you’ll take ownership from ideation through delivery.
