Job Description

We are looking for an experienced Senior Software Engineer who can develop production-level microservices in Python to join our Delivery Promise team in Logistics. 

Delivery Promise is a cross functional team consisting of software engineers, applied scientists and product, design, and analytics folks. Our team works on developing and deploying machine learning models at scale for estimating different parts of the delivery journey that make up the delivery promise we make to our consumers and merchants as well as on designing and running experiments to evaluate their performance. The team is at the forefront of multiple cross group initiatives across Wolt in providing new and flexible ways of delivery to offer better selection and affordability to our customers.

This role is quite a special one because you will be a key player in solving complex problems related to our delivery estimates in Logistics, ensuring our ML services are performant and available at scale, and that we continuously run multiple consumer-facing A/B experiments as well as randomized Logistics experiments.

Delivery Promise services reside at the intersection between our core Logistics, Consumer, and Merchant platforms offering a diverse set of interesting challenges across multiple domains in Wolt. You will have great potential to make a significant impact by tackling complex problems and building new services and solutions that bring our customer experience and operations to the next level.

📍This role can be based in one of our tech hubs in Helsinki, Berlin, or Stockholm. Read more about our hybrid and remote setup here. If you live outside of these countries - don't worry! We provide relocation support to help you make your way to Finland, Germany, or Sweden.

Qualifications

You might be the one if you are an engineer with experience designing and building top-class software and production-level microservices with expertise & enthusiasm towards working with Python from the get-go and willingness to learn other modern languages such as Kotlin as well if needed. 

We mostly work with Python (Flask & FastAPI), MongoDB, PostgreSQL, Kafka, Redis, and appreciate it if you understand what it takes to build and operate scalable software services in production. Our massive backend software is powered with Kubernetes in AWS so proficiency in these platforms or similar and cloud infrastructure is a huge plus. 

But what truly sets you apart is your ability to tackle big challenges together, envision scalability and availability, and dare to question conventional decisions. We are looking for dedicated people who aim to write modern, testable and maintainable code, are detail oriented pragmatists with a positive attitude, don’t shy away from going outside of their tech comfort zone, and demonstrate curiosity and willingness to keep continuously learning.🌟

In addition to technical expertise, we expect you to be a product-oriented problem solver, a good communicator, willing to collaborate with people in- and outside of your own team, and keen to bring up issues in a constructive manner to the team and to Wolt at large. We work with high ownership in small teams where each team member works around the whole SW development life cycle. 

We value the unique perspectives and skills you bring to our adventure, and we're excited to see what you can achieve with us!👥🚀

Additional Information

The position will be filled as soon as we find the right person, so make sure to apply as soon as you realize you really, really want to join us!

The compensation will be a negotiable combination of monthly pay and DoorDash RSUs. 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.
