End-to-end ownership: you build it, run it and fix it

Our engineers own the full life-cycle of the products they build — from release to maintenance. This means ownership and accountability from every engineer in our team.

As we’re running a real-time platform with real world implications that require constant monitoring, we must move smart and fast. We deploy 50-100 times a day. It leads us to develop small, incremental changes at a time and ship value to our customers fast. Our engineers always decide when they deploy so there aren’t hoops of approvals to jump through.

Teams decide the tech they use

We work with a wide variety of technologies. In fact, teams own their technology choices. We value building scalable and robust solutions. 

The most common technologies include: Python, Kotlin, Scala, React, Typescript, and Swift, though we have a bit of Rust, Golang, Flutter and C++ hidden in our services. 

We run everything on AWS, with Kubernetes and a long list of infrastructure automation and various databases (like Mongo and Postgres) to boot. We rely on Kafka to power our data streaming needs.

We’re built upon continuous learning

We also stay curious and share learnings. Here are some of the ways we learn from each other and work together:

• Product Hour: Biweekly Friday knowledge-sharing sessions where we get together to have food and drinks and watch presentations from teams on a variety of topics

• Product Week: A week full of awesome sessions, workshops and team-building sessions to help us come closer as a cross-functional Product Development team

• Wolt Hackathons: In Hackathons, we get together in small cross-functional groups to join forces – building great things together, having fun and innovating

• Competence leads: For our bigger technologies we have competence leads who spend a part of their time codifying best practices, mentoring and reviewing work, and building tech communities inside Wolt

• Tech talks: Internal and external tech talks are our way to share technical knowledge and stories, while sharing learnings and tips on solving different challenges

It’s a journey full of growth

Personal growth is important to us. We want everyone to feel like they’re learning, growing and becoming better in whatever they want to focus on. We believe in giving people the freedom to pursue their interests for the betterment of us all at Wolt. 

To help with this we have regular one-to-ones with team leads and give space for adventuring outside of our comfort zones. We encourage everyone to delve outside of their competence — participating in other team’s projects is encouraged whenever possible, and also many of our engineers have moved teams while at Wolt.

We’re an open community, and we embrace questioning and opinions. Share yours, discuss, learn and grow.
