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.
What you'll be doing
In this role, you will be part of Wolt’s Platform department (Core Group), improving and automating operations for the datastores used across Wolt. The Database Reliability Team is responsible for maintaining smooth datastore operations for the data of 45M+ registered users and 170 000+ active venues. Our primary focus is on MongoDB, PostgreSQL, and Kafka, along with other storage technologies used in the company.
As part of the Database Reliability Team you will be responsible for:
- Designing, implementing, and maintaining automation tools and services to eliminate manual work and reduce toil.
- Collaborating with DBRE and SRE engineers to automate processes like database provisioning, alerts creation, and anomalies detection.
- Integrating database-related tools and services with the internal developer portal (Backstage), adding self-service capabilities based on the developers requests.
- Maintaining and improving internal services on top of Kafka used company wide.
- Working with other engineering teams to identify inefficiencies in database lifecycle management and propose technical solutions that simplify their work.
Most engineers on the team have an SRE and DBRE background. In this role, you will work alongside them to identify and automate manual repetitive work done by the team or other engineers working with datastores, and ensure the high quality of existing tooling. You will work closely with other Core teams and gain broad exposure to databases, event streaming, platform infrastructure, and SRE and DevOps best practices.
Our humble expectations
You’ll be a great fit for this role if you have the following skills and experience:
- Strong programming skills in Python
- Good knowledge of Cassandra
- Understanding of SRE best practices: SLOs, availability requirements, and distributed system reliability
- Experience working with Kafka
- Experience working with one of the Cloud providers: AWS / Azure / GCP
- Experience using either a relational database (e.g., Postgres) or a NoSQL database (e.g., MongoDB)
- Strong communication and collaboration skills with the ability to write clear documentation for other engineers
- Familiarity with modern development practices, like IaC and observability tools is a plus
- Go knowledge is a plus
You don’t need to tick every box, but if you see yourself in many of these points, we’d love to hear from you!
Our Ways Of Working
The Database Reliability Team follows an Agile workflow tailored to our needs:
- Quarterly planning: We set priorities together, aligning with company OKRs and our vision for reliability and essential maintenance tasks
- Minimal meetings: To keep engineers focused, we have bi-weekly planning & retrospectives, twice-weekly standups, and ad-hoc project discussions as needed
