Senior Python Engineer

at  Wolt Sverige AB

Data at Wolt
As the scale of Wolt has rapidly grown, we are introducing new users to our data platform every day and want this to become a coherent and streamlined experience for all users, whether they’re Analysts, Data Scientists working with our data or teams bringing new data to the platform from their applications. We aim to both provide new platform capabilities across batch, streaming, orchestration and data integration to serve our user’s needs, as well as building an intuitive interface for them to solve their use cases without having to learn the details of the underlying tools.
In the context of this role we are hiring an experienced Software Engineer to provide in one the following workstreams
Data Governance
Wolt’s Data Group has already developed an initial foundational tooling in the areas of data management, security, auditing, data catalog and quality monitoring, but through your technical contributions you will ensure our Data Governance tooling is state of the art. You’ll be improving the current Data Governance platform, making sure it can be further integrated with the rest of the Data Platform and Wolt Services in a scalable, secure, compliant way, without significant disruptions to the teams.
Data Experience
We want to ensure our Analysts, Data Scientists, and Engineers can discover, understand, and publish high-quality data at scale. We have recently released a new data platform tool which enables simple, yet powerful creation of workflows via a declarative interface. You will help us ensure our users succeed in their work with effective and polished user experiences by developing our internal user-facing tooling and curating our documentation to the highest standards. And what’s best, you get to work closely with excited users to get continuous feedback about released features while supporting and onboarding them to new workflows.
Experimentation
We build and maintain our internal experimentation platform, Regatta, which supports A/B testing across the whole organization. We keep on expanding the capabilities of our platform, work in areas such as experiment distribution, analysis and on the front end used by our colleagues around the world. In this workstream you will be improving our current platform and work on our next generation experimentation experience.
Our tech stack
Our primary programming language of choice is Python. We deploy our systems in Kubernetes and AWS. We use Datadog for observability (logging and metrics). We have built our data warehouse on top of Snowflake and orchestrate our batch processes with Dagster. We are heavy users of Kafka and Kafka Connect. Our CI/CD pipelines rely on GitHub actions and Argo Workflows.
Our humble expectations
The vast majority of our services, applications and data pipelines are written in Python, so several years of having shipped production quality software in high throughput environments written in Python is essential. You should be very comfortable with typing, dependency management, unit-, integration- and end-to-end tests. If you believe that software isn’t just a program running on a machine, but the solution to someone’s problem, you’re in the right place.
Having previous experience in executing complex projects that touch multiple teams/stakeholders and run across a whole organization is a big plus. Good communication and collaboration skills are essential, and you shouldn’t shy away from problems, but be able to discuss them in a constructive way with your team and the Wolt Product team at large.
Familiarity with parts of our tech stack is definitely a plus, but we hire for attitude and ability to learn over knowing a specific technology that can be learned.
The tools we are building inside of the data platform ultimately serve our many stakeholders across the whole company, whether they are Analysts, Data Scientists or engineers in other teams that produce or consume data.
We want all of our users to love the tools we’re building and that is why we want you to focus on building intuitive and user friendly applications that enable everyone to use and work with data at Wolt
