Job description

How do you make our customers happy?

All our colleagues want to use data to improve the quality of their decisions to positively impact our customers’ lives and partners’ businesses. We are building a self-service data architecture that empowers teams to satisfy their data needs autonomously — and now we are taking the next step: making our Data Platform intelligently proactive, delivering personalized insights to the people who need them, when they need them.

How do you make our customers happy?

In this context, the Data, Analytics & AI department is evolving bol’s Data Platform from infrastructure into an intelligent analytics layer. We serve the entire bol organization, where every department or domain has its own challenge. How do you move beyond dashboards toward agentic analytics, systems that surface relevant insights, answer questions conversationally, and act on behalf of users? How do you do that in a decentralized setup, with enthusiastic data engineers and analysts who want state‑of‑the‑art tools but also have to comply with rules & regulations? How do we get qualitative insights on the effectiveness of our product teams to decision makers, without them having to go looking?

In short:

You will help build a scalable, governed, and AI‑ready data platform that enables hundreds of teams and analysts to create value from data—while shaping the future of analytics at bol.

The biggest challenge

Our Data department is taking the Data Platform to the next level. A huge challenge because we serve the entire organization, and every department presents unique data challenges.

How can we build an analytics experience that feels personal — where insights find the user, not the other way around?

How can we empower enthusiastic analysts who want to push agentic and conversational tools to their full potential while still complying with all applicable rules and regulations?

How can we inspire engineers to make data easily accessible, semantically rich, and ready for intelligent consumption?

And what options should we explore to monetize our data and intelligence capabilities internally and externally?

What you will do as Software Engineer - Data Platform

Platform Development and Maintenance

Define, build and maintain the internal data platform to support data ingestion and data quality.
Enable self‑serve capabilities of the data platform
Ensure the platform’s cost efficiency, performance, and security.

Where you'll be working

The Data Engineering Platform builds our internal data platform foundation and enables it to scale. As a platform team it builds components to enable engineers work with data efficiently in a standardized way. The Data, Analytics & AI department foresees opportunities to establish a platform where data can be easily found, is reliable and compliant and of high quality, while ensuring data availability.

This team is part of Data Analytics & AI department, together with other IT teams, in a highly multicultural environment, with engineers from all over the world. All teams work closely with product managers, lead engineers and tech architects.

Team’s vision

Team’s vision is to enable data and AI use cases for users to independently build and operate data products by providing standardized, opinionated tooling, clear abstractions, and guardrails for security, compliance, and cost. Some parts are already in place and it is expected from the new team member to help us figure out which components need to be added to build a reliable set of tools to serve data. This role is made for a highly driven Engineer with strong Kotlin and Java skills and thrives in the face of change and uncertainty.

The role

The Software Engineer will play a critical role in designing, developing, and maintaining robust data infrastructure to support a scalable and efficient internal data platform. You will design and deliver core data platform capabilities such as standardized ingestion frameworks, data quality and observability tooling, metadata and governance services, and enable data to be consumed by both analytical workloads and AI‑driven applications.

The software engineer that the team needs is a software engineer who is eager to understand the complexity of creating tools used by hundreds of teams.

You combine your deep technical expertise with the ability to make complex concepts accessible to a diverse audience.

Something for you?

You have an innovative mindset: Constantly seek opportunities to improve yourself, systems and processes and want to apply it (via AI)
You communicate like a pro: You are not afraid to be open, ask questions and share your ideas and feedback
You are a team player: You thrive in a collaborative environment, value knowledge sharing and supporting each other in the team

Nothing for you?

You don’t like using AI: You prefer to focus only on coding and using AI for development is not your style
You want to be led by hand: Autonomy and ownership are not for you
You like to work by yourself: Transparency and collaboration don’t come naturally to you

We take pride in our B Corp certification and strive for continuous improvement every day. Our annual bonus is tied to sustainability goals, and we are committed to equality and equal opportunities for all.
