Senior Data Platform Engineer (dbt, Databricks, Apache Spark, Python)

Retail media is booming, and we’re building a cutting-edge platform to support all Ahold brands in Europe with a comprehensive retail media suite. Get to work in a high traffic environment on a SaaS solution that will be utilized by approximately 15 different brands across Europe.

You are a hands-on engineer who enjoys solving complex technical challenges and taking ownership of technical initiatives. You combine strong data engineering expertise with the ability to collaborate closely with peers, share knowledge, and help raise engineering quality across the team.

This is how you will reinvent food retail tech.

• Help establish and evolve engineering best practices in Databricks, Spark, dbt, Python, testing, observability, and CI/CD.
• Take a leading role in migrating existing data pipelines to a modern dbt-based platform, helping define standards, patterns, and ways of working for the wider team.
• Design and evolve scalable batch and streaming data platforms that process millions of records across multiple Ahold Delhaize brands.
• Support and coach fellow data engineers through knowledge sharing, code reviews, and shared engineering standards.
• Embed test automation in the way data engineers work, so it is part of delivery rather than a separate step.
• Guard the data models and the integrity of the data we hand to consumers.
• Build self-service models so other teams can work on the data platform themselves.
• Improve the reliability, scalability, performance, and cost-efficiency of our data platform and pipelines.
• Take ownership of data quality standards and operational excellence across our data products.
• Partner with platform engineers and architects to shape the future direction of our data platform.
• Lead technical discussions, evaluate architectural trade-offs, and help teams make sound engineering decisions.

Your new team and office.

In the ad-tech cluster, we are developing and implementing a retail media SaaS solution for all Ahold Delhaize brands in Europe. Retail media involves selling advertisement space on our digital touchpoints or in-store. Examples include:

• Promoting brands like Tony Chocoloney when customers search for chocolate on our website or app.
• Displaying advertisements on big screens inside and outside stores.
• Featuring supplier-branded banners on homepage or category pages.
• Exploring new territories as retail media is a rapidly growing field.

Our ad-tech cluster, part of the Customer Tech Platform, is responsible for a flexible, cost-efficient, high-end retail media suite with extensive functionality and a growing number of brand users.

We work in a highly collaborative and horizontally organized team without formal technical lead roles. We value engineers who take ownership, contribute proactively, and help shape technical decisions together.

We have a scale-up vibe with 5 teams and counting. A mature agile approach (no frameworks) helps you excel and showcase your skills. Our teams work in a hybrid way from both home and our office next to Zaandam station.

Making room for differences

We believe that everyone should feel comfortable being themselves and feel welcome and valued at work. We embrace different perspectives, experiences and backgrounds, and actively work to build engaged teams where everyone has the opportunity to contribute. We believe that different perspectives help us make better decisions and achieve better results together.

We look at the talents, knowledge, experience and personality you bring. Don’t meet every requirement but still see yourself in this role? We encourage you to apply. We welcome candidates with different backgrounds and experiences and are curious to hear what you can bring and what you would like to contribute.
