Python Developer (Data product)

Join Albert Heijn’s Data Differentiation Platform (DDP) as a Python Developer

Join Albert Heijn’s Data Differentiation Platform (DDP) and help shape Thor, our cloud data platform powering advanced analytics across all Ahold brands. In this role, you’ll work on building secure, scalable, and auditable access to large datasets, enabling our teams to turn data into actionable insights. If you’re passionate about software engineering, enjoy solving complex challenges, and want to make a tangible impact on the future of food retail, this role is for you.

Our Data Platform.
Our department, the Data Differentiation Platform (DDP), operates Thor, a full-fledged cloud data platform built around an ELT datastore and powered by Databricks and Azure. The platform already enables secure and auditable access to large datasets across multiple environments.

Thor’s aim is the decentralization of operational loads, following the principles of the Data Mesh architecture. Our ambition is to make Thor a reusable platform for all 16 Ahold brands, scaling its impact even further.

Offering the business stakeholders tools to onboard and use data is only one side of the analytics platform work: users need to be able to find the right sources, access them, understand them, and trust them, to ultimately use them for their work and create tangible business value. This is where the team we are recruiting for comes into play.

Your new team and office.
You will become part of a collaborative team that owns, designs, builds, and maintains the application managing user access on Thor. This product combines components ranging from internally faced APIs (Python, FastAPI) to infrastructure management (Azure, Databricks, Terraform/Terragrunt). We are looking for engineers with a strong software engineering background who are willing to not only write code but also design scalable, secure systems that integrate seamlessly with the wider data platform ecosystem.

You will work on inspiring projects that accelerate our transition into a hybrid Food & Tech company. At Albert Heijn, we leverage data and technology to make food shopping easier, healthier, and more accessible for everyone. You will team up with talented peers across the data, digital, and tech domains—a community of diverse individuals united by the goal of creating digital solutions that make (online) shopping simpler and more inspiring.

Our teams work in a hybrid way, from home and in our office next to Zaandam train station. We also invest heavily in your development, ensuring your career grows alongside our platforms.

This is how you will reinvent food retail.

• Designing and implementing new API endpoints to support internal tools and self-service user flows
• Building approval workflows to enable secure, auditable, and scalable access to datasets
• Extending access control beyond Databricks to other cloud-native and enterprise data assets
• Continuously improving observability mechanisms
• Troubleshooting access issues and supporting users across multiple environments

We think it’s important to be part of a high-belonging team; a team where you can be yourself and feel safe, accepted and appreciated. For this job we are preferably looking for someone who brings diversity in our team, in the widest possible sense. Someone who is a great addition to our team by bringing other ideas to the table. So don’t check all the boxes? Don’t worry, we probably don’t either 😉. Don’t hesitate to apply if you think you are up for the challenge, we’re happy to have a look at your resume!

What we’re looking for.

• 3–5 years of relevant experience in software development
• Hands-on Python experience with strong programming skills (OOP)
• Comfortable with async/await and robust error handling (e.g. 4xx vs 5xx)
• Experience designing and building APIs with FastAPI & Pydantic (model validation, response models)
• Writes both unit and integration tests to ensure code quality and system reliability
• Solid engineering practices: git, CI/CD, containerization (Docker)
• Familiarity with Azure cloud infrastructure and Infrastructure as Code (Terraform)
• Hands-on experience in data-heavy environments (bonus: ingestion/streaming patterns)
• Dedication to high-quality software engineering practices and system design
• Collaborative mindset (pair/mob programming, open feedback culture)
• Curious, proactive, fast learner who quickly pick-ups new areas

Nice to have:

• Knowledge of Databricks or Unity Catalog
• An interest in data-related technologies and business applications
• Understands and applies domain modeling in a backend context
• Familiarity with OAuth2-based authorization flows
• Striving for pragmatism: we always want to try new things, but with an eye on sustainability, in terms of shipping times, maintenance, security, and cloud costs

What we offer.
At Albert Heijn we aim to grow, and this is only possible if you grow along with us. As we work together to build our brand and your career, you can count on (based on 40 hours per week):

• An annual salary up to 75k including holiday allowance and a flexible bonus. Depending on your experience
