Medior Kotlin Engineer Retail Finance (Kotlin/Microservices/MongoDB)

Join Our Team as a Medior Kotlin Engineer in Retail Finance

How you can make a difference

We are looking for a proactive and motivated Medior Kotlin Engineer to join our team in the Retail Finance department. You’ll play an important role in a small, growing team that is responsible for migrating and modernizing our finance systems using Kotlin microservices. This is a unique opportunity to help shape the architecture and functionality of our next-generation finance platform, working closely with Product Owners and Engineering Managers.

Your new team and office

Our Finance teams are a special breed within Albert Heijn, working on complex and business-critical systems that handle the flow of money between Albert Heijn and its suppliers. We are currently a small team of three but rapidly growing as we take on a major new initiative: the Invoiceprep project. This project will span approximately two years and involves rethinking and rebuilding key finance functionalities, not just migrating them one-to-one from legacy systems.

We work hybrid from our office in Zaandam (right next to the train station) two days per week, with Tuesday as our main office day. The rest of the week you can work remotely. We value collaboration, knowledge sharing, and building a strong engineering community; you’ll have access to a network of over 150 engineers and regular opportunities to connect, learn, and have fun.

What You’ll Do.

• Design, develop, and maintain Kotlin microservices as part of our new finance architecture.
• Analyze existing legacy systems, identify which functionalities to migrate and how to improve them in the new platform.
• Take responsibility for your services, including deployment and lifecycle management (DevOps mindset).
• Work closely with Product Owners, other engineers, and stakeholders to deliver robust solutions.
• Help automate manual finance processes and contribute to a more efficient, scalable platform.
• Get involved in AI initiatives and DevAI offerings, with the freedom to experiment and innovate.
• Contribute to building an active engineering community within Albert Heijn.

What we offer.

At Albert Heijn, we aim to become a leading retail tech organization, and this is only possible if you join and grow along with us. As we work together, you can count on (based on 40 hours per week):

• An annual salary up to €77.5K including holiday allowance and a flexible bonus.
• Flexible working hours and 45 days of paid leave to enjoy your well-deserved holidays: 25.5 regular vacation days and 19.5 ADV days.
• A company laptop (Macbook or HP) and a phone (iPhone or Samsung Galaxy).
• 10% staff discount on groceries in all Albert Heijn stores, to a maximum of €300 per year and a free Mijn Albert Heijn Premium membership with many benefits.
• An excellent pension plan where we as an employer contribute 4.5 times more than you as an employee.
• Access to a challenging training curriculum – AH Tech Academy, including a Kotlin bootcamp.
• A travel allowance or a NS business card for traveling to and from Zaandam by train.
• Attractive discounts on various insurance policies.

What we’re looking for.

• 3+ years of experience as a backend engineer, with hands-on experience in Kotlin (or another JVM language such as Java or Scala). Kotlin experience is not required, but you should be willing to learn.
• Experience designing and building microservices architectures.
• Experience with relational and NoSQL databases (PostgreSQL and MongoDB).
• Experience with cloud platforms, preferably Azure.
• DevOps mindset: comfortable with CI/CD, deployments, and owning the full lifecycle of your services.
• Experience working in Agile product teams (2 week sprints).
• Security development experience or affinity with DevSecOps is a plus (e.g., OWASP).
• Strong analytical skills and ability to work on complex, business-critical systems.
• Willingness to work hybrid from our Zaandam office (at least 2 days per week, Tuesday is our main office day).
• Must already work and live in The Netherlands.
