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 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. * Engineering: Design, develop, and maintain Kotlin microservices as part of our new finance architecture. * Migration: Analyze existing legacy systems, identify which functionalities to migrate and how to improve them in the new platform. * Ownership: Take end-to-end responsibility for your services, including deployment and lifecycle management (DevOps mindset). * Collaboration: Work closely with Product Owners, other engineers, and stakeholders to deliver robust solutions. * Automation: Help automate manual finance processes and contribute to a more efficient, scalable platform. * Innovation: Get involved in AI initiatives and DevAI offerings, with the freedom to experiment and innovate. * Community: Contribute to building an active engineering community within Albert Heijn. ## Related Videos - [Coffee With Developers Michael Koitz](https://www.wearedevelopers.com/videos/891-coffee-with-developers-michael-koitz) - [Leveraging Real time data in FSIs](https://www.wearedevelopers.com/videos/806-leveraging-real-time-data-in-fsis) - [Kotlin Multiplatform - True power of native code reuse](https://www.wearedevelopers.com/videos/4-kotlin-multiplatform-true-power-of-native-code-reuse) - [From DevOps to Scaled DevOps: How We’re Rebuilding Continuous Delivery as a Platform](https://www.wearedevelopers.com/videos/100018-from-devops-to-scaled-devops-how-we-re-rebuilding-continuous-delivery-as-a-platform) - [NoSQL Data Modeling for Front-end Developers](https://www.wearedevelopers.com/videos/297-nosql-data-modeling-for-front-end-developers) - [Why Kotlin is the better Java and how you can start using it](https://www.wearedevelopers.com/videos/661-why-kotlin-is-the-better-java-and-how-you-can-start-using-it) ## Related Articles - [Best Companies in the Netherlands: Top 25 Companies in 2023 ](https://www.wearedevelopers.com/magazine/193-best-companies-in-the-netherlands-top-25-companies-in-2023) - [Software Developer Salary in The Netherlands [2023]](https://www.wearedevelopers.com/magazine/217-software-developer-salary-in-the-netherlands-2023) - [How to Find Tech Jobs in Amsterdam](https://www.wearedevelopers.com/magazine/279-how-to-find-tech-jobs-in-amsterdam) - [How to land a developer job in Amsterdam](https://www.wearedevelopers.com/magazine/36-how-to-land-a-developer-job-in-amsterdam) - [The Netherlands – Europe’s powerhouse for software development?](https://www.wearedevelopers.com/magazine/31-the-netherlands-europe-s-powerhouse-for-software-development) - [The Biggest German Tech Companies](https://www.wearedevelopers.com/magazine/424-the-biggest-german-tech-companies)
