Senior Fullstack Java Engineer

Ready for a challenge?

Then Just Eat Takeaway.com might be the place for you. We’re a leading global online delivery platform, and our vision is to empower everyday convenience. 

Whether it’s a Friday-night feast, a post-gym poke bowl, or grabbing some groceries, our tech platform connects tens of millions of customers with hundreds of thousands of restaurant, grocery and convenience partners across the globe.

About this role

We are seeking a motivated and experienced engineer to join our team as we consolidate fragmented partner data into a global event-driven architecture. You'll help build tooling that empowers our operations team to manage restaurant partners, breaking down monolithic .NET applications into microservices using Java Spring Framework and Kubernetes. We are big on communication, collaboration and innersourcing across teams. 

* Please note that this position is located in Amsterdam (3 days a week from our Amsterdam office and 2 days working from home)

These are some of the key components to the position:  

• Design and implement high-performance, highly scalable, event-driven microservices for the partner domain.
• Partner with product teams to translate requirements into technical specifications, and align with cross-functional teams on API/Event contracts (e.g., OpenAPI, AsyncAPI, Confluent). 
• Write clean, efficient, and well-documented code while actively mentoring junior developers and driving code reviews to ensure system maintainability.
• Maintain, investigate, and document the revenue-driving legacy platform, acting quickly to debug and resolve any operational issues.
• Proactively explore emerging technologies and AI-driven tools to automate repetitive tasks, simplify full-stack complexities, and elevate overall code quality.
• Actively participate in team brainstorming sessions, communicate progress on complex features, and remain open to learning and innersourcing across new tech stacks.

What will you bring to the team? 

• In-depth knowledge of backend ecosystems (Java/Spring Framework OR C#/.Net) and design patterns, with expertise building event-driven microservices using message queues (e.g., Apache Kafka, AWS SNS/SQS). 
• Experience in full-stack development, including proficiency in modern front-end frameworks (such as Vue, React, etc.).
• Hands-on experience with AWS, CI/CD pipelines, Docker, Kubernetes, and Helm charts, alongside working knowledge of relational (MySQL) and NoSQL databases.
• Strong background in modern frontend and backend testing frameworks (e.g., JUnit, Testcontainers) and distributed tracing for microservices (e.g., OpenTelemetry, Datadog).
• Hands-on experience with Amazon Web Services (AWS), DevOps practices, CI/CD pipelines, Docker, Kubernetes, and Helm charts.
• Familiarity with PHP, broad exposure across multiple backend ecosystems (Java, .NET), and experience with cybersecurity practices.
