Backend Developer - Host Experience (all genders)

Munich, Germany

Share job

Holidu is one of the world’s fastest-growing vacation rental technology companies. Our mission is to make booking and hosting holiday homes free of doubt and full of joy, by helping hosts generate more bookings with less work and helping guests find a holiday home they truly enjoy. Our team of 700 colleagues from 60+ nations shares a passion for tech, an ambition for constant improvement, and a relentless drive to bring the best experience to more than 40k vacation rental hosts and 4 million annual guests.

Your future team

Join our Host Experience department as a Backend Developer and become part of the team that brings new vacation rental properties to life on Holidu. You'll be working at the heart of our property acquisition engine — where we take hosts from their very first sign-up all the way to their first booking, making that journey as fast and seamless as possible.

This team sits at a uniquely strategic intersection of product and growth. You will build and optimize the systems that every new host flows through: from onboarding and listing creation, to property configuration, content quality, and referral programs. The work demands reliability and attention to detail — because the time between a host signing up and welcoming their first guest, and how well their property performs from day one, is directly shaped by the quality of what you build.

Our Tech Stack

Backend written in Kotlin and Java 21+ (with Spring Boot), with Gradle.
Deployed as microservices on AWS-hosted Kubernetes cluster (EKS).
Internal and external web applications written with ReactJS.
Event-driven communication between services through EventBridge with SQS / ActiveMQ.
Usage of a diverse set of technologies depending on the use case, such as PostgreSQL, S3, Valkey, ElasticSearch, GraphQL, and many more.
Monitoring with OpenTelemetry, Grafana, Prometheus, ELK, APM, and CloudWatch.

Your role in this journey

Design, build, evolve, and maintain our services, creating a great user experience for our hosts.
Build a strong understanding of the product, use it to drive initiatives end-to-end, and contribute to shaping the team's direction as you grow.
Work AI-first: use AI to accelerate not just coding, but data exploration, codebase understanding, technical design, and decision-making — and continuously sharpen how you use these tools.
Ensure our applications are highly scalable, capable of handling tens of thousands of properties and millions of bookings.
Work with data persistence - whether in PostgreSQL, Redis, S3, or new state-of-the-art technologies you help us evaluate.
Ship to production daily — deploying to our AWS Kubernetes cluster is part of the routine, not a special occasion.
Contribute to the reliability of your services — learn to set up monitoring and participate in incident resolution so your team can move fast with confidence.
Collaborate in a supportive, cross-functional team that values knowledge sharing and improving together.
Apply engineering best practices, and stay curious by experimenting with new technologies.

Your backpack is filled with

A passion for great user experience and drive to deliver world-class products.
Early experience delivering product impact through engineering — you've shipped things that real users depend on.
Experience with Java or Kotlin with Spring is a plus
Experience with relational databases and deploying apps in cloud environments. NoSQL experience is a plus.
Familiarity with various API types and integration best practices.
Strong problem-solving skills and a team-oriented mindset.
