 * Strong with Kotlin and/or Java and frameworks like Ktor or Spring Boot

## Description

As a Senior Backend Engineer Utrecht, you play a key role in the evolution of the platform. You work with Kotlin, Ktor, Kafka, Kubernetes, GCP, BigQuery and PostgreSQL to design and build scalable backend services, real-time metering and data pipelines, and the APIs and billing primitives that sit at the heart of the product.

You are involved across the entire product lifecycle, from designing new services to building, testing and running them in production. This is genuine you build it you run it. The technical challenge is less about volume and more about precision: modeling pricing and billing logic that has to stay correct under growth, under concurrency, and under the messy reality of how customers actually use software. You make the foundational calls on data and cloud architecture and you own the consequences.

You collaborate closely with the product team to ship new monetization capabilities, including the infrastructure that lets AI products and agents be priced and billed per real usage. For an engineer who likes hard, conceptual problems with real-world stakes, there are few cleaner examples than money that has to be right.
