## Description

We're looking for a Backend Engineer to join our Integrations Team, responsible for connecting Yuno's platform to PSPs, acquirers, payment gateways, fraud and 3DS providers worldwide.

As a Backend Engineer, you will build and maintain the integrations that are core to our product, working across countries, providers, and complex payment rails in a fast-moving, global environment.

Key responsibilities include:

* Building and evolving high-performance APIs and microservices in Go, designed for reliability, low latency, and scale.
* Taking end-to-end ownership of features and integrations , from discovery and design to production rollout and monitoring.
* Developing and extending integration frameworks that support payment processing, fraud detection, and authentication flows (e.g., 3DS) across multiple regions.

We're looking for someone with solid backend engineering experience building high-throughput, production-grade systems in Go, Java, or Kotlin, as well as a strong understanding of microservices and event-driven architectures, APIs, and integration patterns.

If you have experience in the payments industry or integrating with Payment Service Providers, and are comfortable working with AI-assisted development tools, we'd love to hear from you.

At Yuno, culture is a key part of how we operate and scale: we're a fast-paced and global team, operating in a dynamic, fully remote environment across multiple time zones. We offer competitive compensation, remote work, home office bonus, work equipment, stock options, health plan, and flexible days off.
