We’re looking for a Backend Engineer to join the User Fraud studio’s Eraser squad. Our mission is simple, yet critical: make fraud a bad deal for bad actors. We protect creators, listeners, and the platform by raising attacker costs, lowering rewards, and shortening attack windows.
Eraser is a distributed team of backend and data engineers across Europe. We build and operate a mitigation platform that detects and responds to fraudulent and abusive behavior at scale. Our primary partners are fraud detection teams, and we also collaborate across multiple missions to help keep Spotify safe and trusted.
What You'll Do
-
Build, deploy, and operate backend (Java) services that mitigate fraud and abuse at scale
-
Collaborate closely with data engineers and work with Spotify’s data tech stack (Scala, Scio, Google Dataflow)
-
Evolve a distributed mitigation platform used by internal fraud detection teams
-
Design APIs, workflows, and system safeguards that protect legitimate users while reducing attacker impact
-
Improve system reliability, scalability, and observability using metrics, logs, and tracing
-
Partner with engineering teams across Europe and the US to integrate mitigation capabilities into broader systems
-
Contribute to strong engineering practices including code reviews, documentation, and incident learnings
Who You Are
-
You have 2+ years of experience designing, building, and operating backend services in production environments
-
You are experienced with APIs, distributed systems, and service-to-service communication
-
You have a strong understanding of data modeling and working with SQL and/or NoSQL databases
-
You care about system reliability, scalability, and operational excellence
-
You use metrics, logging, and monitoring to understand and improve system behavior
-
You communicate clearly and collaborate effectively with cross-functional teams
-
You’re curious about trust, safety, fraud, or adversarial problem spaces
Where You'll Be
-
This role is based in Stockholm or London
-
We offer you the flexibility to work where you work best! There will be some in person meetings, but still allows for flexibility to work from home.
