__Meet Your Team: Anti-Fraud Solutions__  

Our __Anti-Fraud Solutions__ team tackles one of adtech's biggest challenges: industry reports suggest 25% of global mobile ad spend is fraudulent. We've built sophisticated systems that actively prevent fraud from impacting our partners' business.   

At the core of our solution are custom-built mobile SDKs for Android and iOS, which analyze device integrity and detect modifications like Xposed frameworks, Magisk modules or jailbroken devices. Our distributed cloud infrastructure powered by SQS and Kafka processes billions of daily events to flag suspicious behaviors in real time, while Go-based microservices deliver millisecond-level responses using DynamoDB as our database.  

For developers interested in cheat prevention, this means working with cutting-edge tech to continuously outsmart even the most creative tactics.  

## What will you do

* Work on our iOS and Android SDKs that run on tens of millions of devices every day.
* Work closely with Backend and QA engineers to deliver necessary features
* Collaborate with other teams contributing to the same project to align on best practices and architecture
* Become a go-to expert for the team when it comes to platform-specific capabilities
* Investigate ways users can break or fool our fraud prevention methods in our SDKs

## Who you are

* You have a degree in computer science (or a similar field) and 4+ years of combined work experience in iOS and ideally Android development
* You have good knowledge of Swift and ideally Java/Kotlin
* You are proficient in both iOS and ideally Android -app, -operating systems, -and service life cycles
* You keep up to date with trends and changes in mobile development
* Optional: SDK development experience

## Fuel for the Journey: Benefits to Support Your Ambitions

Enjoy 30 vacation days, 3 weeks of remote work per year, and free access to an in-house gym with lots of different fitness classes and mental health support through our Employee Assistance Program (EAP).
