__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:

* Contribute to the development of our backend written 99% in Go and maintain our microservice architecture used to communicate with our frontend (an Android SDK and a React-based JavaScript application). To do this, you’ll use event buses like Kafka, SQS/SNS, and Kinesis in order to have reliable asynchronous microservice communication.
* Work in a community of developers with whom you’ll share knowledge and contribute to peer code reviews.
* Work with modern databases such as Dynamodb and Scylla, where you’ll optimize queries and the way we query data to deliver few-millisecond response times.
* Collaborate with our Data Science and BI team to figure out where and how cheaters could exploit our system and implement mitigations for it.
* Work on a sophisticated VPN detection that can detect even residential proxies.
* Be responsible for collecting the billions of daily API events and aggregating them in our Kafka and Kinesis streams with the goal of querying them from the data lake in a matter of seconds.
* Be part of an international English-speaking team dedicated to scaling our adtech platform beyond our hundreds of millions of monthly active users.

## Who You Are:

* You have worked in software development for 4+ years.
* You have gained profound experience building web applications in Go for at least 3 years.
* You have knowledge of databases and a basic understanding of Regular Expressions, HTTP protocol, and Encoding.
* You have very good knowledge about TCP networking and understand how routing works on the internet.
* You are open to relocating to Hamburg, Germany
* Plus: You have experience working with infrastructure as code (Terraform), Docker, and other container orchestration platforms (e.g. kubernetes or ECS).

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

* __Invest in Your Future:__ Regular feedback and our development program support your growth, helping you expand your skillset and achieve your career goals.
* __Easy Arrival to adjoe:__ From signing to settling in Hamburg, we’ve got you covered. Need a visa? No problem. Ready to build your new life and career at adjoe in Hamburg? We support every ambition—from learning German to a relocation bonus that helps you settle in and make Hamburg feel like home.
* __Live Your Best Life, at Work and Beyond:__ We work in a hybrid setup with 3 core office days, plus flexible working hours. 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).
* Thrive Where You Work: Enjoy the Alster lake view from our central office with top-notch equipment, fun open spaces, and a large variety of snacks and drinks.
* __Join the Community!__ Participate in regular team and company events, including hackathons and social gatherings. We work together, and we celebrate together, too.
