Hamburg, Hamburg, Deutschland adjoe GmbH Vollzeit

We are adjoe GmbH, a leading mobile ad platform developing cutting-edge advertising and monetization solutions that take our app partners' business to the next level. As part of the applike group ecosystem, we offer an advanced tech stack, powerful financial backing from Bertelsmann, and a highly motivated workforce.

Meet Your Team: Advertising Dashboard

The Demand Solutions department builds core technologies to help mobile publishers acquire users for their apps and games. We're proud that our software – developed 100% in-house – manages advertisements for over 200 million daily mobile users. Our team provides statistical data via a dashboard to supply valuable insights to our partners. For this, we leverage machine learning models built by our BI analysts and data scientists.

Job Responsibilities:
  1. Contribute to the development of our backend written +99% in Go and maintain our microservice architecture used to communicate with our frontend (based on TypeScript React). You'll use event buses like Kafka and SQS/SNS for reliable asynchronous microservice communication.
  2. Work in a community of developers who share knowledge and contribute to peer code reviews.
  3. Optimize queries and data retrieval to deliver few-millisecond response times using modern columnar databases like Druid and MySQL.
  4. Support partners by providing them with raw or aggregated data based on their business needs, promoting data transparency and well-documented open APIs.
  5. Be responsible for collecting billions of daily API events and aggregating them in our Kafka and Kinesis streams for querying from the data lake in seconds.

As part of an international English-speaking team, you will be dedicated to scaling our adtech platform beyond hundreds of millions of monthly active users.

About You:
  1. You have worked in software development for 8+ years.
  2. You have gained profound experience with building web applications in Go for at least 5 years.
  3. You have worked with at least one columnar database (Druid, ClickHouse, Snowflake, Vertica, ...) and know how to analyze and optimize queries for it.
  4. You know how to profile a Go application and figure out bottlenecks, having used this to optimize application code.
  5. You have worked on a large Go application with considerable traffic (>100e6 requests per day).
  6. You are open to relocating to Hamburg, Germany.
  7. Plus: You have experience working with infrastructure as code (Terraform), Docker, and serverless infrastructure.
What We Offer:
  • Salary: €90,000 - €110,000 per year, depending on experience.
  • A comprehensive relocation package, including visa & legal support, relocation bonus, reimbursement of German Classes costs, and more.
  • A flexible work-life balance, with 2 remote days per week, 30 vacation days, and 3 weeks per year of remote work.
  • A state-of-the-art office in the city center, featuring a dog-friendly environment and free breakfast and pastries every Monday.
  • Ongoing education and professional development opportunities directly connected to your career goals.
  • A wealth-building program, offering virtual stock options for all regular employees.
  • A variety of health and wellness programs, including an in-house gym, personal trainer, yoga classes, and access to an Employee Assistance Program.
