About the job

• Massive Scale: Design, build, and optimize systems that handle thousands of requests per minute. This is high-availability, high-performance engineering in practice.

• Modern Tech Stack: Work with a world-class, cloud-native environment. Our core technologies include Kotlin, Spring, Kafka, and Kubernetes. We're not shy when it comes to ML too :)

• True Ownership & Autonomy: We live by a "you build it, you run it" philosophy. You'll join an agile, autonomous team with full ownership of your microservices, from design to deployment.

• Complex Challenges: From distributed systems and data streaming to algorithmic optimization, you'll tackle the complex backend problems that power a massive, real-time marketplace.

• End-to-End ML Systems: Bridge the gap between big data and real-time product impact. You'll build the infrastructure using BigQuery and Apache Spark for offline data processing. You'll integrate these components with our microservices architecture to create the sophisticated advertising system that powers a personalized user experience.

What's in it for you:

• Well-located offices (with e.g. fully equipped kitchens, bicycle parking, terraces full of greenery) and excellent work tools (e.g., raised desks, ergonomic chairs, interactive conference rooms).

• A 16" or 14" MacBook Pro or corresponding Dell with Windows (if you don't like Macs) and all the necessary accessories.

• A wide selection of fringe benefits in a cafeteria plan - you choose what you like (e.g., medical, sports or lunch packages, insurance, purchase vouchers).

• English classes that we pay for related to the specific nature of your job.

• A training budget, inter-team tourism (see more here), hackathons, and an internal learning platform where you will find multiple trainings.

• An additional day off for volunteering, which you can use alone, with a team, or with a larger group of people connected by a common goal.
