Jobs at Djinni

Ever wanted to grow as an engineer on a real product - not pet projects or short-term tasks, but a system that real businesses rely on every day?
Where you don’t just “code features”, but gradually learn how large, mission-critical systems are built, maintained, and modernized?
Where you can gain hands-on experience with legacy systems and be part of a long-term transition to modern .NET architecture?

If you’re a Junior/Middle- level C# developer with around 2 years of experience and curiosity about real-world systems - this role is a great growth opportunity.

Bonus if you have:

• Experience with adtech or real-time bidding
• Agile / Scrum experience
• Knowledge of high-availability infrastructure (ElasticSearch, Kafka, ClickHouse)
• Airflow expertise

About the Data Science Team:

We’re 17 ML engineers, data scientists, and data engineers, distributed across London, Poland, and Ukraine — acting as one team, not a satellite office.
