Senior Software Engineer

We’re looking for a hands-on Senior Software Engineer to join our Data Engineering team, specifically the DataOps squad. We're the team behind the pipelines that move and transform 99% of the company’s data.

If you enjoy building real-time and batch data systems, working with AWS, and keeping things running smoothly under the hood, this is for you.

What You’ll Actually Do Here

• Design, build, and maintain scalable and reliable data pipelines using tools like AWS Kinesis, DynamoDB, S3, Elasticsearch, and RabbitMQ
• Own the technical health and architecture of our data platform — from ETL processes to observability and performance
• Collaborate with other teams to understand data needs, identify bottlenecks, and deliver solutions
• Break down large technical tasks into actionable work for the team
• Suggest and help implement practical improvements to the stack and processes
• Help drive technical decisions and share knowledge within the team
• Occasionally act as a translator between engineering and product when it comes to data questions

What You'll Bring To Us

• Solid experience with Java (we use Java 21) and the Spring framework
• Strong grasp of distributed systems and how to keep them reliable
• Familiarity with NoSQL databases (e.g., DynamoDB), Elasticsearch, and data streaming
• A proactive mindset — you like solving problems, not waiting for someone else to do it
• Good communication skills, especially when explaining technical topics simply
• Comfort navigating AWS and modern data infrastructure (bonus if you’ve used Spark, Flink, or PySpark)
• Willingness to learn and experiment with new tools
• Already based in the Czech Republic and legally able to work here

Tech Stack Snapshot

• Languages & Frameworks: Java 21, Spring
• Data: DynamoDB, Elasticsearch, S3
• Streaming: AWS Kinesis, RabbitMQ
• Infrastructure: Docker, AWS, LocalStack
• Bonus Points: PySpark, Apache Spark, Apache Flink, CI/CD, RDBMS, integration testing

We’re looking for candidates already living in the Czech Republic with a valid work permit, as we’re unable to provide relocation support for this role.

What We Offer

• Unlimited Vacation, 3 sick days, home office
• Flexible working hours
• Internal tech talks, Udemy courses, and workshops
• Maternity and Parental Benefit
• Meetups & conferences
• Multisport card
• A team of smart, no-nonsense people who actually care about doing good work
• Agile and open-minded culture, with high levels of trust and flexibility 
• Possibility to learn new and cutting-edge technologies in an environment that encourages new ideas
• Possibility to work from offices in Prague (Karlin), Brno (Impact Hub), Pilsen (Roudná)
• Chance to compete in a ping-pong tournament or to enjoy table football, Playstation, ergonomic exercise, or run with colleagues and grilling if you're into that
• There’s more as well! Speak with us to find out all the details!
