Czech Republic Prague Pilsen Brno Emplifi Full time 40,000 - 80,000 per year

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
