About the job

We’re looking for a Data Engineer to join our Commercial Business Unit and support the Opera Ads product. This is a brand-new role in a well-established data science team, offering the unique opportunity to shape a new initiative from day one. You’ll work closely with our ADX Engineering Team to ensure data pipelines run smoothly.

You’ll dive into a large-scale advertising ecosystem and collaborate with global teams, including potential travel to China for in-person knowledge sharing. If you enjoy working with open-source tools, optimizing infrastructure, and being part of impactful projects, this is the role for you.


Role & Responsibilities:

  • Ensure smooth execution of offline data jobs and troubleshoot anomalies

  • Contribute to developing scripts for data cleaning, export, backups, and reports

  • Support internal stakeholders (AM/Operations) with data-related requests


Job Requirements:

  • Proven experience as a Data Engineer or similar role

  • Strong command of Python, Bash, SQL, and Hadoop

  • Experience with at least three of the following: Hive, Spark, Flink, Kafka, Flume

  • Experience with workflow management tools

  • Excellent communication skills, openness, and a proactive mindset


An Ideal Candidate’s Profile:

  • Familiarity with Java/Scala or ClickHouse is a plus

  • You are open-minded, culturally aware, and not afraid to ask questions

  • You thrive in dynamic environments and enjoy proposing improvements


What’s on Offer:

  • Be part of an international team with occasional business trips to China

  • Learn from a complex, large-scale advertising ecosystem

  • Use only open-source technologies—skills that stay relevant across the industry

  • Play a key role in a new project, with high visibility and long-term impact

  • Flat organizational structure and short decision-making processes

  • Continuous professional development in a fast-paced, innovative environment

  • A diverse and inclusive workplace where your voice matters
