Datawarehouse Operator (Production)

#GreatWorkIsNotAMyth

Join RAINBOW, KBC’s next-generation group data warehouse platform serving multiple banking and insurance entities across the organization.  

RAINBOW is a large-scale, multi-tenant and event-driven data platform, where data flows are automatically triggered based on dependencies and conditions. With hundreds of contributors continuously developing and improving the platform, the environment is highly dynamic.  

As a Datawarehouse Operator for Production, you play a key role in ensuring that data is correctly processed, loaded, and delivered to our customers — both business users and development teams. Your work enables them to validate changes, build reports, and move forward with their initiatives.  

This is a hands-on operational role where execution, system understanding, and coordination come together.  

 

What You’ll Do:

 

• Execute and monitor data flows using our internal orchestration tool (OT)  
• Perform large-scale reloads after releases and targeted reloads after hotfixes or requests  
• Monitor executions via OT dashboards, UAC Workbench, and Teradata  
• Investigate failed or incomplete processes and raise issues to development teams  
• Monitor system performance, including query behavior in Teradata  
• Check and validate file deliveries on Linux systems  
• Coordinate with business and development teams on requests, priorities, and status updates  
• Ensure actions are safe by understanding dependencies and potential downstream impacts  
• Contribute to continuous improvement by documenting processes as the platform evolves  

 

👉 Your work directly supports our customers by delivering reliable, timely data and enabling reporting and validation  

 

How You Work: 

 

This role involves frequent interaction with tools and execution of flows—but it goes beyond simply running tasks.  

 

You will:  

 

• Think ahead before executing actions (“what could this impact?”)  
• Understand how flows, mappings, and datasets are connected  
• Decide when to proceed independently and when to escalate  
• Operate confidently in a fast-changing environment with varying workload intensity 
• Work closely with your teammates during work days in shifts – bussiness shifts (9:00 – 17:30) and rotating 1-2 afternoon shifts per week (12:30 - 21:00) 
• Provide occasional weekend shift to support the environment after infrastructure downtimes/patchings (once per 1-2 months) 

Your Profile

 

What Matters Most: 

 

• Clear communicator, able to work with both technical and business stakeholders  
• Strong analytical mindset and attention to detail  
• Ability to understand complex systems and dependencies  
• Structured and responsible way of working  
• Comfortable in a dynamic environment with changing priorities  

 

Technical Comfort: 

 

• Basic to good SQL knowledge (understanding queries and results)  
• Comfortable navigating Linux environments  
• Interest in data flows, systems, and how they interact 

 

Experience:  

 

• Experience in data operations, application support, or system operations is a plus  
• Familiarity with data warehousing or ETL concepts is helpful, but not required  

 

👉 You don’t need to be a DWH expert, but you do need to understand how actions impact the system  

 

Why This Role?  

 

• Work on a complex, large-scale data platform with a unique architecture  
• Be part of a high-impact operational team supporting a critical environment  
• Experience a dynamic workload with peaks around releases and quieter periods in between  
• Gain exposure to data, systems, and cross-team collaboration  
• Contribute to the growth of the platform by helping define and document new processes  

 

What Makes This Role Unique?  

 

• Not a typical data warehouse or IT operations role  
• Combines execution, analysis, and coordination  
• Requires understanding the system — not just operating it  
• Directly supports internal customers by delivering usable, reliable data and reports  

 

✅ Not just execution — understanding is key  

✅ Not just operations — you actively support business and development customers  

✅ A growing environment where you help shape how things work  

 

What you get: 

 

• Bonuses twice a year based on your performance . 
• Hybrid working mode with the possibility to work 50% from home. Our core working hours are from 9 am to 3 pm. 
• 28 days off per year to recharge. 
• Opportunities for business trips to Belgium (to our KBC Group headquarters). 
• Many benefits fully paid by us - Multisport card, learning courses, meal voucher card (170 CZK/day), Cafeteria benefit system, etc. 
• Referral bonuses. 
• Contribution to pension and life insurance, great deals on ČSOB products and much more.
