Job Description
Datawarehouse Operator (Production)
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. 

 

3 things you’ll love about KBC Global Services: 

 

#1 Work-life balance for real. Forget overtime and working while sleeping! We empower parents and young professionals juggling careers, studies and hobbies.  

#2 Stability. KBC Group includes the Czech ČSOB, the Belgian KBC, the Hungarian K&H, and more. We’ve been based in Brno since 2011 and offer you room for growth.

#3 International environment full of easy-going colleagues.
