POS Operations Specialist

Responsibilities

We are looking for a POS Operations Support Specialist to support the reliable operation of point-of-sale systems across OBI's international retail markets. You will help maintain POS system records, investigate technical and transaction-related issues, and support fiscalization and payment dispute processes.

Working closely with internal support teams, field service technicians, and external partners, you will contribute to the stability, compliance, and operational efficiency of OBI's checkout infrastructure. This role combines technical troubleshooting, database investigation, and structured operational support, making it a good opportunity for someone with basic Linux and SQL knowledge who wants to develop their expertise in retail IT.

Your key responsibilities will include

• Support the administration of POS systems, including their registration, decommissioning, and replacement, with a particular focus on the Austrian market.
• Maintain accurate POS records in the EFSTA fiscalization platform, ensuring that system information and installation histories are up to date.
• Assist field service technicians with POS decommissioning by accessing Linux-based systems via SSH, navigating local web interfaces, and coordinating required technical activities.
• Monitor and investigate inactive or potentially non-compliant POS systems, working with external fiscalization partners to resolve issues, particularly in the Slovenian market.
• Analyze electronic journals, archived receipts, and store databases using SQL to verify transaction processing and fiscalization status.
• Investigate payment disputes and chargebacks through Adyen, collecting transaction records and supporting documentation, and verifying returns and refunds.
• Maintain operational documentation, fiscalization protocols, and installation records while coordinating with internal teams and external service providers.

Benefits

• Motivizer Benefits Platform to choose and manage all your benefits in one place. You receive a budget (550 PLN monthly). You can choose medical care package, meal tickets, sports cards (we have Multisport and on preferential terms, we have membership cards to one of the most popular Gyms), cinema tickets, shop vouchers, discounts and many more.
• Language Courses - you'll have access to a multi-language learning platform enabling you to practice your language skills and learn new ones!
• Regular and systematic further training opportunities - both internally and from external providers. We support your ongoing learning and development.
• Cooperation within an internal community is our everyday reality. We have networking events, coding challenges, and company parties for different occasions.

Qualifications

• Completed university degree in Computer Science or a comparable technical field.
• Previous professional experience in IT Support, Application Support, IT Operations, or Retail IT, preferably involving business-critical applications or production systems.
• Basic practical knowledge of Linux, including SSH access, port forwarding, file system navigation, and log analysis.
• Basic SQL skills and the ability to query databases and investigate transaction-related data.
• Understanding of technical troubleshooting processes, with the ability to follow procedures, analyze issues, and work systematically with production systems.
• Strong attention to detail and organizational skills, particularly when handling transaction records, fiscalization documentation, and payment disputes.
