• 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.

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.
• Strong communication skills in English and Polish, with readiness to work in a hybrid model in Katowice.

Nice to have

• Experience with POS systems, retail technology, or point-of-sale application support.
• Familiarity with EFSTA or other fiscalization platforms.
• Experience with Adyen or other payment service providers.
• Understanding of transaction processing, electronic journals, refunds, and chargeback workflows.
