Application Support Engineer (supporting US and Asia-Pacific markets)

You will be part of a team supporting clients across different time zones - including the US and Asia-Pacific. This is a great opportunity for someone who enjoys technical problem-solving, working directly with international clients and wants to develop their career in a highly specialised technology environment. Working hours- supporting US and Asia-Pacific markets This role is designed around supporting clients in different global markets. During the onboarding and training period, you will initially work primarily during US business hours, working closely with the US-based team and clients, learning the systems and processes. Once you are fully trained and able to work independently, you will move to a rotational shift schedule covering US and Asia-Pacific clients: Second/ US shift: 16:00-00:30 - supporting US business hours Third/ AP shift: 00:00-08:30 - supporting Asia-Pacific hours You should therefore be comfortable working both afternoon/evening and night shifts as part of a planned rotation. These are regular full working shifts, not on-call or standby shifts. You will be responsible for providing full technical support throughout your scheduled working hours. Each 8.5-hour shift includes a 30-minute paid lunch break, meaning 8 hours of actual working time. There is a short overlap between the shifts to allow the team to hand over ongoing issues and important information. Please note: the shift schedule and rotation model are currently planned and may be adjusted before final implementation. Why is this role different? This is much more than a traditional Application Support position. You will not simply receive tickets, resolve them and move on. You will become an important part of a small, highly specialised international team. Your responsibilities will combine: technical troubleshooting direct client communication application support client onboarding project coordination production issue investigation process and efficiency improvements Because the team is relatively small, your work will be highly visible and your contribution will have a real impact on the company and its clients.
