•Collaborative Team – Join a global, skilled support team focused on learning and innovation.
Responsibilities
•Analyze and resolve complex software issues reported from production environments using C#, .NET, and associated debugging tools.
•Investigate and reproduce customer-reported defects in a controlled development environment, identify root causes, and implement code fixes.
•Work with the broader engineering team to deliver patches or hotfixes, ensuring quality and adherence to SLAs.
•Collaborate with customer-facing support teams to gather information, validate issues, and provide timely and detailed updates to stakeholders.
•Write or update code where necessary to improve system stability, performance, and maintainability.
•Review logs, performance metrics, and system behavior to proactively identify and address recurring problems.
•Contribute to knowledge-sharing initiatives by documenting known issues, workarounds, and permanent solutions in our internal and customer-facing portals.
