• Work with tools such as SQL/ Datadog / Databricks, Jira, Zendesk/HubSpot, and related platforms.


• Determine whether an issue is related to configuration, data, user behavior, product behavior, or a potential software defect.


• Create technically complete escalations for Engineering/R&D.


• Provide clear reproduction steps, evidence, logs, queries, screenshots, and other relevant technical information.


• Coordinate with Engineering through investigation and resolution.


• Provide timely updates to customers and internal stakeholders based on issue severity.


• Work within defined high, medium, and low severity investigation and escalation timelines.


• Support Tier 1 team members with complex technical troubleshooting.


• Identify recurring issues and contribute to root-cause analysis.


• Create and maintain troubleshooting guides and internal technical documentation.


• Identify opportunities to automate repetitive support activities and responses.


• Participate in customer calls when deeper technical troubleshooting is required.

• API troubleshooting


• Practical SQL experience, including:


• SELECT


• JOINs


• GROUP BY


• AI Integration


• Filtering


• Aggregations


• Data investigation


• Experience using browser Developer Tools and network inspection.

• Experience with Jira or similar issue-management tools.


• Experience with Zendesk, HubSpot, or similar support platforms is preferred.

• Ability to explain technical issues clearly to both technical and non-technical stakeholders.


• Strong ownership of technical issues from investigation through escalation and resolution.
