The Customer Success Team is responsible for delivering our product to our clients.

• Manage customer communications effectively, including conference calls and status updates to stakeholders.
• Clearly document and communicate issue root causes, impacts, and resolution steps to internal and external stakeholders.
• Escalate critical issues to the appropriate engineering teams and coordinate resolution efforts across multiple tiers of support.

• Contribute to the continuous improvement of support documentation, including the creation of internal and external knowledge base articles.
• Translate customer feedback into actionable engineering requirements and collaborate with Engineering and Customer Success teams to prioritize enhancements.
• Regularly interact with internal tools and bug-fixing processes using Shell scripting, SQL, and/or Python.
• After 3–6 months, participate in the on-call rotation for handling high-priority issues during weekends (approximately one weekend every three weeks), with additional compensation.
• Serve as a mentor and escalation point for L1 support staff, providing technical guidance and peer review for incident resolution.

You Have & You Know-how:

• Bachelor’s degree in Computer Science, Engineering, or a related technical field—or equivalent professional experience.
• 3–7 years of experience in a technical support, product support, or engineering role.
• Excellent written and verbal communication skills in English, with the ability to produce clear, professional customer-facing documentation (e.g., Root Cause Analysis reports).
