You will work closely with Cresta product and engineering teams to analyze technical tradeoffs, own customer-facing deliverables, and constantly identify opportunities for product improvement. The role demands that you demonstrate engineering best practices in all deliverables and uphold the same high standards across the team. You will enhance compliance and QA processes by building rules-based screen capturing systems that provide detailed information about agent desktop activity. Additionally, you will support PII/PCI redaction through trigger conditions based on detailed desktop and browser activity.
