• Innovate and Lead: Take ownership of your projects from concept to completion. You’ll have the autonomy to "build and run your own ship," contributing meaningful projects that shape our technological future.
• Translate business requirements for more complex technical cases and create complex tickets for the Salesforce team using your background in computer science/engineering
• Identify, scope and build key business opportunities for revenue growth by analyzing potential technical stack deployments (improved conversion, improved productivity/quality etc.) 
• Advocate for both internal and external customers through technology design of key processes, ensuring a seamless customer/agent journey
