• Optimize and refactor existing code to improve performance and reliability

What This Role Requires:

• High attention to details to ensure consistent delivery of stated requirements with accuracy and within expected timelines
• Ownership of your work and your projects, establishing deadlines, and communicating progress proactively, while working on multiple projects

• Critical thinking, problem-solving, and resolution
• Being a strong team player who works well with a wide range of people from different parts of the business, customer base, and WeVend partnerships
