We are is seeking a Principal Frontend Engineer to lead modernization and architecture improvements for their Point of Sale (POS) systems.

The role requires improving code quality, consistency, structure, and reducing duplication. On the backend, the system uses message queues and asynchronous patterns to handle concurrency and real-world chaos.

Key Responsibilities:

• Provide technical leadership in a messy, legacy frontend environment
• Standardize frontend codebases across checkout experiences
• Mentor engineers and improve team culture and engineering practices
• Modernize React/Angular/Vue-based frontend architecture
• Ensure POS systems handle real-time, concurrent inputs reliably
• Improve code quality, platform structure, and scalability

Qualifications:

• Senior engineering leader, not just a hands-on coder
• Proficiency in React, Angular, or Vue (modern versions)
• Experience with real-time and concurrent systems
• Ability to lead platform modernization and architectural improvements
• Strong problem-solving and mentorship skills
• Willingness to work onsite 5 days/week in Blue Ash, OH

This is a unique opportunity for a highly technical, leadership-focused engineer to shape POS frontend systems, set standards, and drive long-term modernization.
