Role Overview.

As a P3 Full Stack Software Engineer, you are a solid, dependable individual contributor who can independently deliver well-scoped features across the frontend and backend.

• Build and consume RESTful APIs and integrate with internal systems.
• Write clean, maintainable, and testable code aligned with Toast engineering standards.
• Participate actively in code reviews—both receiving and providing constructive feedback.
• Troubleshoot production and non-production issues within owned areas and contribute to root-cause analysis.
• Use Gradle or Maven, Git, and standard development workflows effectively.
• Apply AI-assisted development tools (e.g., Claude Code, Cursor, Devin) to improve development speed and quality.
• Support team delivery during critical phases when needed, including production issues and urgent fixes.

P3 Competency Expectations at Toast:

• Consistently delivers on commitments with predictable cycle time for scoped work.
• Demonstrates ownership of components or features but does not yet own large systems end-to-end.
