✔ AI integration - experience integrating AI/LLM-powered features into production applications
✔ AI-assisted development - expert hands-on use of AI coding agents (Claude Code, Cursor, GitHub Copilot, or equivalent) for feature implementation, code review, debugging, refactoring, log/anomaly analysis, and production monitoring on a codebase of this scale
✔ Stripe payment integration
✔ Zoom or similar third-party API integration
✔ WordPress configuration, WPForms, and plugin maintenance
🎯 Responsibilities
✔ Implement features end-to-end: database to API to web UI to mobile screen

✔ Follow established coding standards without supervision
✔ Mentor junior developers through pair programming, code review, and structured growth feedback; set the engineering bar for the team
✔ Operationalize AI tooling across the codebase - coding agents, AI-assisted code review, log/anomaly analysis, and monitoring workflows independently of headcount so output scales
🔑 Ownership
This is a solo ownership role across the portal backend, web frontend, Flutter mobile apps, and WordPress public website. The candidate must treat the platform as their own product: proactively identifying issues, driving quality, and making decisions without waiting to be told. Full ownership is expected, from architecture decisions and code quality to deployments, monitoring, and production incidents. The candidate must be capable of handling all required work independently, end-to-end.
🤝 Engagement
✔ Full-time
✔ Fully remote; flexible schedule, with some availability during US business hours for meetings and collaboration
✔ Must sign a Non-Disclosure Agreement (NDA) prior to engagement
