We are hiring an experienced application developer for one of Lago's partner clients. You will architect, build, and deploy a custom HighLevel Marketplace App that syncs golfer, membership, booking, and financial data across their entire network. This is a hands-on role working with leadership, engineering, and operations to turn disconnected systems into a clean and automated platform.
What You Will Build
You will architect, develop, and deploy a custom HighLevel marketplace app that integrates:
- Sync Core Systems With HighLevel

- Sync Membership Data
- Pull and map active memberships, levels, statuses, custom fields, history, and recurring revenue data for every golfer.
- Integrate Full Swing Data
- Authenticate with Full Swing, pull golfer profiles and performance data, and map everything into the correct contact or custom fields in HighLevel.
- Sync Revenue and Financial Metrics
- Pull and push revenue, transactions, upsells, promo use, and any KPI data needed for dashboards and automation.
- Sync Tee Times and Bookings
- Sync all bookings, cancellations, reschedules, confirmations, and attendance between the booking engine and HighLevel in real time.
- Sync Forms and Lead Activity
- Pull form submissions, create or update contacts, and map fields and tags into the correct sub-account.
- Support a Multi Location Franchise Model
- Assign data to the right franchise sub-account, keep data separated, and support proper versioning for a Marketplace app.
Responsibilities
- Architect and maintain the data model for all integrations
- Build backend logic connecting HighLevel, Back Nine, and Full Swing APIs
- Implement real-time sync, error handling, and data integrity safeguards
- Develop scalable provisioning for new franchises
- Document the full integration for deployment and future development
- Communicate progress clearly with all stakeholders
