Facebook Meta API Architect Developer

Senior Facebook API Architect (.NET Focused)

Remote | Contract Full-Time or Part-Time Considered

Overview

We are seeking a highly experienced Facebook API Architect to evaluate, redesign, and optimize an existing social media integration architecture within a SaaS platform. This individual will play a critical role in reviewing current implementation decisions, identifying architectural gaps, and implementing scalable, sustainable improvements.

This is not a role for someone who has simply made basic API calls. We are looking for someone who has deep, hands-on experience working extensively with Facebook’s ecosystem, particularly the Graph API and Marketing/Ads APIs, and who understands the nuances of authentication, rate limiting, permissions, versioning, webhooks, ad objects, campaign management, and long-term maintainability.

The environment is primarily .NET-based, with some PHP components.

This opportunity is fully remote and open to part-time engagement for the right expert.

What You’ll Be Doing

• Conduct a comprehensive review of an existing Facebook API architecture
• Identify foundational architectural issues and recommend improvements
• Redesign and implement scalable, maintainable API integrations
• Optimize performance, reliability, and long-term maintainability
• Work closely with internal engineering leadership to guide architectural decisions
• Ensure proper handling of:
  • Facebook Graph API objects and permissions
  • Facebook Marketing / Ads API integrations
  • OAuth flows and token lifecycle management
  • Webhooks and event-driven architecture
  • Rate limits, error handling, and version changes
• Provide strategic guidance on best practices for large-scale social platform integrations

What We’re Looking For

Required Experience

• Extensive, deep hands-on experience with Facebook APIs
  • Facebook Graph API
  • Facebook Marketing / Ads API
• Experience building or maintaining systems that:
  • Manage posting across Facebook and other social platforms
  • Support advertising, campaign management, and monitoring
  • Handle complex API workflows at scale
• Strong architectural experience within .NET / C# environments
• Experience evaluating and refactoring existing API architectures
• Strong understanding of OAuth, webhooks, API versioning, and rate limiting strategies
• Experience in SaaS or multi-tenant application environments

Preferred Experience

• Experience integrating with additional social media APIs (Instagram, LinkedIn, X, etc.)
• Some familiarity with PHP (secondary to .NET)
• Experience working on advertising or marketing technology platforms
• Prior experience cleaning up or re-architecting legacy API integrations

What Success Looks Like

• Clear identification of architectural weaknesses in the current Facebook integration
• A redesigned, scalable approach aligned with Facebook API best practices
• Improved stability, maintainability, and performance
• Documentation and strategic guidance that strengthens the internal development team
