Integration Developer (full-stack)

About the Role

You will build the connective tissue of Dvxel’s AI platform — integration services that connect our systems to HubSpot, Google Analytics 4, booking platforms, and every other tool our clients depend on. You turn API documentation into reliable, fault-tolerant integration code. You think carefully about what happens when third-party APIs go down, rate limits are hit, and webhooks arrive out of order.

WHAT YOU WILL DO

• Build and maintain integration services connecting the AI platform to CRM, analytics, and booking systems
• Implement reliable webhook processing with idempotency, retry logic, and dead-letter queue handling
• Design and maintain event-driven data pipelines using AWS SQS and SNS
• Lead the design and development of the core platform API in collaboration with the Platform Architect and AI Engineer.
• Build and maintain internal REST APIs using FastAPI, following clean architecture and versioning best practices.
• Handle OAuth 2.0 flows, API key management, and secure credential storage via AWS Secrets Manager
• Write integration tests ensuring connector reliability across third-party API version updates
• Monitor integration health and respond proactively to third-party API failures

EXPERIENCE REQUIRED

• 3–5 years of backend development experience
• Strong experience building and maintaining third-party API integrations
• Experience with AWS services including SQS, SNS, and Secrets Manager
• Solid understanding of REST API design, webhook patterns, and OAuth 2.0
• • Hands-on experience with FastAPI (or similar Python frameworks such as Flask/Django REST)
• Experience with event-driven architecture and message queuing systems
• Comfortable debugging integration failures across multiple interdependent systems
