About this role

Role overview Build and maintain integrations that let AI agents complete actions in external business systems, such as booking appointments, creating records, and sending messages. The work spans calendars, payment providers, CRMs, and messaging tools, with a focus on making integrations dependable when real-world issues arise.

Responsibilities - Build and maintain integrations with calendar, payment, CRM, and messaging services. - Handle authentication, time zones, retries, rate limits, and duplicate requests. - Test realistic failure scenarios and fix integration issues. - Write clear setup documentation for customers and support colleagues. - Help the product team assess and prioritize future integrations.

Requirements - Experience integrating third-party APIs, including OAuth, webhooks, and rate limits. - Backend development experience in a language such as TypeScript or Python. - Careful handling of edge cases and a habit of documenting them. - Ability to explain technical problems clearly to non-engineers. - Relevant experience may include SaaS integrations, booking, payment or CRM tools, or automation platforms combined with custom code.

Benefits and work setup - Remote contract with flexible hours; compensation starts at $4,000 per month. - Freelancers and solo agencies may continue working with their own clients. - The selection exercise has no time limit. It involves connecting an agent to a test calendar, presenting times in a customer’s time zone, booking after confirmation, testing booking and error scenarios, and recording the results.
