We are looking to hire a SMS Messaging Workflow Engineer (Telnyx / KYC Compliance) to build a compliant automated text messaging system.
The system will send an initial consent request text message, wait for the recipient’s reply (YES / NO / STOP), and then automatically send a follow-up message only if consent is granted. All inbound and outbound messages must be logged in a database for audit and compliance purposes. If a recipient replies STOP, the system must permanently block future contact to that phone number.
The workflow must be built using Telnyx messaging APIs, secured webhooks, and a PostgreSQL database. The developer will be responsible for creating the message state logic, webhook endpoint, database schema, opt-out handling, and delivery logging required to meet TCPA and consent record-keeping requirements. Code should be clean, well-structured, and documented for internal technical handoff.
Responsibilities
Develop consent and follow-up SMS workflow using Telnyx Messaging APIs
Implement webhook logic to process inbound replies (YES / NO / STOP)
Create and deploy a PostgreSQL audit logging system (5+ year retention)
Implement permanent opt-out suppression logic
Secure all endpoints (HTTPS + Telnyx signature verification)
Provide documentation and a simple admin reference for internal staff
