• Design and build the APIs and webhooks that connect the application with telephony services, the voice-agent platform, and data stores.

• Build real-time functionality for call and agent activity where required.

• Write automated tests and maintain code quality across the frontend and backend.

• Participate in code reviews and contribute to the team's engineering standards and practices.

• Ship features through the development and CI pipeline and take ownership of them through production.

• Strong TypeScript or JavaScript experience with React, along with strong Python experience using FastAPI, Django, or a similar backend framework.

• Strong understanding of relational databases and API design.

• Experience building and operating real-time application features using WebSockets, event streams, or similar technologies.
