About VetPawer and Ava

VetPawer builds Ava, a veterinary-native AI platform used by more than 985 animal hospitals. Ava answers phones, books appointments, handles prescription refill requests, and calls lapsed clients to bring them back. It works inside the practice management systems clinics already use.

Most of our customers are multi-location veterinary groups, so the systems you'll work on route calls and appointments across hundreds of clinics. We're a small, fully remote team led by founders who have built and sold a veterinary software company before.

The role

We're hiring a Senior Full-Stack Engineer who knows Node.js deeply and can own Ava's application layer end to end: the backend that powers scheduling, refills, and calling, the web front end used by clinics and pet owners, and the integrations that connect Ava to clinic systems. You'll report to our Product Owner and work closely with our integrations and infrastructure leads.

What you'll do

Build and maintain features in Ava's Node.js services, including scheduling, refill handling, multi-location routing, and outbound call campaigns

Improve the stability, performance, and test coverage of a production system that runs 24/7

Build front-end experiences for online booking, website chat, and clinic dashboards

Design and maintain REST APIs and webhooks, including data feeds for enterprise customers

Work with our Twilio voice stack and with LLM and voice AI services in production
