Senior Backend Developer (NodeJS)

Dodo is an AI-powered communication platform transforming how specialty clinics—especially veterinary clinics—connect with their customers. We build intelligent voice AI and SMS solutions that automate conversations, streamline appointment scheduling, and deliver real-time analytics. Our mission is to make healthcare communication smarter, more efficient, and more human.

We’re a reimagining how specialty clinics operate through advanced voice AI and multi-agent systems. Our platform powers intelligent, real-time phone and SMS conversations for healthcare, blending state-of-the-art AI with secure, scalable backend infrastructure. Join a small, ambitious team where your work directly shapes the future of patient engagement and care delivery.

What You’ll Do

• Architect and build scalable backend services in Node.js and TypeScript
• Design and integrate RESTful and GraphQL APIs (internal and third-party)
• Develop and optimize real-time voice AI systems, including telephony (Twilio, WebRTC) and conversational agents
• Contribute to the design and implementation of multi-agent AI systems for complex, stateful healthcare workflows
• Work with LLMs and help shape our AI engineering frameworks (tool calling, retrieval, orchestration)
• Optimize deployments and infrastructure on GCP (Kubernetes, containers)
• Improve CI/CD pipelines (Cloud Build, GitHub Actions)
• Collaborate with frontend, product, and AI teams to ship features fast
• Champion best practices for performance, scalability, and security

What We’re Looking For

• 5+ years of backend experience with Node.js and TypeScript
• 3+ years building real-time communication systems (WebRTC, WebSockets, or telephony)
• Experience with voice AI, conversational agents, or multi-agent system architectures
• Experience in healthcare software (HIPAA compliance) or deep real-time systems expertise (both is a plus)
• Startup mindset: You thrive in fast-paced, high-ownership environments

We use a modern TypeScript monorepo setup with a stack including Node.js, Express, Next.js, PostgreSQL, Redis, and Google Cloud. Our platform integrates advanced AI/ML (OpenAI, Groq, LangChain, LangGraph) for natural conversations, and leverages Twilio and WebRTC for telephony/SMS. We solve challenging problems in real-time communication, multi-tenant architecture, and AI-driven workflow automation through multi-agent systems.
