Job Description

We are seeking a Senior Full Stack Engineer specializing in AI and Conversational Systems to join our engineering organization in Sydney.

In this hands-on role, you will design, build, and operate production-grade conversational interfaces and generative AI features—including AI Coach solutions, real-time CoPilot streaming experiences, and intelligent agent workflows. You will bridge advanced AI tooling (Vertex AI, Dialogflow CX, AgentStudio) with up-to-date frontend and backend architectures (React, WebSockets, Node.js, Java) while applying rigorous engineering practices to handle non-deterministic model behaviour.

Key Responsibilities

- Conversational & Generative AI Development: Design and build intelligent agent workflows, conversational flows, and generative AI features using Dialogflow CX, Vertex AI, AgentStudio, and advanced prompt/context engineering techniques.

- Real-Time AI Frontend Engineering: Develop high-performance,



responsive user interfaces using React, Vite, Tailwind CSS, and Storybook, integrating WebSockets for real-time conversational and CoPilot streaming capabilities.

- Backend & API Integration: Build and maintain scalable backend services and API layers (Node.js/TypeScript, Java, Apigee) to support secure, low-latency communication between front-end applications and AI model providers.

- AI Quality & Testing Engineering: Implement robust evaluation, testing, and monitoring frameworks for AI-enabled features—focusing on accuracy, response latency, guardrails, prompt regression, and handling non-deterministic model behaviour.

- Cross-Functional Collaboration: Partner with product managers, AI architects, UX designers, and platform engineers to deliver secure, production-ready AI capabilities at enterprise scale.
