AI Real-Time Full-Stack Engineer (Remote) (New South Wales)

This is an exciting opportunity to join a technology leader working on some of the most exciting and creative projects in Australia. We are seeking a versatile Full-Stack Developer with expertise in Node.js, React, and Java/Spring Boot to join our engineering team in a full-time role, working remotely, but based in Sydney. We operate a complex real-time communication platform for correctional facilities and you will be capable of jumping between stacks to build secure video/voice/messaging features, maintain critical APIs, and refine user interfaces. If you are a TypeScript expert who isn't afraid of Java (or vice versa) and you love working on real-time systems involving WebSockets, Telephony and AI — this is the role for you. Key Responsibilities
- → Frontend Development (React/TypeScript): Build and maintain responsive UIs for multiple applications
- → Backend Development (Node.js & Java): Design and maintain scalable backend services — Node.js/Express for real-time media handling and Java/Spring Boot for enterprise logic and data management
- → Real-Time Communications: Implement complex voice and video workflows using 3rd party SDKs, Socket.IO, and WebRTC
- → AI & Cloud Integration: Work with AWS (Transcribe, Rekognition, S3) and Google Cloud services to integrate live content moderation and transcription into our calls
- → Database & Infrastructure: Manage data across MySQL and Redis. Support containerized deployments using Docker and troubleshoot issues in production environments
- → Quality Assurance: Write comprehensive tests across the stack — Unit tests (Jest, JUnit), Integration tests, and E2E tests (Playwright) to ensure no regressions in critical communication flows Skills & Qualifications
