Full Stack Developer

This is an exciting opportunity to join a technology leader working on some of the most exciting and innovative 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. You will work extensively with 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.

Qualifications:

• Bachelor's degree in Computer Science, Software Engineering, or a related field
• Experience: 2–5 years of professional full-stack development experience.
• Strong TypeScript/JavaScript​: Deep proficiency in modern TypeScript, React (Hooks, Context), and Node.js asynchronous programming.
• Backend Polyglot: Significant experience with Node.js REST APIs, plus a working knowledge of (or strong willingness to work with) Java/Spring Boot.
• Database Skills: Comfortable with SQL (MySQL/Postgres) and ORMs (TypeORM, Hibernate, or Prisma).
• Real-Time Concepts: Understanding of WebSockets, Pub/Sub patterns, and state synchronisation between client and server.
• Adaptability: The ability to context-switch between frontend codebase and a structured "enterprise" backend codebase.

"Nice to Have" Skills (The Differentiators)

• Telephony/WebRTC: e.g. Experience with Twilio (Programmable Voice/Video/Conversations) is a massive plus.
• State Management: Familiarity with diverse state libraries: Zustand, TanStack Query, or Redux Toolkit.
• JHipster: Previous exposure to JHipster-generated applications.
• Cloud Ops: Experience with Docker, CDK, and AWS services.
• Modern CSS: Mastery of Tailwind CSS and utility-first styling.

What Success Looks Like (First 90 Days)

1. Environment Mastery: You can run the entire ecosystem locally (Docker, Node, Java services) and understand how the apps communicate.
2. Cross-Stack Shipping: You have successfully merged a PR that touches the frontend (React) and one that touches the backend (Node or Java).
3. Real-Time Debugging: You can trace a dropped call or a missing message event from the UI through the WebSocket server to the database and identify the root cause.
