Full Stack Engineer (React /Node.js)

About the Role

We're looking for a talented engineer who thrives in a flow-based development environment and enjoys building complete end-to-end product experiences—from backend services to polished front-end interfaces. You'll work closely with cross-functional teams in a product-focused Agile setting, contributing to a fast-paced, globally scaled platform.


What You Will Do

  • Implement flow-based development, designing complete workflows from services to APIs to user interfaces.

  • Operate within a cross-functional, product-focused Agile environment.

  • Collaborate with fellow developers to architect solutions for complex technical requirements.

  • Participate in code reviews and maintain high engineering standards.

  • Develop high-performance UI components and APIs in line with established specifications.


Key Responsibilities

  • Architect, develop, and maintain scalable, distributed, event-driven systems and APIs using TypeScript, React, and Node.js.

  • Build complete product workflows—from backend services to APIs to front-end components.

  • Work collaboratively within a product-centric Agile team.

  • Participate actively in code review processes and uphold engineering best practices.

  • Engineer performant, reliable, and maintainable UI components and APIs.

  • Contribute to the architecture and delivery of a globally scalable betting platform.


Requirements

  • Strong JavaScript (ES6+) fundamentals and advanced experience with TypeScript.

  • Proficiency with React (modern hooks-based architecture) and Node.js (latest versions).

  • Solid understanding of software engineering principles: error handling, testing strategies (test pyramid), dependency injection, and design patterns.

  • Experience with event-driven and message queuing systems such as Kafka, Google Pub/Sub, RabbitMQ, or AWS SQS.

  • Excellent teamwork, communication, and collaboration skills.


Desired Skills

  • Experience with NoSQL databases (Couchbase, Elasticsearch) and familiarity with SQL, NoSQL, and Elastic query languages.

  • Knowledge of modern React libraries (e.g., React Query).

  • Proficiency with unit testing tools (React Testing Library, Jest) and integration testing frameworks (Playwright).

  • Familiarity with CI/CD pipelines and containerization tools such as Docker, Kubernetes, Helm, Jenkins, or GitLab.

  • Experience designing or scaling high-throughput, high-availability systems.


Benefits

  • A beautiful new Barangaroo office, just steps away from Wynyard Station.

  • A dedicated sports hub—perfect for table tennis, darts, and friendly competitions.

  • Exceptional coffee from our in-house barista, crafted just the way you like it.

  • A variety of fun social events throughout the year (the Melbourne Cup is a highlight!).

  • Enjoy wagering competitions for a bit of light-hearted fun.

  • Ongoing professional development to support your career growth.

  • Employee share program to share in our success.

  • A range of wellness benefits to support your wellbeing.

  • Life insurance and income protection for added peace of mind.

  • Genuine work–life balance and flexible working arrangements.
