Backend Developer (Node.js)

About the Role

We're working with a fast-scaling Sydney-based tech company to find a Backend Developer who can take ownership of complex, high-throughput systems built on Node.js and TypeScript. This is a permanent, full-time role embedded within a collaborative engineering team that ships meaningful product regularly and values technical rigour over process overhead. If you're the kind of developer who cares deeply about clean architecture and wants real influence over how systems are built, this one's worth a look.

What You'll Be Doing

• Design, build, and maintain scalable backend services and APIs using Node.js and TypeScript

• Develop and optimise GraphQL and REST APIs consumed by web and mobile clients

• Manage and tune PostgreSQL databases, including schema design, query optimisation, and migrations

• Architect and deploy cloud infrastructure on AWS, working with services such as Lambda, RDS, ECS, and API Gateway

• Collaborate closely with frontend engineers and product teams to define technical requirements and deliver features end-to-end

• Contribute to code reviews, technical documentation, and engineering best practices across the team

• Identify and resolve performance bottlenecks, reliability issues, and security vulnerabilities in production systems

What We're Looking For

• 3+ years of professional backend development experience with Node.js and TypeScript — this is non-negotiable

• Strong hands-on experience with PostgreSQL, including complex query writing, indexing strategies, and database design

• Solid understanding of RESTful API design principles and practical experience building production-grade endpoints

• Experience with GraphQL — schema design, resolvers, and ideally working with tools like Apollo Server

• Comfortable working with AWS cloud infrastructure; familiarity with IaC tools such as Terraform or CDK is a plus

• Demonstrated ability to write testable, maintainable code with good test coverage using frameworks like Jest

• Strong communication skills and the ability to work autonomously in a fast-paced, product-driven environment

What's On Offer

• Competitive salary of $130,000 – $155,000 + superannuation, reviewed annually based on performance

• Flexible hybrid working arrangement based in Sydney, NSW — genuine flexibility, not just in the policy document

• A modern, well-maintained tech stack with real investment in tooling, infrastructure, and engineering quality

• Clear career progression pathways, with access to a dedicated learning and development budget for conferences, courses, and certifications

• A tight-knit engineering culture that values technical ownership, open feedback, and shipping work you're proud of
