Workflow Automation Platform | Node.js, Golang, React
Sydney | Up to $130K + super | Hybrid (2 days in-office)
Imagine building the infrastructure that powers how work gets done, not just for one company, but for dozens of global enterprises. That’s the opportunity here.
You’ll be joining a fast-growing product company backed by Australia’s top investors, already partnered with global enterprise clients and expanding into the US. Their platform is mission-critical for customers - streamlining, automating, and scaling business operations.
As the platform scales, we’re hiring a backend-leaning full stack engineer to help evolve and strengthen the core architecture - particularly in Go and Node.js.
You’ll join a collaborative, tight-knit team in Sydney, working closely with experienced engineers and company founders. There’s meaningful architectural work to lead or contribute to, and your impact will be felt across the product from day one.
What’s in it for you?
- Be part of a company scaling fast with real customers and technical complexity
- Tackle meaningful architectural challenges - refactoring legacy systems, improving service boundaries, and building scalable backend solutions
- Contribute to a product that’s growing in both depth and reach, with autonomy to own backend projects from design to production
- Opportunities to support across the stack - and to mentor or be mentored depending on your strengths
- Join a product-first company where engineers are involved in decision-making, not just execution
- Work in a flexible hybrid model - two days a week in the office, with the rest remote
About you
- 2 - 4 years of experience as a backend or full stack engineer with strong Go or Node.js skills
- Experience building APIs and backend services that are simple, scalable, and maintainable
- Comfortable working with frontend code (React/TypeScript) when needed
- Pragmatic thinker who avoids overengineering and values clean code
- Experience in product-focused teams or startups where you’ve worked closely with product and design
- Collaborative, proactive, and eager to take ownership in a high-autonomy environment
The stack
- Node.js, Golang
- React, TypeScript, Tailwind
- AWS, Docker, Kubernetes
