Job description

2 x Mid-Senior Full Stack Software Engineer

While most teams are still talking about AI-first engineering. We're doing it.

Scalapay is a Wollongong-based Fintech with international reach, helping shoppers and merchants pay more flexibly. We're growing, and we're hiring two experienced Full-Stack Software Engineers to join our Experiences and B2B Platform teams.

Wherever you land, you won't be a small cog in a big machine. You'll take features from idea to production and see your work make a real difference.

About the role

At Scalapay, AI-first is how we work every day, not a slide in a strategy deck. You'll write sharp specs and technical designs, AI coding agents like Claude Code take on the heavy lifting, and you direct, review and test what they produce. You spend less time on boilerplate and more on what great engineers do best: architecture, tricky problems, and making things fast, robust and scalable.

You’ll own features from first idea to production across the full stack, working in Node.js, TypeScript and React.js, with NestJS and Next.js, MySQL, DynamoDB, Redis and modern CI/CD pipelines. Experiences team builds the products shoppers see and touch every day. B2B Platform team builds the tools and integrations our merchant partners rely on. Your work ships fast in both teams, and you'll see the impact.

Scalapay moves quickly. Priorities shift, ideas get tested fast, and there's always a new challenge. Through all of that, the culture is the reason people stay. The team is supportive and collaborative: people share their knowledge, give honest feedback, and back each other through every sprint, stand-up and retro. You'll get room to grow, room to bring your own ideas, and a team that wants you to succeed.

About you

You're an experienced full-stack engineer who does your best work when things are moving fast.

Technical expertise within Agile environments using Node.js, TypeScript and React.js, with NestJS and Next.js, MySQL, DynamoDB, Redis and modern CI/CD pipelines. Our preferred cloud environment is AWS.

Ideally you've worked in fintech or financial services, so you know what's at stake when software handles people's money, and you care about getting it right.

You think critically and ask "why" before "how".

You can pull apart a complex problem, weigh the trade-offs, and land on the solution that makes sense, not just the first one that works. That same judgement makes you good at reviewing what AI agents produce: you can spot what's off and know how to fix it.

You're adaptable and you enjoy a fast pace. When priorities shift you adjust without losing momentum, and you'd take a dynamic environment over a predictable one any day.

You're also a genuine collaborator. You share what you know, welcome a challenge to your thinking, and want the team to win, not just your own work.
