Descripción del empleo

Senior / Staff Software Engineers | Node.js | TypeScript | AWS

Build from scratch. Own the architecture. Make a genuine impact.

We're partnering with a growing Australian fintech business making a significant investment in its engineering capability.

We're looking for experienced Senior and Staff Software Engineers with strong Node.js, TypeScript and AWS experience to join a newly forming engineering team and help build a business‑critical platform from the ground up.

This isn't a role maintaining legacy systems or simply delivering tickets. You'll have genuine ownership, influence over technical decisions and the opportunity to build modern, scalable software that sits at the heart of the business.

The Opportunity:

The initial focus is developing a new Credit Decisioning Engine and the backend services supporting internal credit workflows.

You'll help design and build a modern, cloud‑native platform, integrating with external financial services, banking providers and internal systems.
Future projects will extend into lending platforms, financial integrations and data services.

We're hiring across both Senior and Staff levels, with responsibilities aligned to your experience.

• Senior Engineers: Own the design, development and delivery of significant backend services, taking solutions from concept through to production.
• Staff Engineers: Take broader ownership of architecture, technical direction and engineering standards while remaining deeply hands‑on with code.

Both are individual contributor positions with no direct reports.

What You’ll Be Doing

• Design, develop and maintain scalable backend services using Node.js and TypeScript.
• Build and operate cloud‑native applications and infrastructure on AWS.
• Help architect and deliver a greenfield credit decisioning platform.
• Develop REST APIs and integrations with third‑party financial services.
• Design reliable, secure and maintainable distributed systems.
• Work with relational databases, SQL and complex data integrations.
• Implement Infrastructure as Code, CI/CD pipelines and automated testing.
• Build observability, monitoring, logging and alerting into production services.
• Take end‑to‑end ownership from technical design through to deployment and ongoing support.
• Contribute to engineering standards, code reviews and technical decision‑making.
• Use modern AI‑assisted development tools to improve engineering productivity.

At Staff level, you’ll also play a key role in shaping architecture, influencing technical decisions and mentoring other engineers.

What We’re Looking For

• Deep hands‑on experience with Node.js and TypeScript building production‑grade backend applications.
• Strong AWS experience, including designing, deploying and operating cloud‑native services.
• Solid understanding of distributed systems, microservices and API design.
• Experience integrating third‑party platforms and services.
• Strong SQL and relational database experience.
• Practical experience with Infrastructure as Code and CI/CD.
• A strong approach to automated testing, reliability, performance and observability.
• Confidence taking ownership of complex engineering problems.
• Excellent communication skills and a collaborative mindset.
• Experience using AI coding tools effectively, backed by sound engineering judgement.

For Staff‑level applicants, we’re particularly interested in engineers who have demonstrated architectural leadership, influenced engineering standards and delivered complex platforms at scale, without stepping away from hands‑on development.

Experience in fintech, banking, lending, payments or regulated environments would be advantageous, but isn’t essential.

Why Join?

• Greenfield engineering: Build a major platform from the ground up.
• Modern technology: Work extensively with Node.js, TypeScript and AWS.
• Real ownership: Influence design, architecture and how systems are built.
• Stay hands‑on: Significant technical responsibility without people management.
• Complex engineering challenges: Distributed systems, financial integrations and cloud architecture.
• Career opportunity: A chance to make a genuine impact within a growing engineering function.

Working Arrangements

Sydney CBD | Permanent | 5 days onsite

This is an office‑based opportunity requiring five days per week in the Sydney CBD office, with a strong emphasis on collaboration as the engineering team and platform are established.
