Staff Software Engineer (Full‑Stack) – ASX Listed FinTech

Sydney | 2 days in office | Permanent Resident or Citizen required

Are you a Senior or Staff‑level Engineer who thrives on solving complex problems, owning systems end‑to‑end, and setting technical direction, while still being deeply hands‑on?

I’m hiring for a fast‑growing, profitable, ASX‑listed FinTech that is scaling its engineering capability and looking to add a Staff Software Engineer to a high‑performing team. This role operates very similarly to a Technical Lead , but with a stronger focus on technical depth , architecture , and ownership , rather than people management.
  
The Role – What You’ll Do
As a Staff Software Engineer, you will be a senior technical authority across core customer-facing and internal systems. Expect to work across the full stack and own major architectural decisions while delivering hands‑on engineering outcomes.

You will:
  • Lead the architecture, design, and delivery of complex software systems and refactor major technical components.
  • Build and enhance microservices with Event‑Driven Architecture across high‑scale FinTech platforms.
  • Work across APIs, customer applications, credit & treasury systems, internal tooling, and more.
  • Drive technical initiatives and lead projects end‑to‑end, strong technical depth is key.
  • Solve ambiguous, high‑impact engineering challenges while maintaining long‑term technical health.
  • Mentor senior engineers and uplift engineering capability across your domain.
  • Get exposure to data platforms, DevOps, observability, and AI‑driven initiatives.
This role is perfect for engineers who enjoy operating as a hands-on technical leader , owning architecture while still writing high‑quality code.

Tech Stack & Engineering Environment
You don’t need to tick every box, strong engineering fundamentals matter most, but experience across the following is highly valued:

Core Stack:
  • C# / .NET Core
  • React (or strong frontend experience in another modern framework)
Engineering Practices:
  • TDD, BDD, SOLID principles
  • Strong focus on maintainability, performance and clean architectural patterns
Cloud & Platform Engineering:
  • AWS experience (highly beneficial)
  • Microservices & Event‑Driven Architecture
  • Understanding of Distributed Systems and Domain‑Driven Design
  • Familiarity with infrastructure, DevOps, CI/CD and scalable cloud environments
Database:
  • SQL Server / PostgreSQL expertise a plus
Why This Role?
  • Join a high‑growth, high‑impact, engineering‑focused ASX FinTech
  • Real ownership across the full SDLC, build it, run it, improve it
  • Work closely with senior leadership and shape long-term platform strategy
  • Career pathways into Principal Engineer / Architecture / Domain Lead
  • Exposure to modern cloud, data, and AI initiatives at scale
  • Work with smart engineers in a collaborative, lean environment
If you're a senior, hands‑on engineer who wants real scale, real ownership and a role with both depth and influence - this is for you.
