Description

About Us

Fintech Services Australia is a modern Australian fintech on a mission to make finance work better for people. We bring together technology, data, and deep lending expertise to deliver innovative financial solutions – and we’re proud to be recognised as Australia’s most accessible non-bank lender, winning back-to-back awards in 2023 and 2024.

With a major platform transformation underway and an ambitious product roadmap ahead, this is a rare opportunity to join a team that is genuinely redefining what a fintech engineering culture looks like.

 

About the Role

We’re looking for a Senior Developer who takes pride in craft – someone who excels in use of AI to design and deliver robust, scalable solutions while helping elevate the engineers around them. You’ll work within our Product & Technology division, embedded in a cross-functional squad and reporting to our Tech Lead.

This isn’t a heads-down coding role. You’ll contribute to technical direction, drive quality standards, and play a meaningful part in shaping how we build.

 

Key Responsibilities

  • Design and deliver secure, well-architected solutions across the full loan lifecycle – from inception to production.
  • Lead technical design discussions and contribute architectural improvements that cut complexity and improve maintainability.
  • Deliver high-quality software predictably within our agile framework, upholding strong engineering practices including testing, code quality, and SDLC principles.
  • Own the quality and maintainability of the features and components in your domain – including incident response and preventative improvements.
  • Mentor and support junior engineers, provide constructive code reviews, and elevate overall squad capability.
  • Identify and introduce reusable patterns, tooling improvements, and engineering practices that make the whole team faster.
  • Evaluate and responsibly leverage AI-assisted development tools to enhance productivity and code quality.

 

What you’ll bring

  • 5+ years’ experience as a Developer in a commercial environment, with 2 years as a Senior.
  • Solid proficiency across .NET, with bonus points for JavaScript, TypeScript, React, and Git.
  • Hands-on experience with Azure cloud services – App Services, Functions, Azure SQL, Blob Storage, and Azure DevOps is desirable.  Alternate cloud vendors are acceptable.
  • Experience designing and deploying cloud-based solutions with security, scalability, resilience, and recovery in mind.
  • Strong use of AI tooling for 12 months or more is required, ideally ChatGPT Codex or Claude Code, in an industry best practice manner.
  • Familiarity with monitoring tools (NewRelic, Azure Monitor) and API testing tools (Postman, SwaggerHub).
  • Strong grasp of SDLC principles and agile methodologies such as Scrum, Kanban, Lean, and Continuous Delivery.
  • Ideally bring a background in Test Driven Development experience, or integration of AI/ML capabilities into production systems.
  • Tertiary qualification in Computer Science or equivalent experience; relevant vendor or technical certifications are a plus.

 

Why you’ll love working here

  • Real ownership – you’ll shape technical direction, not just execute tickets.
  • A clear career pathway toward Tech Lead and Principal Engineer.
  • The freedom and agility of a company that makes decisions fast – no endless layers of approval.
  • Flexible working conditions to keep life and work in balance.
  • A collaborative, open workspace with good coffee, modern amenities, and the energy of a team building something meaningful.
  • Access to training and development to support your growth.
  • A conveniently located Perth CBD office, 50m from Elizabeth Quay Station.
