Why this role exists (and why you will like it)
Modern stack with real engineering depth
You will work on a cloud-first platform with real integration complexity - APIs, workflows, data, compliance and AI features. This is proper product engineering, not UI churn or CRUD-only work.
Building features people actually use
This is a live product with paying customers. What you build ships to production and gets used daily, with clear feedback loops and real accountability.
Small team, high ownership
You will join a small, senior-leaning team where engineers own work end to end and influence technical direction. Decisions are made close to the code, with direct access to the founder and minimal bureaucracy.
User-centred, domain-driven development
The product is built close to the domain. Engineers work directly against real user workflows, not abstract requirements, leading to better problem framing and more satisfying outcomes.
Early-stage momentum, not early-stage chaos
The business has runway secured and customers onboard. There is room to shape patterns, improve quality and reduce technical debt over time, without firefighting or starting from zero.
The role
You will work as a full stack engineer across C#, ASP.NET Core, React, JavaScript and SQL, owning features from design through to production. You will collaborate closely with the team and play a hands-on role in delivering and evolving a practical, product-led AI roadmap.
What we are looking for
-
Strong experience with C# and ASP.NET Core
-
Solid React and modern JavaScript experience
-
Experience working with SQL and relational databases
-
Commercial experience building Azure-based Functions and Services
-
Understanding of modern web application architecture and API design
-
Comfortable owning work end to end and iterating based on feedback
-
Sydney based with full Australian working rights
-
A Computer Science background is valued - the current team are all CS graduates
The environment
-
Cloud-native, product-focused engineering
-
Low ceremony, high trust
-
Engineers treated as problem solvers, not ticket-takers
-
AI as part of the roadmap, not marketing fluff
If you enjoy building real software, shipping often, learning from users and having genuine ownership over what you create, this role will feel like home.
