Job Description
Senior Software Engineer - Own What You Build
North Sydney (Hybrid) | $160k - $190k + Super (+ bonus)
Not every engineering role is about tickets, stand-ups, and layers of approval.
Some are about ownership.
About being heard.
About building things that actually get used - at scale, globally.
This is one of those roles.
We’re partnering with a high-growth, profitable tech business operating globally across identity, data, and fraud prevention. Their platform processes billions of records and is used by major enterprise clients.

Build data products, APIs, and applications at global scale
-
Work with multi-billion record datasets across multiple geographies
-
Solve real-world problems in identity, data matching, and fraud prevention
-
Contribute to Snowflake-based products and emerging AI initiatives
-
Work directly with founders - no layers, no red tape
This is hands-on, high-impact work - not internal tooling.
What They’re Looking For
-
Strong communication skills (this is critical)
-
A doer - someone who takes ownership and drives outcomes
-
Pragmatic, solutions-focused mindset
-
Comfortable working with messy, large-scale data
-
Experience building production systems end-to-end
Tech-wise, you’ll likely have experience with:
