Senior Full-Stack Software Engineer (.NET / C#) - SaaS Startup

At Zipline, our modern HealthTech, loved SaaS products are in growth mode

We've got meaningful product work ahead, big Aussie customers relying on us, and a team obsessed with shipping fast, smart, customer-impacting software.

We're after a very particular type of engineer... Not a code-shipper. Not an architecture physicist...

But a product builder.

About You

• You're a product-minded engineer... you think in customer problems, not tickets or ‘stories'
• You're basically a product designer, but in code - creating elegant, simple solutions
• You ship fast - taking a pragmatic, well-scoped, outcome-first, not perfection-first approach
• You enjoy communicating with customers, exec, support & sales - not just PMs & other engineers
• Comfortable across the stack (.NET + Angular) - owning outcomes

• You value clarity, first principles, and making smart trade-offs
