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.
Why Zipline?

  • Profitable + scaling - big growth ahead, lots of opportunity
  • Real-world impact - the things you build keep vulnerable people safe
  • Human-first culture - we're both high performance and high care
  • No games or politics - just a genuinely supportive, humble, high-performing team
  • Any city in Aus - modern offices & flexible hybrid work

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 like small squads, rapid co-discovery & co-delivery loops
  • You value clarity, first principles, and making smart trade-offs

______
