Zealand - Senior Software Developer

The Role

As a Senior Software Developer in our core delivery team, you'll help craft interesting, challenging systems that are beyond routine feature work, alongside a team of highly skilled peers who value software craftsmanship and autonomy.

You'll work in an environment that prioritises technical excellence, curiosity, and forward-thinking design. We are looking for someone who is excited by emerging technologies and wants to make a tangible difference in the way people interact with digital systems.

We offer a culture built on trust, continuous learning, and meaningful impact. You'll join a team that values integrity over ego, and clarity over complexity.

Propellerhead operates a hybrid working model (work from our office and from your own home). While we prefer our NZ-based team to be located in Auckland, we are also welcoming applications from international developers who would like to relocate to Auckland.

If you are ready to work on real problems with real impact, and help lay the groundwork for what comes next we would like to hear from you.
