Job description

Jora New Zealand will close on 9th September 2026. Thank you for being with us, we are cheering you on as you continue your career journey.

Infainite is looking for an Agentic Software Engineer to design, build and deploy intelligent software systems that use AI agents to reason, act, integrate with tools and complete real-world tasks.

This is a hands-on engineering role spanning software development, AI architecture, enterprise integration and production deployment. You’ll work on customer-facing solutions as well as reusable Infainite platform capabilities, taking ideas from ambiguity through to working production systems.

We’re looking for someone who is technically strong, deeply curious and comfortable challenging conventional thinking.

At Infainite, we have a healthy disdain for the status quo. We value people who question assumptions, push past “that’s how it’s always been done,” and are willing to explore ideas that may initially seem unconventional. We want thoughtful contrarians, people who can form strong views, test them against reality and change their minds when the evidence demands it.

The right person will be comfortable working in ambiguous problem spaces, translating business needs into technical architectures, and taking solutions from concept through to production.
