About the role

About the company
A Kiwi–American start-up with strong funding and open-source traction is rethinking how teams work with AI. The mission: stop teams from spinning the wheel faster in the wrong direction by solving the context and alignment problem when shipping product at speed. 

Why this role matters
This is a founding engineer role. You’ll help design and deliver the backbone of a platform where AI output and human direction finally stay in sync. Joining this early means your choices will shape the architecture, the standards, and the way the product evolves. For engineers who want influence, ownership, and a chance to set the pace, this is that rare moment.

What you’ll do

  • Ship full-stack features with Next.js / Nest.js / Node.js, interacting with PostgreSQL databases
  • Develop workflows and prompts that get LLMs delivering in production
  • Implement RAG based systems (embeddings, chunking, vector DBs)
  • Set engineering standards and mentor others

What you’ll bring
  • 5+ years of full-stack engineering experience
  • Proven experience shipping performant systems
  • Hands-on with AI tools (prompting, LLMs, RAG)
  • Hunger to solve hard problems and thrive in early-stage speed

Why join
  • Up to NZD $250k + equity
  • Choice of Auckland or US based
  • Culture built for builders: ownership, freedom, and a team that has your back
  • A chance to help shape a platform already proven with a global developer community

For engineers who want to do more than keep the wheel spinning - who want to set its direction - this is the opportunity.
